    For quite a long time already I am asking myself if this is topic on future aircraft carrier or on its aircraft!!!???

    hmm perhaps I'm wrong but is there any CV without fighters? dunno dunno dunno if you have doubts just ask moderator Razz Razz Razz

    If you are going to be a dick about it there is no point in a proper discussion... the MiG-29M from the 1980s has nothing at all to do with the MiG-29M and MiG-29M2 and MiG-29KR and MiG-35.

    I didnt find much about it, would be appreciate to learn more about it. Then what and when was changed comparing to 80s ?MiG-29M frame?




    then why all countries are developing new fighters? what's wrong with them?  

    The only further upgrade today for the MiG-35 design would be stealth, and lets see what that is actually worth when new radar designs enter service in the next couple of years...

    Would you answer my already couple of times asked question: why all countries prefer to build new fighters if upgrading old is so fine idea?  Suspect  Suspect  Suspect







    Do you suggest that any current fighter is as simple as Fokker VII ?  or technology doesnt change ?
    Modern aircraft are complex, but are not so fragile as a VSTOL fighter with high pressure gas tubes through their entire structure that are critical to its capacity to hover.


    VSTOL is more complex but not "fragile" that's your phobia not reality. 6g fighter is  same level of complexity complexity and "fragility" . Yet both Russia & US are developing them.





    Yak 141 had Yak-41, and its 152kN thrust engine destroyed the runway at Farnborough...

    3 times I've already asked - 0 links with source provided  by you. So we stop this ad nauseam mantra here.




    if that is the case do you think a 180 or 250kN would do better? Of course it would damage it even more if directed downwards... which means no main engine deflection downwards during takeoff or landing... ie conventional aircraft takeoffs and landings on conventional runways not covered in heat treated tiles.

    stop repeating ad nauseam same mantra, will ya? nobody is going to do continuous VTOL on unprepared locations. VTOL is required by navy mostly. Space on ships is scarce.
    BTW how do you think Su-57 can start so short for it weight if not  using of TV?



    Zhuk didnt function?!  Suspect  Suspect  Suspect Radar was based on zhuk and actually was developed.

    How did they develop it? The Yak-41 barely flew... there was no money.

    If barely flying means making barrel rolls , climbing as astonishing rate ?- then yes  (Aviation Week & Space Technologies about Farnborough ). Results were  good but then  navy and AF wanted more and more functionalities. 1987 was approved plan for low rate initial production in Saratov plant 292.  Factory tests to be started on  1987 and state on 1988.  In 1991 before crash ~90% of tests were completed. True no money killed many projects. Su-47, MiG-1.44 to. MiG-29k appeared only because of Indians not because it was so great fighter.



    It was cancelled just after a heavy landing on a carrier ruptured a main fuel tanks and the second prototype burned... the heavy landing was an attempted vertical landing where hot exhaust gas was ingested into the main air intake and the main engine stalled...

    True. But how about this: PAK FA after after almost 20 years of development was rejected by one main cosponsors. Poor stealth,no new engines, not really better than other new fighters but very expensive. One of prototypes failed and burned because of engine malfunction.  Thats why 20 years after start programme RuAF ordered 12 units.




    frame? (hook? frame strengthen? anit corrosion paint? CV landing electronics? ) so MiG-35 is carrying 500-700 more kgs in land version
    MiG have said the MiG-35 will be fully carrier capable.

    and same guy said that MiG-41 will be produced as from 2025th, didnt he?   Suspect  Suspect  Suspect
    Navalized fighter weights 500-700 more. Then did he tell potential customers that this is already navalized and heavier fighter or he was just bullshiting potential customers? like they have no  experts on their own.  





    Ka-31 is Airborne Early Warning...  a radar in the sky. What they actually need is an Airborne Warning And Control... that collects radar data and processes it and turns it into commands... vastly less data transmission, and vastly more useful and less conspicuous.

    yeah in 70s-80s data transmission was suspicious indeed. Not in 2030s tho. You see AEW&C can be realized in many ways, IMHO chopper is worse than drone. Both ceiling and duration fo flight makes drone a better option.



    The VMF could have similar tiltrotor tankers for its STOVLs, tiltrotors & helos.
    How? They don't have any tiltrotors...

    They actually do. UAV Fregat already has working proof of concept. VDV requested own tiltrotor (perhaps will be competing with high speed helo).
    Long before any CV is gonna be  launched tilltrotor can be reality.

    Look what we have here  Razz

    Russia's ship design bureau comes up with catamaran aircraft carrier concept

    The manufacturer stated that the ship’s underwater part is the project's 'key distinguishing feature'

    MOSCOW, October 2. /TASS/. The Krylov State Research Center has come up with a fundamentally new design concept of what may become Russia’s future semi-catamaran aircraft carrier, the center’s spokesman told TASS.

    The model of a future non-nuclear multirole aircraft carrier was presented for the first time at the Army-2018 forum at the end of August. The proposed project has no name yet.

    "The semi-catamaran design of the ship’s underwater part is the project’s key distinguishing feature," the spokesman said.

    Normally catamarans have two parallel hulls and a superstructure platform connecting them. The proposed semi-catamaran hull will resemble a dovetail, bifurcating toward the stern.

    The company’s spokesman said the new design pattern’s main advantage was a large flight deck (as wide as that of heavy aircraft carriers) and smaller displacement. The flight deck area is a crucial factor for the number of planes the ship can carry.

    "An average displacement ship is capable of carrying a full-scale air wing," the specialist said.

    No V-shape hull aircraft carriers have been built so far.

    Parameters

    The Krylov Center said the proposed aircraft carrier’s water displacement will be 44,000 tonnes, length - 304 meters, deck width - 78 meters, draught - 8.5 meters, full speed - 28 knots, and cruising range - 8,000 miles. The ship’s air wing will consist of 46 aircraft: 12-14 Sukhoi-33 fighters, 12-14 MiG-29K/KUB fighters, four early warning and command aircraft and 12-14 Ka-27 helicopters.

    Russia’s only medium class aircraft carrier The Admiral Kuznetsov having a far greater displacement (59,000 tonnes) carries the same air group - up to 52 planes and helicopters.

    This would explain the big divergence between the size of a conventional flight deck and the one of the new light carrier proposal. Very good and deserving of credit to innovate in CV configuration after some many decades of rather unchanged designs thumbsup

    Su-57 can take off in very little space because, even fully loaded, will have a T/W ratio really close to one (that means, it could almost take off vertically like a rocket) and will be further helped by a ski jump. This considering izd. 30 engines will be in line with claimed thrust of course. It will accelerate horizontally and the rotation will be done with help of the ramp. Don't really think TVC + LEVCONS can create lift through deflection which is more useful than the pure acceleration of the engines in the horizontal plane.

    Planes are designed to create lift when moving horizontally you know? And they are already very efficient at it, more than you seem to believe...

    You forgot to say that you need really high speed to get lift what is impossible to have in short take off without TV. Other solution is called a biplane. Su-57 will use ski jump on airfields?! why?

    As for TV deflection Yak-141 could (with gear arresters) have STOL 70m full load and no skijump.

    It is better if you make some numbers, really. How fast do you think a Su-57 would travel after 100 m take-off run accelerating @ ca. 1g? It is not slow at all, in fact it is enough for naval planes to go well past stall speed, especially when using a ski jump. You can watch videos and check your numbers easily. A fighter like MiG-29K covers this distance in the K in little over 5 seconds IIRC, starting from standstill. That is, by the end of the ramp it is close to 180 km/h, plus the wind + ship speed. So it takes off easily... in less space than a F-35B does  What a Face

    Why? it was same rhetoric GaryB is using against Yaks  Twisted Evil  Twisted Evil  Twisted Evil  BTW tell me what is not true in above statements?
    Not really. You are using cheap propaganda arguments which make no sense at all. Garry was trying to point out fundamental conceptual flaws (ingestion of hot air) that motivated to change to a lifting fan in the F-35. He is openly critic of STOVL but that does not mean he is using empty arguments

    isnt it the same as on pictures before? 44ktons? or Krylov is churning new variations on Marvell scale?
    Do not know what this Marvell scale is. The article refers explicitly to the carrier presented at Army 2018, so it must be the one already discussed in the forum and which raised doubts about its feasibility due to the very big size of its flight deck. Now we know the explanation about it was its innovative hull shape

    True but 44ktons, not nuclear pp what in Russias case sucks with scarcity of bases and nuclear powered liders? Full size air wing? 24-28 fighters from which 12 light migs? lol1 lol1 lol1

    French de Gaulle : nuclear powered, up to 35 fighters + 2 AWACS + 3 choppers. Project from 90s.
    What do you mean, that the de Gaulle is a good ship or that the light carrier from Krylov could be better if nuclear propelled? Both are most probably true.
    Nevertheless for the de Gaulle:
    - 42.500 tonnes full displacement against 44.000 of the Russian design. But the later has a WAY bigger flight deck.
    - Max 40 aircraft against 46. Remind, those Rafales are in fact lighter than the MiG-29K. 2 AWACS against 4. And 3 helos against 12-14.

    so far Su-57 was only in 3 plastic models on Shtorm (by Krylov BTW lol1 lol1 lol1 ). I just wonder how those Su-33 on ake off position is going to start without ski-jump neither with a catapult?!
    Don't know what is so funny. At the risk of disclosing a big secret, Krylov designs vessels, not planes. And besides, this is no official MoD project so the confirmation value the represented planes have is essentially zero.

    Regarding the Su-33, what take off position are you referring? The ones I see are equipped with a pretty big ski jump

    George1 wrote:and it is in the same class as Kuznetsov
    Yes, in regards of flight deck and amount of planes. But K is 50% heavier. This is the great advance caused by the semi-catamaran design, allowing a wider hull for bigger internal space and huge flight deck with smaller displacement

    Yes.
    I even pointed out pics showing the catamaran stern & even earlier highlighted that the specs given are wider than a Nimitz.

    Problem I have is that semi-catamaran style has been tried unsuccessfully in reality several times & were very much failures

    The Su planes on that model are not Su-33s, they're actually Su-30 style two-seaters which is why I've been talking up a navalised Su-30.

    Entirely possible they just couldn't get hold of Su-33 kits of course Suspect
    But seems it'd be a fairly cheap/quick way of getting newer more capable airframes.

    “Technology of stealth does not make sense. No one will look for you with the help of radar - except for those who are sitting on the ground. And so they will cope with stealth. There is no stealth for large ground radars,”..

    Experience in real war over the last few decades show that large ground radars are the first systems taken down in an attack/invasion.

    The fact that a big ground based radar can detect your stealth aircraft does not mean your interceptors you send up can find them... communications will likely be jammed and the source of your commands from your main radars to your pilots will also be noted.

    The first things your cruise missiles destroy will be those comms centres, HQs, airfields of course, and major Radar installations and of course known SAM sites.

    Once they have been degraded then control of the air becomes much easier.

    For an enemy to detect you they must use their radar which creates data for you to add to your targets database.

    Obviously with an enemy with no C4IR and no IADS then you take it down piece by piece... instead of white playing black it is white playing individual black pieces all operating on their own in the dark because their comms are jammed.

    With Russian carriers having stealthy Su-57s is useful because in addition to being stealthy they will also be very very capable fighters.

    Having a real AWACS platform instead of an AEW like a Ka-31 means the AWACS platform in the air will probably be detected, though with modern AESA radar it could still operate in a low emission mode that makes it hard to find.

    The point is that it will be relatively easy to spot, but it will also see you coming from a long way away and so it can send commands to aircraft in the air and ships on the surface... this will again betray its position, but the aircraft and ships don't generally need to reply so you don't know where they are or how many there are... your rush to attack and shoot down that AWACS you detected 1,500km off your coast might lead you to fly over a cruiser with more firepower than 20 S-400 batteries plus 2 S-500 batteries, and of course the equivalent of 30 S-350 batteries and a dozen Pantsir and TOR batteries... OOPS.

    And being a C4IR system they wont need to turn on anything.... just use data from the AWACS to get their ARH S-400s within a few kms of your planes and their ARH seekers will do the rest...

    1) to fully test Su-57 phase II
    2) to wait until fighter is fully tested, with full spectrum of weapons and there is a really need (so far Su-35 is enough for all threats)
    3) thus save resources now by postponing full production for other projects

    They already have Su-35 and MiG-35s ready to enter service and from what I have read they are rather cheap in comparison to stealthy aircraft and would likely have lower maintenance and operational costs too... what is the rush to get the Su-57 into service?

    With new technologies stealth might turn out to be not the game changer the supporters keep saying it is... I mean why is Israel so afraid of the S-300 system first developed from the late 1960s... the F-35 is supposed to be able to penetrate S-400 systems and win...

    Well as for mini and limo good example. Do you know why limo is expensive? because is available to few. Most people drive Hyundai or Honda to have reliable and affordable car.

    The problem is that in this example the mini is spruced up to be like the limo, which makes it no longer affordable.

    Lets be honest.... when the Harrier first came out it was going to be the best plane ever because it could still take off and land when all the airfields were destroyed... it meant you could have very small... practically helicopter carriers and save a lot of money.

    The problem was that it was all a lie.

    Harrier cannot take off from any old strip of open ground... it just can't... and those little helicopter carriers can only use helicopter based AEW... which is certainly better than nothing of course... but a real carrier with real AWACS platforms and real fighters would have been vastly more use to them in the Falklands Islands war.

    I didnt find much about it, would be appreciate to learn more about it. Then what and when was changed comparing to 80s ?MiG-29M frame?

    The MiG-29M which didn't ever enter service from the mid 1980s was based on 1980s technology but even it was different from standard MiG-29s.

    The MiG-29M used wielded construction so internal spaces could be sealed and plumbed and used as fuel tanks. The skin of the aircraft became part of the structure.

    The Indian order reopened production but production of the new aircraft design with all new materials including composites. The design was revised to be more stealthy and used up to date components and systems. There was still a delay between production for the aircraft for India and the aircraft for Russia because pretty much all the foreign components in the Indian version were replaced with new Russian equipment.

    The new design is a two seat configuration and when used as a single seater extra fuel is located in the place where the second seat would be... something they didn't do with the MiG-29 and MiG-29UB which were different.

    Would you answer my already couple of times asked question: why all countries prefer to build new fighters if upgrading old is so fine idea?

    Name one aircraft in service right now that is not an upgrade?

    Even F-35s entering service are not block 1 models they have been improved or modified... and it is the same for all other aircraft in Air Force service everywhere... they are up to block 70 updates for the F-16s flying around the place... in fact it looks like the full entry into mass produced service for the Su-57 might be waiting for the new engines and some other technologies to mature and become available...

    VSTOL is more complex but not "fragile" that's your phobia not reality. 6g fighter is same level of complexity complexity and "fragility" . Yet both Russia & US are developing them.

    We don't even know what constitutes a 6th gen fighter, but we can be sure it will have backup systems and redundancies so that in the case of a failure that it can limp home. A VSTOL with a failed engine or even a blocked nozzle is screwed.... even shrapnel damage could render the aircraft unable to hover... which means it needs a backup alternative... hook and cable system... so it might as well get rid of the V and just use STOBAR instead and become a much simpler and cheaper aircraft with better performance.

    To argue STOVL can be cheap and effective is like trying to argue the Ka-52K could replace STOBAR fighter planes in a much smaller and cheaper airframe...

    Some solid rocket boosters could extend the range of standard AAMs and its AESA radar array could be enormous... look at the size of the aircrafts nose...

    3 times I've already asked - 0 links with source provided by you. So we stop this ad nauseam mantra here.

    Asked what?

    stop repeating ad nauseam same mantra, will ya? nobody is going to do continuous VTOL on unprepared locations. VTOL is required by navy mostly. Space on ships is scarce.

    Who said anything about continuous.... it can't even take off once vertically without heat resistant matts protecting the ground...

    BTW how do you think Su-57 can start so short for it weight if not using of TV?

    Large wing area for its weight and the ski jump directing the aircraft into the air at launch at which point the engine nozzles would be deflected at a downwards angle to contribute both forward thrust and lift to unload the wing and increase their capacity to generate lift.

    1987 was approved plan for low rate initial production in Saratov plant 292.

    There were only two flying prototypes and after one crashed the program was cut.

    The reason for the crash was obvious exhaust thrust hot air ingestion in the main air intake... solution would need a complete redesign to stop the hot gas from the lifting engines moving forward near the main engine intakes.... a much better solution would be some sort of engine driven lift fan but it would still seriously compromise the design because you have this enormous bulky lift fan that is not that heavy but of no use in normal forward flight and take up an enormous internal volume of space that can't really be used for anything else like fuel or electronics.

    It is this enormous internal volume that makes the F-35 a bit of a dog... if it didn't have that design requirement it could be a stealthy F-16 which is what it was originally intended to be...

    MiG-29k appeared only because of Indians not because it was so great fighter.

    Even if the Yak-41 design had been available they would have picked the MiG... it simply has better performance, is simpler and cheaper to buy and to operate and has a lot of commonality with a plane they also operate in their air force. Normally not an issue but sometimes you can share spares pools in critical situations. The Yak-41 would still be a technology demonstrator with flaws and bugs that wont come cheap to fix.

    PAK FA after after almost 20 years of development was rejected by one main cosponsors. Poor stealth,no new engines, not really better than other new fighters but very expensive. One of prototypes failed and burned because of engine malfunction. Thats why 20 years after start programme RuAF ordered 12 units.

    Yeah... you actually have to contribute funds to something to be called a cosponsor, but poor stealth compared to what... does India have an alternative choice of their own? Its current engines are more powerful than the engines on the Su-35 and it is smaller and lighter than that aircraft... and the Russian AF says the Su-35 is good enough to make the Su-57 not so urgent that it has to be rushed into production and service. Of course it is more expensive... it is not called next generation for nothing.

    If India thinks it is crap why isn't it ordering F-35s?

    Why has it actually said it would wait for the aircraft to get into service and then look at it again.

    Would they have said the same things about the Su-30M before they bought it and put it in production?


    and same guy said that MiG-41 will be produced as from 2025th, didnt he?

    Have heard MiG guys and AF guys say the MIG-31 will need replacing by 2028, so if they don't have something ready to replace it by 2025 their might be issues.

    Navalized fighter weights 500-700 more. Then did he tell potential customers that this is already navalized and heavier fighter or he was just bullshiting potential customers? like they have no experts on their own.

    Having a stronger aircraft is not a bad thing... naval models of the MiG-29 also had more powerful engines and larger wing areas than the land based models too...


    yeah in 70s-80s data transmission was suspicious indeed. Not in 2030s tho. You see AEW&C can be realized in many ways, IMHO chopper is worse than drone. Both ceiling and duration fo flight makes drone a better option.

    Yeah actually I don't know... the Kamov is a very heavy helo, but a real fundamental change from the ground up to make it an AEW platform could probably make a real difference in terms of weight and size... I mean even putting the new more powerful engines Klimov have developed should add to performance in terms of operating height and a serious upgrade in terms of electronics could also transform its performance... but even assuming it remains in the 10-12 ton class... what sort of UAV do you have in mind in that weight class than can carry a 6 metre wide antenna array and also spin it in flight.

    I mean it is all nice a fixed wing UAV able to fly faster and higher than a AEW helo, but if it can't deploy a radar antenna as big and can't maintain height with such an antenna deployed then you gotta say how is this thing going to operate... it will need serious engine power to get airborne from the Kuznetsov... whereas the Ka-31 could operate from a frigate and jump from frigate to frigate or destroyer even without a carrier present... it could even operate from a supply ship that is supporting the surface group... most of them have helicopter pads...

    They actually do. UAV Fregat already has working proof of concept. VDV requested own tiltrotor (perhaps will be competing with high speed helo).
    Long before any CV is gonna be launched tilltrotor can be reality.


    Ahhh dude... if a small model that takes off conventionally constitutes proof they have a tiltrotor, then can I refer you to various plastic models and fan art to prove they have 70K ton carriers too?

    This would explain the big divergence between the size of a conventional flight deck and the one of the new light carrier proposal. Very good and deserving of credit to innovate in CV configuration after some many decades of rather unchanged designs

    Very clever and very promising... thinking outside the square... but odd designs will be a hard sell to the Russian Navy... they are quite conservative.

    Lets face it one of the reasons they went for the Mistral was that the design was proven and could in theory (and in fact) be built rather quickly and put into service rather fast too... well except for the fact that the French are censored .

    Su-57 can take off in very little space because, even fully loaded, will have a T/W ratio really close to one (that means, it could almost take off vertically like a rocket) and will be further helped by a ski jump. This considering izd. 30 engines will be in line with claimed thrust of course. It will accelerate horizontally and the rotation will be done with help of the ramp. Don't really think TVC + LEVCONS can create lift through deflection which is more useful than the pure acceleration of the engines in the horizontal plane.

    Everything takes off easier with forward motion.... VSTOL, Helos, and normal aircraft...

    You forgot to say that you need really high speed to get lift what is impossible to have in short take off without TV.

    Rubbish... all you need is an increased angle of attack... provided by a skijump for an Su-57, but it also has TVC so it can control its wings angle of attack anyway.

    An AN-2 can't fly at really high speed, but would be able to take off from the Kuz...

    True but 44ktons, not nuclear pp what in Russias case sucks with scarcity of bases and nuclear powered liders? Full size air wing? 24-28 fighters from which 12 light migs?

    Scale it up to slightly bigger than Kuznestov and give it nuclear propulsion and EMALS and a ski jump ramp and they might have something there... very clever... offers some advantages of a catamaran design without the excessive width issues...

    Shallow draft might be an issue in terms of internal space but then an all nuclear electric drive where nuclear power generation can be placed as ballast to generate electricity with electric pods at the front and back like on their new icebreakers so it wont even need tug support in dock...

    I see only Su-33 and MiG-29K, not even navalized PAK-FA

    Not their job to speculate on what aircraft might be used... using current aircraft suggests it could go into service now without the extra cost of developing new aircraft for it...

    I just wonder how those Su-33 on ake off position is going to start without ski-jump neither with a catapult?!

    It has a ski jump...

    Not really. You are using cheap propaganda arguments which make no sense at all. Garry was trying to point out fundamental conceptual flaws (ingestion of hot air) that motivated to change to a lifting fan in the F-35. He is openly critic of STOVL but that does not mean he is using empty arguments

    I remember the 1980s when Harriers were the thing... especially after their performance in the Falklands War.... but as information trickled out it turns out that it was more pilots skill and new missiles that made a difference... not to mention all the promises about operating from open clearings in fields or supermarket carparks was all rubbish.

    Before it was revealed that they were using new missiles there was even a suggestion they used vectored thrust to outmanouver the Argentine pilots... in fact they had a name for it... VIFFing... vectoring in forward flight... of course a load of rubbish...

    Again your words far of the real information, because do not resist the contrast with.

    The ship presented in the Forum Army 2018 is to export. And logically is presented with conventional propulsion.

    Logically Russia does not export nuclear reactors for military purposes.

    Taking into account that the Russian Navy rejected projects under 70000 tons, not sure if we will see the variant with nuclear propulsion.

    I assume this idea was intensively tested (at TsAGI probably?) before they disclosed it... I think this is a great approach, this size of deck for 44 kT is really surprising. Nuclear propulsion and little bigger (for bigger endurance and hopefully one fighter squadron more) and they would reach practical parity with USN carriers. Counting on Su-57K maybe even this size would work Very Happy

    I'm sure that Shtomrm was also intensively tested tha same way lol1 lol1 lol1 This concept IMHO is just kind of CGI only in plastic. That's the problem. Surely 12 Su-57 oh well 18 would make it equal to 90 fighter US Ford Suspect Suspect Suspect especially with FA-XX

    It is better if you make some numbers, really. How fast do you think a Su-57 would travel after 100 m take-off run accelerating @ ca. 1g? It is not slow at all,

    Assuming constant a=9,8m/s2
    I assumed take off speed 180km/h = 50 m/s
    it would be

    in fact it is enough for naval planes to go well past stall speed, especially when using a ski jump. You can watch videos and check your numbers easily. A fighter like MiG-29K covers this distance in the K in little over 5 seconds IIRC, starting from standstill. That is, by the end of the ramp it is close to 180 km/h, plus the wind + ship speed. So it takes off easily...

    Then VSTOL needs even less. Yak-141 w/o skijump (with deck arreststers to get full trust) 70-80m.  OF course 80m of ship is for free.  Soruce Yefim Gordon Russian
    Yakovlev Yak-38 & Yak 41-M: The Soviet Jump Jets )

    True that VSTOL are more complicated but offer other qualities. Especially needed for Navy. Ingesting of hot air like PAK-FA which fell and burned means design needs to be reworked or fighter is to be dropped? Garry has full right to express his opinion what doesnet change the fact that VSTOL program was officially started.




    x



    Nevertheless for the de Gaulle:
    - 42.500 tonnes full displacement against 44.000 of the Russian design. But the later has a WAY bigger flight deck.
    - Max 40 aircraft against 46. Remind, those Rafales are in fact lighter than the MiG-29K. 2 AWACS against 4. And 3 helos against 12-14.

    OK so you admit that smaller fighters and small displacement count.  yes sir  yes sir  yes sir    

    As for Krylov vision:

    1) We should alwasy compare 30years old design with new one to increase feel good factor
    1) hull was extensively tested  ? ekhm any proof of that? I'very much doubt on this
    3) AEW? they didnt mention AWACS in brochure. And of course platform  which no programme was even vaguely announced? ?
    4) narrow hull large deck high deck. I'm sure this helps with buoyancy

    5) 24-28 fighters doesnt sound like numbers you wanted to see...



    Don't know what is so funny. At the risk of disclosing a big secret, Krylov + value the represented planes have is essentially zero.

    The secret ingredient?  lol1  lol1  lol1




    Regarding the Su-33, what take off position are you referring? The ones I see are equipped with a pretty big ski jump
    then look again and it those shall use skijump then needs to turn sharp righ to start  thumbsup  thumbsup  thumbsup

    The problem is that in this example the mini is spruced up to be like the limo, which makes it no longer affordable.
    it was your example you just love expansive toys, unlike Russian Navy which probably prefer Honda (on of least trouble prone cars) and still affordable.



    Lets be honest.... but a real carrier with real AWACS platforms and real fighters would have been vastly more use to them in the Falklands Islands war.

    and which one from "proper" British carriers would you use then? BTW Again mantra about 80s?!





    The Indian order reopened production but production of the new aircraft design with all new materials including composites. The design was revised to be more stealthy and used up to date components and systems
    +++
    and it is the same for all other aircraft in Air Force service everywhere... they are up to block 70 updates for the F-16s flying around the place...

    .
    ok so basically frame form 80s was redesigned on early 2000s and should fly well in times when 6gn is supposed to fly? Is that what you suggest for Russian Navy? and In US F-16 or F-18?





    VSTOL is more complex but not "fragile" that's your phobia not reality. 6g fighter is  same level of complexity complexity and "fragility" . Yet both Russia & US are developing them.

    We don't even know what constitutes a 6th gen fighter, but we can be sure it will have backup systems and redundancies so that in the case of a failure that it can limp home. A VSTOL with a failed engine or even a blocked nozzle is screwed.... even shrapnel damage could render the aircraft unable to hover... which means it needs a backup alternative... hook and cable system... so it might as well get rid of the V and just use STOBAR instead and become a much simpler and cheaper aircraft with better performance.

    1) if there are damaged nozzles in Su-57 or Su-35 both fly normally. Only VSTOL has problems.
    2) Russians spending money on VSTOL project without considering cost benefit

    Let's agree to disagree. VSTOL is no less "fragile as any other fighter. Complexity is balanced by smaller and cheaper ship to carry or more of fighters on deck. And no Russians are no idiots.



    Who said anything about continuous.... it can't even take off once vertically without heat resistant matts protecting the ground...

    and making full airbase with 2km concrete runways is faster, easier and cheaper then truckload of such matts?




    BTW how do you think Su-57 can start so short for it weight if not  using of TV?

    Large wing area for its weight and the ski jump directing the aircraft into the air at launch at which point the engine nozzles would be deflected at a downwards angle to contribute both forward thrust and lift to unload the wing and increase their capacity to generate lift. [/quote]

    Well TVC was actually developed for STOL or V/STOL. F-15 TVC was designed to be STOL fighter. To have shorter runway . Sameas Russian fighters. So as long as I seriously doubt that TVC is not used during STOL. Of course wing surface helps. But who says VSTOL cannot have large wing surfaces, canrds or LREX?






    1987 was approved plan for low rate initial production in Saratov plant 292.
    There were only two flying prototypes and after one crashed the program was cut. [/quote]

    Actually there were 4 41 and in Saratov ordered 8 prototypes of Yak 41M (improved avionics + LREX)



    The reason for the crash was obvious exhaust thrust hot air ingestion in the main air intake... solution would need a complete redesign to stop the hot gas from the lifting engines moving forward near the main engine intakes....

    I agree but
    1) improvement agains existing VTOLs was a quantum leap
    2) Yak was continuously improving design thats why 8 pieces was already 41M

    It is this enormous internal volume that makes the F-35 a bit of a dog... if it didn't have that design requirement it could be a stealthy F-16 which is what it was originally intended to be...

    My idea about Russian VSTOL, less weight on stealth or bomb payload, more on being a maneuverable fighter with efficient engine.



    Even if the Yak-41 design had been available they would have picked the MiG...
    that we dont konw.




    Yeah... you actually have to contribute funds to something to be called a cosponsor,
    If India thinks it is crap why isn't it ordering F-35s?

    because they didnt sponsor that lol1 lol1 lol1 and seriously I added this paragraph to show absurdity of accusations that Yak was shit. You can cut press releasees and try to prove similar thing to very capable fighter.




    Have heard MiG guys and AF guys say the MIG-31 will need replacing by 2028, so if they don't have something ready to replace it by 2025 their might be issues.

    Then they need to find workaround. Quick.

    Still radar horizon depends on ceiling... with 3km you dont have more than 250km for surface targets. Ka-60 in turn has 6km...but only 2500kg payload.

    Scale it up to slightly bigger than Kuznestov and give it nuclear propulsion and EMALS and a ski jump ramp and they might have something there... very clever... offers some advantages of a catamaran design without the excessive width issues...

    why to stop on Kuz size? if you have unlimited budget scale at will. If not below 40ktons.



    I just wonder how those Su-33 on ake off position is going to start without ski-jump neither with a catapult?!
    It has a ski jump...

    but not on left runway looking from front. But ok that Su-33 is so good that can sharply turn right before start and use ski jump Twisted Evil Twisted Evil Twisted Evil

    @Gunship:

    You keep stretching data and arguments so much I don't know what to say.

    From the data shown you see simple STOBAR fighters take off with more load in less space that STOVL ones... and besides that they have more useful capacity since they don't need additional lift-generating HW and are cheaper and simpler.

    Therefore, only clear theoretical advantage of STOVL is in landing, but arresting gear has been used for decades and also STOVL end up performing rolling landings so in the praxis they are only sensible in very small and basic LHDs. If you have CVs, logic indicates to put a ski jump on it, arresting gear and a catapult in the angled deck.

    STOVL program has been apparently started, we will see what the result is in terms of both aircraft and carrying vessels. By now the only reality in RuN is the K with its Su-33 and MiG-29K, and it will continue to be so for a good while

    and besides that they have more useful capacity since they don't need additional lift-generating HW and are cheaper and simpler.

    So you are serious? deck fighters are much more complicated and heavy than land based. Gear, frame must  stronger, hooks, anti corrosion not to mention. Only 2 richest fleets in the world : US and China are manufacturing and designing those.  This is the best proof that they are both simple and cheap. Now compare navy doctrines and budget of USN and ChN with RuN.  

    ah yeas France too!  Rafale is cheaper than VSTOL. Needs catapult and  programme cost is 45blns€ . That's why is cheap!  lol1  lol1  lol1






    Therefore, only clear theoretical advantage of STOVL

    If this would be correct (what is not IMHO) than is good enough since besides USN and Chinese Navy  all other navies with deck fighters either have or design/plan to develop ones. But this is only in your theory so far.



    is in landing, but arresting gear has been used for decades and also STOVL end up performing rolling landings so in the praxis they are only sensible in very small and basic LHDs. If you have CVs, logic indicates to put a ski jump on it, arresting gear and a catapult in the angled deck.


    Very small like 70ktons QE2? As for size. do  you live in the world of endless military budgets. Lucky you, RuN does not.  TVC and skijump were designed for deck fighters and applied for VSTOL first. I see no problem with using VSTOL with both but this is no argument against . Just VSTOL use those facilities more efficient.

    BTW Project Yak-43 was to be STOL only. Land based. Its takeoff strip was to be 130m without ski jump.  Vs MiG-29k 240m. Payload: 4000kg vs 4500kg. Of course navalized is better scratch scratch scratch[/quote]

Design bureaus do not engage in such reputation-destroying activities normally.

    Of course! this was precisely what they said. Both fighters will fly ~10 years and when they already obsolete technically and morally are gonna be retired.
    BTW if apparently here - is defined as  an official announcement of deputy PM for MiC mentioning direct Supreme Commander  order then yes. thumbsup thumbsup thumbsup
    Good that we agree on something.
    I consider it firm when contracts are disclosed, until then I take it as an intention to develop or work on something. Only being cautious, not denying anything.

    from which data? can you provide hose?  
    Less space?!  precisely which one vs which one  like Su-33 vs F-35?
    I (and others like hoom) have shown the Su-33 and MiG-29 can take off almost 100% load from the short positions on the K which are 95 m. In sharp contrast, the F-35B needs 600 feet to take off full load, which is almost DOUBLE the space. And that considering the neglected Su-33 and MiG-29K with 4G engines, while the F-35B has the BY FAR highest T/W ratio and most modern fighter engine in the world and is a brand new 5G design. To talk about fair comparisons...

    As for payload is only in your fantasy. Check numbers please  before you say something like that again please. Numbers say:

    Su-33....................6,500 kg (in air superiority variant 3,300kg)
    Mig-29K.................4,500 kg
    F-35......................6,803 kg
    Have you considered fuel? And maybe cannon which F-35B does not even carry? I dived deep in these data and brought them to you on a silver plate, but you manage to ignore them one way or another. Short T/O performance of F-35B sucks compared to a high T/W ratio STOBAR fighter. It is that simple.

    So you are serious?
    100%. You just have to compare the F-35A and B to see prime example of capacity impairment due to STOVL. And it is huge.

    deck fighters are much more complicated and heavy than land based. Gear, frame must  stronger, hooks, anti corrosion not to mention.
    I a not talking about naval vs land based but STOBAR vs STOVL.
    STOVL for naval use must meet almost all the requirements that you mention above plus huge amount of HW for generating and controlling twenty tones of vertical lift, which in our universe translates invariably into weight + space + cost + complexity. Given the scarcity of space and weight restrictions of a fighter, it is a huge design compromise.

    Only 2 richest fleets in the world : US and China are manufacturing and designing those.  This is the best proof that they are both simple and cheap. Now compare navy doctrines and budget of USN and ChN with RuN.  
    Manufacturing what? STOBAR? CATOBAR? Naval fighters in general? RuN does operate naval fighters in STOBAR configuration so they probably match their doctrine  thumbsup

    ah yeas France too!  Rafale is cheaper than VSTOL. Needs catapult and  programme cost is 45blns€ . That's why is cheap!  lol1  lol1  lol1
    What 45 billion? They use steam catapults licensed from US, but nevertheless I don't understand what you try to proof.

    Very small like 70ktons QE2? As for size. do  you live in the world of endless military budgets. Lucky you, RuN does not.  TVC and skijump were designed for deck fighters and applied for VSTOL first. I see no problem with using VSTOL with both but this is no argument against .

    Look, Russia has STOBAR CV and fighters, don't tell me they can't afford them.

    Future Russian Aircraft Carriers and Deck Aviation. #3 - Page 6 Empty New concept of semi-catamaran aircraft carrier for Russian Navy.

    Post  Ives on Fri Oct 05, 2018 9:36 am

    Krylov institute presented a concept of semi-catamaran carrier: https://tass.ru/armiya-i-opk/5625190

    The authors claim, that despite of being light(44k tonnes), it would be able to carry the same amount of aircraft units as a medium weight carrier, thanks to it's semi-catamaran desing. So, what do you guys think?

    OK and for me it is like car manufacturers dont first design car then will never ever be on streets just to see what people say? You can suppose whatever you want but as we both know there is no proof Krylov did anything like that.  And unlikely as this requires both time and money.




    > I have hoped for Su-57K and also given my personal opinion, based on objective design features and Flanker precedent, that the plane has the potential to be modified for naval operation.

    OK fair enough. We both exchanging here personal opinions. . As for Su-57 there is no such thing as deterrence with 20-24 fighters  against couple of US CSGs with 150-180 and large escort groupings. Any blockade  of Russia is a declaration of war.  Price? 100mlns $ is a piece (source wiki) so mildly estimating navaized is 150mlns$ .

    large CVN  14 bln $,  if you have 40 Su-57 there +6billions = 20blns  + escord group  (numners based on similar ships build in the west)
    Small CVN  (lets say 2,4-3) + 3,6$ blns for 24 fighters so you got  6blns +escort group

    If is unlikely to be cheap and disputable qualities of deterrence. And in country which builds 22800 instead of frigates. because you got small ship 200mlns cheaper.

    As for other tasks   Syria type war we know no PAK-FA was ever needed. Since 2015.





    I consider it firm when contracts are disclosed, until then I take it as an intention to develop or work on something. Only being cautious, not denying anything.

    You can consider as you like, sir. The fact is: deputy PM for MiC Borisov said it is included in new SAP 2027 and Putin personally asked to start it. I am sure this is not firm. Cool calculating Putin just loves expensive new toys. . Unlikely any contract is going to be sighed until fighter is ready.

    BTW What precisely contracts were signed since 2000 till 2018 for  PAK-FA? none. in 2018 12 pieces? and MiG-35 - first flight 2007 - 2018 none. In 2018 whooping 6 pieces ordered.  

    You can consider it firm. 12+6





    I (and others like hoom) have shown the Su-33 and MiG-29 can take off almost 100% load from the short positions on the K which are 95 m.

    and what is "almost" 100% with what fuel/range then? In AA profile Su-33 takes 3300kg . Dunno why.




    In sharp contrast, the F-35B needs 600 feet to take off full load, which is almost DOUBLE the space.
    and? how does it relate to new Russian fighters? what does it prove? absolutely nothing. We dont know what will be specifications of Russian fighter.

    ha ha If you almost double form 4 to 7 tons MiG payload then perhaps we can make any.
    BTW Obsolete Yak-41 could start 120m. Without skijump. With could perhaps 40-50m.







    Short T/O performance of F-35B sucks compared to a high T/W ratio STOBAR fighter. It is that simple.
    you never compared Su/MiG starting without Ski-jump, why? F-35 starts 2/3 at worst this distance and there is nothing preventing it using ski jump. Nothing.







    So you are serious?
    100%. You just have to compare the F-35A and B to see prime example of capacity impairment due to STOVL. And it is huge.[/quote]

    Huge in precisely what? in range? 300km? in payload? (6,8 vs 8tons)? what here is huge? Combat radius of F-35 is still better then MiG-29K (935 vs 850km)

    BTW: F-35A is land based
    F-35B is naval VSTOL






    STOVL for naval use must meet almost all the requirements that you mention above plus huge amount of HW for generating and controlling twenty tones of vertical lift, which in our universe translates invariably into weight + space + cost + complexity. Given the scarcity of space and weight restrictions of a fighter, it is a huge design compromise.

    Building a jet fighter is already compromise since turboprop has better range and fuel economy. Once you decide to sacrifice economy for  speed, simple canards make a fighter structurally unstable and without advanced computer algorithm cannot fly Is it not a compromise? navalized fighter is  again compromise.  Weight, range and payload vs short take off is already a compromise.

    That's why you got technology for.




    Manufacturing what? STOBAR? CATOBAR? Naval fighters in general? RuN does operate naval fighters in STOBAR configuration so they probably match their doctrine  thumbsup


    and now started VSTOL as it suits much better  russia  russia  russia BTW what contradiction do you see between CATOBAR and VSTOL?




    ah yeas France too!  Rafale is cheaper than VSTOL. Needs catapult and  programme cost is 45blns€ . That's why is cheap!  lol1  lol1  lol1
    What 45 billion? They use steam catapults licensed from US, but nevertheless I don't understand what you try to proof.

    No not steam catapults but Rafale.  After wiki: Rafale
    Program cost €45.9 billion (as of FY2013)[9] (US$62.7 billion)




    Very small like 70ktons QE2? As for size. do  you live in the world of endless military budgets. Lucky you, RuN does not.  TVC and skijump were designed for deck fighters and applied for VSTOL first. I see no problem with using VSTOL with both but this is no argument against . Just VSTOL use those facilities more efficient.

    Look, Russia has STOBAR CV and fighters, don't tell me they can't afford them.[/quote]

    Tell it to Russians.  They have decided to build VSTOL instead going down your route. In ~10 years they will  have no STOBAR anymore. As soon as VSTOL is in series.
