    Not for long before having maintenance & safety issues. Steam will add moisture on the flight deck leading to ice buildup.

    I would assume so. I don't know how they are going to manage ice build up on critical areas. Perhaps they will need to add a lot of electrical heaters in exposed areas but how effective will it be!

    I would assume so. Don't know how they manage to to prevent ice build up in critical places when the temperature outside is -40 C. Perhaps they will need to add a lot of electrical heaters in exposed areas but don't know how practical that is going to be.

    With a nuclear reactor that shouldn't be difficult to solve. They have operated Kuznetsov and kiev class ships in the north and the ice was never an issue.

    US operates its carriers in the atlantic where temperatures are also low and don't have this issue.

    The Barents Sea is warmer than the rest of the Arctic; East of it there's nothing for the CVN to do, unless it transits to/from the Pacific under an icebreaker escort & with its planes either parked or flown cross country.

    And ? There will be a maintenance crew for the catapults that will clean and repair them. The system can be isolated from outsude cold weather.

    It it were me, i would restart the Yak-44 project, with modern radars and electronics of course. For the engine, as I wrote already in another thread, instead of the D27 from zaporozhe (the same engine that should have gone to the An-70), they could use a turboprop/propfan derivative of the PD-12V engine (a turboshaft derivative of the PD14, that should replace the Ukrainian engine on the Mi-26 helicopter). I do not know about the status of the PD-12V engine, but once that is ready a turboprop/propfan derivative should not take too much. I believe that there is enough competence to produce a modern aircraft gearbox for such engine. The propellers were already  made from the Russian company Aerosila,  so no problems there.



    Thats to me most intriguing part. Ka-31 is the cheapest but functionally the worst option for AWACS. Lower ceiling then E-2 10,500m vs 3,500m for Ka-31. Mission time 2,5hrs for both but E-2 can be refueled and fly 5 hours on mission.



    Investing in (never finished) Yak-44 is like restart the 50 years old design. The new platform for 2030s? US BTW USN has just started replacing own Grumman C-2 Greyhound with tiltrotors. Which do not require any catapult. C-2 is same airframe as Grumman E-2 Hawkeye AWACS.

    No I mean after recieving  the techical specifications from the customer (the Russian Navy) they will work on improving the preliminary design based on a modernized ulyanovsk (possibly for a couple of years) and then, after that is approved and goes to the stage of detailed design it will take probably another 2/3 years until they can pass the critical design review and start cutting metal. I am not a naval engineer though, so i do not know if there are differences in this sector compared with other industries.

    Mig-35 is a modern 4++ platform and from what i understand it has some commonality  with the mig29k that make the realisation of a carrier version quite easy.

    In addition, it is probable that India will order a bunch of them for their new carrier and Russia could order a small squadron as well to be used for ground training and in Kuznetov, supplementing the 23 mig29k that they already have.

    For sure it is not worst than rafale and it is much better than the f/a18 in service with the US Navy.

    Anyway i only spoke about that since our serbian friend mentioned that no carrier aircraft existed.


    P.S. how do you know that no Su-57K will be developed?
    The new carrier will not start trials (in the best case) before 2030. There is plenty of time for it.

    The basic concepts and aerodynamics laws do not change. They do not need a stealthy supersonic awacs, or transport  aircraft. They need an aircrafts with good loitering capability,  sufficent range and payload, and possibly better ceiling and speed compared to what is currently available. A turboprop/ propfan aircraft is better for this, and has better performances than a tiltrotor.

    What is making the difference is all the radars and electronics, but of course you need a platform (an airplane) that can carry the radars and have them operative for a long enough time.

    Yak-44 could be just the starting point of the design of the new carrier based awacs, just as the Let-610 design will be used as a baseline for a passenger/transport aircraft for regional applications (in a category between the Let-410 and the il‐114).

    In addition the Yak-44 derivative will also have modern engines and avionics, and will exceed the Osprey based tiltrotor in every  parameter except vertical takeoff and landing (that are not needed since will use catapults and arresting cables)

    Anyways there would be no point  in developing catapults and building a 75000tons carrier if you only plan to use tiltrotors, helicopters and stovl aircrafts.

    if Russians go for catapults there will be much more sense in investing into EM catapult. Less mechanically complex, reduced crew requirements and more starts per minute. No problems with icing of condensed steam .

    it is upgraded 80s design in plain words. It is a good stopgap but it doesn't really looking like a perspective fighter to counter US/NATO 6th gen fighters. For Kuz it woulds make sense as Kuz is back soon. OK relatively soon in line.

    BTW why Rafale should be better then F-18 ? less payload, power and worse avionics? just curious.

    I dont but about carrier there were a lot of discussions in Russian media sphere since 2014. But nothing wrt to Su-57k really. Only 2-3 times mentioned VSTOL development since 2017 (AFAIR)

    Im not claiming Im right, it is just my point of view.

    1) E-2 doesn't exceed V-22 naval version in anything except service ceiling AFAIK.

    2) And US will use E-2 till the 2030s when next gen will appear. V-22 is replacing C-2 for a reason. USN has 90-100ktons CVNs with catapults yet replaces C-2 with V.22. There must be advantage I guess.


    3) UK from the other hand has 2 70k CVs without catapults and VSTOL ;-)


    So the future " is great wide open" (c) Tom Petty


    But the point here is: that there is a substantial difference between USN and RuN. USN has E-2 since 70s. Their life will be extended till 30s but it is already legacy tech. And if RuN is going to use upgraded 80s designs (MiG-35, Yak-44) then they will invest into yesterday's tech vs US tomorrow's tech.

    Ka-31 is the cheapest but functionally the worst option for AWACS.  Lower ceiling then E-2 10,500m vs 3,500m for Ka-31.
    They could adopt the Mi-38 with ~2x Ka-31 ceiling (6,500 m) & range:
    https://en.wikipedia.org/wiki/Mil_Mi-38#Specifications_(Mi-38)
    https://en.wikipedia.org/wiki/Kamov_Ka-31#Specifications_(Ka-31)

    If the future CVNs will have escorts armed with naval S-400/500, their radars+UAVs will be enough to cover any gaps created by the absence of an E-2 counterpart.
    Also, they could deploy IL-38s/Tu-214/A-50/100s to bases in Cuba, Nicaragua, Venezuela, Syria, Libya, Algeria, Iran, India, Pakistan, Sri Lanka, Myanmar, China, Philippines, Vietnam, Sudan, S. Africa, Mozambique, Angola, & Argentina to cover all of the possible areas they'll sail into.

    which are NATO 6th generation (naval) fighters?

    There is the plan for the uk tempest and for a German French fighter, but nothing is clear about them and they are at least 15 years away.

    And anyway by that time Russia could further modernise their su57.

    So until at least 2035 i do not see any naval fighter that could be so better than a mig35K, and after that a su57k, maybe with a mid life improvement would be able to be at least on par with NATO so caller 6th gen fighters (that would not have reached yet full operational capability,  by the way).

    It is also possible that half of the carrier air wing will be composed by unmanned aircrafts btw... we will see.

    Concerning the Russian STOVL naval fighter, we will see. They announced that they are working on it, but I  do not believe they want to put all of their eggs in this basket.
    For them the best would be if some country with more money (to waste) than sense (e.g. some of the arabs countries) would fund most of the development costs. At the end it would be still cheaper for such customer than buy overpriced American products (yes I know that the military spending for those countries is also a out of jail card that allow them to kill people in embassies and live like a middleage dictatorship but have better PR than most countries, however they are already diversifying their expenses and looking with interest at many russian products)

    3- Can steam catapults work in the arctic?

    No point in wasting time and money developing steam catapults today... they are inferior to the potential of EM cats, and most importantly technology developed creating steam catapults is not useful... technology created developing EM cats would be very valuable in all sorts of areas.

    Not for long before having maintenance & safety issues. Steam will add moisture on the flight deck leading to ice buildup.

    Ice build up has always been a problem in arctic waters anyway and could be dealt with, but the fundamental problem remains that a steam cat is not worth developing now... it wont be any easier or quicker or cheaper than EM cats would (for Russia who has never operated one on a ship before), so it makes sense to invest in an EM cat instead.

    MiG-29k/35 in 2030s? like investing in frame from 80s? 50 years old design? ekhm doesn't look too promising for me. Recently there was 10 years from the first flight of Su-57 and no Su-57k on horizon. Yet I hope VSTOL is still in development. In 30s should be on table

    It is likely that even in the 2030 period the French will still be operating Rafale and the US will be operating the F-18 which are contemporaries of the MiG-29/35.

    A VSTOL would be an enormous step backwards... a navalised Su-57 or a new medium 5th gen fighter based on the MiG make rather more sense. There is plenty of time to decide because the carrier itself will take a decade to get made and anywhere near service anyway.


    Thats to me most intriguing part. Ka-31 is the cheapest but functionally the worst option for AWACS. Lower ceiling then E-2 10,500m vs 3,500m for Ka-31. Mission time 2,5hrs for both but E-2 can be refueled and fly 5 hours on mission.

    The extra height is irrelevant... the Ka-31 can see to sea level out to 250km... operating at 10K altitude wont change the distance it can see to... it would just make it visible to other platforms from further away.

    Another factor you ignore is that a spread out surface group will have lots of ships with helipads where the Ka-31 can land and refuel without having to fly back to the carrier and being smaller and lighter and rather cheaper you could operate half a dozen of them and position them around the carrier group with a corvette or frigate nearby with a heli pad to keep them in the air...

    It is not ideal obviously, but certainly better than nothing.

    Even with EM cats they will likely still use them...


    Investing in (never finished) Yak-44 is like restart the 50 years old design. The new platform for 2030s? US BTW USN has just started replacing own Grumman C-2 Greyhound with tiltrotors. Which do not require any catapult. C-2 is same airframe as Grumman E-2 Hawkeye AWACS.

    An airship could operate at enormous altitudes continuously for months at a time with no need for a catapult and could be fitted with antenna arrays that are enormous too. Its lack of speed is not really an issue because with flight speeds of 100km per hour even a conventional airship can move with any carrier group.

    The technology needed for EM cats would be useful for developing long range artillery and for electric powered propulsion systems etc etc the investment in EM cats wont be wasted... unlike money invested in tilt rotors and VSTOL fighter aircraft.

    It would be interesting to see ho thins will develop on US/NATO side

    Interesting but not particularly relevant.

    P.S. how do you know that no Su-57K will be developed?
    The new carrier will not start trials (in the best case) before 2030. There is plenty of time for it.

    I remember in the 1970s the models showing brand new Soviet carrier designs had MiG-23s on them... when we saw the fixed wing carrier it had Su-27 and MiG-29s on it... they are not stupid... they will plan for aircraft and if they have to make aircraft to operate from the carriers then those aircraft will be adapted to work.

    Unlike US and western aircraft carriers Russian ones don't require a catapult to launch fighter aircraft because their fighter aircraft are expected to be used as fighters rather than multirole aircraft so the requirement for weapon loads is much less. A full air to air missile and jammer pod load out is small compared with an air to ground loadout.

    The cats for the new carriers will be for AWACS platforms... manned or unmanned... new or based on old... their work on brand new radars might mean their new AWACS platform has tiny lightweight radar arrays that can be fitted to smaller lighter aircraft... a scaled up more powerful Ka-226T that can operate at 7km altitude for instance could be an option... they might be able to mount the new antenna arrays on existing aircraft skin so a MiG-35 might have front and rear facing radar antenna and engine side wall mounted antenna for 360 degree scanning so it can be used as an AWACS platform... they could fill in the centre location between the engines with a low power turbofan engine... the aircraft could take off normally with two main engines accelerating the aircraft and climbing up to 7 or 8 thousand metres altitude and then the centreline cruise engine could start up and the FOD doors over the two main engines could close to minimise drag and it could loiter on this low power turbofan engine for 7 or 8 hours... buddy refuelling could extend the amount of time it spends on station, or it could be replaced when needed...

    Anyways there would be no point in developing catapults and building a 75000tons carrier if you only plan to use tiltrotors, helicopters and stovl aircrafts.

    That is the trap... we have VSTOL fighters and helicopters and tiltrotors so instead of a 75K ton carrier we have a 20K ton helicopter carrier like the Hermes which is much much less capable than a real carrier.

    A false economy.

    But those who support this should also be suggesting that Su-35s and Su-30s should be withdrawn and replaced with cheaper lighter MiG-29s and MiG-35s... they do the same job but the smaller lighter aircraft cost less to operate...

    [qutoe]if Russians go for catapults there will be much more sense in investing into EM catapult. Less mechanically complex, reduced crew requirements and more starts per minute. No problems with icing of condensed steam . [/quote]

    And technology that can be used in other areas...

    Extending range for artillery guns for instance...

    it is upgraded 80s design in plain words. It is a good stopgap but it doesn't really looking like a perspective fighter to counter US/NATO 6th gen fighters. For Kuz it woulds make sense as Kuz is back soon. OK relatively soon in line.

    For now it makes sense... it is capable and affordable... and the 6th generation Russian fighters that replace it don't exist yet anyway.

    I dont but about carrier there were a lot of discussions in Russian media sphere since 2014. But nothing wrt to Su-57k really. Only 2-3 times mentioned VSTOL development since 2017 (AFAIR)

    R-37 being compatible with all the new Russian fighters... Su-57, Su-35, MiG-35 and of course MiG-31, but we have only ever seen it on MiG-31s and mentioned for Su-57... but now we see it on Su-35... how long before we see it on MiG-35?


    2) And US will use E-2 till the 2030s when next gen will appear. V-22 is replacing C-2 for a reason. USN has 90-100ktons CVNs with catapults yet replaces C-2 with V.22. There must be advantage I guess.

    Maintenance is usually the excuse... the F-18 replaced the F-14 because it was "multirole" and cheaper to operate and maintain... which is of course bullshit in terms of multirole because they specifically did not upgrade the F-14 with a lot of things like AMRAAM to make it obsolete so it would be replaced... I suspect the company that makes the C-2 no longer exists and they can't make any more but the maker of the V-22 wants the job so it is creating work by developing a replacement where none was really needed.

    Ironic that the F-15 was taken out of production so the F-16 and then the F-35 could be made in larger numbers to replace them... now they are talking about putting the F-15 back in to production... ironic... the F-35 was supposed to save money


    3) UK from the other hand has 2 70k CVs without catapults and VSTOL ;-)

    They also went from fixed wing carriers with cats to the Hermes vstol carrier... it was not a military decision... it was an accountants decision because every time the British military are sent out to do a task the first thing the british government does when they get back is cut their budget to offset the cost of munitions and the war.

    Not a good model to follow.... any brit will tell you that.

    Their life will be extended till 30s but it is already legacy tech. And if RuN is going to use upgraded 80s designs (MiG-35, Yak-44) then they will invest into yesterday's tech vs US tomorrow's tech.

    Bullshit.

    Aircraft technology in terms of design and materials and manufacturing has moved on since the 1970s... basing a design on a model from the 1970s does not mean it will be a 1970s design, but if you believe that then that would be a very good argument against VSTOL fighters.

    If F-35 represents US tomorrows tech then Russia is in an excellent position because American future tech is crap... going for tilt rotors sounds to me like they have reached rock bottom and are still digging.

    They could adopt the Mi-38 with ~2x Ka-31 ceiling (6,500 m) & range:

    Range and altitude are not critical for AWACS... its purpose is not to look for targets thousands of kms away... it is to detect low flying and sea surface threats early so they can be engaged earlier and quicker and with coordination.

    The most likely replacement for the MiG-35 on Russian carriers would be the Su-57 with folding wings. Should be a straight forward upgrade.

    I suspect the company that makes the C-2 no longer exists and they can't make any more but the maker of the V-22 wants the job so it is creating work by developing a replacement where none was really needed.
    The Northrop Grumman is still active, & now works on the B-21.
    https://en.wikipedia.org/wiki/Grumman_C-2_Greyhound

    Instead of developing a new plane or restarting C-2 production, the V-22 was selected to save $- the Navy version is also useful for SAR, ASW & special ops. Also, COD can now be done safely at night, giving them more flexibility & reducing CATOBAR use & maintenance costs.

    Range and altitude are not critical for AWACS...
    Bigger range=more patrol time w/o refueling; higher altitude may mean faster speed to reach a given patrol area & grater target detection range.

    Do they still support operational Hawkeyes and are they capable of making or even interested in making more?

    That is like saying MiG could start building MiG-3 fighter planes because MiG still exists as part of the UAC organisation... but the facts are that the guns and engines and many other parts needed are no longer in production so while they probably could make a few hand made versions it would not be practical or useful to put them back into production and I doubt even MiG would be interested in such a thing.

    V-22 stats are pretty ordinary and don't really impress me very much... the C-2 can manage 4.5 tons with a cruise speed of 460km/h to 2,400km range... Wiki gives no cruise speed for the V-22, but as a general rule of thumb cruise speed is about 80% of top speed which gives us a cruise speed of about 400km/h, and while it can supposedly carry 9 tons of payload its combat range is about 700km... an Mi-26 could do better than that...

    I also don't really trust numbers for the V-22... for the same reason I don't trust figures for the F-35 either....

    Bigger range=more patrol time w/o refueling;

    Not at all... a helicopter is much slower than a fixed wing aircraft so a flight range that is a quarter doesn't mean a quarter of the endurance... helicopters can also land on any ship with a heli pad and does not need to return to the carrier for refuelling...

    higher altitude may mean faster speed to reach a given patrol area & grater target detection range.

    The Ka-31 can only see to 250km so getting higher than 3,500m is pointless because any extra height wont extend the radar range... it will only make the helicopter visible to surface ships that are further away...

    Higher flight speed is largely useless to AWACS platforms...

    Yeah higher speed is not needed for awacs, but if they build an AWACS Yak-44 derivative, they can also build a tanker version and a cargo/transport version.

    Don't worry: they r already test flying a MQ-25A UAV tanker.
    https://news.usni.org/2019/05/06/navy-first-mq-25a-stingray-flight-planned-for-later-this-year

    The MQ-25A will deliver up to 15,000 pounds of fuel at 500 nautical miles. (926km) https://news.usni.org/2019/09/20/boring-first-flight-of-mq-25a-prototype-was-the-result-boeing-and-navy-wanted
    https://www.theunitconverter.com/nautical-miles-to-kilometers-conversion/500-nautical-miles-to-kilometers.html

    I'm sure it could be used to refuel the V-22s. 700km+926km=1,626km. They may even have a dedicated V-22 tanker version.

    a helicopter is much slower than a fixed wing aircraft so a flight range that is a quarter doesn't mean a quarter of the endurance... helicopters can also land on any ship with a heli pad and does not need to return to the carrier for refuelling...
    True, but a large helo of the Mi-38 size can have extra fuel tank(s) for more loitering time & a pusher prop in the tail to give it more speed; OTH, it'll be too big to land on FFGs & DDGs.

    Yeah higher speed is not needed for awacs, but if they build an AWACS Yak-44 derivative, they can also build a tanker version and a cargo/transport version.

    They could make it a biplane like an An-2 with double folding wings... its takeoff speed is so low that it could probably take off from an aircraft carrier that is running in to the wind without a catapult... all sorts of versions could be developed...

    An upgraded Yak-44 with new engines and propellers made of modern composite materials and new lift features on their wings like blown flaps could make a very capable small AWACS aircraft that could be sold to countries that don't even operate aircraft carriers... India it seems could do with aircraft to coordinate its fighters during skirmishes on its borders and they could probably buy a dozen for the price of a full sized AWACS platform...

    True, but a large helo of the Mi-38 size can have extra fuel tank(s) for more loitering time & a pusher prop in the tail to give it more speed; OTH, it'll be too big to land on FFGs & DDGs.

    First of all a bigger helo could land on frigates and destroyers... what it couldn't do is fit in to their hangars because they are designed for Kamov Helix family aircraft.

    Second any improved helo based AWACS for the navy will almost certainly be a Kamov... most likely based on the new models they are working on now.

    The technology they are working on for small UAVs on tethers that can be used by Armata tanks that raise thermal imagers and MMW radars in to the air to look down and around the vehicle with data and power provided through the tether suggests a potential future with hydrogen balloons lifting sensors above a ship so they don't need rotary or fixed wing aircraft to search the airspace around them out to significant distances down to low altitudes...

    In fact you could pallatise it like the new Naval TOR system so you could place it anywhere on the deck that has free space... inflate the balloon using water and a fuel cell to generate hydrogen... and to then consume it for recovery purposes... so there is not too much tension on the tether...

    possibly incl. the Ka-102. It'll have the range, speed, & payload to be adopted for EW&C role besides COD, SAR, ASW, MCM, & special ops roles.

    I'm sure some1 already thought on this, but since no such concept appeared up to date, I doubt it'll be feasible in the long run.

    The Soviets and Russians have a recent history of showing failed designs and revealing failed systems in the hopes of finding a foreign partner to invest in developing the product... case in point the Mi-28 was revealed in the late 1980s... it was about 4-6 years later when real images of the Ka-50 were shown... both the Mi-28 and the Ka-50 were good designs but at the time the Ka-50 was considered better though it was more expensive. The new requirements for night and all weather performance meant the Ka-50 was eliminated and they started looking at the Mi-28 again because flying a helicopter at night is a full time job so you need a weapon operator as well.

    The point is that the Russians might not be revealing AWACS design plans at all so how can we tell what options they are looking at?

    Their model ships show Yak-44 like AWACS... but as I have mentioned the models from the 70s showed MiG-23 as carrier aircraft as it was the standard fighter aircraft of the time. When the carriers were in the water however there was the Yak-141 (replacement of the Yak-38M) and the MiG-29 and Su-33 (replacements for the MiG-21 and MiG-23 respectively) that were carried.

    The people developing new ships can communicate with the people developing new aircraft so new ships will have helicopter facilities able to handle new helicopters as well as current ones... new aircraft carriers that wont be in service for a decade will plan to have new aircraft too... at least as an option...

    An important part of the design process is to ensure your new product is going to be compatible with products in development.

    I mean they would hardly develop the PAK DA only to find all the brand new cruise and hypersonic missiles they are also developing wont fit internally... the makers of weapons will talk with the makers of planes to ensure they work together and are standard.

    Will be the same for carrier designers.

    Certainly not the Ka-102 for a couple of reasons... first of all because it likely wont get made. Second because even if it was made it would take up an enormous space inside the carrier and would be totally inferior to any fixed wing AWACS platform they develop... you could probably carry four Ka-31s for each Kh-102 so no matter what performance you get from the Kh-102 the existing already developed and in service Ka-31 makes rather more sense.

    It is possible they might make them for land based use... but with other new helicopters funded and in development I rather doubt they would make any money at all on it so they will likely shelve it.

    Well newest US carriers can't operate newest US f-35... shit happens somtimes and cost a lot.

    There are many things engineers can't think about when developing something and realize that in the best case only during tests and in the bad case when they already sold lots of equipment that then need to be fixed for a big price.

    A little bit like when car makers call back thousands of cars because there is a part that need to be changed.

    something has to replace the Mi-6; a shorter version can be made for CVNs, or it can stay on the flight deck or some other ship; fixed wing AWACS may not materialize & EM CAT will take a lot of $ & time to develop & test, besides requiring a lot of power, space, & extra personnel to operate & maintain.

    Well newest US carriers can't operate newest US f-35... shit happens somtimes and cost a lot.

    The newest US carriers can't operate the cat launched F-35s because their cats don't work yet... give them time and a few billion dollars and they will get it working eventually...

    We keep hearing about how wondering the F-35 is... I would think from such a physically large ship as the Ford class they could just take off conventionally with air to air loadouts if they needed to... has the conventional cat assisted take off F-35 have main engine thrust vectoring?

    There are many things engineers can't think about when developing something and realize that in the best case only during tests and in the bad case when they already sold lots of equipment that then need to be fixed for a big price.

    That ship has already sailed... they have spent enough on Ford and the F-35 to fix any possible problems 100 times, but in actual fact it seems most of the money that went into the F-35 was wasted in the method of production that made it cancel proof... did they know it was going to be a dog from the outset and make it the way they did to prevent common sense from stopping it? I mean the whole point of the F-35 programme was standardisation and unification of design and components to make it CHEAPER... so far it has only made it orders of magnitude more expensive... I mean the Russians are making the Su-57 for 40 million each, while the price for the F-35 seems to be three times more than this...

    The excuse that they can afford it while the Russians can't is pretty damn weak... if anything the Russian aircraft should be much more expensive because it doesn't use imported parts...

    A little bit like when car makers call back thousands of cars because there is a part that need to be changed.

    True... but generally it is only one thing... a faulty airbag design or a fault in the brakes, or an electronic problem with something... the sort of thing they try very hard to solve before they start selling it to the public... it seems that in the case of the F-35 it is more like the microsoft method of getting the product out and making money from it and then fix problems in a slap dash way with patches and workarounds as they turn up and then after a period put out a service pack to fix the major problems... usually the OS is stable and relatively reliable by service pack 3.

    Not a good model for fighter aircraft though.

    something has to replace the Mi-6; a shorter version can be made for CVNs, or it can stay on the flight deck or some other ship;

    The Mi-26 replaced the Mi-6 years ago... and this new 10-12 ton payload helicopter joint venture with China will fit in the appropriate niche to make any other helicopter type redundant in that role. They don't need a Chinook or a Ka-102 AND this new helicopter, and considering this new helicopter is rather more likely to proceed once the engines are ready then it makes little sense to waste time talking about a Chinook or Ka-102 which in Russian service would likely use the same new engine so would be delayed the same amount of time too before it could enter service...

    The Chinook has zero chance of entering Russian service as I keep telling you, and the Ka-102s chances are not that much better for the reasons I have explained.

    fixed wing AWACS may not materialize & EM CAT will take a lot of $ & time to develop & test, besides requiring a lot of power, space, & extra personnel to operate & maintain.

    Money spent on EM cats is money well invested because the technology an materials invested in electromagnets and even just the transfer and use of large amounts of electrical energy will be seriously valuable across an enormous range of fields... with all electric aircraft and land vehicles and ships and subs such technology can be used across the board from cars to trucks to trains to armoured vehicles of all types, through airships and drones and all types of aircraft manned and unmanned.

    An EM cat system would require less personnel than a steam cat system, and would not require enormous amounts of super high temperature steam under very high pressure to be piped through the ship... such things are incredibly dangerous in war scenarios in terms of battle damage.

    Equally a steam system needs to be set precisely for the aircraft type and for its fuel and ammo and payload status... dial it up wrong and the aircraft either gets its nose wheel ripped off and probably ends up in the water because it wont be moving fast enough to raise its nose when it gets to the end of the deck and will just drop straight in to the sea, or the cat does not deliver enough speed to the aircraft to get to takeoff speed and when it gets to the end of the deck with its nose turned up its lack of speed means it will sink down from lack of lift till it hits the water and sinks.

    With an EM system the system can adjust the force it is delivering so if it senses the aircraft is not accelerating fast enough it can increase power to get it to speed in the space available. If it starts moving too fast it can reduce the energy to avoid damaging the aircraft and still get it to flight speed...

    In terms of electrical power it wont be that much different from the power delivered to the 4 main antenna arrays of the CVN itself during peak search routines scanning at long range for stealthy targets... such vessels with nuclear power plants should have plenty of excess power to play with... it will also have back up generators and other systems to temporarily increase available power when needed too... but as I keep saying these cats are not for launching Russian fighters... Russian fighters with the ski jump and sailing in to the wind should be able to take off with max fuel and max air to air payload without needing cat assistance... so the only aircraft needing the cats will be the AWACs and any other large aircraft types based on that design like a COD/tanker platforms that could have their design unified fairly easily...

    Yak-24K The fuselage was shortened,...

    There are limits to how much you can shorten the fuselage of a tandem rotor helicopter design... in comparison a coaxial rotor design is about as short as you want to make it... with most of the benefits of a tandem rotor design...

    The Mi-26 replaced the Mi-6 years ago...
    it wasn't's a not a direct replacement any more than the An-12 was of the An-8- it increased vertical lift capability exponentially along with the operating costs.  
    ..and this new 10-12 ton payload helicopter joint venture with China will fit in the appropriate niche to make any other helicopter type redundant in that role.
    like I wrote on the other thread, they won't buy it in any meaningful #, if at all. Better make its own helo.
    Money spent on EM cats is money well invested ..will be seriously valuable across an enormous range of fields...
    they can invest in MAGLEV trains with the same result, saving $ on EM CAT & fixed wing AWACS & CODs by adopting helos or tilt-rotors.
    A few EW UAVs can help AWACS helos making them=the USN E-2s.
    There are limits to how much you can shorten the fuselage of a tandem rotor helicopter design...
    if the future CVN is going to be as large or larger than the Nimitz/Ford classes, it won't make a big difference, even if its close to 2x as long as CH-46E & CH-47F, both of which operated off LHAa & CV/Ns. 1-2 of them could be based on it & the other 1-2 or all 4 on other ship(s).
