    I also would like to see the A-42 back in business - and apparently their are plans - but it was and still is a only replacement for the ancient Be-12.

    The thing is that we don't have all the statistics of use that they do with the Mail.

    I mean if it was critical and saved lives because it could land on water and moving forward there was expected to be future requirements for perhaps long range amphibious aircraft then the A-40 and the A-42 were very good designs... state of the art for what they were, and finally getting them into production and service would be a good thing.

    The only thing they really needed improving was the engine arrangement but that was intentional because the lower thrust engines running in flight without the boosters used for takeoff mean lower fuel burn in flight, but newer engines will not only be so much more powerful that they wont need the extra weight and complication of the two extra engines, but they will also likely be more fuel efficient too.

    All the avionics would need to be upgraded too but they will want all Russian stuff anyway.

    I'm sure they have plenty of reasons. One such is that a prop aircraft can fly much slower than a jet engine aircraft. This is apparently quite useful when attempting to track subs in the deep with MAD.

    Very true, but the exception is the Bear because of its swept wing it is rather fast and has a higher stall speed than a straight winged aircraft of its size would have which creates a problem. They have a long wire they hang out of the aircraft with a drag on the end that they use for communicating with submerged submarines... I seem to remember it is exceptionally long... over 1km, but needs to hang nearly vertically for it to work and its use is rather dangerous in the Bear because the speed where it hangs almost straight is very close to its stall speed.

    Obviously a straight winged aircraft should not have such problems flying slow...

    I think Russia making their own version of the Chinese AG600 would be more useful for ASW than reviving the Beriev A-40.

    Do you think the AG600 is more sophisticated than the A-40/42?


    Not so easy. Il-112V uses the same engine and is still struggling getting into service.

    Who said it is struggling... most of the shit about the Il-112 and Il-114 and other types is just internet bullshit.

    The development of aircraft never goes perfectly but anytime some problem comes up poofters on the interweb demand it be cancelled and a foreign aircraft type chosen... well Russia currently has a few problems with transport aircraft and civilian airliners and most of those current problems centre around the previous decisions to buy foreign types... why make that mistake again?

    A longer il-114 with 4 engines isn't an il-114 anymore.

    Just like the Tu-334 isn't a Tu-204 anymore either but the designation does not matter as long as the modified aircraft is better suited to the job.

    Tu-204 with seats and equipements for civilians can carry 25t.

    You are missing the point... the rocket powered Kinzhal benefits from being released as high and as fast as possible. Scramjet powered missiles like Zircon it wont matter so much.

    Equally they are talking about a new MPA... we don't really know if they just want one, or if they want to replace both the aircraft they operate at the moment... the Tu-142 and Il-38 May are very different sized aircraft with different roles... I suspect the naval strike roles will remain with the Tu-22M3M and perhaps eventually be replaced by the PAK DA... or maybe Tu-160 for it speed. (when they have a lot more than 15 of them).

    No but having a similar plane experiencing huge design issues will make them think twice about creating a bigger plane based on them using the same engines.

    What huge design issues? Perhaps you are confusing it with the Il-112 which had some problems with the prototype and when they were fixed there were problems with the engine setting fire to the wing and then shutting down and not feathering the blade and crashing, but that would happen to any propeller driven aircraft whose engine does not feather the blades... that would be like deploying a super air brake... of course it will roll over and crash... that has nothing to do with a faulty design.

    Tu-214 is already used for special mission planes, they have plenty of remaining bodies in the hangar and have the production line for more to be build.

    The Tu-214 is the open skies aircraft and I suspect its performance means they might make more as spy planes, but there are Tu-154Ms and Tu-134s and Il-20s and Il-22s and quite a few old types that need replacing too.

    We really have no idea which aircraft they will be basing a new ASW aircraft on other than it will use four propellers... perhaps they have looked at Americas experience with the P-8 and don't want to make that change... they might have HALES and MALES that are also propeller driven and they want them to be able to operate together in terms of speed and altitude, or perhaps the HALE might mean their MPAs don't need to operate high up and can be optimised for lower altitude flights.

    I understand your point. What I disagree is that you make it sound like you just need to miltiply the il-114 by 1.5 and add 2 engines to get a Il-114MAX.


    That's not so easy.

    It would be easier than what they did to the Tu-334 to convert it from the Tu-204... they took all four engines off the wings and put two on either side of the tail and changed it to a T tail aircraft.

    The point is that the aircraft they are talking about is to replace the Il-38 and the Tu-204-300 has a flight range of 9,300km with 166 passengers.... they could improve the Tupolev design... lengthen it and add more fuel and it could be the replacement for the Tu-142, and keep its jet engines... perhaps a drone that flys below the aircraft and pulls the wire straight to communicate with subs deep under water?

    The focus should be on Russian engines and Russian aircraft designs, but also filling gaps.

    When the Il-38 entered service as an MPA it wasn't a state of the art airliner that was super efficient and cost effective, but it has been a good reliable workhorse.

    Having new designs based on other designs makes sense... the Il-276 and Il-476 makes sense... sharing fuselage cross sections and shapes if not lengths and widths and having the same engines is useful and ideally they should do it again with the Il-106 in the 90-110 ton payload class with two PD-35 engines and a Slon scaled up aircraft with four PD-35s in the 180 ton payload capacity... you wouldn't really need the An-124s any more.

    The Il-106 being smaller and lighter but able to carry 90% of the different loads the An-124 carries means it would be the numbers plane, while the Slon would be made in smaller numbers, but its design should be relatively cheap as it would just be a scaled up Il-106 with twice the thrust.

    Russia is still using mostly soviet designs. Most of 100% russian designs struggle getting in service. Even the il-112, a small turboprop ended with a huge problem or are full of western tech like Ssj-100.
    But yeah if random dudes Mir and Alamo said they can just double the size of the il-114 in few months that must be true.
    Again there are facts and there are wishful thinking of some guys on a forum. Get real man.

    What an incredible telling post this is! You are absolutely clueless Shocked

    Here is laughing back at you >  Laughing  Laughing  Laughing

    The  Soviet's first attempt to build a replacement for their ancient cargo planes was known as the An-8. It was fitted with 2x Ivchenko AI-20D turboprops. They had some issues with the design but were produced in numbers for the Soviet Military.

    ASW Aircrafts for Russian Navy: - Page 15 800px-10

    They then took this basic design and and developed it into the An-12 with four engines (Ivchenko AI-20L turboprops). This aircraft became one of the most successful aircraft in modern military aviation. So you see Isos it can be done.

    Even the French did it with the Mirage 2000 and the Mirage 4000 - and I almost forgot about the Mirage IVP - so get real dude!  Laughing

    Except the engine the Il-114 uses is a mess and was at least partially responsible for the loss of the Il-112 prototype with all its crew.
    So now they are supposed to scale the Il-114 to a quad engine aircraft with those same engines?

    Sorry but I do not buy it either.

    I also do not see what is the point in scaling it up in the first place. There are C-295 variants for sea patrol with the same engine power as it has, and other sea patrol aircraft like the ones Japan or the US use, the P-1 and P-8 Poseidon, have way more engine power. At that point you are better off turning an MC-21 or Tu-214 into such an aircraft.

    But that is not even the point.

    The discussion is about a new plane made by expanding the existing project.
    Scaling up, doubling the engine number.
    It will be a totally new plane in reality, but with an obvious base.
    Just as was practiced multiple times in the history of aviation.
    Is it easy? No.
    Is it easier than making a whole plane from scratch? Yes.
    So disputing that is pointless - those things have been done multiple times.

    A major point is role.
    Is this a long range ASW aircraft, or inshore?
    Things like the C-295 might be fine for nations who are interested in ASW inshore, but further out range and payload characteristics become important.
    How many users of the C-295 Persuador use it for ASW far beyond inshore work?

    I can see the need for a certain number of Il-114's for inshore work, and a certain amount of Tu-214's for longer range work.
    They could leverage many of the same ASW systems for both airframes.

    Russkie geography determines that.
    They just need different platforms having small, closed seas at their borders and a waste of Pacific or Arctic.
    Using a Tu-142 size plane to patrol the Baltic is just a waste of a good plane.
    That is why the lovely flying museum Be-12 was still in use by the Black Sea Fleet only a few years ago.
    Not sure now dunno

    By the way do you believe that both a slower il-38 replacement and the faster Tu-142 are needed in that role?

    And could the Tu-142 be replaced by a ASW version of the Be-42 (A-40) or of the Tu-204?
    (India replaced its tu-142 with the smaller Boeing P8 (737 derivative) in 2017)

    In that case could the tu-142 be converted into strategic bombers ?

    Anyway, I am curious now on why western countries are now basing their ASW aircraft only on fast passenger (or business) jets.
    I am not saying they are right, I am just curious on why they deemed a slower cruise not anymore needed for a naval patrol aircraft.

    It would not be the first wrong decision that is later reverted, anyway, like the "lack of need" of dogfight capabilities during the Vietnam war or the excessive importance given to stealth and fifth generation aircrafts, which are an important niche but not a "one size fits all" solution (also reverted now, with new production of f-15 aircrafts).

    Broski, The AG600 is still a prototype and I doubt its development is more advanced than that of the Be-42/A-40/A-42 (3 names for the same aircraft Very Happy ).

    Furthermore the Soviets/Russians had and still have a much larger experience in designing and operating Amphibious aircrafts than the Chineses.

    GarryB, I like the Be-200 and I am glad that that it will have now its new domestic engine in the PD-8, but it is still small if it has to replace the Tu-142.
    Furthermore it is not good to leave the Chineses the top spots in the largest amphibious aircraft in production.
    The AG600 is larger than the Be-200 but smaller than the A-42.

    The A-42 is a great aircraft. It just needs new engines (either PS-90 or PD-14) and a new set of modern internal systems (which have already been developed for other aircrafts).


    So maybe in the future we will see the Il-38 being replaced by the new 4 turboprops il-114 derivative and the Tu-142 replaced by the A-42.

    They then took this basic design and and developed it into the An-12 
    An-12 was developed from the An-10.

    Quite correct but with a twist Wink

    The An-10 was developed as a civilian passenger airliner whilst the An-12 was the military cargo version.
    The An-10 was less successful as it suffered from structural problems though and was quickly withdrawn from service.

    So now they have a problem with one of the Klimov TV7-117 engines specifically developed for the IL-122V - so lets just chuck the whole damn engine (and the project) in the dustbin because of a nasty accident that was due to pilot error if I remember correctly!?

    AND not just the Il-122 but the IL-114 and the Mi-38? I don't think so!

    The main difference between the Tu-142 and the Il-38 is that the former is operating on a "strategic" level covering huge distances from Russian territory - just like the Tu-95MS, but in a different strategic role. The Tu-142 is much faster than the Il-38 but it can operate at fairly low speeds as well if the need arises.

    There is zero chance that the Tu-142's will be converted in strategic bombers. In fact they will probably restore some of the reserve stock back into maritime patrol duty due to the new naval doctrine. These airframes are still young and can serve for many years to come. All that is needed is a periodic systems upgrade.

    There was no pilot error. There was a catastrophic engine failure, the pilot tried to use the fire extinguishers, and they failed to put the engine fire out, they tried to feather the engine, and that also failed. It was just a catastrophic sequence of failures, and most of it was the engine. It basically blew itself up into tiny little pieces which cut the lines to the fire extinguishers and the feather controls. So it is quite rich for you to say it was a pilot error.

    Now I hear they made a digital version of the engine and will be redesigning it for the TVRS-44 aircraft. So maybe they will fix the issues. But who knows.

    Tu-142 were produced till the mid90s, so from the strategic aviation perspective, we talk baby age.
    Yet the fuselage differs much from the Tu-95, and I guess that converting them would be costly even if considered.
    Much easier would be to refurbish some older Tu-95M that were taken out due to START.

    Maybe I'm confusing it with another crash but as far as I remember there was a fire in one of the engines and the pilots followed the wrong procedure and that in turn led to catastrophic failure? (Something with the way they feathered the engine?)

    Yeah, i remember the crash had something to do also with the propeller feathering.
    Possibly if the test pilots had known about this possible failure mode in advance they could have prevented the tragic consequences, but I absolutely do not believe it was their fault. From my understanding they followed the correct procedures.

    It was a very unfortunate accident and it was probably a combination of various failure modes that were not properly explored. However this does not mean that the engine is all crap.
    A huge mistake was done and it costed the life of several people. The only silver lining is that this has been seen during aircraft development so the victims were only 3 instead of being several dozens.

    Anyway that failure mode will be corrected and all the various versions of the engine (for the il-114, for the TVRS-44 and for the Mi-38) will be safe.

    I do not know if this will also cause delay in the development of the PDV-4000 (a 4000-5000 hp turboprop and turboshaft engine of new generation) which first prototype was planned to be build in 2025 according to what was announced in August 2020 and which will be perfect for the next generation of Russian military cargo planes (among the rest).

    https://www.aex.ru/m/news/2020/8/24/215969/

    This new engine should be a larger and more powerful evolution or derivative of the VK-2500 and TV7-117 engine family (4000-5000 hp vs 2500-3500 hp) and should also be the real successor of the Ivchenko AI-20 which was developed and manufactured in Zaporozhye.
    (Same power range of the C-130/C-27J engine)

    By the way the Chinese WJ6 engine used in the Y-9 military trasport aircraft (copy/derivative of the An-12) and on the amphibian AVIC AG600 is just a copy/derivative of the old soviet AI-20 (used on An-8, An-10, An-12, il-18, il-38, etc).

    According to one of our own posters Russian_Patriot_ the overheating problem was known beforehand.

    There is also unverified information that they (Ilyushin Design Bureau) knew about the problem with heating the right engine, but decided to take a risk to arrange a show-off for the "big bosses" at the Army-2021.

    If this is true, then the heads will fly off the shoulders of those idiots who allowed it...

    According to TASS a criminal case was opened on charges of violating flight safety and aircraft operation rules.

    I have no idea how this issue was resolved.

    Yesterday's Aviation of Russia provides further details:

    Work to replace the Il-38 anti-submarine aircraft with a new one is already underway, 03.05.2023.

    Development work has begun on the creation of a basic anti-submarine, reconnaissance and patrol aircraft, which should replace the Il-38. The new vehicle will expand the range of weapons, the range of ammunition will be larger. About it informs RIA Novosti with reference to an informed source.

    “The new machine will retain the four-engine scheme standard for aircraft of this class, it is planned to be equipped with TV7-117 turboprop engines,” it said.

    The source did not disclose the parameters of the future machine, but noted that its flight characteristics "will be typical for turboprop anti-submarine aircraft." The new machine will receive modern on-board equipment, including an on-board computer and a multifunctional search and sighting system, as well as sonar buoys, the source added.

    The aircraft is planned to be almost completely built on domestic electronic elements and components, the source of the agency concluded.

    Il-38 is an anti-submarine and medium-range maritime patrol aircraft, created on the basis of the Il-18 passenger liner and produced in 1967-1972. In total, 60 units were built in the USSR, the latest modification is the Il-38N. In the basic version, the aircraft is equipped with sonar buoys to search for submarines and various anti-submarine weapons - depth charges, torpedoes and mines. The modernized version of the Il-38N is equipped with a multifunctional search and sighting system " Novella " with a detection range of surface ships over 320 kilometers. The system is capable of simultaneously tracking several dozen underwater, surface and radio-emitting targets.

    The combat radius of the Il-38 / Il-38N reaches 2500 kilometers, the maximum speed is 650 kilometers per hour, the maximum flight altitude is 10 thousand metres.

    Now there are about 25 Il-38 and Il-38N in the Russian Aerospace Forces, however, there is no reliable information about how many of them are in service. According to World air forces data for 2022, 21 Il-38 aircraft are indicated in the Russian naval aviation. In the Military Balance handbook (p. 198)indicatedone regiment and two squadrons of Il-38 / Il-38N, which for aircraft of this class corresponds to 24 aircraft.

    Despite the fact that the RIA Novosti source did not say on the basis of which machine the new anti-submarine patrol aircraft is being developed, it was previously reported that the Il-114-300 could become the basis for such a development . This is indirectly confirmed by the words of the interlocutor of the agency about the engines of the TV7-117 family. IL-114-300 is equipped with the TV7-117ST-01 version.

    In December 2018, the head of the naval aviation of the Russian Navy Igor Kozhinsaidabout plans in the period from 2021 to 2030 to begin mass production of a promising aviation patrol complex.

    He previously stated that the new development would replace all patrol aircraft in the fleet of naval aviation. “We are talking about the creation and commissioning of a new unified platform,” said Kozhin.

    The Russian Ministry of Defense has high hopes for the Il-114-300 passenger turboprop aircraft . At the end of 2017, our website reported that the military department plans to replace the Il-20 reconnaissance aircraft with a new machine, which will be created on the basis of the Il-114-300. Then it was reported that tactical and technical requirements for a new reconnaissance aircraft based on the Il-114-300 were being formed. Work on the new aircraft was to begin immediately after the updated passenger airplane took off.

    Except the Il-20 engines have like twice the power. This will basically be something competing with the C-27J or the likes rather than the Il-20.
    Considering the lackluster track record in sales of the C-27J it seems like a waste of resources to me.

    @Lancelot

    You do know that as time progresses so does technology? Systems, structures, components and sub-systems tend to either get lighter and/or smaller so you don't need a rocket to get the thing airborne. Also engine development is an ongoing process to improve and give the engine more power. The latest versions are already more powerful than the original.

    AND this thing will have 4 engines - so no it's not a CJ-27...it's not even a cargo plane.

    I think it's pretty clear from Kiko's post above what aircraft they intend to use for further development. I do hope it does come off the ground as this is actually a long overdue and vital requirement.

    Mir wrote:They then took this basic design and and developed it into the An-12 with four engines (Ivchenko AI-20L turboprops). This aircraft became one of the most successful aircraft in modern military aviation. So you see Isos it can be done.

    I never said they can't. I said Russia will struggle making an enlarged il-114 with 4 engine because it won't be an il-114 anymore but an all new plane and the il-112 which is in the same class as the already existing il-114 is almost a failure. So imagine a bigger plane with 4 engines... tu-214 exist and is a better plateform that is already built.

    Arguing with soviet equipement is useless dudes. Soviet and so iet engineers are long gone. Russiand manage to maintain and improve existing soviet planes like tu-95 or tu-160 but when it comes to creating new aircraft they lost too much expertise so they struggle creating new planes.

    Ssj-100 is a failure even with French assistance. Il-114 is a production failure, its only production line in Kazakhstan closed. Tu-204 was marketing and operating failure no one bought it so the improvement work on it was very low. Il-112 is a failure but since they really need it as a main light cargo they will put money on it. Ms-21 was supposed to have plenty of western tech which gave it some chances to be a success but now they need to replace everything.

    In modern days having an accident can destroy the project. Ssj-100 after the burning aircraft was done. Boeing 737Max after the crashes was done. Il-112 burning in the air is a very bad sign about any bigger turboprop with the same 4 engines.

    Jacques Chirac said once, addressing Poland, that it wasted a good chance to stay quiet.
    Seems that it can be readdressed towards our 1:144 scale Napoleon Laughing

    lol1 lol1

    Enlight me then... which russian, and not soviet, plane was successfully created in the last 30 years ?

    None if we forget fighters. But even in fighters they aren't making anything really new if we forget the su-57. They just upgrade existing soviet plateforms with western technology.

    What on the sukhoi series has any western technology?

    The Irbis is PESA, and the west completely skipped that chapter

    The weaponry is Russian, the engines are Russian

    As for new planes we talk about su34, su35, su30, and su57

    If the F15EX can be considered new then we must use the same approach for sukhoi

    And we can also make the same comparison between Rafale and Eurofighter
