    They have other aircraft they use as testbeds Su-30, SU-27 and few other, even bort numbers are known. I never tho heard of that prototype flying before as testbed or anything. I mean, maybe it did, i just never heard of it.

    No, MiG 1.44 made only two very short flights in 2000, with private money from MiG, and never again. Su-47 (S-37) is the one which has made many flights recently, especially testing the weapons bay for the T-50.

    Now you say it VSTOL is actually like a walking dead that resists dying and keeps infecting innocent aircraft projects. That thing you posted below could have been, as the F-35, a decent plane without that requirement, you are aware aren't you? Look to the engine size of this plane and tell me how to make something out of that internal distribution that wouldn't look like a huge paunchy frog:

    Whether the LMFS will have S-ducts this will determine if the Su-57 suffers in stealth from the lack of them. If the lack of S-ducts made the stealth of the Su-57 unacceptably worse, then MiG learned that and its reasonable to assume that they will patch things up.

    Thanks for the clean-up Isos  thumbsup

    I know it has blockers. Just wanted to point out that it would be very illogical from Sukhoi to design a LO plane and then not take the engines into account...

    A future LO fighter design would have essentially the same scientific and technological background that the PAK-FA had, so I doubt they would come to contradictory technical solutions

    The X-32 looks like the old F-8 Crusader after a face-lift.

    Sorry to say that, but i think Russia will skip the manned LMFS and go for combat drones in that size and weight category.

    You are damn right, look below: the "proposed" production version would not have been such an aesthetic outrage. The weird chin intake, as well as the thick belly, was necessary due to the engine being placed immediately after the cockpit in order to satisfy those absurd STOVL requirements (are you reading Gunship? Very Happy)

    It still intrigues me how they planned to manage the boundary layer in that intake though...

    I tend to agree with you regarding the manned/unmanned thing, the VVS seems very satisfied with the Sukhois to go for light fighters other than to support MiG IMHO. Even when the LMFS could be a good idea, it will be very expensive to develop and the economic advantages against heavy fighters arguable given the relevance of avionics and LO in the cost of modern fighters. An ever hypothetical "export market potential" may be not enough to trigger the development.

    For certain roles like observation and patrol a UAV is fine.

    Even for striking targets of opportunity with a UCAV make sense because if you see something worth killing the time to get an attack aircraft into the air and to the target area means the target might have left the area and opportunity missed.

    And really the deep strike in enemy controlled territory is already performed by the cruise missile and to a degree the long, medium, and short range interception role can be taken by unmanned vehicles called SAMs... but today and for the near future I see no practical UAV fighter option....

    That suggests that there will be a position for a light stealthy numbers fighter... it might operate with some drones that follow it around and carry extra weapons or defensive equipment, but you still need that man in the cockpit.

    Likely the drones will be unmanned versions of the 5th gen fighter anyway...

    Lighter smaller but still capable 5th gen fighters make sense for carriers, and simply to fill the gaps.

    The old maths of if one Flanker has twice the range it can cover twice the area of a Fulcrum is not true... the logic that 8 Flankers can cover the same area as 16 Fulcrums yet are not twice as expensive doesn't work because they have very similar flight speeds... having half as many flankers just means operationally bigger gaps between airfields... not so important in Siberia because that is unavoidable, but in western european Russia it means big gaps with no planes to fill. The Flankers could get there if they needed but it would take twice as long for the Flankers to fill those gaps because they would be taking off from further away.

    For a given area two Fulcrums offer better coverage than one Flanker.

    It is the same for 5th gen fighters... NATO attacks will concentrate on the airfields, so having fewer airfields is a bad thing... cruise missile and bomber attacks on targets in Russia will conversely bypass airfields and major SAM sites... so again, the more airfields you have with planes on them the better dispersed you are.

    The Russians are not stupid... they know the game and would disperse their aircraft to minor fields at the start of hostilities... spreading twice as many smaller fighters makes sense... especially when ground radar and airborne radar will enhance the radar information picture of all aircraft, so the radar size on you aircraft is not so important... especially when carrying the same weapon at the same speed and altitude...

    Agree your reasoning regarding UAVs, but I guess the question is, when a machine can independently perform the tasks of a human with enough efficiency, flexibility and reliability to let it tackle a mission without a man in the loop? This may come so soon (at least from a purely technical point of view) that many wouldn't believe it. Probably only thing missing now is training the machines, little more than that. Policies of military are another issue...

    Even when I am all for the 5th gen light Russian fighter, costs come again as a most pressing issue limiting your proposal. Your reasoning is again true but: do you think this project will be undertaken or not? For this to happen, the cost advantage of the plane (procurement + operation) times the amount of units produced + net export profit - cost development must be bigger than zero when compared to existing heavy fighters. Since the Russian air force is not that big and cannot count on many orders by means of political influence the project risk is quite big IMHO...

    LMFS: Russia has th third biggest air force in the world, only counting the planes. So it is big.

    GarryB: Because of these facts (2 planes are better than one) i think that Russia will buy a few MiG-35´s in the next years. All big air forces (Amiland, China, India) got a mix of heavy and light planes, Russia will not be the exception.

    Regarding UCAV´s as fighters, that concept is feasible, even today. Think of them as flying air defence systems. Instead of sitting on the ground, your radar and launcher are in the air.

    Yes, but is it big enough? The new project needs to pay out, and the numbers are already bleak for the PAK-FA, imagine adding an additional plane to the equation. The shared developmental costs per plane are very big. Even when many of the systems and technologies could be recycled from PAK-FA, it is a different plane with a completely new testing process. Don't get me wrong, I would love to see that but I also want to be realistic.

    May I ask why not? How big are the expected savings derived from using a light fighter instead a heavy one?

    Savings are pretty substantial if light plane is single-engine one.

    MiG-35 is not.

    Keep in mind the huge number of air defense systems in russian service. Each army brigade in Russia has air defence systems combarable in strength to a whole fighter wing in the west. The land based systems can be reloaded faster and can work 24/7.

    A heavy plane has its advantages. More fuel (larger radius of action). Greater combat load. Larger radar (which can mean a larger detection range). But a lighter plane is mostly cheaper to use. For some missions they are better.

    The mix in Russia will propably be 80% heavy and 20% light. A regiment of lighter planes per regional command for air defence above the front and attack missions.

    The MiG-35 will be an stopgap measure until the combat UCAV´s like the Okhotnik (Sukhoi, 20 tons) are ready.

    Agree on the single engine issue, but do you have a figure or an estimation of those substantial savings? Also don't expect MiG-35 to be much cheaper to procure or operate than a heavy fighter.

    Again, MiG-35 is closest to light fighter they have. Here Hole comments 80-20 for heavy-light fighters. This is clearly what is expected in coming years since they will buy the -35, but is that the force structure the VVS would freely choose if they could? With those numbers you cannot economically develop a new single engine fighter.

    Agree, it will develop similar to what you say IMHO.

    Maybe mixed regiments of heavy and light fighters would make for reasonable savings without the lighter fighters being dragged by shorter range radars or simpler avionics, since they would operate supported by the bigger ones.

    A regiment (20 - 30) of light multi-role fighters per regional command should be enough. They will beu supplemented by more and more drones, first and foremost as bombers and in CAS/attack roles, later also as interceptors.

    +100 Light fighters are more destined for defense. Can do the same but just range is smaller. I am sure LMFS will be created. It is logical step. Not only TuAF but also navy (CVN) and export

    taking account present state of autonomous vehicles (ok for military is a step ahead but still way to go) no way you can build autonomous fighter yet.

    Who talks about autonomous? Flying air defence system with a controller on the ground. Just like any other drone, but with radar and a few AAM´s.

    By the way... the S-400 can operate quasi autonomous. The radars can locate and track targets alone, all you need is someone to push the button to launch a missile.

    I think it´s to late for a manned LMFS. Why build a manned plane when you got a drone in the same weight category ready for testing? In the air defence part there are already enough planes: modernised Su-27´s and MiG-31´s, Su-30, Su-35, soon the Su-57 and the MiG-35.

    for some strange reasons nobody didnt do it yet. Technology for remote control exists already for some time. There must be the reason isnt it?

    MiG-31 - has ~ 10 years before getting retired. MiG-35 is only a stopgap for LMFS and 24 is not really the big number. Just to give MiG something to work on and potentially export contracts. . All Su-27/Mig-29 will be gradually phased out withing next 6-8 years.

    Besides you wont export drones on that level to poor countries using still MiGs-21 or F-5 and this could offset investment costs. Perhaps drone and manned mode but we'll need live to see it.
