BUT it can outrun and out-manoeuvre them, as the footage of the failed engagement against it by Patriots clearly show.
The point is that very few aircraft are able to pull heavy g turns while loaded with heavy air to ground ordinance loads and full fuel loads, so increasing the structural strength of an aircraft to allow better manouver performance will increase the dry weight of the aircraft and reduce fuel and payload weight performance.
So both manoeuvrability, acceleration and climbing rate matter there, just they have to be all raised at the same time, not one at the expense of others.
They matter only when you are aware you are under attack and what the incoming missile is doing... but if you are aware of an attack and what the incoming missile is doing then the manouvers do not require Mig-29OVT levels of manouverability.
There are documented footage Su-34 losses.
I am not saying none have been lost, I am saying the losses were mostly necessary and pussies need to accept there are losses in war instead of falling to pieces and claiming this or that design must be crap of aircraft are being shot down.
Of course aircraft can dodge missiles. That is why there are missile evading maneuvers.
Missiles move at very high speed and are more like bullets than other aircraft and if you have information about an incoming bullet you can avoid it being able to hit you by moving in very specific ways that ensure it is unable to match your movements and end up hitting you, but that is not the same as being able to dodge bullets.
Modern Russian and Soviet missile often had directional fragmentation warheads when meant even if the missile didn't hit you directly it could still destroy the target it was after by directing the fragments from its warhead at the location of the target when it exploded.
The hollywood bullshit of "dodging" missiles is ridiculous, but widely believed...
A improved ground attack Su-57 version with increased stealth should probably be the future.
Personally I think an enlarged Su-57 would make sense but I suspect equally a reduced size PAK DA might also be considered too.
The PAK DA is to replace the Bear in the subsonic strategic role, but also the Tu-22M3 in the theatre bomber role, which would be rather more effective now with the introduction of glide kits for dumb bombs... in fact I would wager that either the bomb bay of the PAK DA has been modified or they are going to have special glide kits that can be attached and fit internally on bombs in the PAK DA for the purpose of allowing large amounts of bombs to be carried with glide kits attached.
A high altitude stealth flying wing with self defence AAMs might make a strike model of the Su-57 redundant... the core problem being carrying large amounts of conventional ordinance internally is going to make the aircraft very big very quickly, which means more internal fuel which makes the problem worse.
I rather think an enlarged Su-57 might be a good aircraft for carrying larger numbers of long range missiles internally... perhaps less emphasis on manouver performance and have extra weapon bays... at the moment they have two large weapon bays between the engines... perhaps a longer airframe and make those weapon bays longer, but also extend the thickness of the fuselage out past the engine bays and put internal weapon bays on the outside of the engine bays as well... so from wingtip you have the wing, with external weapon positions used when stealth is not critical, and then you have two weapon bays, one in front of the other, then an engine naccelle, and then the two centreline weapon bays of extended length, and then the other engine naccelle and then two more weapon bays and then the wing...
They could replace the current engines with the engines being used on the Tu-160M... they could make it into a delta wing design with no tail surfaces.
But then I suspect the PAK DA might make a more suitable design even if they scale it down and use the new engines for the Su-57 in a reduced size model for shorter range missions.
They are currently spoiled for choice and have a lot of excellent aircraft types available to them... perhaps the final choice will be a scaled up S-70 drone with two engines as a longer range strike... perhaps 50 ton MTOW...
The fact is that the missions the Su-34 flys are the most dangerous any aircraft can fly... you are flying into an enemy air defence network to take down targets... they can let you fly through a dozen times and then set up an ambush, or they can try to shoot you down every time...
