I thought the R-77Ms and R-37Ms were already tested on the Su-57 around 2014-16. Is those missiles having teething problems one of the reasons the production date l of the Su-57 has been pushed back multiple times?
Even if the Su-57 never carries either missile in combat it would not effect its production.
The Su-57 is a stealth aircraft hunter, so it will likely carry R-77Ms because of their better radar sensitivity... besides who knows what missiles they are carrying at any time... what makes you think there are any teething problems with either missile?
It's quite secret but both must have had delays or don't fit with the optimistics planed schedule like any big project.
I have not read anywhere about problems with either missile... the R-37M is in operational service with MiG-31s which will be its primary user...
So when it comes into service around 2021, its primary stealthy AA and AS armament wont be available? If it has to do air superiority it will be unstealthy?
What makes you think the R-77M is not ready for service?
If they are testing performance in Syria for an air to surface missile then it is in service... they are just testing its performance on a real actual target...
This means its confirmed that the Su-57 can only carry 4 R-77s in internal bay? Thats a shame. F-22 still has more BVR ammo.
F-22 has no IRST or L band AESA antenna in its wing so when the four internal medium or long range AAMs are fired from the Su-57, the F-22 probably wont even know what is happening...
3. This may be only current capacity available to the Su-57 as for current program. Su-57M or later serial versions could very easily carry more, there is space. Very much like the F-35 only getting the ability to carry six AIM-120s later on.
This could be export configuration... for all we know they might only have two wiring points and suspension points in each bay so it is limited to two weapons.
Further development could lead to a frame that could be attached to connect the wiring for twin launch pylons for each weapon point currently in each bay, which would mean 8 weapons per bay instead of four.
But as I mentioned... the Su-57 is intended to operate with Su-35s and S-70s above S-350s, S-400s and S-500s, so carrying a few extra missiles might not be considered worth the extra weight and complication...
