Fuel T-50 8700 kg

how did you calculate volume if you even don’t have cross-sections? asking because your final figure is not correct

I’m not sure if they have heard something about idea of weapon bays internal fuel tanks at Sukhoi

of course, idea of building stealth fighter with internal weapon bays to put tanks there instead of weapons to increase range may look attractive so some…

yes, Bogdan said exactly that

This is not an official data, whereas the 38t came from USAF official web, which means there must be 4 DTs.

Oh, the same site was saying something totally untrue about F-22 emty weight for ages.
I will stay corrected when you will show me at least one photo of F-22 flying with four DT.
Obviously, such a configuration would be flown during tests a while ago. One problem – no one saw it. Evar.
14 years after first flight.

Davidenko, that’s first
second, I never heard him saying this figure for F-22 RCS
RCS can’t be described by one figure. frontal RCS?
third, I give no fu*k for what Indian press is saying of T-50 RCS as they don’t know anything about it

Is this the first published dimensions of PAK FA ????

they are taken from web and not official (later are still classified)
not a guess

KnAAPO+NAPO are proposed cooperation chain in future T-50 production.
NAPO=forward fuselage, empennage, may be more
Tail surfaces for T50-1 – T50-3 were made at VASO with their final assembly made at NAPO for KnAAPO. Seems that currently NAPO is not ready for something more advanced. But it should as KnAAPO is overloaded by current and incoming job.
