So how many more PAK-FA T-50 prototypes will fly before we start to see series production starting?

Pratt & Whitney is producing a new variant of the TJ-150 engine for Spear.

Strange that Pratt & Whitney are producing an jet engine for Spear 3, I would have thought that Rolls Royce would have been considered for the design.

Any word on how many Spear 3s the UK will purchase? I am glad that the UK has gone with the Spear 3.

No doubt it will be a very interesting program, I for one cannot wait for it.

Supposedly T-50 has done testfire of a missile from internal bay.

Source, listening to the interview now; http://radiovesti.ru/audio/253/242.mp3

The interview is with Mikhailov, VVS commander between 2002 and 2007. Yes, he is the one that made the infamous “Mach 2.15 reduction to Mach 2” quote re T-50. He mentioned the testfiring happened “day before last” (@17.30min) ie on 16’th. What frame i wonder, T-50-3, -4 or 5R? 😀 The man has 4000+ hours in Su-7/MiG-21 alone; it is a miracle he is still alive…

What sort of missile was it that the PAK-FA launched? R-73 or R-77? Great news for the PAK-FA program.

An interesting picture MSphere, I did not know that the Germans had that capability for their Tornadoes.

I like the B-21 designation, at least it was not going to be B-3.

Quite right too. As I shall be doing shortly with my copy of Ace of Spades.
