The modernization of the MiG-31 will end in 2018. This is the end of history Foxhound.
IMHO, will be held modernization and will be released on the Su-34M, a new electronics, possible weapons bay, armor. Soon will fly Russian X-47. Be sure to make the PAK-DP, that’s for sure.

Russians are bombing all fractions fighting against Syrian regime.. as they are mandated..

Allah will understand who is the terrorist and who is a “moderate terrorist”

Where are the figures I have said repeatedly.
The answer is very simple, do not compare the incomparable. PAK FA fifth-generation fighter, the Rafale – 4.5. In these planes only the price of the same. :p

What are the numbers? 9.47 m2 and 8.12 m2 – front area. Diameter = 2 * √ (9.47 m2 : π)

So what? Take 2 Aircraft with the same cross section, one flying wing design, one F-106 design, you think they’re gonna have the same transsonic/supersonic performances?

Elongation – that’s what matters.
T-50: 9.47 m2 a circle diameter of 3.47 m, 20 m: 3.47 m = 5.76
F-35: 8.12 m2 a circle diameter of 3.21 m, 14 m: 3.21 m = 4.36

5.76: 4.36 = 1.32 or 32%

What’s at the Y axis ? Frequency ?

P(обнаружения) – “вероятность обнаружения” – probability of detection, IMHO

Detecting and tracking the SR-71 is not difficult for the Soviet anti-air defense. I’ve heard about it many times during my service on the destroyer (1989 – 1990 year).
Score RCS – 6.8 m2

So the J-20 has its CoP behind its CoG?
