What was the price of mig 23 in the 80s ?
And the price of a F16 in the 80s

MiG-23: 2 – 2.5 million rubles
export price – 3.6 – 6 million $.

Thx. So can they actual have some improvements on the IR spectrum?

No

Not that it matter but I will have to let you know that PAK-FA is actually bigger than F-22, and both of them are alot bigger than the F-35

area of this projection:
Su-27 – 10 m2
T-50 – 9.47 m2
F-22 – 9.25 m2
F-35A – 8.12 m2
F-35B – 8.36 m2

the difference between the T-50 and F-22 is negligible

The first MiG-29 variant did not fulfill Soviet requirements. These stated a range of 800 kms with internal fuel and 2.750 at high altitude with a drop tank. The first version (9.12) managed 700 and 2.100 respectively.

MiG-29 (9.12)
range without external tanks (3300 kg of fuel):
low hight of M = 0.5 – 710 km.
at an altitude of 1430 km
with a single external tank (3300 kg + 1175 kg)
flight height of 13 km, M = 0.8 – 2100 km

Do you have serials of this mysterious air frame or Pravda forgot to mention such unimportant detail???

A search operation was widely reported in the Soviet press and on television. The divers told a lot of interesting details. A few broken planes, a large number of shoes with the connected laces in place KAL007. Many such “truthful Western media” will never tell

Третий день означает 13 сентября…
Такой тип стержней является важным структурным элементом любого самолета с изменяемой геометрией крыла, которая используется только на сверхзвуковых самолетах. Остов, с которым работал флот принадлежал, вероятно, EF-111, который военно-воздушные силы США использовали в качестве самолета радиоэлектронной борьбы.

The third day means on September 13…
This type of rods is an important structural element of an aircraft with variable geometry wings, which is only used on supersonic aircraft. Frame, worked with the Navy belonged, probably, EF-111, which air force the United States used as electronic warfare aircraft.

During KAL 007 searches in the territorial waters of the USSR was found F-111 crashed. Maybe this is it.
