Mikoyan MiG-25 "FOXBAT"

[A12]

''The MiG-25BM could carry up to four anti-radar missiles under its wings (only two missiles were planned during the design phase) or a combination of missiles and bombs (up to eight FAB-500M-62AT bombs). The "Foxbat-F" carried the Kh-58U variant of the "Kilter." It was built primarily of titanium and was designed to resist kinetic heating of 400 to 500°C. The maximum Mach number with missiles was restricted to 2.38.''

So ,with the four 650 kg heavy ( 150 kg warhead only ),MiG-25BM could reach about 2600km/h and it's amazing ,when we know that those ARM's were not attached under the fuselage but under the wings ( in terms of the huge aerodynamic drag).

M=2.35 with 4 Kh-58U - at minimum afterburner in cruising mode. M=2.38 - limitation due to heating of the missile equipment in long duration flight.
