Something you don’t see too often.
Filmed from inside the bomb bay of a Russian Air Force Tu-160 Blackjack, the video below, released by the Russian MoD, shows the strategic bomber launching what appear to be a KH-555 air-launched cruise missile.
The KH-555 is a conventionally armed variant, with an improved guidance system and warhead, of the KH-55 (NATO reporting name AS-15 “Kent”), a cruise missile with a range of up to 2,500 km (1,350 nm) (and ability to carry nuclear warheads).
