KAB-500KR

The KAB-500Kr[1][2] (Correctable air bomb - 500 kg) is an electro-optical TV-guided fire and forget bomb developed by the Soviet Air Force in the 1980s.

The seeker employs a gimballed daylight television imaging sensor under a wide angle glass dome.

Unlike the earlier US GBU-8 HOBOS and AGM-65 Maverick which employed contrast lock technology, the -Kr series guidance system employs Scene Matching Area Correlation technology more akin to the US Navy DAMASK seeker or Tomahawk DSMAC.

The bomb is 305 cm (10 ft) long and weighs 520 kg (1,150 lb), of which 380 kg (840 lb) is a hardened, armor-piercing warhead capable of penetrating up to 1.5 metres (5 ft) of reinforced concrete.

The weapon's seeker can lock onto a target at ranges of up to 15 to 17 km (9.3 to 10.6 mi), depending on visibility.
