Textron (Avco) BLU-106/B BKEP

The BLU-106/B BKEP (Boosted Kinetic Energy Penetrator) was a rocket-boosted submunition against runways and hardened aircraft shelters. It was developed by Avco (now Textron Systems) in the mid-1980s under a U.S. Air Force contract. The BLU-106/B was intended to be delivered by the following weapons:

After release from the dispenser, each BKEP projectile was retarded by a parachute until a 65° nose-down attitude was reached. Then the parachute was discarded, and the solid-fueled rocket motor ignited to accelerate the projectile to high speed. In flight, the BLU-106/B was stabilized by four flip-out tailfins. The BKEP's high-explosive warhead detonated after the weapon had penetrated the target surface.

In the end, the BLU-106/B submunition, and the weapons that were designed to carry it, were not produced for service use. Reasons included relatively high cost, and the development of other weapons, which could satisfy the operational requirement (e.g. the 900 kg (2000 lb) BLU-109/B penetrator warhead).
