BL755 is a cluster bomb developed by Hunting Aircraft that contains 147 parachute-retarded high explosive anti-tank (HEAT) submunitions. Its primary targets are armoured vehicles and tanks with secondary soft target (anti personnel) capabilities. It entered service with the Royal Air Force (RAF) in 1973. As part of the 2007 Convention on Cluster Munitions negotiations, the RAF agreed to remove the BL755 from its inventory by 2008. Its role has been replaced by the CRV7, an air-to-ground rocket with such improved performance that it is effective even in the face of the ZSU.
