Originally known as the LAAAS (Low-Altitude Airfield Attack System), the JP233 is a British submunition delivery system consisting of large dispenser pods carrying several hundred submunitions designed to attack runways.
Development of the system began in 1977 as a 50/50 cooperative program between Hunting Engineering (now known as INSYS) of the UK and the US Air Force. The USAF intended to use the weapon with its FB-111 strike aircraft; however, in 1982 rising costs led them to pull out of the programme, and the British completed development on their own for potential use with the Tornado, Jaguar and Harrier.
