Description: The CTWS (Case Telescoped Weapon System) gun, formerly known as the 40 CTA, is being designed to fire 40mm telescoped - the projectile inside its case for volumetric savings - ammunition. It is a really compact gun suitable for armored vehicles conceived for reconnaissance and fire support missions. The Anglo-French CTWS gun will be available for future ground combat vehicles and/or current vehicles under modernization programs. CTA International (CTAI) is the joint venture between BAE Systems and French GIAT Industries which is responsible for CTWS gun development. As of June 2016, the CT40 cannon has been selected for the British Army Warrior and Ajax armored vehicles and the French Army Jaguar armored vehicle.

On June 16, 2004, the UK MoD awarded BAe Systems a £6 million ($10 million) contract for a manned turret integration program that will end in 2006. The CTWS gun will be integrated into a two-man crew turret upon the Warrior infantry fighting vehicle. The French MoD awarded a similar contract in November 2003 for integration of CTA gun into an unmanned turret (Toutatis program). The data collected during these two programs will help to risk reduction of Warrior Lethality Improvement Programme (WLIP) and other programs such as UK FRES, and France's ERBC and VBCI. In June 2006, BAE System announced that the CTWS weapon system was included into its proposal for the Warrior armored vehicle modernization program.

The CT40 cannon can fire four types of ammunition: point detonating round, armor piercing round, airburst round and aerial airburst round. The point detonating round is intended against hardened targets, has a muzzle velocity of 1,000 per second and can pierce up to 210mm of reinforced concrete. The armor piercing rounds is intended against tanks with a muzzle velocity of 1,500 meters per second and a piercing in armor (hardened steel) of up to 140mm. The airburst round is intended for multiple soft skinned targets such as personnel and vehicles. It has maximum muzzle speed of 1,000 meters per second and can hit targets distributed over an area of 125 square meters. The aerial airburst round is intended against drones, helicopters and light aircraft. Each round carries 200 tungsten pellets, a muzzle velocity of 900 meters per second and a maximum range of 4,000 meters.
