The 40CTC (40 mm Cased Telescoped Cannon) is a 40 mm autocannon and the central component of the Franco-British 40CTAS (40 mm Cased Telescoped Armament System) developed by CTA International. It is designed to fire 40mm telescoped ammunition.[2] This format provides significant benefit within vehicles in the space envelope required for the gun and the ammunition storage.[3] However, the selection of the unfielded, thus unproven, new design for major French and British programmes was controversial.[4][5]

The 40CTAS has been ordered by the French Army for use on its future EBRC Jaguar armoured reconnaissance vehicle. The latter entered service in February 2022. It has also been mandated for the UK Ajax (formerly FRES SV) and (cancelled) Warrior Capability Sustainment Programme (WCSP) programmes.

In February 2010, CTA International signed a £11m contract with the French and British defence ministries to qualify the 40CT; this included environmental testing and the firing of 15,000 rounds.[6] The company has confirmed that the ammunition for the British weapons will be assembled by BAE Systems at the ROF Glascoed facility.[7]
