CTA International (CTAI), a joint venture between Nexter Systems and BAE Systems Global Combat Systems is to complete qualification of its CTAS (Cased Telescoped Armament System) 40mm weapon system by mid 2013.
The system is currently being trialed at French procurement agency DGA (Direction Générale de l’Armement) Land Systems facility of Bourges, France.
It comprise elements such as the canon, ammunition handling system, controller, elevation and azimuth drive motors from MOOG, encoders, gyroscopes and accelerometers, electronic control unit from Ultra Electronics, power and control cables and the gun mount.
The ammunition range comprises APFSDS-T (Armour Piercing Fin Stabilised Discarding Sabot-Tracer), GPR-PD-T (General Purpose Round-Point Detonating-Tracer), GPR-AB-T (General Purpose Round-Air Burst-Tracer), TP-T (Target Practice-Tracer) and TPRR (Target Practice Reduced Range) rounds.
CTAS was selected by the UK´s Ministry of Defence materiel organization DE&S (Defence Equipment & Support) to equip British Army´s General Dynamics European Land Systems ASCOD SV Scout vehicles procured to General Dynamics UK Ltd as part of its FRES (Future Rapid Effect System) programme and as well 380 Warrior tracked armoured infantry fighting vehicles to be upgraded by Lockheed Martin UK Ltd and its partners to the WCSP (Warrior Capability Sustainment Programme) configuration. It will also fit the T40 turret for the future French Army´s 292 EBRC (Engin Blindé de Reconnaissance et de Combat) combat reece armoured vehicles which is a programme part of SCORPION (Synergie du COntact Renforcé par la Polyvalence et I’InfovalorisatiON) modernization programme. EBRC is intended to replace in service AMX-10 RCR and ERC-90 Sagaie wheeled combat vehicles.
The CV21 family of lightweight tracked armoured vehicles recently unveiled by BAE Systems Global Combat Systems includes a reconnaissance variant equipped with a turret which could be armed with the CTAS system.
Thales propose a truck mounted self-propelled anti-aircraft gun system (SPAAG) which comprises a modified version of CTAS´ 40mm cannon installed on a 6×6 chassis truck mounted turret. The turret includes as well a fire control suite. In 2010, Thales unveiled the MGS (Gun Missile System) mobile air defence system concept which feature a turret mounted in wheeled or tracked armoured vehicle, armed with six ready-to-fire Starstreak short-range surface-to-air high-velocity missiles, the 40mm gun and a multi-sensor fire control package combining a tracking radar, gyro-stabilized sensor head and fire control computer systems. Both systems can be linked to Thales Air Systems Ground Master 60 (GM 60) ground based mobile search radar.
