The 40 mm Cased Telescoped Weapon System (CTWS) has been dimensioned to provide overmatch against urban, dismounted troop and armour threats beyond 2035. The versitility of the system enables it to provide an effective lethality solution for infantry fighting, reconaissance and peacekeeping missions.

The weapon system is comprised of an externally powered cannon and a link-less feed magazine. The cased telescoped ammunition shape simplifies the cannon design bringing benefits in terms of cost, maintainability and compactness. The turret intrusion of the 40mm CTWS is similar to that of a conventional 25mm cannon. The system design allows it to be operated by a single person, loading and unloading the magazine, firing under power and all reversionary modes. The cannon can be integrated into new or retrofitted onto existing platforms from 8 tonnes upwards.

M i s s io n A range of ammunition types are provided for CTWS. They offer solutions for land service applications for troop suppression, anti armour and airbourne threats.

C h a ra c t e r i st i c s The ammunition is of a novel design with the projectile completely surrounded by propellant and enclosed within the cartridge case. This means that the ammunition volume is reduced for a given performance level. The resulting ammunition is cylindrical in shape facilitating the novel design of the compact cannon and associated feed system. The size of the ammunition is 255mm x 65mm, calibre 40mm.

An electronic timer module is added to the standard PD fuze to provide the airbust function of the AB ammunition. The AB fuze is programmed during the round chambering phase by induction.

WARRIOR turret 40 C TA M a n n e d Tu r r e t f o r WA RR I O R I FV u p g ra d e The turret has been designed to interface to the Warrior IFV chassis without modification. It provides a compact two-man solution, which is fully stabilised to allow fire-on-the-move capability.

Careful design has resulted in the gunner having the ability to re-load and manage the weapon single-handedly. Both the gunner and the commander have the ability to aim and fire the system from their respective crew positions positions. The objectives for the mechanical design of this turret were to provide a minimum cost solution whilst observing the following principal requirements: • To respect the existing Warrior IFV interfaces principally turret ring, slip ring and deck swept clearance

• To provide a good base level of ballistic protection to the crew and its equipment with the possibility to upgrade this with “add-on” protection or HK-DAS as required • To provide a stabilised main armament • To respect the ergonomic requirements of a manned turret system and head out operation • To facilitate the integration of the BGTI sighting system • To integrate the BOWMAN/ P-BISA system • Built on an Open Electronic System Architecture • Respect prevailing safety standards

TOUTATIS turret 40 C TA U n m a n n e d Tu r r e t The French Government (DGA) has contracted CTAI to develop and produce an unmanned turret, integrating CTWS. The turret has been designed to be lightweight and low profile to maximise the survivability, mobility and transportability of the host platform. Principal requirements for the turret design: • Integrate the 40mm CTWS with a triple nature magazine and up to 60 on-line munitions • Minimise turret weight (under 1.5 tonnes) • Maximise stealth • Provide a base level of ballistic protection to NATO Level 3 (7.62mm AP) for turret mounted equipment, with the option to increase this with “add-on” armour protection or HK-DAS as required • Provide the crew with observation capability in order to engage targets whilst on the move • Provide a fully stabilised 40 CTWS main armament • High elevation weapon angle for urban and arial targets (-15° to +65°)

The crew are housed within the chassis offering them increased protection. Situational awareness is provided by TFT display screens giving the crew a 120° observation arc. Both commander and gunner can operate the turret in ‘hunter-killer’ mode using the two fully stabilised panoramic sights and the stabilised weapon system.

In order to reduce integration cost and complexity whilst allowing future upgrade options, the electronic design is based on an Open Electronic System Architecture. The unmanned turret will be suitable for all types of programmes requiring: • Low turret intrusion into the platform • Compact turret size • Lightweight turret • Simple adaptation to a specific chassis

CTWS F e e d S y st e m The feed system supplies ammunition to the cannon. Ammunition natures can be contained in single or multiple magazines according to customer requirements. The CTWS link-less concept allows the feed system to be adapted to different platforms. The feeder is an automated system providing rapid switching of ammunition nature and supporting high rates of fire. • Round selection < 3s (dual system) • Round selected is the round fired under all conditions.

Retrofit C T WS I n t e g ra t io n The CTWS is a “drop-in” weapon system solution which can be retrofitted into existing or integrated into future land, sea and air platforms. The systems principle elements are weapon, feeder and cannon control unit. The principal system elements include the weapon, feed system and control unit.

C T WS Tu r r e t I n t r u s io n The CTWS with its “push through” weapon firing cycle simplifies turret integration; the compact design provides optimum ammunition stowage, high angles of elevation and minimum turret intrusion.

C T WS Pl a t f o r m s The CTWS has already been demonstrated in a range of platforms. These manned and unmanned environments have been used to undertake integration assessments and a variety system risk reduction work.

The high system lethality combined with a low integration burden means that CTWS offers the highest level of stowed kills of any comparable medium calibre weapon system.
