The ammunition is of a novel design with the projectilecompletely 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.

Both PD and AB fuzes contain a mechanical safe and arm unit. An electronic timer module is added to the standardPD fuze to provide the airbust function of the AB ammunition.The AB fuze is programmed during the round chambering phase by induction.

Careful design has resultedin the gunner having the ability to re-load and managethe weapon single-handedly.Both the gunner and thecommander have the ability to aim and fire the system from their respective crew positions.The objectives for the mecha-nical design of this turret were to provide a minimum cost solution whilst observingthe 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 integrationof the BGTI sighting system

• To integrate the BOWMAN/P-BISA system

• Built on an Open Electronic System Architecture

• Respect prevailing safety standards

The turret has been designed to interface to the Warrior IFV chassis without modification. It provides a compacttwo-man solution, which is fully stabilised to allowfire-on-the-move capability.

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-linemunitions

• Minimise turret weight (under 1.5 tonnes)• Maximise stealth• Provide a base level of ballistic protection

to NATO Level 3 (7.62mm AP) for turretmounted equipment, with the optionto increase this with “add-on” armourprotection or HK-DAS as required

• Provide the crew with observationcapability in order to engage targets whilst on the move

• Provide a fully stabilised 40 CTWS main armament

• High elevation weapon angle for urbanand arial targets (-15° to +65°)

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

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

The feed system supplies ammunition to the cannon. Ammunition natures can be contained in singleor multiple magazines according to customerrequirements. The CTWS link-less concept allowsthe 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

to research, developand produce weapon

systems using the Cased Telescoped Ammunit ion

and gun technology,known generical ly as the

Cased Telescoped Weapon System (CTWS) .

The company is staffedby a team of 40 scient ists and engineers from the UK and France, co- located in
