40CTAS (CASED TELESCOPED ARMAMENT SYSTEM)

THE WORLD’S MOST POWERFUL AND COMPACT NATO QUALIFIED MEDIUM-CALIBRE WEAPON SYSTEM

The 40CTAS is a modular weapon package which includes:

Innovation

The key feature that defines the “Telescoped” technology and differentiates it from conventional medium caliber weapons is that the projectile is located inside the cartridge case and is surrounded by propellant powder. Compared to a conventional cartridge, the ammunition is more compact and its length is reduced, optimising the kinematics of the weapon, the storage volume in the vehicle and logistics.

The cylindrical profile of the ammunition removes the needs for extraction of empty cartridge cases, which are instead ”pushed-through” and ejected perpendicular to the axis of fire. New ammunition loaded into the chamber pushes out the previous empty cartridge case.

With the 40CTAS, the axis of ammunition introduction is the same as the axis of elevation. This enables ammunition to be introduced into the chamber along the feeding axis regardless of the elevation angle of the barrel. This removes the need for flexible ammunition chutes found in conventional weapons, which are not an efficient use of space and are prone to jamming. As a result, the feeding mechanism is completely static compared to the turret structure and allows easier firing on-the-move operations and a significant improvement in weapon reliability.

The Ammunition Handling System (AHS) makes it possible to accommodate all types of ammunition in the same load and to quickly switch from one nature to the other depending on the threat. The ratio of the different types is also adjustable according to each mission.

Discover the 40CTAS

For more than 25 years CTA INTERNATIONAL is the Design Authority of the 40CTAS weapon system. It provides to the end-user enhanced lethality and superior fire power over any other medium calibre system. Discover the key components of the 40CTAS.
Capable of firing
at higher elevation,
giving more target flexibility.
Takes fewer rounds to do the same job.
Saves space inside the vehicle,
leaving more room for equipment and crew.
Can be retrofitted into existing vehicles,
providing a quick and efficient upgrade.

Performance

With its compact, versatile Cased Telescoped design, the 40CTAS enables the agility and mobility needed for critical missions, without compromising on firepower. Thanks to its compact size, the system is easily adaptable to any type of turret, either land or naval, manned or unmanned. It is compatible with small race-ring diameters. The low turret intrusion enabled by the ‘push-through’ architecture allows extremely high elevation angles up to 75°.

The 40CTAS achieves a 4km+ operational range while delivering unmatched armour penetration for a medium-calibre weapon. The terminal effect of the 40mm HE round is 4 times greater than that of a 30 mm conventional High Explosive round. The 40CTAS ammunition can address land, naval and aerial targets including emerging drone threats.

The 40CTAS has a rate of fire up to 200 rounds per minute and include a high accuracy mode compatible with coincidence firing system.

Entering in service

600 CT have been manufactured so far. The 40CT/CTAS are being introduced into the armed forces of 3 NATO users.

CTAS are integrated on the following platforms:

Jaguar

Rapid fire

Ajax

A weapon system tailored to your requirements

Following years of experience dealing with all types of integration challenges, we recognise the need to provide customised packages that guarantee you a complete system in a shorter timeframe.

We’ve structured our 40CTAS offering into four configurations, from the simplest cannon module to our full system, including fire control system. Which fit is perfect for your requirements?
