China North Industries Corporation (NORINCO) has revealed that it has developed and tested a 40 mm case telescoped weapon system (CTWS) and its initial suite of ammunition.

At this stage it is unclear as to whether this has been developed to meet the potential requirements of the People's Liberation Army, or to meet those of export customers.

The CTWS has an adjustable cyclic rate of fire of between 100 and 200 rounds per minute, according to NORINCO.

So far, two natures of 40 mm ammunition have been developed for the system. The first of these is the 40 mm high-explosive (HE) round, that is designated CS/BTE3 and has a muzzle velocity of 1,000 m/s.

The second is the 40 mm armour-piercing fin-stabilised discarding sabot (APFSDS), which is designated CS/BAA3. This has a muzzle velocity of 1,450 m/s, and it is claimed that it will penetrate 130 mm of rolled homogenous armour at a range of 1,000 m.

It is assumed that there are training natures of 40 mm HE and APFSDS rounds also.

The Case Telescoped Armament System (CTAS) is fitted with a muzzle brake and a sleeve to support the barrel in a similar manner to that used for the 30 mm Mauser cannon installed in a remote-controlled turret (RCT) fitted to the German Puma armoured infantry fighting vehicle (IFV).

This Chinese CTAS has been installed in a large RCT fitted to a NORINCO VP10 8x8 armoured personnel carrier (APC). This RCT is also armed with a 7.62 mm co-axial machine gun (MG) and banks of 76 mm electrically operated grenade launchers.

Mounted to the left of the 40 mm CTAS is a stabilised sighting system that includes day/thermal channels and a laser rangefinder. An additional roof-mounted stabilised sighting system also offers the same capability.

This indicates that the 40 mm CTAS can be laid onto the target by the commander or gunner with the former capable of carrying out a hunter/killer mode of operation.
