RDS 40 X 53 MM HE-T

GENERAL DESCRIPTION

The cartridge 40 x 53 mm HE-T, is to be a High explosive fragmentation round with a self destruct mechanism and tracer element, designed to comply with the military specifications applicable to this kind of ammunition and for use in the 40 mm H & K GMG 40 AGL. Its primary application is for use against personnel, infrastructure and light armored vehicles.

The round will be fixed round of ammunition consisting of one-piece aluminum body or equivalent with an internally fitted steel pre-fragmented jacket containing a high explosive charge. The tracer element will be fixed at the base of the projectile body and sealed with a closing disc and ring. The projectile body should be attached onto the cartridge case assembly. The base should have a percussion primer fitted into the center of the base of the cartridge case. A propellant charge should be contained in this cartridge case.

Weapon & Link Functioning
When the 40 mm H & K GMG 40 AGL is fired at temperatures of between -20 to + 50 oC the ammunition or links shall not cause any malfunctioning of the weapon.
The type of coupling cartridge link will be M16A2. It must be stated that the linkage can be fired from the 40 mm H & K GMG 40 AGL without the ammunition or links causing any malfunctioning of the weapon.

Velocity
The mean corrected muzzle velocity of the (Vo) shall be 240+ 3.0 m/s.

Range

The maximum range of the projectile will be 2,000m (approx).

Projectile Tracer

The tracer element must burn for at least 5 secs after leaving the muzzle. Tracer brightness must be greater than 300 cd.

Danger area Template

A copy of the range danger area template of this ammunition to be submitted


Safety

The minimum arming distance for the projectile will not be less than be 18 m from the muzzle after shot initiation. All projectile must be armed by 40 m. The self-destruct capability of the projectile and neutralisation of the explosive must take place within 18 +4 sec after firing under normal conditions

Lethal Radius

The lethality danger area associated with the projectile detonating, as a result of self-destruction must 30 m or less.

What is the maximum danger area/range that any component or fragment can travel from the point of detonation as a result of detonation due to impact or the self-destruction mechanism? A statement to this effect is required.

Self Destruct Capability

The projectile must provide a reliable self-destruct capability, which eliminates duds on the ground. The % of duds (if any) expected from the self-destruct mechanism must be stated.

Maintainability
The ammunition must be maintenance free for a minimum of 10 years while contained in the specifically designed packaging and stored in temperature conditions ranging between – 10 degrees C and 50 degrees C.
