A French missile launcher with missile jointly developed by Somchem, as a low-weight anti-tank weapon with considerable strike effect.

The extensive use of plastics led to the development of a low-weight anti-tank weapon with considerable strike effect. The LRAC-89 launcher is normally operated by a crew of two, a loader and a gunner. The weapon was designed by Societe Technique de Recherches Industrielles de la Mecanique and manufactured by Nationale d'Armes de Saint-Etienne, France. The weapon consists of the launch tube on which an adjustable shoulder piece fore-grip, electrical firing mechanism and has an APX M 290 passive night telescopic that is graduated between 100 and 1,000 meters are mounted. The 89mm rocket itself was developed jointly by SONCHEM, South Africa, together with France and Germany and was battle tested in Southern Angola during the 1980s. The missile is carried in a sealed container and is loaded by attaching a sealed rocket container to the rear of the launcher thus extending the length of the launcher and ensuring that all of the propellant is burnt before the missile leaves the muzzle. The watertight rear plug of the rocket container is removed just before firing and this action closes the firing circuit and allows the rocket to be fired.

The rocket is propelled by a large number of long sticks of tubular propellant that produce a constant pressure while burning, providing constant acceleration. The rocket engine burns out before the rocket leaves the launcher at a velocity of approximately 300 meters per second. As soon as the rocket leaves the launcher, nine fins fold backwards from the rear. These fins provide stability for the rocket while it is in flight. There are two safeties. The first is a bore-riding pin located mid-body of the projectile that blocks the warhead firing circuit. After the projectile leaves the tube, the bore-riding pin falls out releasing the second safety which prevents detonation until the rocket has traveled at least 10 meters from the launcher. The rocket reaches a range of 330 meters in about 1.25 seconds, and 360 meters in 1.36 seconds. Burnout of the rocket is achieved inside the launcher and does not leave exhaust particles thus eliminating the need for protective clothing. The fin-stabilized rocket has an effective range of between 300 and 500m and is pre-packed in a discardable launch canister that can be fired in all weather conditions. The maximum firing range for this weapon is 2 300m at a 45° angle.

After firing the empty rocket container is removed and a fresh one is reinserted. The launcher has a life of approximately 130 firings, after which the optical sight is removed and the launcher is discarded. The optical sight can then be fitted to a fresh launcher. The rocket has a shaped charge warhead that can penetrate 400 millimeters of armour or one meter of concrete at 0 angle impact of the armour plating and is capable of penetrating NATO single heavy, double medium and double heavy targets while still having enough energy to penetrate multiple 10 millimeter thick steel witness plates.

A number of other rockets were developed for this launcher, including a dual purpose anti-personnel/anti-vehicle rocket whose warhead contains 1,600 steel balls along with a smaller HEAT anti-armour warhead. The steel balls have a lethal radius of approximately 20 meters and the shaped charge is capable of penetrating up to 100 millimeters of steel plating. A smoke round was developed, that produces smoke for approximately 35 seconds; and an illumination round that produces 300,000 candela for 30 seconds. The rate of fire is between 3 and 4 missiles per minute.
