As its designation implies, the LRAC 89-F1 fired a rocket of 89mm caliber. Muzzle velocity was rated at 967 feet per second with an effective range within 500 meters and a maximum range out to 2,300 meters. Sighting was accomplished through use of an APX M290 scope and a passive night telescope sight were also available. The base penetration rocket was fin-stabilized (spring-loaded) while in flight and can pierce up to 400mm at a 0-degree angle and up to 110mm at 65-degrees. Broken down, the projectile featured an electric generator at its head followed by the cap and head with the fuse at the midway point. The projectile was then largely made up of the propulsion charge and finally ended with the exhaust nozzle. The launch tube contained the integrated sighting device, trigger mechanism and bipod. The rocket was not made active until the rear tube container was affixed to the launcher. Only then the rocket's propellant was not activated until after the rocket was fired. The rocket was then armed some 32 feet from the launch point.
Design of the base LRAC launcher was essentially a detailed tube. The tube was larger at the rear and tapered off to a consistent forward end. The main control components were held at the center of the tube and included a pistol grip type handle, a retractable forward hand grip and an adjustable ergonomically curved shoulder rest with twin feet (bipod). The sighting system was mounted near the pistol grip unit (or firing generator handle). A carrying handle was set to the right side of the tube body. The rear of the tube was capped by a removable plug and the front by a removable muzzle cover. A back sight notch was mounted atop the business end of the muzzle.
Beyond the base issue rocket, LRAC ammunition included an anti-personnel/anti-vehicle projectile (spraying out up to 1,600 high-speed, molded steel pellets), a pair of smoke projectile (35 second disbursement time in either liquid smoke/phosphorous head forms) and an illumination projectile that burned in air for up to 30 seconds at 300,000 candela power, settling to the ground by a small parachute.
The LRAC 89-F1 in French Army service has since been replaced by the AT4-CS (of Sweden) single-shot and the ERYX portable wire-guided anti-tank weapons. The LRAC does, however, continue service with other militaries around the world, thee being primarily former French colonies residing in Africa.
