The targeting system is reusable but the firing system/tube is single shot. We are getting 158 targeting systems with 1413 ALCOTAN AT (M2) shots. Once fired, the tube is discarded, it comes factory fitted with the projectile and is not meant to be reloaded.
Instalaza C90 90mm Disposable Anti-Tank Rocket Launcher
Spanish military industry has produced many indigenous solutions to local requirements throughout the decades, proving itself a capable player on the world stage. Instalaza SA, founded during World War 2 in 1943, specializes in the field of infantry-level weaponry and developed the MAT-120 mortar cluster munition system, Alhambra hand grenade, and
the C90 series of anti-tank Rocket-Propelled Grenade (RPG) weapons. The latter is a 90mm caliber, single-shot anti-armor solution that entered service with the Spanish Army, Marines, Air Force and Guardia Civil. It has also found a home in the inventories of Colombia, Ecuador, Estonia, India, Italy (special forces), Indonesia, and Malaysia.
The C90 system includes a collapsible fiberglass/plastic launch tube with integrated optics fit and shoulder strap. Overall weight is 4.8 kilograms and its length reaches 940mm. The projectile is a 90mm munition featuring a tandem High-Explosive (HE) warhead with an effective range out to 300 meters. The 2x optical sight can help the operator engage a moving target in either day or night.
The CR-90 family is similar in most respects to the American M72 LAW, both being fired from the shoulder and disposable after single use.
