Spain's C90 anti-tank weapons systems are a group of disposable, shoulder fired grenade launchers built by the Spanish company Instalaza.
All consist of a preloaded launch tube with a pyrotechnic firing mechanism. This means that they do not need batteries or any other type of electrical charging system.
They all have an optical sight with a permanent light source for night operations.
All use a 3.54 inch (90mm) caliber warhead.
Each of the C90 anti-tank grenade launchers can be carried and fired by one man.
The earliest versions of the C90 anti-tank weapons system, the C90-C and the C-90-C AM , were each33.07 inches (840mm) long and weighed 9.26 pounds (4.2 kg)
Since then, this group of weapons has been upgraded to the C90-CR (M3) series. Each of the weapons in the C90-CR (M3) series is 37.01 inches (940mm) long, to accommodate a larger rocket motor.
Variants within the C90-CR (M3) series include:
The C90-CR (M3) - an anti-tank weapon that can pierce 15.75 inches (400mm) of armor at a distance of 328 yards (300m). It uses a HEAT round that is capable of penetrating 1.09 yards (1 meter) of concrete.
The C90-CR-RB (M3) - an anti-tank weapon that can penetrate 18.90 inches (480mm) of armor at a distance of 328 yards (300m). It fires a HEAT round that can penetrate 47.24 inches (1200mm) of concrete.
The C90-CR-AM (M3) -an anti-armor, anti-personnel weapon. It has a weaker armor penetration than the C90-CR and the C90-CR-RB (M3). It can penetrate only 8.66 inches (220mm) of armor at a distance of 200 yards. It is capable of penetrating 2.13 feet (0.65) meters of concrete.
When engaged in its anti-personnel function, the C90-CR-AM fires a dual-purpose HEAT-FRAG charge with a range of 875yards (800m) and a lethal fragmentation radius of 69 feet (21m).
The C90-CR-BK (M3) - an anti-bunker weapon with a tandem (dual) warhead. One charge is designed to pierce through a wall, and then a second charge explodes inside the building. It can penetrate 383 yards (350m) of concrete.
The C90-CR-FIM (M3) - an incendiary weapon that contains red phosphorous
The C90-CR, the C90-CR-RB and the C90-CR-AM each weigh 10.36 pounds (4.7 kg). The C90-CR-BK weighs 11.24 pounds (5.1kg) and the C90-CR-FIM weighs 11.68 pounds (5.3kg).
