The Energa anti-tank rifle grenade is a rifle-launched anti-tank grenade that is propelled by a ballistite-filled blank cartridge. The name Energa comes from the firm in Liechtenstein that designed it, the Anstalt für die ENtwicklung von ERfindungen und Gewerblichen Anwendungen, based in Vaduz. The Super Energa used a rocket booster to extend the grenade's range to 550 meters. The Super Energa could penetrate up to 275 mm (10.8 inches) of armor and 600 mm (23.6 inches) of concrete.
