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. First produced in the 1950s, by Mecar in Belgium, it was in front-line use by European armies until replaced by disposable tube-launched anti-tank rockets such as the M72 LAW. Although no longer in production, stocks of the grenade still exist and the Energa grenade remains in service with Third World countries. Denel Munition of South Africa manufactured the R1M1, an improved version of the Energa grenade. The original Energa grenade could penetrate 200 mm (7.8 inches) of armor〔()〕 or 500 mm (19.6 inches) of concrete at an angle of impact of 90 degrees. At an angle of impact of 45 degrees, the figures dropped to 100 mm (3.9 inches) and 250 mm (9.8 inches), respectively. The ''Super Energa'' used a rocket booster to extend the grenade's range to 550 meters.〔JIW, p.429.〕 The Super Energa could penetrate up to 275 mm (10.8 inches) of armor and 600 mm (23.6 inches) of concrete. ==US Service== Early in the Korean War, U.S. forces found their World War II-era anti-tank rifle grenades were ineffective against the frontal armor of T-34 tanks. This led the U.S. to produce their own version of the Energa, the M28 rifle grenade, from 1950 until 1960. Originally the M28 was fired from Mecar's proprietary T119 (M1 Garand) and T120 (M1 Carbine) launchers. The T119 was soon replaced by the improved M7A3 launcher (M1 Garand) from September 1952 onwards. The M29 TP (Training Practice) round remained in service until it was replaced in 1961 by the improved M31 TP. The M28 was eventually replaced in US military service by the M31 HEAT rifle grenade and the M72 LAW rocket. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「ENERGA anti-tank rifle grenade」の詳細全文を読む スポンサード リンク
