The RPG-40 was an anti-tank hand grenade developed by the Soviet Union in 1940.[1] A marginally effective design capable of penetrating about 20–25 millimetres (0.79–0.98 in) of steel armour, it was soon replaced by the RPG-43 and later the RPG-6, both used shaped charges to increase penetration.
Despite becoming quickly obsolete, the grenade remained in service post-war as an anti-personnel weapon, and it was also effective against defensive positions such as bunkers or machine gun nests.
Description
[edit]The RPG-40 is a blast anti-tank grenade, with a detonator fitted into a recess in the of the grenade.[4] Its stabilized in flight by a cloth ribbon which unfolds after being thrown.[4][5]
Upon contact, 760 grams (1.68 lb) of explosives contained within it were detonated and produced a blast effect. This enabled about 20–25 mm (0.79–0.98 in) of armour to be penetrated and caused secondary damage, such as spalling, on contact with thicker armour.[1]
Due its heavy weight, the grenade could be only thrown at a very short ranges, around 20–25 metres (22–27 yd) and behind protected positions, due the blast and secondary fragmentation effect.[2] According to Jane's, the grenade have an effective fragmentation radius of 20 m (22 yd).[4]
It was also used against enemy defensive positions such as bunkers, machine gun nests and pillboxes.[6]
History
[edit]The RPG-40 was distributed to Red Army units in 1940, a year before the Great Patriotic War.[6]
It was effective against lightly armoured vehicles such as the Panzer I and Panzer II, but quickly became obsolete once the Germans started deploying heavier and better armoured tanks.[3] The RPG-40 was replaced by the RPG-43 and RPG-6, both designs used a shaped charge warhead to provide better penetration, but it remained in use as an anti-personnel (despite its short range) and anti-bunker weapon.[2]
In the post-war period, surplus grenades were supplied to Warsaw Pact countries. These were used by regular army units as late as 1960,[7] and remained in use with militia units as late as 1987.[4]
During the Vietnam War, the Soviets supplied North Vietnam with RPG-40, RPG-43, and RPG-6 anti-tank grenades.[8]
