Design
RKG stands for ''Ruchnaya Kumulyativnaya Granata'' ("handheld
shaped-charge grenade"). The grenade has an odd strap-like lever (or "spoon") that covers the base of the handle and runs up each side of the handle. When the pin is pulled, the "spoon" falls away, and when the grenade is thrown a spring deploys a four-panelled
drogue parachute
A drogue parachute is a parachute designed for deployment from a rapidly-moving object. It can be used for various purposes, such as to decrease speed, to provide control and stability, or as a pilot parachute to deploy a larger parachute. V ...
. This parachute stabilizes the grenade in flight and ensures that the grenade strikes the target at a 90 degree angle, maximising the effect of the shaped charge. Realistic accurate throw ranges are within . The lethality radius is within due to concussion and fragmentation. The casualty radius is within and the danger space from fragmentation is within meters.
The
fuze in the handle activates the grenade. When the parachute deploys, its ejection throws a weight to the rear of the handle and disables the safety. When it impacts or stops, inertia causes the weight to fly forward and hit the spring-loaded firing pin, which activates the primer detonator in the base. This sets off the booster charge in the base of the shaped charge, detonating and enhancing the main charge. The sensitive fuze guarantees that the grenade will detonate if it impacts any target.
Armour penetration depends on the model. The original RKG-3 used a basic shaped charge with a steel liner and could penetrate against
Rolled Homogeneous Armor (RHA). The RKG-3M used a copper-lined shaped-charge warhead and had a penetration of 165 mm; the RKG-3T had an improved copper liner that had a penetration of 170 mm. The RKG-3EM has a larger warhead and boasts a penetration of .
History
The RKG-3 was adopted into service in 1950. A few years later it was replaced by the improved RKG-3M and enhanced RKG-3T. Thicker top armor caused the Soviets to develop the larger RKG-3EM. In early 1970s the Soviet Army replaced this grenade with the
