The first domestic frag grenade was used in the Russo-Japanese war near Mukden. This grenade was invented in 1904 by Captain Nikolai Stepanovich Lishin. Since then, the story of the “explosive fruit” …
The grenade had a long wooden handle, filled with explosive. In the service of the war cap, it was worn on the Lishin’s grenade. There is a wrinkle on the body. The structure of the air flow at the meeting with the obstacle. It was desirable that the grenade fell strictly on the cap, because there was no side impact mechanism. The Lishin grenade system was unsafe. This was a random response. The radius of destruction of the grenade was 9 meters. As a result, the pomegranate did not receive much distribution in the army.
The RG-14 grenade, has become a safer. The RG-14 grenade, compared with the Lishin grenade, was safer for the fighter. Ammonal, TNT, Melinite and Favier composition were used as a pomegranate explosive. The burning time of the retarder was 4 seconds.
After the grenades, it was the most common defensive grenades. The frenzy of the grenade was reckoned. In 1928 it was adopted by the Red Army. Later, the grenade was once again refined for 3.2-4 seconds. Depending on the modification, is 600-750 grams. The damage radius is up to 200 meters.
On the basis of the RG-14, Mikhail Grigorievich Dyakonov in 1933, an RGD-33 grenade was developed. The grenade weighed 495 grams. It is a necessity to make a statement. The ringoon jumps away from the platoon and the pricked up primer cap. Grenade RGD-33 was actively used in World War II, having a good anti-tank weapon.
The RG-41 grenade developed in 1941 by the designer Belyakov was much easier to manufacture. Used a grenade, in contrast to the RGD-33, only TNT, and the detonator with a delay of 3.2-3.8 seconds.
It is a RG-42 grenade. In the case of the body of the grenade. The damage radius is 25-30 meters.
For a more effective, special high-explosive grenades were created in the USSR. One of the first such grenades was the RPG-40, which pierced armor up to 40 mm thick. It was mainly used to destroy the enemy’s shelters.
Later, an RPG-43 grenade was developed on the basis of the RPG-40. She had a significantly lower weight and greater armor penetration. With the explosion of a grenade, a cumulative jet was formed, at a speed of about 12,000–15,000 m / s. The diameter of the 95 mm of armor can be reached at 100,000 kgf / cm. The weight of a grenade is 1.2 kg.
However, the RPG-43 grenade had many shortcomings in terms of safety of use. They were eliminated in the finalized RPG-6 grenade. There was a shock on the waterhead and there was no contact between the warhead and the target. A grenade could pierce armor up to 100mm. The RPG-6 grenade was developed in 1943 and was actively used as a self-propelled gun with 80-100 mm and more. After the war, the Warsaw Pact countries are also armed themselves with RPG-6 grenades. It was not until 1950 that the grenade remained in service.
To replace the RPG-6 in 1950, a manual cumulative grenade GSC-3. Like the RPG-6, the grenade was percussion, but it pierced armor as thick as 150 mm. A cone-shaped tail of the grenade appeared, which was stabilized in flight. Armwork 170–200 mm thick.
To replace the RG-42 in 1954, the RGD-5 grenade was developed. Unlike its predecessors, the grenade had a round body. Trotyl is used as the main explosive. The range of the splinters is 30 meters. The ground for the RG-42 and F-1 grenades. RGD-5 is still in service with the Russian army. In Poland, a copy of the RGD-5 is produced.
RGN and RGO
RGO and RGN grenades also have a round body shape. In grenades, a new fuse UDZS is used where it meets the surface. 184.108.40.206 seconds after a shot. Self-liquidation of a grenade occurs in 3.2-4.2 seconds. The radius reaches 100 meters, the RGN is only 35 meters.
As a means of masking in the 1970s, an RDG-2 smoke grenade was developed. It’s possible to make it out of it. The RDG-2 can be used for different colors.
Especially for grenade launchers, a muzzle-loading grenade VOG-25 was developed. The shot is made according to the “Bezgilzovoy” scheme, the body of the grenade body. This is a grenade launcher to increase the design of the grenade launcher. The grenade is 3–4 times higher than that of the western counterparts.
