RPG-2

Template:Template other The RPG-2 (Russian: РПГ-2, Ручной противотанковый гранатомёт, Ruchnoy Protivotankovy Granatomyot; English: "hand-held antitank grenade launcher") is a man-portable, shoulder-fired anti-tank weapon that was designed in the Soviet Union. It was the first successful anti-tank weapon of its type, being a successor to the earlier and unsuccessful rocket-propelled grenade RPG-1.

The RPG-2 offered better range and armor penetration, making it useful against late and post-World War II tanks, in contrast to the RPG-1 that had only marginal utility. The basic design and layout was further upgraded to produce the ubiquitous RPG-7.

History

Studying German and US anti-tank rocket designs, in 1944 the Soviets developed the RPG-1 with the goal of combining the best features of the German Panzerfaust single shot recoilless weapon with the US Bazooka rocket launcher. Propelled by a 30 mm cartridge, the high-explosive anti-tank (HEAT) shaped charge round could penetrate about of homogeneous armour.Template:Sfn

Early testing revealed several minor problems, but, by the time these were being solved, 150 mm of penetration was no longer considered effective against modern tanks, even late-war designs like the Panther. The warhead was already straining the abilities of the cartridge and its range was already considered too low.Template:Sfn Modifications to improve this began, but in 1947 the RPG-2 program began as a parallel project. Development of the RPG-2 was carried out by the GSKB-30 design bureau, originally part of the Commissariat for Munitions, but in the post-war period handed to the Ministry of Agriculture to help design farm equipment.Template:Sfn

The main difference in performance between the two were due to size. The RPG-2 used a custom designed cartridge to provide much greater power, and the warhead enlarged to . This improved penetration to , which allowed it to penetrate the frontal armor of all but the very heaviest tanks, and the side and rear armor of any tank. The larger cartridge gave the PG-2 warhead slightly better practical range as well, about against stationary targets.Template:Sfn

The design of the PG-2 differed considerably from that of the PG-1 of the RPG-1. The rear section of the PG-1 consisted of a central tube holding the propelling charge, and a second tube around this carrying the fins. When the round was inserted into the launcher, the second tube was outside the launcher tube, requiring the front of the launcher to be free of any fittings. The PG-2 replaced the fins with small metal leaves attached to the inner tube, and eliminated the outer tube found on the PG-1. This allowed the entire propellant section to be inserted into the launcher, which in turn allowed the sights and trigger assembly to be mounted right at the front of the launcher. This slightly reduced the length compared to the RPG-1, made the entire assembly more robust, and allowed the use of conventional fore-and-aft sights.Template:Sfn

The new design was such an improvement on the earlier design that development of the RPG-1 ended in 1948. The first production versions of the RPG-2 entered service with the Soviet Army's infantry squads in 1954.Template:Sfn Although the RPG-2 could be operated by one man, standard military practice called for a two-man crew: a grenadier carrying a Stechkin APS, the launcher and a purpose-built backpack containing three grenades and an assistant armed with a rifle and carrying another three-grenade backpack. Template:Sfn

In 1957, the launcher was adapted to be able to mount the NSP-2 infrared (IR) night-sight system, which consisted of an IR spotlight and a detector, together weighing (with batteries) . The NSP-2 was usable out to under good conditions. When fitted with the NSP-2, the launcher became known as the RPG-2N.Template:Sfn

Widely distributed to allies of the Soviet Union, it was also produced under license by China, North Vietnam and North Korea. Used against the U.S. military in the Vietnam War, its Vietnamese variants were called the B40 ("Bazooka, 40mm")Template:Sfn and B50, using the Chinese Type 50 HEAT warhead.Template:Sfn

PG-2 high-explosive anti-tank (HEAT) projectile

The RPG-2 anti tank grenade launcher is a simple 40 millimeter steel tube into which the PG-2 grenade is fitted. The tailboom of the grenade inserts into the launcher. The diameter of the PG-2 warhead is 80 mm. The center section of the tube has a thin wooden covering to protect the user from the heat generated by the grenade launch. The wooden covering also makes using the weapon in extreme cold conditions easier.

The total length of the weapon with a grenade fitted is and it weighs . Only a simple iron sight is provided for aiming.

Only one type of grenade, the PG-2 high-explosive anti-tank (HEAT), was used in the RPG-2. The propellant, consisting of granulated powder, is in a rolled cardboard case treated with wax that has to be attached to the grenade before loading. Once attached to the propellant charge, the grenade is inserted into the smooth-bore launcher from the front. A tab on the body of the grenade indexes in a notch cut in the tube so that the primer in the propelling charge aligns with the firing pin and hammer mechanism.

To fire the RPG-2, the grenadier cocks an external hammer with his thumb, aims, and pulls the trigger to fire. Upon launch, six stabilizer fins unfold from the grenade.

The weapon is accurate, depending on the soldier's experience, against stationary targets up to and against moving targets at ranges of less than . It has a muzzle velocity of and can penetrate armor up to thick.
