Source measurement	—	The SPG-9 Kop'yo ( Russian : СПГ-9 Копьё , transliterated: Stankovyi Protivotankovyi Granatomet "Kop'yo" - Easel Anti-tank Grenade Launcher "Spear") is a tripod-mounted man-portable, 73mm caliber recoilless gun developed by the Soviet Union . It fires fin-stabilized, rocket-assisted high explosive (HE) and high-explosive anti-tank (HEAT) shaped charge projectiles similar to those fired by the 73mm 2A28 Grom low pressure gun of the BMP-1 armored vehicle. It was accepted into service in 1962, replacing the B-10 recoilless rifle .^[source]SPG-9 · Lead; only the objects and conditions stated in this passage The projectile is launched from the gun by a small charge, which gives it an initial velocity of between 250–400 metres per second (820–1,310 ft/s). The launch charge also imparts spin to the projectile by a series of offset holes. Once the projectile has traveled approximately 20 metres (66 ft) from the launcher, a rocket motor in its base ignites. For the PG-9 projectile, this takes it to a velocity of 700 metres per second (2,300 ft/s) before the motor burns out.^[source]SPG-9 · Description; only the objects and conditions stated in this passage The SPG-9 is heavy, ~60 kilograms (130 lb), and normally transported by vehicle, and carried into position by its two person crew. It can be deployed in about a minute. The weapon is in service with a large number of armed forces, and a variety of ammunition is produced; however, they are mostly copies of the original Soviet PG-9 HEAT and OG-9 fragmentation high explosive (Frag-HE) rounds.^[source]SPG-9 · Description; only the objects and conditions stated in this passage
