The SPG-9 Kopye (Spear) is a Russian tripod-mounted man-portable, 73 mm recoilless gun developed by the Soviet Union. It fires fin-stabilised, rocket-assisted HE and HEAT projectiles similar to those fired by the 73 mm 2A28 Grom low pressure gun of the BMP-1 vehicle. It was accepted into service in 1962, replacing the B-10 recoilless rifle.
The projectile is launched from the gun by a small charge, which gives it an initial muzzle velocity of around 250 m/s to 400 m/s. The charge also imparts spin to the projectile by a series of offset holes in the launch charge. Once the projectile has travelled approximately 20 meters from the launcher a rocket motor in the projectile ignites. For the PG-9 projectile, this takes it to a velocity of 700 m/s before the motor burns out.
The weapon is light, and is normally transported by vehicle, and carried into position by its two crew. It can be deployed in around a minute. The weapon is in service with a large number of armed forces, and a variety of ammunition is produced, however mostly they are copies of the original soviet PG-9 HEAT and OG-9 FRAG-HE rounds.
A variant for use with airborne troops including detachable wheels was built as the SPG-9D.
