The SPP-1 Underwater Pistol was made in the USSR for use underwater by Soviet frogmen as an underwater firearm. It was developed in the late 1960s and accepted for use in 1971. Underwater ordinary-shaped bullets are inaccurate and very short-range. As a result this pistol fires a round-based 4.5 millimetres (0.18 in) caliber steel dart about 115 millimetres (4.5 in) long weighing 12.8 grams (0.45 oz) which has longer range and more penetrating power than speargun spears.
