| The APS Underwater Assault Rifle is a derivative of the AK47, designed in Russia in the early 1970's and made in Russia for use underwater by frogmen or combat swimmers. Underwater, ordinary-shaped bullets are inaccurate and very short-range. As a result, this rifle fires a steel bolt caliber 5.66mm (especially designed for this rifle and is often mistaken as 5.56mm) and 120 mm (4.75 in) long. Its magazine holds 26 cartridges. The AK-47 (for Avtomat Kalashnikova model 1947 goda, Russian: автомат Калашникова образца 1947 года) is an assault rifle designed in 1947 by Mikhail Kalashnikov, produced by Russian arms manufacturer IZH, and used in many Eastern bloc nations during the Cold War. ...

APS stands for Avtomat Podvodnyy Spetsialnyy = "Special Underwater Automatic rifle".
The APS's barrel is not rifled; the fired projectile is kept in line by hydrodynamic effects. As a result, the APS is somewhat inaccurate when fired out of water. Its range and firing rate decrease with increasing depth, presumably due to increasing backward suction caused by cavitation behind the projectile, and water pressure on the firing mechanism. Rifling is the means by which a firearm gyroscopically stabilizes a projectile. ...
Hydrodynamics is fluid dynamics applied to liquids, such as water, alcohol, oil, and blood. ...
Cavitating propeller model in a water tunnel experiment Cavitation is the phenomenon where small and largely empty cavities are generated in a fluid, which expand to large size and then rapidly collapse, producing a sharp sound. ...
The APS is longer range and has more penetrating power than spearguns. This is useful in such situations as shooting through reinforced drysuits, and protective helmets (whether air-holding or not), and thick tough parts of breathing sets and their harnesses, and plastic casings and transparent covers of some small underwater vehicles. Spearfishing is a form of fishing that has been popular the whole world over for centuries. ...
drysuits are used in a number of sports to provide a barrier between the occupant and cold water. ...

A Diver Propulsion Vehicle or a DPV is an item of diving equipment used by scuba divers to increase their range while underwater where their endurance is restricted due to limited availability of breathing gas and need to avoid decompression sickness. ...
The APS is more powerful than a pistol, but is bulkier and takes longer to aim, particularly swinging its long barrel and big flat magazine sideways through water. The APS has more stopping power against anti-frogman dolphins, but for most underwater fights, Russian commando frogmen prefer the pistol, which is more compact and easier to store away. It is reported that some Russian frogmen prefer to be photographed with the APS, as it looks bigger and more impressive. The achievements of WWII frogmen, and later events, showed the need to guard against attacks by frogmen on important bases and facilities. ...

However, no American version of the APS is known to exist in the real world. Twilight 2000 is a role playing game set in the aftermath of World War III. The premise is that the United States and the Soviet Union have gone to (limited) nuclear war with all its consequences. ...
