The underwater sub-machine gun is
designed for the arming of combat frogmen
and underwater means for their movement.
The high penetrating power of 5.66-mm
MPS sub-machine gun cartridges
achieved at the expense of an original design of the
bullet and selection of optimal ballistic approach.
At greatest possible ranges of fire under water, the
sub-machine gun provides destruction of a target clothed in a diving suit
with a porolon (flexible polyurethane foam) padding and protected with
organic glass of 5 mm thickness.
The sub-machine gun provides aimed fire with a folded or
extended stock from all positions of the frogman. Also, it may
successfully be applied for the self-defence on overland.
The underwater sub-machine gun provides a single-shot and
automatic fire, has no analogs as to the range of effective fire,
operating characteristics and safety of fire under water and in air.
