 | | While the German firm Heckler & Koch produces a specialised underwater pistol, the P11, no known Western manufacturer produces an underwater rifle of any type.The APS was designed by a team headed by Vladimir Simonov, the nephew of Sergei Simonov, designer of the ubiquitous SKS carbine. |
 | | The APS fires from the open bolt to allow the barrel to fill with water, which is necessary to its reliable operation with the rod-shaped bullets it fires.The range of the APS is dependent on the depth at which it is fired: the deeper, the shorter the effective range. |
 | | The ships on which the two heads of state met were protected by a 16-man team of divers armed with the APS underwater rifle.It is not known how many, if any, APS rifles have been sold on the international arms market to Western users. |
