The HK P11 is an underwater pistol from the manufacturer Heckler & Koch , which was developed for special units operating in water .
technology
Little was published about the pistol itself. Under water it has a maximum combat range of 10 to 15 m, which increases to about 30 m above water. The penetration force is sufficient to penetrate the first wall of a breathing air container. It has five barrels measuring 7.62 × 36 mm. It is arrow ammunition, which is referred to in English-language literature as "dart". The barrel set must be sent back to the manufacturer for reloading.
It is true that many modern handguns can also be fired under water without suffering any technical damage themselves. Since water is around 800 times denser than air, the projectile loses all energy at a relatively short distance.
With the HK P11 the projectiles work according to the sabot principle. The arrow projectiles rest in a plastic casing that is caught at the muzzle by a choke hole when fired and seals the barrel while the projectile separates from it and flies on. This means that no gases can escape and a barrel can only be shot once. By using a barrel set, multiple shots can be fired with one weapon.
The P11 was developed in the early 1970s and entered service in 1976.
The trigger creates the contact for the electrical ignition. Two 24-volt batteries serve as the energy source. These are housed watertight in the pistol grip, whereby a hygroscopic material is supposed to absorb condensation.
The weapon is used by the German combat swimmers , the United States Navy SEALs and the British SAS as well as by Israeli, Danish, Dutch and Norwegian special forces.
A comparable weapon is the Soviet SPP-1 .
