Måke Anti-Submarine Mortar

The Måke Anti-Submarine Mortar was designed in the later half of the 1940s to provide an element of stand-off to surface ships when engaging submarines which previously required ships to sail close to directly overhead their targets. The weapon was fired automatically from the sonar range recorder, employed in pairs of triple launchers, the six-round salvos were set to explode 25 feet (10 m) above and below the target, the resulting pressure wave crushing the hull of the submarine.
