Menon was an anti-submarine mortar used by the Italian Navy during the Cold War. Introduced in 1956, it was used on the {{sclass|Centauro|frigate|0}} and {{sclass|Bergamini|frigate}}s and {{sclass|Impetuoso|destroyer}}s until their retirement in the 1980s.

Description

The Menon system fired a {{convert|305|mm|adj=on|sp=us|0}} projectile weighing {{convert|160|kg|sp=us}} to a maximum range of {{convert|1500|m|sp=us}}. It fired 21 rounds in 70 seconds that covered an area of about {{convert|90|by|180|sqyd}}.Friedman, p. 434

The initial version consisted of a three-barrel mortar in a rotating, enclosed mounting that was usually positioned forward of the superstructure, but aft of the gun mounts.Archer, p. 230 This was replaced by the K 113 weapon with a single {{convert|4.6|m|ftin|adj=on|sp=us}} barrel in the same type of mounting, albeit with a fixed elevation of 45°. By varying the gas vent valves in the three powder chambers, the weapon had a range between {{convert|400|and|900|m|yd|sp=us}}. The K 113 fired a seven-round pattern, loaded automatically from a seven-round cylinder.

Short-barreled models were also used, although details are lacking.
