Menon was an anti-submarine mortar used by the Italian Navy during the Cold War.

Introduced in 1956, it was used on the Centauro-class and Bergamini-class frigates and Impetuoso-class destroyers until their retirement in the 1980s.

The Menon system fired a 305-millimeter (12 in) projectile weighing 160 kilograms (350 lb) to a maximum range of 1,500 meters (4,900 ft).

[1] This was replaced by the K 113 weapon with a single 4.6-meter (15 ft 1 in) 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 400 and 900 meters (440 and 980 yd).
