Mark 75 ~ 76mm/62 caliber 3" gun
A lightweight, rapid-fire three-inch gun mounted on small combat vessels.
Because of performance, lightweight and low manning requirements, the MK 75 is suited for
installation on small combat vessels. Current usage includes one gun mount each for some
Navy frigates and hydrofoils, and for one gun mount each for the larger Coast Guard
cutters. The Mark 75 was provisionally approved for service use in September 1975.
The Naval Systems Division (NSD) of FMC Corporation and General Electric Co. (Ordnance
Systems Division) were both licensed by the gun's designer, OTO Melara of La Spezia,
Italy, and competed for the right to manufacture the MK-75 in the United States. In 1975,
FMC/NSD won the competition. Since 1981, however, all MK 75 buys have been competed for by
FMC/NSD and OTO Melara.
The first United States produced gun mount was delivered in August 1978.
