The Mark 75 three-inch gun is a capable gun in between the Mark 45 and Mark 38. Range is 10 nautical miles and is rated at 80 rounds per minute. Because of performance, lightweight and low manning requirements, the the lightweight, rapid-fire Mk-75 is suited for installation on small combat vessels.
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. Current usage includes one gun mount each for FFG-7 Perry Class Guided Missile Frigates and some Navy hydrofoils, and for one gun mount each for the larger Coast Guard Hamilton and Famous Class cutters.
