These were the AN/M3 and M24 aircraft guns converted for use as small-craft surface weapons. The AN/M3 was a derivative of the Swiss Hispano-Suiza HS404 cannon, which was introduced in the late 1930s. These guns were not widely used on US aircraft until after World War II when the improved AN/M3 version was developed. This version was then used to arm many fighters and bombers during the 1950s. The AN/M3 gun used lubricated, percussion-primed ammunition. The M24 aircraft gun was a further modification that fired electric-primed ammunition, which the Air Force considered to be more reliable than percussion ammunition. All of these guns operated with an open breech and had a gas-assisted, blowback operation, with the recoil motion being used to feed the next round of ammunition.
During the Vietnam War, the Navy acquired a fleet of small craft which were used to patrol the coastal waters and rivers of Vietnam. These boats had a need for larger automatic weapons than the 0.50' (12.7 mm) BMG. By the 1960s, the number of Oerlikons available was limited and spares were becoming difficult to find, so the Navy decided to adapt AN/M3 aircraft guns for shipboard use. These modified guns were then designated as Mark 16. Unlike the Oerlikon, the Mark 16 was belt-fed and fired a larger and more powerful round. There were two principal versions of the Mark 16 in service: Mod 4, which has an electrical trigger mechanism, and the Mod 5, which has a hand-operated stepped mechanical trigger.
Ammunition was linked and fed through a feed chute to the delinking feeder on top of the gun. Lubrication for the ammunition was provided by a pump that put a drop of semi-fluid lubricating oil (LSA) in the chamber each time the gun fired.
About 5,000 Mark 16 guns were delivered during the Vietnam War. In 1982 those guns and mountings still remaining in naval service were described as being unreliable and difficult to maintain and were subsequentially phased out in favor of the 25 mm chain gun. However, many Air Force M24 guns were cannibalized during the 1980s and 1990s to provide spare parts for the US Coast Guard which had continued to use the Mark 16.
Unless otherwise noted, the data that follows is for the Mark 16 Mod 5.

Projectiles for these guns are very similar to those for the Oerlikon 20 mm guns of World War II fame. They differ by having a smaller explosive cavity at the rear of the projectile. This makes for a thicker wall around the base which better resists the crushing action created by the driving band as the projectile travels down the gun barrel.

- The Mark 67 used a single ammunition box containing 385 linked rounds. The Mark 68 had two 200 round boxes, which allowed the gunner to switch between two different kinds of ammunition by switching belts.
- The Mark 68 was considered an interim design until the Mark 67 could enter series production.

The 5'/54 caliber Mark 16 gun (spoken 'five-inch-fifty-four-caliber') was a late World War II–era naval gun mount used by the United States Navy, and later, the Japan Maritime Self-Defense Force. These guns, designed specifically for the Montana-classbattleships, were to be the replacement for the 5'/38 caliber secondary gun batteries then in widespread use with the US Navy. https://jetree928.weebly.com/why-cant-i-open-dmg-files-on-mac.html.
Design[edit]
The 5'/54 cal gun turrets were similar to the 5'/38 caliber gun mounts in that they were equally adept in an anti-aircraft role and for damaging smaller ships, but differed in that they weighed more, fired heavier rounds of ammunition, and resulted in faster crew fatigue than the 5'/38 cal. guns.
The ammunition storage for the 5'/54 cal. gun was 500 rounds per turret, and the guns could fire at targets nearly 26,000 yards (24,000 m) away at a 45° angle. At an 85° angle, the guns could hit an aerial target at over 50,000 feet (15,000 m).
The cancellation of the Montana-class battleships in 1943 pushed back the combat debut of the 5'/54 cal guns to 1945, when they were used aboard the US Navy's Midway-classaircraft carriers. The guns proved adequate for the carrier's air defense, but were gradually phased out of use by the carrier fleet because of their weight (rather than having the carrier defend itself by gunnery the task would be assigned to other surrounding ships within a carrier battle group). These mounts were then installed in the Japanese Akizuki-class and Murasame-class destroyers in 1958–59.[1]
