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.

Design[edit]
Mark 2:2-5 New International Version (NIV). 2 They gathered in such large numbers that there was no room left, not even outside the door, and he preached the word to them. 3 Some men came, bringing to him a paralyzed man, carried by four of them. 4 Since they could not get him to Jesus because of the crowd, they made an opening in the roof above Jesus by digging through it. Why would ARRI mark their cameras with a 2.35 ground glass with 2.39 as the scope projection ratio? Is it just a way to 'frame safer'? Also, Aaton has 2.35 and 2.39 available as ground glass markings for the new penelope, as 2.39 is the correct projection ratio, what sense would it make to get a 2.35 ground glass?
- Directed by Christopher McQuarrie. With Tom Cruise, Rebecca Ferguson, Jeremy Renner, Simon Pegg. Ethan and his team take on their most impossible mission yet when they have to eradicate an international rogue organization as highly skilled as they are and committed to destroying the IMF.
- The Mark 39 nuclear bomb and W39 nuclear warhead were versions of an American thermonuclear weapon, which were in service from 1957 to 1966. The Mark 39 design was a thermonuclear bomb (see Teller-Ulam design) and had a yield of 3.8 megatons. The design is an improved Mark 15 nuclear bomb design (the TX-15-X3 design and Mark 39 Mod 0 were the.
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]
