==Summary==
The 5"/38 (12.7 cm) caliber gun Mark 12 was a US naval gun. It was unquestionably the finest dual purpose gun of World War II. Originally designed to arm new destroyers being built in the 1930s, the 5"/38 (12.7 cm) wound up being used on nearly every major US warship built between 1934 and 1945 and was still being used on new construction as late as the 1960s.
It was also used on many auxiliaries, merchant vessels and smaller warships as well as on US Coast Guard vessels. This standardization, unique in any navy, greatly helped the logistical supply situation of the Pacific War. United States naval gun terminology indicates the gun fired a projectile 5 inches (127mm) in diameter, and the barrel was 38 calibers long, making the 5"/38 dual purpose midway in barrel length between the 5"/51 surface-to-surface and the 5"/25 anti-aircraft guns. The increased barrel length provided greatly improved performance in both anti-aircraft and anti-surface roles compared to the 5"/25 gun.
