Gun Platform No. 2 - 1945
San Diego Naval Training Center
The three weapons are 3-inch 50 calibre duel purpose guns. Developed in the 1930s, the design was light weight for its time and used until automatic anti-aircraft weapons were perfected. This weapon was favored on smaller ships such as support vessels and anti-submarine escorts. It fired a fixed round which combined the thirteen pound shell and propellant in an attached casing like a bullet. It could fire a shell nearly seven miles at a muzzle velocity of 2,700 feet per second.
