These 6" World War II coastal gun batteries were designed to replace obsolete Endicott Period Batteries. Of the 87 planned only 45 were completed and many of those were not completed until late in the war (1944-1945).
The 6" guns fired a 105 pound armor-piercing projectile with a range of over 15 miles at a rate of up to 5 rounds per minute. The gun crews were protected by a thick shield around the gun. Only six of these guns remain in the world, two at Fort Columbia in Battery 246, two at Fort Pickens in Battery 234, and two at Fort McAndrew in Battery 282 in Argentia, Newfoundland and Labrador, Canada.
