Battery 247 History
Part of the Harbor Defense of the Columbia. One of three like batteries that provided a "triangle of fire" protection for the mouth of the Columbia River. Battery 245 at Fort Stevens, Battery 246 at Fort Columbia and Battery 247 at Fort Canby made up the three points of the triangle.
Armament consisted of two rapid fire 6", Model T2, 309.9" long rifled guns each mounted in a separate shielded M4 Barbette carriage. Between the two guns was a reinforced concrete bunker housing the ammunition and control mechanisms.

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. |
