Battery McCook Original Plan

World War I (1917-1918)

The U.S. entry into World War I resulted in a widespread removal of large caliber coastal defense gun tubes for service in Europe. Many of the gun and mortar tubes removed were sent to arsenals for modification and mounting on mobile carriages, both wheeled and railroad. Most of the removed gun tubes never made it to Europe and were either remounted or remained at the arsenals until needed elsewhere. The guns of Battery McCook (2) were ordered dismounted for use abroad on 24 Aug 1917 but were later ordered retained and remounted. The District Engineer reported that the guns of the battery were remounted in June 1920.

World War II (1941-1945)

Battery McCook was a part of the Harbor Defenses of Boston plan throughout World War II. In 1943 the battery was modified to widen the gun platforms and the 6" guns were swapped out at the same time. The new work was begun on 30 Jun 1943, completed on 26 Aug 1943 and accepted for service on 18 Jan 1944 at a cost of $ 7,182.
