World War II

Part of the Harbor Defense of Long Island Sound.

Originally built as an World War II reinforced concrete coastal gun battery with two 16" MarkII-M1 guns mounted on M4 carriages. This was a single level 16" gun battery with both guns casemated and separated by a central magazine and support facility. Shells were moved from the magazine to the gun loading platform by chain hoists traveling on an overhead track system. Electrical power furnished by an internal power plant and by commercial power. The whole facility was covered with earth except for the gun ports and the battery entrances. Additional foliage and camouflage netting provided further cover.
