NOTES: The Island of O'ahu was ringed by hundreds of mass-produced concrete machine-gun pillboxes in 1942. Many still exist. There were six additional positions for 75mm field gun batteries (eight guns each) on the North Shore in 1941 - 1942. There were numerous AA batteries (3-inch, 20mm, 40mm, 90mm, 120mm) emplaced around the island 1942 - 1945. They are not yet listed on this website. Not all of the 155mm and 240mm batteries had guns emplaced at all times. Many were alternate, or "fall back" pre-built positions. The guns were moved where needed.
