Lighthouse Keepers React to Attack on Pearl Harbor

Seventy-five years ago today Americans were stunned at the news of the Japanese bombing of Pearl Harbor. Most lighthouse keepers shared the news in their logbooks and noted the immediate effects of this event at their station.

At Makapuu Point Lighthouse, located not far from Honolulu on the island of Oahu, the lighthouse log entry for December 8, 1941, begins “War against Japan was declared by President Roosevelt after Japan attacked without warning Naval & Army bases on Oahu. Watches have been rearranged effective today on a basis of 4 hours on and 8 hours off without liberty. . . .”

On the December 8, 1941, the Keeper at Cape Arago Light Station on the Oregon coast does not note the attack but does report that he “put the radiobeacon out of commission at 2146 and total black [out] at 2300 per orders received.” 
Soon after December 7, 1941, the U.S. Coast Guard would become part of the U.S. Navy. The lighthouse personnel became part of the War effort as the military set up defense and communications at many of the stations. At key stations the number of station personnel would increase substantially to cover additional duties such as beach patrol, plane lookouts, radar, radio communications, etc. Some coastal lighthouses were extinguished or dimmed and many lightships were taken off their stations to avoid sinking by enemy submarines. All coastal keepers were drilled in blackout measures should the need arise.

    1. By WWII, there were other forms of navigation being used besides lighthouses. Radio Navigation, also known as the “flying beam” was an important advancement during this time: Before the war, radio navigation could only provide a course or a bearing to a station. The invention of timekeeping technologies, such as the crystal oscillator, led to a new era of systems that could fix position accurately and were easier to use. Each system of radio navigation uses time in a slightly different way and each requires its own type of navigational charting.
      By World War II, a web of air navigation radio stations and beacons connected by “airways” began to cover the globe. When war broke out, new military equipment revolutionized air navigation. This allowed less experienced users to achieve the same results as highly trained celestial navigators and eventually decreased the need for professional navigators.
