The U. S. Navy Mine Defense Laboratory conducted a series of tests on a simulated nuclear submarine running light array at sea under normal nighttime operating conditions. The tests were made to determine the maximum range at which the light array could be recognized. Observers were selected from military personnel who normally stand duty watch as lookouts. Tests indicated that with an atmospheric transmission rate of 70 per nautical mile the maximum range of visibility for the lights in the array was white masthead light, 9.3 miles green starboard sidelight, 2.1 miles and red port sidelight, 2.3 miles.
