| | World War II American Air and Nautical Almanacs |
 | | US Naval Observatory for the duration of World War II to serve as Head Astronomer and Director of the USNO's Nautical Almanac Office, which produced the almanacs used for air and sea navigation. |
 | | When Eckert arrived and war was looming, there was a pressing need for rapid production of accurate and readable air almanacs for use by American flying forces; prior to this, only a couple air almanacs had been produced, and those by old-fashioned, slow, and error-prone manual methods. |
 | | The other major allies, Britain and the USSR, it seems, produced their own air and sea almanacs, rather than sharing, despite the hardships (Britain was bombed by Germany from 1940, and the USSR was invaded in 1941). |
