US Naval Base Marianas

On December 10, 1898, Guam was ceded to the United States and the complete island of Guam became a Naval Station.[1][2] Naval Advance Base Saipan was built after the Battle of Saipan ended on July 9, 1944.[3][4] Naval Base Tinian construction started began on August 1, 1944, at the end of the Battle of Tinian.[5] The Marianas Islands Fleet Post Office (FPO) was 3062. Naval Base Tinian had special secret facilities built for the handling of the atomic bombs Little Boy and Fat Man. The bombs were loaded on to the Boeing B-29 Superfortress Enola Gay and Bockscar. The US Naval built bases for troops, ships, submarines, PT boats, seaplanes, supply depots, training camps, fleet recreation facilities, and ship repair depots. To keep supplies following the bases were supplied by the vast II United States Merchant Navy. After the war ended on VJ Day, all but bases were closed, less Guam, which continued at an US Naval Advance Base. [6][7]
