Over a century later, the whereabouts of the collier USS Cyclops remains unknown and might never be known… forever lost at sea.

“Weather Fair, All Well.”

That was the last known message radioed by one of the biggest ships of the US Navy, the USS Cyclops (AC-4), amid the ongoing World War I.

USS Cyclops, the second of the four ships of her class built by William Cramps & Sons of Philadelphia, was launched on May 7, 1910, and was commissioned months later to serve as a coal transport to other active Navy ships in European waters, off the Atlantic seaboard, and in the Caribbean as a unit of the Naval Auxiliary Force. By the time America joined the chaos of WWI, the large steaming vessel was designated to the Naval Overseas Transportation Service to fuel British warships in the South Atlantic, as well as mobilize troops into the front.
