SS Andrew Furuseth was a Liberty ship built for the United States Maritime Commission during World War II.

[2] The Andrew Furuseth is likely best remembered as the ship that Carl M. Allen/Carlos Miguel Allende was to have been serving on in October 1943 when he claims to have witnessed the teleportation disappearance and reappearance of USS Eldridge as part of the Philadelphia Experiment.

[13][14][15] On 25 October 1943, Andrew Furuseth steamed from Hampton Roads as part of Convoy UGS 22 and arrived at Casablanca on 12 November.

[17] Through the end of 1943, the ship plied the waters of the Mediterranean, calling at Augusta, Oran, Naples, and Bizerte, before returning to Hampton Roads on 17 January 1944.

[25][26] The ship operated locally in the Mediterranean through the end of November, at which time Andrew Furuseth returned once again to Hampton Roads.

[31][32][33][34] With the end of hostilities in Europe, Andrew Furuseth began the task returning troops to the United States.

[35][36][37][38] During the December voyage from Antwerp, a soldier aboard Andrew Furuseth was transferred by motor launch in mid-ocean to U.S. Navy transport USS Lejeune for an emergency appendectomy.

[40][41][42] A reputed crew member of the Andrew Furuseth, known variously as "Carl M. Allen" and "Carlos Miguel Allende", claimed to have witnessed the sudden appearance and disappearance of U.S. Navy destroyer escort USS Eldridge (DE-173) in October 1943.

The story goes that, as part of U.S. Navy experiments into rendering ships invisible, Eldridge vanished from its berth in Philadelphia and was accidentally teleported to Norfolk, Virginia and back again on 28 October 1943.
