The Philadelphia Experiment
Legend says the Navy made a warship invisible in 1943 — and some of the crew came back fused into the deck.
The Philadelphia Experiment is a persistent legend claiming the U.S. Navy made the destroyer escort USS Eldridge invisible, or even teleported it, during a 1943 experiment — a story that traces back almost entirely to one man's unverified letters, with no confirmed Navy record of any such test.
⇄disputed
Quick facts
- →The entire legend traces back to letters written by one man, Carl Meredith Allen, in the early 1950s.
- →The Navy's actual deployment record places the Eldridge on ordinary convoy duty during the claimed experiment dates, not in Philadelphia.
- →Claims include the crew going insane or becoming fused into the ship's hull — details with no supporting documentation.
- →The USS Eldridge was later sold to Greece and scrapped in 1999, having never been involved in any documented secret experiment.
