Philadelphia Experiment -- Master Case File

Philadelphia Experiment -- Master Case File

The Philadelphia Experiment -- also known as Project Rainbow -- is an alleged secret United States Navy experiment purportedly conducted at the Philadelphia Naval Shipyard in Philadelphia, Pennsylvania, on or around October 28, 1943. According to the claims that have circulated since 1955, the destroyer escort USS Eldridge (DE-173) was rendered optically invisible and teleported approximately 215 miles from Philadelphia to the Norfolk Naval Operating Base in Norfolk, Virginia -- before being instantaneously returned to Philadelphia. The alleged experiment is further said to have resulted in catastrophic consequences for the crew: sailors driven insane, others suffering violent burns and mysterious illnesses, and some allegedly found physically fused into the ship's metal hull, still alive.

The story traces entirely to a single original source: Carl M. Allen (alias Carlos Miguel Allende), who began writing letters to astronomer and UFO author Morris K. Jessup in January 1956, claiming to have witnessed the event from the nearby merchant vessel SS Andrew Furuseth. Jessup initially dismissed Allen as a crackpot. The story received an unexpected boost in 1957 when a heavily annotated copy of Jessup's book arrived at the Office of Naval Research (ONR), which had 127 copies privately printed. Jessup died in 1959 under circumstances his associates considered suspicious. The story was further expanded by Charles Berlitz and William L. Moore in their 1979 book The Philadelphia Experiment: Project Invisibility, and later by Al Bielek, who claimed to be an amnesiac survivor of the experiment itself.

The official position of the United States Navy is absolute and documented: no such experiment ever occurred. The USS Eldridge's deck logs, the logs of the SS Andrew Furuseth, and the records of multiple other vessels contradict every element of the claim. The ship was in the Bahamas on October 28, 1943 -- not in Philadelphia. The Andrew Furuseth left Philadelphia on October 25, three days before the alleged experiment. Multiple naval historians, physicists, and investigative journalists have concluded the story is a fabrication, likely originating with Allen's troubled mental state and his peculiar obsession with Einstein's Unified Field Theory.

Nevertheless, the Philadelphia Experiment occupies a central and permanent place in American conspiracy culture. It directly spawned the Montauk Project mythology; it inspired a major 1984 film; it influenced the creation of the Netflix series Stranger Things; and it remains the foundational narrative for an entire genre of classified-military-black-project storytelling that continues to generate books, documentaries, and online discussion.

Primary Reference Data

Field	Detail
Official name	No official name -- the experiment is alleged to have been called "Project Rainbow" by proponents
Alleged date	October 28, 1943 (most common claim); some sources say July 1943 for a preliminary test
Alleged location	Philadelphia Naval Shipyard, Philadelphia, Pennsylvania; Norfolk Naval Operating Base, Virginia (destination)
Ship involved	USS Eldridge (DE-173) -- Cannon-class destroyer escort; commissioned August 27, 1943
Alleged result	Optical invisibility; teleportation 215 miles to Norfolk; crew injuries; sailors fused to hull
Original source	Carl M. Allen (alias Carlos Miguel Allende); letters to Morris K. Jessup beginning January 1956
Alleged witness ship	SS Andrew Furuseth (Liberty ship; Allen claimed to be a deckhand aboard)
Scientific basis claimed	Einstein's Unified Field Theory; electromagnetic fields; Zero Time Reference Generator (Tesla)
Key scientists alleged	Albert Einstein; Nikola Tesla (died January 7, 1943 -- months before alleged experiment); Dr. John von Neumann
US Navy position	Experiment never occurred; Eldridge logs show ship in Bahamas on October 28, 1943; no research into radar or optical invisibility conducted
ONR investigation	Office of Naval Research received annotated copy of Jessup's book in 1957; two officers fascinated; 127 copies of "Varo Edition" printed; official conclusion: no experiment
The Varo Edition	127 privately printed copies of Jessup's "The Case for the UFO" with three-color handwritten annotations allegedly by Allende and others; printed by Varo Manufacturing (a military contractor)
Key books	"The Philadelphia Experiment: Project Invisibility" -- Berlitz and Moore, 1979; "The Case for the UFO" -- Jessup, 1955
Al Bielek	Man who claimed to be an amnesiac survivor; real name Edward Cameron; said he recovered memories after seeing the 1984 film; died October 10, 2011
Film adaptation	"The Philadelphia Experiment" (1984) -- directed by Stewart Raffill; starring Michael Pare; produced by John Carpenter
Montauk connection	The experiment is the claimed origin point for the Montauk Project -- alleged continuation at Camp Hero, Montauk, New York, 1971-1983
Degaussing explanation	Real classified technology at the Philadelphia Navy Yard involved degaussing -- wrapping ships in electromagnetic cables to neutralize magnetic signatures against magnetic mines; this is the most credible "kernel of truth" explanation
Official Navy statement	September 8, 1996: ONR stated "ONR has never conducted investigations on radar invisibility, either in 1943 or at any other time"

Why the Story Refuses to Die

Despite overwhelming evidence that the Philadelphia Experiment never occurred, the story has remained in active circulation for nearly 70 years. Several factors explain its durability:

The Varo Edition: The inexplicable decision by two ONR officers to print 127 copies of an annotated conspiracy book about a supposed Navy experiment, using a military contractor, gave the story a veneer of institutional legitimacy it would never have achieved on its own.

Jessup's death: The 1959 death of Morris K. Jessup -- found in his car with a hose from the exhaust pipe in Matheson Hammock Park, Florida -- was ruled a suicide, but his colleagues found the timing and circumstances suspicious. He had recently told associates he had made a "breakthrough" in his research.

Real classified research: The Navy was conducting genuine classified electromagnetic research in Philadelphia in 1943. Degaussing technology was real, classified, and visually dramatic -- ships wrapped in large cables and charged with high-voltage current. This real secret program provides a credible "kernel of truth" around which the fabricated elements were built.

Einstein's Navy employment: Albert Einstein was genuinely employed by the U.S. Navy as a scientific consultant from 1943. His involvement in electromagnetic research -- separate from the Manhattan Project -- is documented. The claim of his involvement in the Philadelphia Experiment is false, but it is not entirely absurd on its face.

The Montauk amplification: The emergence of the Montauk Project mythology in the early 1990s reframed the Philadelphia Experiment not as a failed one-time experiment but as the beginning of an ongoing decades-long black project program, giving it new significance and a larger narrative universe.
