Project Rainbow (Invisibility Research)

Overview
The name “Project Rainbow” carries a peculiar dual existence in military history. In the real world, it refers to mundane but important wartime technology — specifically, the Navy’s degaussing program that used electromagnetic coils to protect ships from magnetic mines. In the parallel universe of conspiracy theory, it refers to something considerably more dramatic: a classified US Navy program that allegedly used unified field theory physics to render warships invisible to radar and to the naked eye, accidentally teleporting the USS Eldridge from Philadelphia to Norfolk and fusing crew members into the ship’s bulkheads.
The alleged program occupies a foundational position in conspiracy mythology. It is the origin story for the Philadelphia Experiment, which is in turn the origin story for the Montauk Project, which feeds into broader theories about dimensional portals and government time travel. Pull on the thread of Project Rainbow and you unravel an entire tapestry of interconnected conspiracy narratives spanning six decades.
The challenge with Project Rainbow is that it exists in the gray area between real programs and fictional ones. There really were Navy programs involving electromagnetic technology and ships during World War II. The Navy really did have classified research projects. Albert Einstein really did consult for the military. These genuine historical facts have been woven together with pure fiction to create a narrative that borrows enough from reality to seem plausible but that collapses under scrutiny.
Origins & History
The Real Navy Electromagnetic Programs
During World War II, magnetic mines were a serious naval threat. Germany deployed magnetic mines that detonated when they detected the magnetic field of a steel-hulled ship passing overhead. The countermeasure was degaussing — wrapping cables around a ship’s hull and passing electrical current through them to neutralize the vessel’s magnetic signature. The technology was critical, it was classified, and it involved large electromagnetic equipment installed on warships.
The Navy also conducted research into radar camouflage — methods of reducing a ship’s radar cross-section. This involved both physical design features and electronic countermeasures. While not “invisibility,” these programs were classified and dealt with making ships harder to detect.
These real programs provided the raw material from which the Project Rainbow mythology was constructed.
Carlos Allende’s Letters
The conspiracy narrative originates with Carl Allen (who used the pseudonym Carlos Allende), a merchant mariner who in 1955 and 1956 wrote a series of letters to Morris K. Jessup, an astronomer and UFO researcher who had published The Case for the UFO in 1955.
In his letters, Allen claimed to have witnessed a Navy experiment in the Philadelphia Naval Shipyard in October 1943 in which the destroyer escort USS Eldridge was rendered invisible using powerful electromagnetic generators. Allen described the ship being enveloped in a greenish fog, becoming transparent, and then vanishing entirely — only to materialize briefly at the Norfolk Naval Shipyard in Virginia, over 200 miles away, before returning to Philadelphia.
Allen further claimed that the experiment had devastating effects on the crew. Some sailors were allegedly fused into the ship’s structure — their bodies merged with the steel of the bulkheads and decks. Others were said to have become invisible themselves, flickering in and out of visibility for days or weeks afterward. Some went insane.
Allen attributed the experiment to a “Project Rainbow” and claimed it was based on Albert Einstein’s unified field theory — an attempt to unify electromagnetic and gravitational forces that Einstein had been working on (and never completed) throughout the latter part of his career.
The Jessup Connection
Morris Jessup took Allen’s letters seriously enough to correspond with him but did not initially publicize them. However, in 1957, the Office of Naval Research (ONR) received a copy of Jessup’s book The Case for the UFO that had been extensively annotated by what appeared to be three individuals using different colors of ink. The annotations discussed anti-gravity technology, force fields, and various UFO-related topics, and appeared to come from individuals with knowledge of advanced physics.
The annotated book was traced back to Allen, who apparently sent it to ONR. Two naval officers, fascinated by the annotations, arranged for a limited print run of the annotated text, known as the “Varo edition” (printed by the Varo Manufacturing Company). The ONR’s interest in the annotated book — which was unofficial and driven by personal curiosity rather than institutional policy — was later cited as evidence that the Navy was covering up Project Rainbow.
Jessup died in 1959, apparently by suicide. Conspiracy theorists have questioned the circumstances of his death, suggesting he was silenced because he was getting too close to the truth about Project Rainbow.
The Berlitz-Moore Book
The Project Rainbow/Philadelphia Experiment story reached its widest audience through Charles Berlitz and William Moore’s 1979 book The Philadelphia Experiment: Project Invisibility. Berlitz, already famous for The Bermuda Triangle, and Moore, a UFO researcher, presented Allen’s claims along with additional research and interviews. The book became a bestseller and established the Philadelphia Experiment as one of the canonical conspiracy theories of the 20th century.
Berlitz and Moore added details that Allen had not mentioned, including claims about Einstein’s specific involvement, the role of Nikola Tesla (who allegedly designed the original equipment before dying in January 1943), and John von Neumann (who allegedly took over after Tesla’s death). These claims were presented without documentary evidence and appear to have been constructed to make the story more compelling by associating it with famous scientists.
The Montauk Extension
In the 1990s, Preston Nichols and Peter Moon published The Montauk Project: Experiments in Time, which claimed that Project Rainbow continued after World War II and was relocated to Montauk Air Force Station on Long Island. According to this narrative, the program evolved from electromagnetic invisibility into time travel and dimensional portal research, with Al Bielek (who claimed to be a survivor of the original Philadelphia Experiment, having “age-regressed” and been given a new identity) as a key participant.
The Montauk books added layers of narrative — psychic chairs, underground bases, extraterrestrial contacts, and time-traveling children — that moved the Project Rainbow story firmly from the plausible-but-unlikely into the fantastical.
Key Claims
-
Project Rainbow was a classified Navy program: The US Navy conducted a top-secret research program during WWII aimed at achieving electromagnetic invisibility for warships, using Einstein’s unified field theory as its theoretical foundation.
-
Einstein, Tesla, and von Neumann were involved: The program was designed by Nikola Tesla (who withdrew before the experiment), continued by John von Neumann, and based on physics provided by Albert Einstein.
-
The USS Eldridge was rendered invisible: In October 1943, the program’s technology was tested on the destroyer escort USS Eldridge at the Philadelphia Naval Shipyard, successfully making the ship invisible.
-
Teleportation occurred: The Eldridge was accidentally teleported from Philadelphia to Norfolk, Virginia, and back — a side effect of the electromagnetic fields used.
-
Crew members suffered horrific effects: Sailors were fused into the ship’s structure, became invisible, went insane, or were displaced in time.
-
The program continued as the Montauk Project: After World War II, the research continued in secret, eventually achieving controlled time travel and dimensional portal technology.
Evidence
What Proponents Cite
Einstein’s real Navy work: Einstein did consult for the US Navy Bureau of Ordnance during WWII, mainly on conventional weapons-related physics. His consulting role is documented, though its content was classified.
Real degaussing programs: The Navy did install large electromagnetic equipment on warships during WWII as part of the degaussing program. The equipment was classified.
The USS Eldridge existed: The ship was a real Cannon-class destroyer escort, commissioned in 1943. Its existence is documented.
The ONR’s interest in the annotated book: Naval officers did arrange for a limited printing of the annotated Jessup book, which proponents argue indicates inside knowledge of the experiment.
Unified field theory: Einstein really did work on a unified field theory, attempting to unite electromagnetic and gravitational forces. Proponents argue the theory’s equations could theoretically enable electromagnetic cloaking.
Why the Evidence Fails
The Eldridge’s log contradicts the story: The USS Eldridge’s deck logs, now publicly available, show the ship was not in Philadelphia in October 1943. It was on its maiden voyage to Bermuda and back, operating with a convoy escort in the Atlantic. The logs are consistent with normal naval operations and inconsistent with Allen’s claims.
Crew members deny it: Former crew members of the USS Eldridge have been located and interviewed. None reported any unusual experiments. They described normal wartime service.
Einstein’s unified field theory was incomplete: Einstein never completed a unified field theory. The work he did produce was purely theoretical and had nothing to do with electromagnetic cloaking. No physicist has ever proposed a mechanism by which electromagnetic fields could render a macroscopic object invisible or teleport it.
Tesla died before the alleged experiment: Tesla died on January 7, 1943. If the experiment occurred in October 1943, Tesla could not have designed the equipment in the timeframe described (and no evidence places Tesla in any Navy research program).
Allen was unreliable: Carl Allen’s background included periods of apparent mental instability. He admitted in 1980 to making up the annotations in the Jessup book, then retracted his admission. His letters to Jessup contain internal inconsistencies and historical errors.
The ONR printing was unofficial: The Varo edition was arranged by two individuals acting out of personal interest, not as an institutional project. ONR has officially denied any connection to the Philadelphia Experiment.
Debunking / Verification
Project Rainbow as described in the conspiracy narrative is not supported by evidence. The USS Eldridge’s logs, crew testimony, Einstein’s actual research, and the absence of any supporting documentation or physical evidence all argue against the story.
The “unresolved” classification reflects the fact that the term “Project Rainbow” may have been used for real, classified Navy programs — specifically degaussing and radar countermeasures — about which complete information may not be publicly available. The conspiracy narrative appears to have taken the existence of these real programs and attached an entirely fictional narrative to them.
The theory is best understood as a modern legend that evolved over decades, with each retelling adding new details and new famous names. Allen provided the seed. Jessup’s death added mystery. Berlitz and Moore added Einstein, Tesla, and von Neumann. Nichols and Moon added time travel and aliens. By the time the full narrative existed, it bore no resemblance to any documented event.
Cultural Impact
Project Rainbow has had an enduring influence on conspiracy culture as a foundational narrative. It established the template for “secret government physics experiment gone wrong” stories that have been replicated in dozens of conspiracy theories and fictional works.
The narrative’s most lasting contribution may be the idea that the government possesses advanced physics capabilities — invisibility, teleportation, time travel — that it keeps secret from the public. This concept has become a standard element of conspiracy worldviews and has influenced how the public interprets genuinely classified programs.
Within the conspiracy community, Project Rainbow serves as the origin point for an entire mythology. The chain from Rainbow to Philadelphia Experiment to Montauk to dimensional portals represents one of the longest continuous conspiracy narratives in American culture, spanning over 60 years of development.
