The Philadelphia Experiment From A-Z

In 1943 a Destroyer Escort Is Made Optically Invisible
It Teleports out of Control over 600km in Seconds
Men were Fused to the Decks, Some went Crazy…

This site provides some of the highest quality and quantity of images, articles, Most complete collection of the USS Eldridge’s Logs, and original research done on the Philadelphia Experiment of 1943 that can be found on the Internet. DE173.COM is under development right now, so please check back over time.

This website is based on my never released, book (“The Philadelphia Experiment from A-Z.”) Written to provide a complete overview of all acquired information to date on the Philadelphia Experiment of 1943.

I have spent over 35 years digging through books, making phone calls, meeting and interviewing various people. I have walked the decks of the Eldridge’s Sister Ship to get a real idea of the scale of the experiment. I have held original letters from Carl Allen, and poured over government microfilms all in effort to compile the following information.

My interest in the Philadelphia Experiment goes back to the 1980’s with the release of The Philadelphia Experiment, a science-fiction movie drama based on the legend. Later that same week I was in my local public library, and found “The Philadelphia Experiment: Project Invisibility” in pocket novel form, by Charles Berlitz and William Moore. Knowing that books are often better than the movies, I decided to check the book out. Upon reading the book, it became very evident that the authors did not consider the experiment as a fantasy. I have been interested in the subject of mass displacement, time travel, and other fringe topics for a number of years and so this began my journey into this mysterious legend.

Eldridge DE173, 1944, April 25th

As we fast-forward over 35 years, we find that the legend of the Philadelphia Experiment is far from dead. The slim facts that remain are continually being twisted and augmented; this website has been created to pull the twisted information back into perspective.

At present the legend of The Philadelphia Experiment itself revolves around a small group of people that will not be quoted, much less named. These people claim to have unusual knowledge, or even to have been personally involved in the experiment. When these self-proclaimed witnesses do turn up and are asked any direct question, they usually brush it aside or respond using vague (or “technical sounding” to the layman) terms. In preparing this site, and wading through the recent claims of “inside knowledge” on the PX that some are asserting, I have often found myself lamenting “How about showing us some schematic diagrams!” or, as John Lennon might have said, “Just give me some truth!”


Much of what is out there is pseudo-scientific psycho-spiritual fluff. Nevertheless, even though I feel that the credibility of some of the individuals and events discussed on this website are dubious at best, I have included them so that you can see what the present legend is, and how it continues to be embellished. I think Jessup said it best: “There is so much damned nonsense being put out by silly people that one gets disgusted with a lot of it.”  I wonder if he would be surprised to learn that after more then 60 years, and countless books, nothing has changed.

The Current Legend

The following account, culled from a variety of sources and “self-proclaimed witnesses,” describes an event that may or may not have actually taken place. It is the story – or legend – of what has become popularly known as the “Philadelphia Experiment,” also referred to as Project Rainbow.


Project Rainbow

Project Rainbow was allegedly an experiment conducted upon a small destroyer escort ship during World War II, both in the Philadelphia Naval Yard and at sea; the goal was to make that ship invisible to enemy detection. The accounts vary as to whether the original idea was to achieve invisibility to enemy radar or whether the prize sought after was more profound: optical invisibility. Either way, it is commonly believed that the mechanism involved was the generation of an incredibly intense magnetic field around the ship, which would cause refraction or bending of light or radar waves around the ship, much like a mirage created by heated air over a road on a summer day. The legend goes on to say that the experiment was a complete success… except that the ship actually disappeared physically for a time, and then returned. They wanted to “cloak” the ship from view, but they got de-materialization and teleportation instead..

It has been claimed that the Philadelphia Experiment was partly an investigation into how Albert Einstein’s “Unified Field Theory for Gravitation and Electricity” might be used to advantage in the development of electronic camouflage for ships at sea. Einstein allegedly published his Unified Theory around 1925-27 in German, in a Prussian scientific journal, but it was later withdrawn as incomplete. This research was aimed at using intense electromagnetic fields to mask a ship from incoming projectiles, mainly torpedoes. This was later extended to include a study of creating radar invisibility by a similar field in the air rather than in the water.

The story begins in June of 1943, with the U.S.S. Eldridge, DE (Destroyer Escort) 173, being fitted with tons of experimental electronic equipment. This included, according to one source, two massive generators of 75 KVA each, mounted where the forward gun turret would have been, distributing their power through four magnetic coils mounted on the deck. Three RF transmitters (2 megawatt CW each, mounted on the deck), three thousand ‘6L6’ power amplifier tubes (used to drive the field coils of the two generators), special synchronizing and modulation circuits, and a host of other specialized hardware were employed to generate massive electromagnetic fields which, when properly configured, would be able to bend light and radio waves around the ship, thus making it invisible to enemy observers.

The experiment, said to have taken place at the Philadelphia Naval Yard and also at sea, took place on at least one occasion while in full view of the Merchant Marine ship S.S. Andrew Furuseth, and other observation ships. The Andrew Furuseth becomes significant because one of its crewmen is the source of most of the original material making up the PX legend. Carlos Allende, a.k.a. Carl Allen, wrote a series of strange letters to one Dr. Morris K. Jessup in the 1950’s in which he described what he claims to have witnessed: at least one of the several phases of the Philadelphia Experiment.

At 0900 hours, on July 22nd, 1943, so the story goes, the power to the generators was turned on, and the massive electromagnetic fields started to build up. A greenish fog was seen to slowly envelop the ship, concealing it from view. Then the fog itself is said to have disappeared, taking the Eldridge with it, leaving only undisturbed water where the ship had been anchored only moments before.

The elite officers of the Navy and scientists involved gazed in awe at their greatest achievement: the ship and crew were not only radar invisible but invisible to the eye as well! Everything worked as planned, and about fifteen minutes later they ordered the men to shut down the generators. The greenish fog slowly reappeared, and the Eldridge began to dematerialize as the fog subsided, but it was evident to all that something had gone wrong.

When boarded by personnel from shore, the crew above deck were found to be disoriented and nauseous. The Navy removed the crew, and shortly after obtained another. In the end, the Navy decided that they only wanted radar invisibility, and the equipment was altered.

On the 28th of October in 1943, at 17:15, the final test on the Eldridge was performed. The electromagnetic field generators were turned on again, and the Eldridge became near-invisible; only a faint outline of the hull remained visible in the water. Everything was fine for the first few seconds, and then, in a blinding blue flash, the ship completely vanished. Within seconds it reappeared miles away, in Norfolk, Virginia, and was seen for several minutes. The Eldridge then disappeared from Norfolk as mysteriously as it had arrived, and reappeared back in Philadelphia Naval Yard. This time most of the sailors were violently sick. Some of the crew were simply “missing” never to return. Some went crazy, but, strangest of all, five men were fused to the metal in the ship’s structure.

The men that survived were never the same again. Those that lived were discharged as “mentally unfit” for duty, regardless of their true condition.

So, what had begun as an experiment in electronic camouflage, ended up as an accidental teleportation of an entire ship and crew, to a distant location and back again, all in a matter of minutes!

Although the above may seem fantastic, one must remember, that in the 1940’s the atomic bomb was also being invented.

That is the composite Philadelphia Experiment (PX) legend as it has stood up until very recently, when certain new details were added by a few sources who claim to be “remembering” their own participation in the project after years of brainwashing to remove such memories. We will explore these new claims later on in the book.


After reading the above some basic questions my come to mind such as:

  • Is there any evidence that an experiment of this nature was really performed on the U.S.S. Eldridge (or any other ship) in 1943?
  • Did the Eldridge really “teleport” over 600 km in the blink of an eye? How could such an unusual assertion have been made?
  • If there really was an experiment of this nature, what happened to the men involved, and are any of the witnesses still alive after sixty+ years? Have any of them come forth and told their stories?
  • How could the Navy have kept such a technological breakthrough as implied by the PX covered up for over sixty+ years?
  • What kind of technology could have been implemented to cause the events discussed?
  • Were Einstein’s theories really involved? Was his “Unified Field Theory” ever really “completed?”
  • Is the experiment still continuing behind closed doors today, or is the Technology already in use?

These and many more questions will be explored here on the more then 36 webpages you will find on this site.
