PHILADELPHIA, PA
— What began as an experiment in magnetic warfare defense during World War II has grown into one of America’s most infamous military conspiracy theories. The 1943 USS Eldridge experiment, often referred to as the “Philadelphia Experiment,” has long fascinated — and baffled — generations of skeptics and history buffs alike.
The story claims that the USS Eldridge vanished from the Philadelphia Naval Shipyard and reappeared moments later in Norfolk, Virginia. But did a Navy test really lead to teleportation? Or was it a misunderstood attempt at magnetic camouflage?
The Real Goal: Shielding Ships from Magnetic Mines
In 1943, the U.S. Navy was working against deadly threats in the Atlantic — particularly
German magnetic mines
that detonated based on a ship’s magnetic field. To counter this, naval engineers used a process called
degaussing
, which involved running electrical currents through coils wrapped around a ship’s hull to neutralize its magnetic signature.
This wasn’t science fiction. It was smart, real-world physics that helped Allied ships evade underwater bombs. Degaussing effectively made ships invisible — but only to
magnetic sensors
, not the naked eye.
What Actually Happened to the USS Eldridge?
According to official ship logs, the USS Eldridge was never even in Philadelphia when the supposed “teleportation” took place on
October 28, 1943
. Records show the ship was conducting a training cruise in the Bahamas at the time.
Naval documents preserved on microfilm detail the Eldridge’s movements throughout the war, offering a clear paper trail that contradicts the fantastical version of events.
What Witnesses Reported: Glowing Lights and Confusion
Stories of a strange
green-blue glow
surrounding the ship surfaced over the years — fueling tales of invisibility and teleportation. However, this visual phenomenon aligns with something sailors have observed for centuries:
St. Elmo’s Fire
— a real weather effect caused by electrical storms and strong atmospheric charges.
This eerie glow likely added to the mystique but didn’t prove anything paranormal.
How Norfolk Got Pulled Into the Tale
One of the wildest claims was that the Eldridge teleported to
Norfolk, Virginia
, and back. But what many forget is that Philadelphia and Norfolk are connected by inland canals — and during WWII, ships routinely used these routes for two-day transfers.
The confusion over normal military movements — compounded by wartime secrecy — likely helped the myth spread.
The Darker Tales: Crew Trauma and “Fused Bodies”
Perhaps the most disturbing part of the legend involves sailors allegedly being
fused into the ship’s metal
— alive. Others claimed men went insane. But none of these accounts hold up.
There are
no Navy medical records
documenting any such injuries or psychological breakdowns. In fact, crew members later expressed frustration at being tied to the conspiracy, saying they experienced nothing out of the ordinary.
Meet the Man Who Sparked the Legend
The tale began circulating publicly in the 1950s, thanks to a man named
Carl Allen
, aka
Carlos Miguel Allende
, who sent handwritten letters to UFO author
Morris K. Jessup
. Allen claimed to have watched the experiment from a nearby merchant ship, the
SS Andrew Furuseth
.
However, military records place the
Furuseth
nowhere near Philadelphia at the time. Its captain,
Lt. William Dodge
, also denied seeing anything unusual. The story changed every time Allen told it — weakening its credibility.
Was Einstein Involved?
The myth even drags
Albert Einstein
into the mystery. Some versions claim he developed the technology based on his unfinished
unified field theory
. While Einstein did consult for the Navy during the war, he worked on
explosives
, not electromagnetic fields or invisibility.
No official record connects Einstein to the Eldridge or any invisibility research.
What the Navy Actually Says
The U.S. Navy has
denied the Philadelphia Experiment
numerous times. The
Office of Naval Research
, which didn’t even exist until
1946
, has publicly stated it never explored invisibility technology in 1943.
Naval historians have found
no archival evidence
suggesting the military even attempted human invisibility or teleportation experiments.
A Real Destination for Military History Fans
While the USS Eldridge story lives on in pop culture, real military history can be experienced at the
Pritzker Military Museum & Library
, now located in
Somers, Wisconsin
. It houses over 120,000 artifacts, from photos to political cartoons, including exhibitions like
“Drawn to Combat: Bill Mauldin & The Art of War.”
The museum, formerly based in Chicago, is now open
Monday, Wednesday, and Friday
, and offers visitors a deeply researched look at American military operations — minus the conspiracies.
