"Project Rainbow" is another name for the Philadelphia Experiment, but military records show that the code name "RAINBOW" was used for the war plans in place to defeat the Rome-Berlin-Tokyo Axis as early as 1939. "RAINBOW V", the plan in effect on 7 December 1941 when Japan attacked Pearl Harbor, was the plan the U.S. used to fight the Axis powers.

Some researchers have erroneously concluded that the Philadelphia Experiment has a connection with degaussing. During World War II degausing was classified "secret"; it involved a process in which a system of electrical cables are installed around the circumference of ship's hull, running from bow to stern on both sides; smaller ships, such as ''Eldridge'', were docked at degaussing facilities in which the cables were draped around the hull. A measured electrical current is passed through these cables to cancel out the ship's magnetic field.  The degaussing equipment  installed onboard could be turned on whenever the ship was in waters that might contain magnetic mines, usually shallow waters in combat areas.  Properly done, the ship was made "invisible" to the sensors of magnetic mines and torpedoes, despite remaining visible to radar, listening devices, and the human eye.
