It is said that the Rainbow Project is a mysterious experiment carried out by the US Navy on a small destroyer in World War II. It was carried out at the Naval Shipyard in Philadelphia and at sea. The purpose is to make the warship invisible and undetectable by the enemy. As for whether the original idea is to prevent the enemy from detecting the existence of warships on the radar, or to achieve the higher goal of making the enemy turn a blind eye, people's opinions are inconsistent. In any case, the principle of the experiment is to create an incredibly strong magnetic field around the warship, which will refract and bend light or radar radio waves, which is similar to the fog formed by the heated air on the road in summer. The effect is very similar. The plan is said to have been a complete success, except that the warship that was the subject of the experiment also physically "disappeared" for a while and then reappeared. The original intention of the experiment was to hide the ship from sight, but as a result, both the disappearance of the material form and the phenomenon of long-distance transportation appeared. All of this casts a mysterious veil on this plan.
Project Rainbow is said to be part of a research program that applies Einstein's "unified field theory of gravity and current" to electronic camouflage for ships at sea. Einstein is said to have published the unified field theory in a Prussian scientific journal in German between 1925 and 1927, but later retracted it because the theory was incomplete. The original purpose of the research program was to allow underwater ships to use strong electromagnetic fields to interfere and avoid enemy torpedoes. Later, it was extended to generate a similar strong magnetic field in the surrounding air so that enemy radars could not detect their presence.
The story begins in June 1943, and its protagonist is the USS Eldridge, a US Navy escort destroyer numbered DE-173. It has tons of electronic experimental equipment installed on it. Among them, two large magnetic field generators with a power of 75 kilowatts each are installed in the position of the front turret, and the magnetic force they generate is distributed through four sets of huge coils installed on the deck. In addition, there are three radio frequency transmitters (each 2 MW constant-amplitude wave radar), three thousand 6L6 type power amplifier tubes (used to drive the field coils of the two magnetic generators), special synchronization and Modulation circuits, as well as a large number of specially made electronic equipment. Combined, these devices, when properly controlled and tuned, can bend light and radio waves around the ship's hull, making it invisible to enemies.
The specific experiments are said to have been carried out at the Navy Yard in Philadelphia and at sea respectively, leaving people with various legends and speculations.
The next part of the story is the central event. At 9:00 am on July 22, 1943, at the Navy Yard in Philadelphia, the power to the magnetic generator was switched on, and a strong magnetic field began to form around the ship's hull. A green fog slowly enveloped the Eldridge, obscuring it from view. After a while, the fog dissipated and the Eldridge disappeared.
Navy officials and scientists watching from the shore watched with wide-eyed awe at this most remarkable achievement: The Eldridge's hull and crew were not only no longer visible on radar, but even near They can't be seen with the naked eye! Everything happened as expected and far exceeded expectations! About fifteen minutes later, the magnetic field generator was turned off, the green fog reappeared, and the Eldridge reappeared at the same spot where it had disappeared as the fog cleared. However, everyone noticed that something was wrong.
When the personnel on the shore boarded the destroyer, they found that the crew could not tell the direction and felt sick. The U.S. Navy replaced all crew members on the ship and soon replaced them with a new batch of crew members. Later, the Navy determined that the purpose of their experiment was to make the presence of warships invisible to radar, and changed the experimental equipment accordingly.
At 17:15 pm on October 28, 1943, the last experiment on the "Eldridge" began. After the electromagnetic field generator was turned on again, the "Eldridge" became almost invisible: only the outline of the hull could be faintly seen on the water. Everything seemed normal for the first few seconds, but then a blinding blue light flashed and the warship completely disappeared from the water. Even more incredible, within seconds, it turned up in Norfolk, Virginia, a few miles away, and stayed there for a few minutes. The Eldridge then mysteriously disappeared from Norfolk, just as it had mysteriously appeared, and returned to its experimental base at the Philadelphia Shipyard. The scene on the ship after the experiment was even more shocking. Most of the crew felt severe nausea. Some crew members disappeared and never came back. Some crew members went crazy, and the most bizarre thing was that there were five crew members The body and the steel structure of the hull are actually fused together!
The surviving crew members after the experiment became completely different, they could not recall what happened, and regardless of their actual physical condition, they were later judged to be "mentally unfit for service", As a result, they were forced to leave the army, but in the decades that followed, terrifying experiments haunted them like a nightmare, lingering. The U.S. Navy then closed the news, and all records of the experiment were classified as top-secret documents.
An experiment of electronic camouflage led to such incredible and strange things as the long-distance movement of the entire warship and the entire crew, and everything happened in just a few minutes. All these events that allegedly took place in the 1940s seem like a bit of a fantasy to today's people. However, in the era of the birth of the atomic bomb, such a thing was indeed not impossible. Whether it's a visual error or a magnetic shield, it's up to scientists to study.
Recently, the legend of the Rainbow Project has once again become a topic of discussion. Some people who experienced the Philadelphia experiment first-hand claim that after years of brainwashing, they "remembered" what happened that year and added fresh content to this plausible legend. However, what really happened that year is still a mystery to be solved for most people.
