The Secret Military TR3B Spacecraft

The TR-3B is a subject deeply embedded in conspiracy theories and UFO lore, often speculated to be a secretive military aircraft with extraordinary capabilities. Described as a triangular craft with three lights at each corner, it’s commonly referred to as a “black triangle.” Equipped with advanced propulsion technology, including an “anti-gravity” drive, the TR-3B is said to use highly pressured mercury accelerated by nuclear energy to generate a plasma field for anti-gravity effects.

Many believe it to be part of covert U.S. military projects, possibly involving reverse-engineered alien technology. However, the evidence for its existence is largely anecdotal, based on numerous UFO sightings of triangular shapes around the world. There’s also mention of a patent for a similar triangular spacecraft, though it was abandoned and filed by an individual, not the military. The discourse around the TR-3B on platforms like X shows a split between those who believe it’s a real, secretive aircraft and skeptics who view sightings as misidentified conventional aircraft or phenomena, or even extraterrestrial in origin. The blend of secrecy, advanced technology, and UFO fascination makes the TR-3B a compelling yet elusive topic where separating myth from reality remains difficult.
