TR-3B Black Manta

The TR-3B Black Manta is a speculative, unconfirmed black project aircraft alleged to be operated by the United States military. It is popularized in conspiracy theories and ufology as a stealth reconnaissance platform utilizing advanced propulsion. No official government documentation or physical evidence exists to confirm its development or operational status.

The concept of the TR-3B emerged in the late 20th century, popularized by conspiracy theorists who claimed it was developed under a highly classified 'black budget' program. It is often alleged to have been tested at locations like Area 51 during the 1980s and 1990s. Despite numerous alleged sightings of triangular UFOs, the U.S. government has never acknowledged the existence of the TR-3B, and it remains entirely speculative with no verified service history.
