Unidentified Aerial Phenomenon (UAP) have been encountered by the military throughout the last 70 years. Whether these objects are a physical reality is open for debate and electronic documentation of these sightings is difficult to obtain. This paper describes the analysis of an Infrared video taken of a UAP encountered by the U.S. Navy in 2004. A Defense Intelligence Agency released video taken by an F/A-18F jet using an AN/ASQ-228 Advanced Targeting Forward Looking Infrared (ATFLIR) system has been analyzed to determine demonstrated accelerations of the UAP. Calculations based on the ATFLIR video, radar information, and testimony from the pilots, are used to derive the velocity, acceleration and estimated power demonstrated by the UAP maneuvers. Calculated UAP accelerations ranged from 40 g-forces to hundreds of g-forces and estimated power based on a weight of one ton ranged from one to nine gigawatts. Manned aircraft such as the F-22 and F-35 are limited to nine g-force and the F-35 has maintained structural integrity up to 13.5 g-forces. Our results suggest that given the available information the UAP capabilities exhibited do not match any known technology in the public domain.
