The Los Angeles Air Raid on February 24/25, 1942 opened an extraordinary chapter in the history and evolution of the United States Navy. In response to the incident, policy decisions were made to initiate a covert research program to investigate the feasibility of exotic propulsion technologies such as antigravity, and how to respond to evidence of extraterrestrial visitors. In addition, Navy operatives were embedded in Nazi occupied Europe to learn about the Germans’ advanced technology programs and assistance they were receiving from non-terrestrial sources. The debriefing of the operatives took place at Naval Air Station, San Diego, and were led by Rear Admiral Rico Botta who instructed a “Disseminator of Naval Research and Information,” William Tompkins, to take confidential briefing packets to select think tanks, corporations and university departments. From 1951-1963, Tompkins worked with the Douglas Aircraft Company to design kilometer long spacecraft for a secret U.S. Navy Space Fleet with the covert assistance of alleged extraterrestrial visitors described as “Nordics”. Extensive documents will be presented to substantiate Tompkins claims of the existence of a covert Navy space program in a secret alliance with the Nordics.
