Defense Intelligence Reference Document Positron Aerospace Propulsion

Defense Intelligence Agency · 35 pages · text from the file's own layer

This unclassified Defense Intelligence Reference Document from the Defense Intelligence Agency is dated 2 March 2010. It was produced in FY 2009 under the Advanced Aerospace Weapon System Applications (AAWSA) Program. The report reviews work on using positrons as aerospace fuel. It covers air-breathing turbojet and ramjet engines, unmanned aircraft, missiles, single-stage reusable vehicles, positron rockets and a crewed Mars mission, along with how positrons could be produced and stored. It concludes that a first positron-powered flight around the globe could be possible within 10 years.

The GLOW of the positron SSRV is 43 percent less than that of the chemical SSRV
owing to reduced propellant mass. The PTRE will dramatically increase the affordability
of space transportation by increasing the useful payload.
