Defense Intelligence Reference Document Laser Lightcraft Nanosatellites

Defense Intelligence Agency · 77 pages · text from the file's own layer

This Defense Intelligence Reference Document from the Defense Intelligence Agency, dated 1 November 2010, was produced under the Advanced Aerospace Weapon System Applications (AAWSA) Program. It describes nanosatellite technologies and proposes launching nanosats into orbit with laser Lightcraft propulsion. It also covers a weapon mission selection study and multi-megawatt laser options. The author recommends that the Department of Defense and NASA bring Lightcraft R&D back to the United States and restart the X-50LR flight demonstration program.

All of these HEL beam control innovations can be quickly adapted to laser propulsion
applications with little or no additional technical modifications or R&DTE. It is expected
that all of the R&DTE work presently being done by the various DoD directed energy
weapons/HEL programs can be immediately leveraged for laser Lightcraft nano-/pico-
satellite programs should they become established. Primary mirrors with exit apertures
of~ 10 m will be required to launch laser-propelled Lightcraft from ground/sea to LEO
while apertures on aircraft-mounted laser beam control optics will be~ 1.0 m.
