This Defense Intelligence Reference Document (DIA-08-1011-001), dated 1 November 2010, was prepared by the Defense Intelligence Agency's Defense Warning Office under the Advanced Aerospace Weapon System Applications program. It covers nanosatellite technologies, laser Lightcraft propulsion, a weapon mission selection study and a multi-megawatt laser study. The author recommends that the Department of Defense, working with NASA, bring laser Lightcraft propulsion research back to the United States and restart the Air Force X-50LR test flight program.
From the source:Release of 2026-09-18 Incident: 11/1/10, Las Vegas, Nevada. Released with redactions. This document is a Defense Intelligence Reference Document (DIRD), a technical reference format used by the Defense Intelligence Agency (DIA) to capture baseline knowledge on a specific topic for later analytic use. DIRDs are best understood as reference and synthesis products rather than as original research. It is one of 38 DIRDs produced under the Advanced Aerospace Weapon System Applications Program (AAWSAP) between 2009 and 2011. Because AAWSAP’s scope permitted a broad range of supporting topics, not every DIRD in the series directly concerns aerospace systems or future threat assessment. The following summary reflects the DIRD’s scope and framing at the time of writing and should not be read as implying current validation of the concepts discussed. This DIRD examines laser-propelled “Lightcraft” as a possible low-cost method to launch very small satellites into low Earth orbit by using a remote high-energy laser to supply most of the propulsion energy rather than relying entirely on onboard energy sources. The report combines a survey of nanosatellite trends with a review of “Lightcraft” propulsion concepts, vehicle design, beam-control requirements, and mission studies, and argues that the most promising application is the launch of nano- or pico-satellites, especially Earth- and space-observing payloads of a few kilograms or less. It presents the concept as potentially much cheaper than conventional multistage rockets for very small payloads, while also noting significant practical constraints including strict beam-riding geometry, atmospheric losses, demanding pointing and adaptive-optics requirements, and heavy dependence on large ground-, sea-, or air-based laser infrastructure. Overall, the document presents laser “Lightcraft” as a technically plausible launch concept whose attractiveness depends on whether the supporting laser and beam-control system can be made reliable and economical at operational scale.

Pico or Nano Satellites UNCLASSIFIED//1'81\ 81'1'1CHtt USE ONLf Chapter 3: Laser Lightcraft Weapon Mission Selection Study The objective of the Froning and Davis [26] study was to examine crucial future Air Force launch vehicle missions and select at least one that might be performed very cost-effectively by Lightcraft vehicles powered by beamed electromagnetic energy from airborne or ground/sea-based lasers. It entai led identification and analysis of promising launch vehicle missions for laser-propelled Lightcraft, and assessments of the identified and analyzed missions by experts in the mission areas. See Figure 14 and Figure 15 for Lightcraft missions that have been identified and explored. It was concluded that the most promising Air Force mission for a laser-propel led Lightcraft is the placement of Earth and space observing nanosats of up to 3 kg mass into LEO. Such a laser-propelled Lightcraft would also serve as a "Lightsat," because it would use the Lightcraft's laser propulsion optics as a telescope for observing military targets on Earth and in space. Additional estimated mass for performing the Lightsat function is no more than about 1 kg, if the Lightcraft forebody structure panels can be unfurled in orbit and used as solar power collectors. Such a Lightcraft system appears capable of reaching LEO at 1/Sth to 1/10th the cost required for placing a similar Lightsat system into LEO using multistage chemical rocket systems.
