Documents / Official release
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.

Figure 15. Air-to-Space Concept: Appropriate rotation and translation of a high-energy laser
beam, emanating from a moving aircraft, guides and propels a Lightcraft toward a nearly
head-on collision with an incoming ballistic missile; intermittently, the laser illuminates the
target for guidance updates and for terminal semi-active seeker homing and end-game
maneuvering C26l.
ASSUMED LASER AND LIGHTCRAFT LIMITATIONS
Beamed power levels achievable with envisioned high-energy laser technology are
assumed to be no more than about 10 MW for ground/sea-based lasers, and no more
than about 2.0 MW for the much lighter and smaller airborne lasers installable on
Boeing 74 7, B- 1 Lancer, or C- 130 subsonic aircraft. Lightcraft takeoff masses no more
than about 20 kg can be accelerated to orbital velocities by maximum ground/sea
based laser power levels, and Lightcraft takeoff masses no more than about 4 kg to 8
kg, depending on the magnitude of velocity and acceleration needed, can be
accelerated to very high velocities by the lower allowable masses and power levels of
airborne lasers.
LIGHTCRAFT TRAJECTORY AND MISSION LIMITATIONS
Identified trajectory and mission limitations l261 are:
• Small allowable angle between centerlines of the laser beam and Lightcraft
vehicle axes before significant thrust reduction occurs.
• Small allowable angles-of-attack (angle between Lightcraft centerline and velocity
vector) before significant thrust reduction occurs.
• Limited capability for engaging multiple missile or aircraft threats in allowable
time interval because of relatively long laser beam-riding time against each
threat.
Additional Lightcraft hardware needed for some tactical missions (261 include:
