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.

The term "minisatellite" refers to a spacecraft with a wet mass (including onboard propellant) of 100 kg to 500 kg. Microsatellite or "microsat" is a spacecraft with a wet mass of 10 kg to 100 kg. Nanosatellite or "nanosat" is a spacecraft with a wet mass below 10 kg. Picosatellite or "picosat" is a spacecraft with a wet mass of 0.1 kg to 1.0 kg. Picosats are also called sub-nanosats. The primary reason for miniaturizing satellites is to reduce cost. Heavier satellites require larger launch vehicles of greater cost while smaller, lighter satellites require smaller and cheaper launch vehicles and can sometimes be launched in multiples or "piggyback" using excess capacity on larger launch vehicles. Miniaturized satellites allow for cheaper designs as well as ease of mass production. However, few satellites of any size other than communications constellations, where dozens of satellites are used to cover the globe, have been mass produced in practice. Besides the cost issue, the main rationale for the use of miniaturized satellites is the opportunity to enable missions that a larger satellite cannot accomplish, such as: • Constellations for low data rate communications. • Using formations to gather data from multiple points. • In-orbit inspection of larger satellites. Many of these missions require numerous small spacecraft in a constellation or "swarm." These include orbital communications networks and swarms of small satellites to conduct remote sensing, and to provide unique perspectives on astronomical bodies of interest. For instance, 100 or more nanosats could be deployed from a mother ship to their final destination in space for deployment. Provisions for orbital maneuvers as well as attitude control, multiple sensors, and instruments, and full autonomy will yield a highly capable miniaturized satellite. All onboard electronics will survive a total radiation dose rate of several hundred kilorads over a several year mission lifetime (at least 100 kilorads over two years) . Nanosats developed for in-situ measurements will be spin-stabilized, and carry a complement of particles and fields instruments. Nanosats developed for remote sensing measurements (MASINT) or surveillance and eavesdropping (SIGINT) will be three-axis stabilized, and carry a complement of imaging and radio wave instruments. Autonomy both onboard the nanosats and at the ground stations will minimize the mission operational costs for tracking and managing a constellation. To reduce overall mission cost, advanced technology components and a novel laser propulsion system will be used to make nanosats and their onboard instruments compact, lightweight, low power, low cost, and able to survive their radiation environment over a several year lifetime. Each nanosat will be manufactured and tested for a recurring cost not to exceed $500k. By producing a large quantity of nanosats for a given mission, the per-unit cost will be reduced to a small fraction of UNCLASSIFIED//FOR 061ilCl.li.k W&& 8Ptl'l 1
