This Defense Intelligence Reference Document is dated 11 March 2010. It was prepared by the Defense Intelligence Agency's Defense Warning Office as part of the Advanced Aerospace Weapon System Applications program. It is a technical paper arguing that spacecraft driven by deuterium thermonuclear reactions could be built with current science and could reach the outer solar system. It covers magnetic insulation, ignition by proton beams, a Super Marx generator and conjectured chemical superexplosives. It does not discuss any UFO sightings.
From the source: Release of 2026-09-18 Incident: 3/11/10, 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 advanced nuclear propulsion for crewed deep-space travel and argues that human missions beyond the Moon would require propulsion systems with both very high thrust and very high specific impulse, which the author contends are difficult to achieve with conventional chemical, nuclear-thermal, and nuclear-electric systems. The report focuses on concepts derived from Project Orion, the discontinued General Atomics nuclear pulse propulsion study sponsored first by ARPA and later by the U.S. Air Force between 1958 and 1965, in which a spacecraft would be driven by repeated nuclear explosions. In this case, the DIRD emphasizes small non-fission-triggered fusion explosions using deuterium, magnetic mirrors, and other unconventional ignition concepts intended to avoid the inefficiencies associated with small fission devices. It presents these ideas as a possible pathway to crewed missions across the solar system, while also linking them to broader visions of long-range human expansion into space. The document is exploratory in character and depends on several unproven ignition methods, enabling technologies, and engineering assumptions. Overall, it is a theoretical examination of fusion-based pulse propulsion concepts rather than as a documentary account of a technology nearing practical realization.

For the DD reaction, the situation is quite different because there the instantaneous burn with deuterium of the T- and He3 - reaction products of deuterium makes possible a detonation wave in dense deuterium. In this detonation wave, only 38 percent of the energy released goes into neutrons, compared with 80 percent for the DT reaction . Deuterium can be extracted from water with relative ease in three steps : • Water is electrolytically split into hydrogen and oxygen. • The hydrogen gas, composed of H2 and HD, is cooled down until it liquefies, whereby the heavier HD is separated by the force of gravity from the lighter H2. • The newly produced HD is heated and passed through a catalyst, spl itting HD into H2 and D2, accord ing to the equation (Reference 7) 2HD---+ H2 + D2. Since the gravitational field on the surface of a comet or small planet, from which the D2 shall be extracted, is small, the apparatus separating the liquid HD from H2 must be set into rap id rotation. The comparatively small amount of energy needed for the separation can ideally be drawn from a ferroelectric capacitor (for example, a barium-titanate capacitor with a dielectric constant c: ::::: 5,000), to be charged up to many kilovolts by a small fraction of the electric energy drawn from the deuterium fusion explosions through a magneto hydrodynamic loop (Reference 2). One can also draw this energy from a small on - board nuclear reactor requiring only a small radiator, slowly charging the capacitor. Alternatively, one may store the needed energy in the magnetic field of a superconductor. For the launching of the spacecraft into Earth orbit, a very different scheme is proposed. It requires special materials that are readily available on Earth but not on extraterrestrial bodies serving as landing points to refuel the spacecraft. There the primary resource is water from which deuterium is obtained. In the Orion bomb propulsion project, a large number of fission bombs, or fission triggered fusion bombs, were proposed to lift the spacecraft into space. Since this would release a large amount of highly radioactive fission products into the atmosphere, it was one of the causes that killed Orion. Even though large payloads can be brought into Earth orbit by chemical rockets, this rema ins very expensive, and an acceptable less expensive nuclear alternative is highly desirable. There appear to be two possibilities: • A laser driven by a high explosive, powerful enough to ignite a DT microexplosion, wh ich in turn can initiate a thermonuclear detonation in deuterium (Reference 8) . • A second, more speculative possibility is the conjectured existence of chemical kiloelectronvolt (keV) superexplosives. These are chem ical compounds formed under high pressure, resulting in keV bridges between inner electron shells and able to UNCLASSIFIED/ /POR. 0PPIE!IAL Y§E &PU.¥ 2
