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.

It is here proposed to give the spacecraft a topologically equivalent shape, using the entire spacecraft for the electrostatic energy storage (see Figure 4 ). There toroidal currents flowing azimuthally around the outer shell of the spacecraft not only magnetically insulate the spacecraft against the surrounding electron cloud but also generate a magnetic mirror field that can reflect the plasma of the exploding fusion bomb. In addition, the expanding bomb plasma can induce large currents, and if these currents are directed to flow through magnetic field coils positioned on the upper side of the spacecraft, electrons from there can be emitted into space surrounding the spacecraft by thermionic emitters placed on the inner side of these coils, inductively charging (Reference 12) the spacecraft for subsequent proton beam ignition pulses. A small high-voltage generator driven by a small onboard fission reactor can make the initial charging, ejecting from the spacecraft negatively charged pellets. With the magnetic insulation criterion E < B ( E,B, in electrostatic units, esu), where Bis the magnetic field surrounding the spacecraft measured in gauss, then for B= 104G, E = 3 x l03 esu = 9 x 105 V/cm, one has E-(1/ 3)B, hence E < B. A spacecraft with the dimension / - 3 x l03 cm can then be charged to a potential El- 3x l09 volts, with the stored electrostatic energy on the order of & - (£ 2/ 8,r) [ 3 • For E = 3 x 103 esu and l = 3 x 103 cm, & is on the order of 1 gigajoule. The discharge time is on the order of r -1/c, where c = 3 x l0'0 cm/s is the velocity of light. In our example, we have r - 10-7 sec. For a proton energy pulse of 1 gigajoule, the beam power is 3 x l016 erg/s = 30 petawatts, large enough to ignite a pure deuterium explosion. Lifting of Large Payloads Into Earth Orbit To lift large payloads into Earth orbit remains the most difficult task. For a launch from the Earth's surface, magnetic insulation inside the Earth's atmosphere fails, and with it the proposed pure deuterium bomb configuration. A different technique is suggested here, one I had first proposed in a classified report dated January 1970 (Reference 9), declassified in July 2007, and thereafter published (Reference 17). A similar idea was proposed in a classified Los Alamos report, dated November 1970 (Reference 18) and declassified in July 1979. In both cases the idea is to use an expendable laser for the ignition of each nuclear explosion, with the laser material thereafter becoming part of the propellant. The Los Alamos scientists had proposed to use an infrared carbon dioxide (CO2) or chemical laser for this purpose, but this idea does not work, because the wavelength is too long and therefore unsuitable for inertial confinement fusion. I had suggested an ultraviolet argon ion laser instead. However, since argon ion lasers driven by an electric discharge have a small efficiency, I had suggested a quite different way of pumping it, illustrated in Figure 5. There the efficiency can be expected to be quite high. It was proposed to use a cylinder of solid argon, surrounding it by a thick cylindrical shell of high explosive. If simultaneously detonated from outside, a convergent cylindrical shockwave is launched into the argon. For the high explosive, one may choose hexogen with a detonation velocity of 8 km/s. In a convergent cylindrical shockwave, the temperature rises as r ·0A , where r is the distance from axis UNCLASSIFIED/fFOR OFFI&I.t.L YSE OHLl/ 16
