U.S. Department of War · 2010-03-11 · 37 pages · text from the file's own layer

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.

As noted earlier, in comets there is a large amount of deuterium readily ava ilable for
mining. And we know comets also conta in nitrogen and carbon . From th is knowledge
we can assume that very likely other light elements, such as boron, exist in relatively
high concentrations in comets.
Although the waste heat radiator remains a problem, it favors large explosions, because
most of the waste heat accompan ies the propellant into space. Droplet radiators, with
the droplets slowly evaporating, are unlikely to work . Placing the neutron-absorbing
radiators near the shock absorber, permitting them to get red-hot, and thermally
insulating the rest of the spacecraft from the radiators may solve the problem .
Delivery of a Gev Proton Beam Onto the Deuterium Fusion
Explosive
The spacecraft is inductively charged
against an electron cloud surrounding the
craft, and, with a magnetic field on the
order of 104 G, easily reached by
superconducting currents flowing in an
azimutha l direction around the craft, is
magnetically insulated against the
electron cloud up to GeV potentials. The
spacecraft and its surrounding electron
cloud form a virtual diode with a GeV
potential difference. To generate a proton
beam, it is proposed to attach a miniature
hydrogen-filled rocket chamber R to the
deuterium bomb target at the position
where the proton beam hits the fusion
explosive (see Figure 2) . A pulsed laser
beam from the spacecraft is shot into the
rocket chamber, vaporizin g the hydrogen,
which is emitted through the Laval nozzle
as a supersonic plasma jet. If the nozzle
is directed toward the spacecraft, a
conducting bridge is established, rich in
protons between the spacecraft and the
fusion explosive. Protons in th is bridge
are then accelerated to GeV energies,
hitting the deuterium explosive. Because
of the spacecraft's large dimensions, the
jet does not have to be aimed at the
spacecraft very accurately.
