This Defense Intelligence Reference Document, dated 8 March 2010, was prepared by the Defense Intelligence Agency's Defense Warning Office under the Advanced Aerospace Weapon System Applications Program. It is one of a series of advanced technology reports. It surveys the history of space access concepts, covering hypersonic gliders, air-breathing and rocket propulsion, materials, launch options and operating costs. The report argues that reliable, schedulable access to low Earth orbit is mainly a hardware and organizational problem rather than a technology problem.
From the source:Release of 2026-09-18 Incident: 3/8/10, 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 is a historical and conceptual survey of space access systems, contending that the main barrier to routine access to space is a failure to build durable, reliable, operational hardware and the supporting infrastructure needed for regular service to and from low Earth orbit. The report reviews earlier launch and aerospace concepts, especially reusable and aircraft-like approaches, and suggests that U.S. space access development became too strongly centered on expendable rockets derived from ballistic missiles rather than bespoke systems designed for repeated space access and payload delivery. Its central claim is that meaningful future progress will depend on creating a purpose-built space transportation infrastructure, including frequent round-trip capability and orbital support networks, rather than continuing to rely on one-off launch vehicles. Overall, the document presents a forceful case for infrastructure-first space development, though its characterization of past technological choices is more assertive than a fully neutral account of past U.S. space programming.
UNCLASSIFIED/ /FOA OFFI&iIAk Ulilii ONkY The Qu Tube In the 1990s, a colleague, Ying-Ming Lee, who then worked at MSE in Butte, Montana, showed the author a copper tube about a foot long that was a heat pipe from his colleague in Taiwan. If the tip was put into a cup of hot water, the other end almost instantly was too hot to hold. If it was quickly put into a glass of cold water, that t ip just as quickly became ice cold. As documented in the excerpted page below from the University of Alabama, Huntsville, Annual Report, the apparent conductivity is greater than copper and could not be melted, as the thermal energy would be removed so fast that a significant temperature rise could not be attained. This could have significant industrial application for the United States. The late Clark Hawk had obtained a 10- foot-long Qu tube and tested it in his laboratory. The results were published in the University of Alabama, Huntsville, Annual Report. However, as Clark Hawk discovered, the Chinese team associated with Professor Qu in mainland China was not about to let this discovery into American hands. Plus his team was composed of a number of young, ambitious technocrats who thought they knew how to make their fortune. So both Ying-Ming's and Clark's attempts to advance beyond a demonstration tube ended in frustration . Any attempt to open the tube results in failure, as whatever is in the tube reacts into an inert powder. The author has two smaller tubes in his possession. With applications including hypersonic vehicles, nuclear power plants, and electronic cooling, these devices would lead to an economic breakthrough in practical therma l control.
