AAWSAP DIRD: Space Access: Where We’ve Been and Where We Could Go, March 8, 2010 — Department of War Research Paper

Incident Overview

This Defense Intelligence Reference Document was written under the Advanced Aerospace Weapon System Applications Program (AAWSAP), the Defense Intelligence Agency contract run by Bigelow Aerospace Advanced Space Studies, and is dated March 8, 2010. It was declassified and published on September 18, 2026 as part of the sixth tranche of the Department of War’s Presidential Unsealing and Reporting System for UAP Encounters (PURSUE). The released copy carries redactions.

What the government released

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.

Related records

This paper was written under the contract set out in AAWSAP Statement of Objectives and AAWSAP Solicitation and Original Order, which defined what AAWSAP was asked to study. Read those first: they explain why a program framed around foreign aerospace threats commissioned papers on subjects this far from any known aircraft.

The case in this archive

This record is a primary source for the Advanced Aerospace Weapon System Applications Program, written up here at length from the contemporary record. The file and the case history are worth reading against each other: the document is narrower and more cautious than the account that grew up around it, which is usually the point.

Status of the case

A Defense Intelligence Reference Document is a literature review, and the government’s own summary asks that it be read as one: a reference and synthesis product rather than original research, released without any implication that the concepts it discusses have been validated. The paper collects and summarises published work. It does not report an observation, test a device, or offer evidence that anything it describes has been built, by the United States or anyone else. That caveat matters most for the papers on warp drives, wormholes, antigravity and negative energy, which survey theoretical proposals that remain speculative and in several cases depend on physics no experiment has shown to exist. AAWSAP was a Defense Intelligence Agency contract, awarded in 2008 to Bigelow Aerospace Advanced Space Studies in Las Vegas, to anticipate foreign aerospace threats decades ahead, and its 38 reference papers show what the program chose to spend its time on. The All-domain Anomaly Resolution Office has made no finding about this document, and none is implied by its release.
