DARPA initiated a Small Standard Launch Vehicle (SSLV) program that led to the Taurus, a launch vehicle designed to supply the Department of Defense with quick-response, low-cost launch of tactical satellites from ground facilities. The initial DARPA model was first test-launched in 1989 and first used operationally in 1994. The prime contractor subsequently offered the vehicle in four versions.

Through its Airborne Launch Assist Space Access (ALASA) program, DARPA has been developing new concepts and architectures to get small satellites into orbit more economically on short notice. Bradford Tousley, director of DARPA’s Tactical Technology Office, provided an update on ALASA today at the 18th Annual Federal Aviation Administration (FAA)’s Commercial Space Transportation Conference in Washington, D.C. Tousley discussed several key accomplishments of the program to date, including successful completion of Phase 1 design, selection of the Boeing Company as prime contractor for Phase 2 of the program, which includes conducting 12 orbital test launches of an integrated prototype system.
Satellites today are launched via booster rocket from a limited number of ground facilities, which can involve a month or longer of preparation for a small payload and significant cost for each mission. Launch costs are driven in part today by fixed site infrastructure, integration, checkout and flight rules. Fixed launch sites can be rendered idle by something as innocuous as rain, and they also limit the direction and timing of orbits satellites can achieve.
DARPA’s Experimental Spaceplane program (formerly known as XS-1) aims to build and fly the first of an entirely new class of hypersonic aircraft that would bolster national security by providing short-notice, low-cost access to space. The program aims to achieve a capability well out of reach today—launches to low Earth orbit in days, as compared to the months or years of preparation currently needed to get a single satellite on orbit. Success will depend upon significant advances in both technical capabilities and ground operations, but would revolutionize the Nation’s ability to recover from a catastrophic loss of military or commercial satellites, upon which the United States today is critically dependent.
