Here are updated versions of most of the program descriptions, I'll update my homepage once I have RASV and ALSV figured out also. Comments and corrections are welcome.
Advanced Military Space Flight Capability (AMSC)
Initiated by AFSC with one-year study contracts awarded to General Dynamics and Rockwell in 1981. Technology studies of small manned spacecraft based on two generic launch concepts: subsonic air launch and "staged" ground launch. Replaced by the Advanced Military Space Technology (AMST) program with a contract awarded to Boeing in January 1984 to determine key aerodynamic and performance parameters associated with air-launching a so-called AMST/TAV orbiter from a carrier aircraft.
Transatmospheric Vehicle (TAV)
Program begun in mid-1982. Stanley Tremaine coined the term “Transatmospheric Vehicle”, as the craft should be able to operate with equal efficiency both within the atmosphere and in space and be capable of transitioning from space into the atmosphere and back. Phase I of the TAV study began in May 1983 with Battelle Laboratories working with Boeing, General Dynamics, Lockheed, and Rockwell. McDonnell-Douglas submitted its own unsolicited TAV proposal. Phase I ended in December 1983 and resulted in 14 vehicle concepts. Phase II started in August 1984 with a twelve-month contract to Science Applications. In Phase II selected industry concepts were evaluated against alternative solutions such as advanced aircraft and the necessary technologies were further examined with emphasis on determining the military effectiveness of a TAV. The TAV was expected to be the size of a small airliner with a gross liftoff weight of 1 to 1.5 million lbs and using up-rated SSMEs for propulsion in the first generation. A TAV Project office was established in December 1984 under the direction of Lt Col Vince Rausch. By early 1986 the TAV program had been replaced by NASP with the entire TAV staff transferring into the NASP JPO.
Science Dawn
A classified program begun in 1982 to determine the technical feasibility of a military aerospace plane. Requirements were for a sled-launched horizontal-takeoff / horizontal-landing single stage to orbit (SSTO) launch vehicle powered by a modified SSME with a two-position nozzle. Dry mass was to be 100,000-150,000 lb, takeoff mass 1,2-1,5 million lb with a 10,000 lb payload to a polar orbit from Grand Forks AFB. AMSC concepts from Boeing, Lockheed and McDonnell Douglas were hand-picked for further development with Rocketdyne and Air Products as propulsion contractors. The Boeing concept was apparently their RASV vehicle. The McDonnell Douglas proposal, possibly GRM-29A, had a down- pointing SSME in the nose to cater for the runway requirements, whereas Lockheed used a ramped takeoff with two solid boosters. By 1984 it had become clear that horizontal takeoff was inappropriate use of rocket power, and the program was superseded by Science Realm.
Science Realm
The program was initiated in 1984 as a follow-on to Science Dawn. In contrast to Science Dawn, which stressed horizontal takeoff, Science Realm investigated vertical takeoff SSTO designs, capitalizing on the high thrust-to-weight ratio of a rocket engine. During the program structural test articles were designed based on Science Dawn designs. The cost of Science Dawn and Science Realm together was about $20 million.
Have Region
In 1986 Science Realm was followed by the Have Region program, to complement the ongoing air-breathing work in the NASP program. Main goal was to further develop structures and TPS to reduce risk. Under the program three prototype lightweight structures in scales from 40 to 100% were fabricated from exotic metals, primarily titanium and high-temperature superalloys, to evaluate near-term flight readiness. In tests the Boeing concept was validated and the built but untested Lockheed and McDonnell Douglas designs were classified as partial successes. The test articles were within 3% of required SSTO design weights. Regardless in 1988 it was concluded that the materials developed for NASP were more promising. Total cost of Have Region was around $40 million.
Copper Canyon and NASP
In June 1983 DARPA initiated the classified Copper Canyon program to investigate the potential military applications of air-breathing hypersonic and single stage to orbit vehicles and technologies with Vince Rausch as project director. Tony DuPont’s initial design from 1983 originated from a NASA study into engine cycles and was a 50,000 lb “F-15 sized“ aircraft. Funded with $6 million for 1983, with Battelle Laboratories doing the main work and initial contracts for airframe work to Boeing, Lockheed and General Dynamics, and propulsion work to Marquardt and GASL. In mid-1985 the TAV group at the USAF Aeronautical Systems Center became aware of the work being done under Copper Canyon. The TAV studies and contractor designs had concentrated on rocket-based single stage to orbit vehicles rather than the air-breathing vehicles envisioned by Copper Canyon. Soon both groups were discussing a multibillion dollar effort to produce a single stage to orbit aircraft in collaboration with NASA and other DOD agencies to reduce the cost of access to space. In October 1985 the USAF ASC launched the Advanced Aerospace Vehicle (AAV) program to develop advanced hypersonic military aircraft. In December 1985 the National Aerospace Plane (NASP) program was born, a civilian led national effort to develop a single stage to orbit vehicle. NASP JPO was established in January 1986, and president Reagan announced the NASP in his first state of the union address in February 1986. Copper Canyon constituted Phase I of NASP program.
The objective of NASP was to develop two flight vehicles with air breathing propulsion from takeoff to orbit. Rocket engines were to be used for final orbital insertion and orbital maneuvers. Airframe, engine module and test facility RFPs were sent out in November 1985. In April 1986 the first design contracts for the NASP program were awarded. Contractors included Boeing, Lockheed, McDonnell Douglas, General Dynamics and Rockwell, with Pratt & Whitney and General Electric for propulsion research. Rocketdyne later contributed to NASP under its own funding. In October 1987, following Phase 2A evaluation, Lockheed and Boeing were dropped from the NASP program, alongside General Electric.
Throughout the NASP program the Department of Defense had an 80% share of all money spent on the program. In 1989, during his first week of office as the Secretary of Defense, Richard Cheney terminated the DoD NASP effort. A program review by the National Space Council recommended extending Phase 2 to 1993. In 1991, the National Team program approach combined the resources of the five contractors in a joint-venture partnership to develop a single X-30 concept. Upon completion of the Phase 2D technology development portion in 1993, the technological maturity was deemed not to be at the level required to justify a $15 billion investment to develop two X-30 aircraft in Phase 3, and the NASP was finally cancelled in May 1993.
