Blackstar is the reported codename of a secret United States orbital spaceplane system. The possible existence of the Blackstar program was reported in March 2006 by Aviation Week & Space Technology (Aviation Week, AWST) magazine; the magazine reported that the program had been underway since at least the early 1990s, and that the impetus for Blackstar was to allow the United States government to retain orbital reconnaissance capabilities jeopardized following the 1986 Challenger disaster. The article also said that the United States Air Force's Space Command was unaware of Blackstar, suggesting it was operated by an intelligence agency such as the National Reconnaissance Office.
Aviation Week speculated that such a spacecraft could also have offensive military capabilities, a concept colloquially known as "The Space Bomber". The magazine also stated that it was likely that Blackstar would be mothballed, although it is unclear whether this is due to cost or failure of the program.
The Blackstar system
Aviation Week describes Blackstar as a two stage to orbit system, comprising a high-speed jet "mothership" aircraft (which Aviation Week referred to as the SR-3). Its description of SR-3 is similar to the North American B-70 Valkyrie Mach 3 strategic bomber, and to patents filed in the 1980s by Boeing. The SR-3 would carry a second, smaller airframe, codenamed the XOV (eXperimental Orbital Vehicle) underneath, between its two laterally separated engine-banks, containing each 2 or 3 engines. This rocket-powered spaceplane, with similarities to the X-20 Dyna-Soar project, would be released by its mothership at an altitude of around 100,000 feet. The XOV would then light its rocket motor (aerospike engines, similar to those used by the Lockheed Martin X-33), and could achieve both suborbital and orbital flight; one source quoted by Aviation Week estimates the XOV could reach an orbit of 300 miles (480 km) above the Earth, depending on payload and mission profile. The XOV would then reenter the atmosphere and glide back to any landing site where it would land horizontally on a conventional runway. This combination of jet-powered mothership and a smaller rocket-powered spaceplane resembles the civilian Tier One spaceplane system as well as NASA's X-15, but capable of much higher velocities and of thus attaining orbit. Readers are cautioned to examine the challenges involved in supersonic separation of vehicles as opposed to the more common subsonic separation of ordnance from aircraft, but this separation from the belly might be easier than from the top, which proved to be problematic on the Lockheed D-21/M-21.
The primary use of a military spaceplane such as Blackstar would be to conduct high-altitude or orbital reconnaissance, allowing surprise overflights of foreign locations with very low risk of the spyplane being successfully engaged by existing air-defense systems. This is similar to the goals of the earlier U-2 and SR-71 Blackbird reconnaissance aircraft; in some circumstances such an overflight yields more information than a pass by a reconnaissance satellite, as the satellite's path is predictable, allowing sensitive material to be hidden.
Military analysts[who?] have suggested that a military spaceplane could also be used to place small satellites in orbit, to retrieve them, to provide a means of launching nuclear weapons from orbit, or to serve as a platform for exotic orbit-to-ground hypervelocity weapons. The small spaceplane described by Aviation Week appears to have only a very modest cargo capacity, limiting its use in such missions.
Aviation Week suggests that the huge costs of the Blackstar program were borne both by the Department of Defense's own black budget and by hiding the costs of Blackstar inside the procurement costs attached to acknowledged military purchases. To assist in this, and to allow politicians to deny the USAF operates such a vehicle, the Blackstar assets may nominally be owned and operated by the civilian defense contractors who built it. The magazine suggests that a consortium of Boeing and Lockheed are responsible for Blackstar.
It is unclear if the Blackstar program became fully operational, although it may have been so since the mid-1990s. Aviation Week's article speculated that the success of Blackstar explains the Government's willingness to cancel the SR-71 Blackbird and Air Force satellite-launch programs.
Discussions of similar aircraft
During the 1970s, when studies were underway which led to the specification of the Space Shuttle, most leading US aerospace contractors explored orbital spaceplane designs, some based on a two-stage design. The most serious of these was the Lockheed HGV under the X-24C program, which was a manned hypersonic vehicle dropped from underwing a B-52, even to the point of rumors that it had actually been flight tested, according to Encyclopedia Astronautica. With the adoption of the Space Shuttle design, these avenues appear to have been abandoned. The use of a spaceplane as part of the launching system to replace the Space Shuttle has been suggested in programs such as VentureStar.
Some of the details of the SR-3 resemble the rumored Brilliant Buzzard or “Mothership” aircraft, but these were supposed to carry their second stage aircraft on top, rather than on the bottom as with the SR-3. This second stage was rumored to be Aurora, (a high-speed, high-altitude delta-winged aircraft), and the lengthening of runways at facilities such as Area 51 (taken by some as evidence of Aurora) could instead be necessary either to support SR-3's takeoff or XOV's landing. Most descriptions of Aurora, however, describe it as a hypersonic plane with exotic engine technology; the SR-3 described by Aviation Magazine is similar to existing rocket-powered aircraft. Pulse Detonation Engine (PDE) technology, visually apparent by donuts-on-a-rope contrail - and audibly by its deep bass pulsing boom noise, has been associated with these programs from eyewitness accounts during the 1990s.
In the late 1960s the North American Aircraft Corporation studied conceptual designs using the B-70 bomber for small space launch of an X-15 type rocket plane. These were abandoned as unpromising.
What is known, and a matter of public record, is that, through the 1980s and 1990s, the USAF did undertake a series of projects to study, research, develop and test demonstrator vehicles capable of SSTO (single-stage-to-orbit) and TSTO (two-stage-to-orbit) missions. These programs were code-named, in order, SCIENCE DAWN, SCIENCE REALM, COPPER CANYON, and COPPER COAST, and involved the development of three different competitive demonstrator vehicles. It was at the conclusion of COPPER CANYON's design phase that President Reagan proposed the X-30 NASP, which is claimed by the Blackstar story to have been used to pay for development of this spaceplane.
According to one declassified RAND Corp. report, two of the three vehicles failed to achieve their full flight envelope (i.e. couldn't make orbit), while the third, an "assisted SSTO", did achieve orbital capability. Furthermore, three code-named programs to design the stealthing of these three vehicles fell under the programs known as HAVE BLINDERS I, HAVE BLINDERS II, and HAVE BLINDERS III. All of these programs can be found in US military budget documents, with associated budget account numbers for years in the 1980s up into the late 1990s in the case of COPPER COAST, though the code name was dropped from the account number in the mid-1990s, even though many millions were budgeted up until recent years.
Whether any of these vehicles were individually code named "BLACKSTAR" is unknown at this time.
Computer-generated concept videos of the tests of this vehicle were made available by NASA / Lockheed Martin in June 2008.
May 2006 UK Defence report on "Black" aircraft sightings
In May 2006, the British Ministry of Defence (MoD) released an extensive report on Unexplained Aerial Phenomena (UAPs) in the UK air defence area . It was written by the Defence Intelligence Staff in 2000 and was originally classified "SECRET UK eyes only". One of the Working Papers is entitled ""BLACK" AND OTHER AIRCRAFT AS UAP EVENTS". It says "it is acknowledged that some UAP sightings can be attributed to covert aircraft programmes". The report lists three "Western" programmes which might result in this – all of which appear to be American. The first – not surprisingly – is the SR-71. Programme 2 and Programme 3 are redacted from the report – even their names are withheld. Two photos are also redacted. This was reported on June 14, 2006 by BBC Newsnight.
