Program 922 American military anti-satellite system. Study 1968. Program 922 was a non-nuclear sub-orbital ASAT in development in the late 1960's. |
SPIKE American military anti-satellite system. Study 1975. Project SPIKE was a 1970's suborbital conventional warhead ASAT air-launched from an F-106 interceptor. Considerable work was done from the early 1970s under the Missile and Space Defense Program. |
Conventional ASAT American military anti-satellite system. Study 1978. In May 1978, the US Joint Chiefs of Staff issued a priority list of potential Soviet target satellites for the MHV hit-to-kill ASAT then under development. |
USB Russian military anti-satellite system. Study 1978. As platforms for operational versions of space-borne weapons NPO Energia designed a Universal Service Block, based on the DOS-7K space station, in the late 1970's/early 1980's. |
Terra-3 Russian military anti-satellite system. Study 1984. OKB Vympel was the systems integrator for ground-based laser systems. |
RP Russian military anti-satellite system. Study 1985. For interception of enemy ICBM's during boost phase NPO Energia developed a space based rocket interceptor (RP) similar to American 'Brilliant Pebble' systems. |
Polyus Russian military anti-satellite system. The Polyus military test bed was put together on a crash basis as an answer to America's Star Wars program. Missile defence technology satellite, Russia. Launched 1987. |
Zenith Star American military anti-satellite system. Study 1987. In 1987, the Zenith Star prototype space combat satellite prototype, using the Alpha laser, was announced by President Bush. The launch vehicle would be the Barbarian. |
KE ASAT American military anti-satellite system. Study 1989. In 1989 the US Army began a demonstration/validation program to develop a direct ascent kinetic energy ASAT for US forces. |
Gun-Launched ASAT American military anti-satellite system. Study 1990. One of the applications of the superguns Gerald Bull was designing for Iraq would have been firing of an anti-satellite shell that would have blinded Western spy satellites with a sticky material. |
IS-MU Russian military anti-satellite system. Reportedly deployed in 1990. Improved modernized ASAT/ABM. Reportedly deployed in 1980's without flight test, replacing IS-A. Accepted into military service in 1991. ASAT satellite built by TsNII Kometa, USSR. |
Star Lite American military anti-satellite system. Study 1991. In 1991 the Star Lite space laser experiment was made public. Star Lite would weigh half that of the previously planned Zenith Star with a launch mass of 16. |
Spektr - Original Russian military anti-satellite system. Study 1989. Chelomei designed a spacecraft bus for space based weapons based on his TKS space tug. This was an alternate / competitive design to the NPO Energia USB. |
HERTF American military anti-satellite system. Study 1995. |
Space Laser Demo American military anti-satellite system. Study 1996. By 1996 the Star Lite space laser was replaced by the more refined and slightly heavier SLD (Space Laser Demo), weighing 17.4 metric tons). Two versions of the 20 meter long spacecraft were envisioned. |
Space Based Laser American military anti-satellite system. Study 1996. The Operational SBLOV (Space Based Laser Orbital Vehicle) was the final space based chemical laser system envisioned at the end of the SDI / Star Wars program. |
Mitex American military anti-satellite system. 3 launched, 2006.06.21 (USA 187) to (USA 189). Technology satellite built by Orbital Sciences Corp. (OSC) for DARPA, USA. Launched 2006. Used the Aquila-Bus bus. |
Chinese ASAT Chinese military anti-satellite system. Study 2007. On 11 January 2007 a Chinese homing vehicle launched by a ballistic missile from Xichang intercepted and destroyed a Chinese FY-1C satellite at 850 km altitude. |
