NOSS-2 subsatellite


American military naval signals reconnaisance satellite. 6 launches, 1990.06.08 (USA 60) to 1991.11.08 (USA 77).

NOSS-2 detected the location of naval vessels using radio interferometry, and consisted of a main spacecraft and two subsatellites, which kept station several hundred meters apart.

First Launch: 1990.06.08.
Last Launch: 1991.11.08.
Number: 6 .

  • Titan The Titan launch vehicle family was developed by the United States Air Force to meet its medium lift requirements in the 1960's. The designs finally put into production were derived from the Titan II ICBM. Titan outlived the competing NASA Saturn I launch vehicle and the Space Shuttle for military launches. It was finally replaced by the USAF's EELV boosters, the Atlas V and Delta IV. Although conceived as a low-cost, quick-reaction system, Titan was not successful as a commercial launch vehicle. Air Force requirements growth over the years drove its costs up - the Ariane using similar technology provided lower-cost access to space. More...

  • Titan 4 American orbital launch vehicle. Developed to handle military payloads designed for launch on Shuttle from Vandenberg before the USAF pulled out of the Shuttle program after the Challenger disaster. Further stretch of core from Titan 34, 7-segment solid rocket motors (developed for MOL but not used until 25 years later). Enlarged Centaur G used as upper stage (variant of stage designed for Shuttle but prohibited for flight safety reasons after Challenger). Completely revised electronics. All the changes resulted in major increase in cost of launch vehicle and launch operations. More...

Associated Launch Sites
  • Cape Canaveral America's largest launch center, used for all manned launches. Today only six of the 40 launch complexes built here remain in use. Located at or near Cape Canaveral are the Kennedy Space Center on Merritt Island, used by NASA for Saturn V and Space Shuttle launches; Patrick AFB on Cape Canaveral itself, operated the US Department of Defense and handling most other launches; the commercial Spaceport Florida; the air-launched launch vehicle and missile Drop Zone off Mayport, Florida, located at 29.00 N 79.00 W, and an offshore submarine-launched ballistic missile launch area. All of these take advantage of the extensive down-range tracking facilities that once extended from the Cape, through the Caribbean, South Atlantic, and to South Africa and the Indian Ocean. More...
  • Vandenberg Vandenberg Air Force Base is located on the Central Coast of California about 240 km northwest of Los Angeles. It is used for launches of unmanned government and commercial satellites into polar orbit and intercontinental ballistic missile test launches toward the Kwajalein Atoll. More...
  • Vandenberg SLC4E Titan, Atlas launch complex. First designated PALC2-4 and used to launch Atlas Agena D with KH-7 spysats. Rebuilt after MOL cancellation in 1970 to handle Titan 3D with KH-9 and KH-11 spysats. Upgraded in 1989-1990 for Titan 4. More...
  • Cape Canaveral LC41 Titan, Atlas V launch complex. Complexes 40 and 41 were constructed as part of the Integrate-Transfer-Launch (ITL) Titan launch facility at the north end of Cape Canaveral in the early 1960s. Over the next three decades, the complexes supported a wide variety of military space missions involving Titan IIIC, Titan 34D and Titan IV. Complex 41 was deactivated at the end of 1977, then upgraded for the Titan IV program in the 1986-88 period. In October 1999, Complex 41 was demolished with high explosives in order for a new pad for launch of the Atlas 5 rocket to be erected. By then it had been the starting point for 27 Titan flights.
