KH-13

From Wikipedia, the free encyclopedia

The KH-13 is a name used by observers of U.S. military space programs to refer to a class of imaging reconnaissance satellite operated by the United States. The KH-13 is the putative successor to the "KH-12" IMINT satellites, the last of which was launched in 1999.

[edit] Interpretations

In 1995, a Los Angeles Times article reported that the 8X program was intended as "a major upgrade to the KH-12". However, the 8X was reported to depart from the KH-12 in that the 8X was speculated to weigh 20 tons. The 8X was reported as fulfilling a detailed wide-field-of-view imaging role. The cost of the program was a subject of disagreement from some within the military at the time.[1] [2]

The KH-11/12/13 series are planned to be replaced by the planned Future Imagery Architecture digital imaging spacecraft. The contract for these planned spacecraft was initially awarded to Boeing in 1999, but in September 2005 the contract was shifted to Lockheed after cost overruns and delays of the delivery date.[3]

[edit] Public observations

Amateur satellite observers have identified several satellites in sun-synchronous orbits which might be new IMINT satellites:

  • USA-144 was launched on 22 May 1999 by a Titan-IV from Vandenberg AFB. NSSDC ID1999-028A. Idenfitied as KH12-4 in NASA's database, it is sometimes identified as part of the Misty program.
  • USA-161 was launched on 5 October 2001 by a Titan-IV from Vandenberg AFB. NSSDC ID 2001-044A
  • USA-182 was launched on 30 April 2005 by a Titan-IVB from Vandenberg AFB. NSSDC ID 2005-16A
  • USA-186 was launched on 19 October 2005 by a Titan-IV from Vandenberg AFB. NSSDC ID 2005-042A [4]
  • USA 193, also known as NRO launch 21 (NROL-21) was launched from Vandenberg Air Force Base[5] on December 14, 2006 by a Delta II-7920 rocket.[6] Less than a month after its launch, it was reported that the U.S. spy satellite, had lost all contact with the ground.[7] On January 29, 2008, an AP story quoted a U.S. Air Force general, who stated that intact pieces of the satellite "might re-enter into the North American area".[8] 2006-057A On February 21, 2008, the United States government destroyed the satellite with a modified SM3 sea-launched missile, due to the possible danger to the public of hydrazine leaking from its fuel tank if it struck a populated area and ruptured upon impact.

[edit] In popular culture

The KH-13 is also the subject of Bruce Sterling's science fiction book The Zenith Angle, released in April 2004. Since the capabilities of the real satellites are not publicly known, it is impossible to compare the abilities of those described in the book to those of the real surveillance satellites.

KH-13 is used as a plot device in The Canadian TV Series ReGenesis in the season 4 episode "The Sounds of Science" Which aired on May 18, 2008
