Based on its experiences with the launching of short-range theater missiles by [[Iraq]] during the 1991 Persian [[Gulf War]], the [[United States Department of Defense|U.S. Department of Defense]] (DODDoD) concluded that expanded theater missile warning capabilities were needed, and it began planning for an improved infrared satellite sensor capability that would support both long-range strategic and short-range theater ballistic missile warning and defense operations. In 1994, DODDoD studied consolidating various infrared space requirements, such as for ballistic missile warning and defense, technical intelligence, and battlespace characterization, and it selected SBIRS to replace and enhance the capabilities provided by the [[Defense Support Program]] (DSP).

The original contract consisted of 2 SBIRS HEO satellite sensors and 2-3 SBIRS GEO sensors (and satellites) with an option to buy a total of 5 GEOs. A complement of satellites in [[low earthEarth orbit]] (LEO) was planned as part of the program (SBIRS -Low), but this has been moved into the [[Space Tracking and Surveillance System|STSS]] (STSS) program.

'''SBIRS High''' (also now simply referred to as "SBIRS") is to consist of four dedicated satellites operating in geosynchronous earthEarth orbit, and sensors on two host satellites operating in a highly elliptical orbit. SBIRS High will replace the [[Defense Support Program]] (DSP) satellites and is intended primarily to provide enhanced strategic and theater ballistic missile warning capabilities. [[USA-230|SBIRS High GEO 1]] was launched on May 7, May 2011.<ref>{{cite news|url=https://www.reuters.com/article/2011/05/07/us-usa-military-satellite-idUSTRE7462AW20110507|title=Rocket blasts off with missile-warning satellite | work=Reuters | date=7 May 2011}}</ref> Two SBIRS sensors hosted on two classified satellites in highly elliptical orbit have already been launched,<ref>{{cite web |url=http://www.lockheedmartin.com/news/press_releases/2009/0602ss-sbirs.html|title=U.S. Air Force Awards Lockheed Martin US$1.5-Billion Contract For SBIRS Follow-On Spacecraft|deadurlurl-status=yesdead|archiveurlarchive-url=https://web.archive.org/web/20090605074247/http://www.lockheedmartin.com/news/press_releases/2009/0602ss-sbirs.html|archivedatearchive-date=2009-06-05|df=}}</ref> probably as part of the [[List of NRO satellites|NROL-22]] (USA 184) and [[List of NRO satellites|NROL-28]] (USA 200) launches in 2006 and 2008.<ref>{{cite web|url=http://www.satobs.org/seesat/Sep-2005/0336.html|title=Molczan in Satobs message 30 September 2005}}</ref><ref>{{cite web|url=http://www.satobs.org/seesat/Feb-2008/0515.html|title=Molczan in Satobs message 24 February 2008}}</ref> USA 184 and USA 200 are believed by analysts to be [[Signals intelligence|ELINT]] satellites in the family of [[Jumpseat (satellite)|JUMPSEAT]] and [[Trumpet (satellite)|TRUMPET]]; TRUMPET has been reported to have carried an infrared sensor called [[HERITAGE]].

The prime contractor for SBIRS is [[Lockheed Martin]], with [[Northrop Grumman]] as the major subcontractor. [[Lockheed Martin]] also provides the satellite for SBIRS GEO. The system's expected deployment was delayed from December 2009 to 2011 because of problems with Lockheed's workmanship on system components, including unresolved software malfunctions and several broken solder joints in a subcontract procured [[gyroscope]] assembly on the first spacecraft being built.<ref>{{cite news |last=Capaccio, |first=Tony, "|title=Delivery Delayed For Lockheed Martin's Early Warning Satellite", [[|website=Bloomberg.com]], Sep |date=30, September 2009.}}</ref>

It was feared that a further launch postponement into late 2011 would lead to conflict with the planned launches of [[NASA]]'s [[Juno (spacecraft)|Juno]] spacecraft and [[Mars Science Laboratory]], which willwould all use the same launch facility.<ref>Thompson, Loren B.

The SBIRS Low contract is now managed by the [[Missile Defense Agency]] (MDA) and has been subsequently renamed to the [[Space Tracking and Surveillance System]] (STSS).

The '''SBIRS Low''' program was originally expected to consist of about 24 satellites in low earthEarth orbit. The primary purpose of SBIRS Low was the tracking of ballistic missiles; andwith discriminatingdiscrimination between the warheads and other objects, such as decoys, that separate from the missile bodies throughout the middle portion of their flights. The system was to have two major sensors, coordinated by an on-board computer:

*a scanning infrared sensor, designed to acquire ballistic missiles in the early stages of flight., and

{{Main |Space Tracking and Surveillance System}}

In 2001, the Missile Defense Agency assessed the programs needed for a national ballistic missile defense system (BMDS) and found that they were lacking in the relatively new arena of space. The MDA decided to absorb the SBIRS Low constellation in its very early stages of development and renamed the program the [[Space Tracking and Surveillance System]] (STSS). This transition changed the direction of the program somewhat, but the overall mission remained the same—detectionsame — detection and tracking of ballistic missiles through all of its phases of flight.
