USA-224, also known as NROL-49, is an American reconnaissance satellite. Launched in 2011 to replace the decade-old USA-161 satellite, it is the fifteenth KH-11 optical imaging satellite to reach orbit.

Project history and cost

After the Boeing-led Future Imagery Architecture program failed in 2005, the National Reconnaissance Office ordered two more KH-11s. Critics worried that each of these "exquisite-class" [2] satellites would cost more than the Navy's latest aircraft carrier (US$6.35 billion in 2005, or about $9,510,000,000 today [3] ). [4] [5] Instead, USA-224–the first of these two–was completed by Lockheed $2 billion under the initial budget estimate and two years ahead of schedule. [6]

Launch

USA-224 was launched atop a Delta IV Heavy rocket from Vandenberg AFB Space Launch Complex 6 in California. The launch was conducted by United Launch Alliance, and was the first flight of a Delta IV Heavy from Vandenberg. [7] Liftoff occurred on 20 January 2011 at 21:10:30 UTC. [8] Upon reaching orbit, the satellite received the International Designator 2011-002A. [9]

The satellite began operating 33 days after its predecessor, USA-161, stopped doing its primary mission. This coverage gap was much smaller than originally feared, thanks to USA-224's earlier-than-planned launch and operational changes to extend the lifetime of USA-161. [6]

As the fifteenth KH-11 satellite to be launched, USA-224 is a member of one of the later block configurations occasionally identified as being a separate system. Details of its mission and orbit are classified, but amateur observers have tracked it in low Earth orbit. Shortly after launch it was in an orbit with a perigee of 251 kilometres (156 mi), an apogee of 1,023 kilometres (636 mi) and 97.9 degrees of inclination, typical for an operational KH-11 satellite. [10] By April it was 260 by 987 kilometres (162 by 613 mi) at 97.93 degrees. [11]

On 30 August 2019, President Donald Trump tweeted a classified picture [12] from an intelligence briefing showing the aftermath of an accident that apparently occurred during launch preparations of a Safir rocket at the Imam Khomeini Spaceport a day earlier. [13] [14] [15] According to analysts, the photo is likely to have been taken by USA-224. [16] [17] The opinion is based on a close agreement between the estimated time when the photo was taken (based on the orientation of shadows cast by structures in the photo), and the location of the satellite at that same time, as estimated with tracking data maintained by the amateur satellite watching community. [18] [19] [20] The off-nadir photograph stands out for its high-resolution (estimated by analysts to be 10 cm or less per pixel), sharpness and lack of atmospheric distortion. [16] Before this tweet, the only KH-11 imagery available was leaked in 1984, [17] and the only declassified imagery available in public domain was released in 2011 taken by KH-9. [20]

The National Reconnaissance Office (NRO) is a member of the United States Intelligence Community and an agency of the United States Department of Defense which designs, builds, launches, and operates the reconnaissance satellites of the U.S. federal government, and provides satellite intelligence to several government agencies, particularly signals intelligence (SIGINT) to the NSA, imagery intelligence (IMINT) to the NGA, and measurement and signature intelligence (MASINT) to the DIA. The NRO announced in 2023 that it plans within the following decade to quadruple the number of satellites it operates and increase the number of signals and images it delivers by a factor of ten.

The Delta IV was primarily a launch vehicle for United States Air Force (USAF) military payloads, but was also used to launch a number of United States government non-military payloads and a single commercial satellite.

GEM is produced by Northrop Grumman Space Systems. GEM boosters are used on the Atlas V and were previously used on the Delta II, Delta III, and Delta IV launch vehicles. A new variant, the GEM 63XL, flew as part of the Vulcan Centaur launch vehicle on 8 January 2024.

Space Launch Complex 6 at Vandenberg Space Force Base in California is a launch pad and support area. The site was originally developed starting in 1966, but no launches occurred until 1995, as it was repurposed sequentially for three programs that were subsequently cancelled. Initially to be used for Titan IIIM rockets and the Manned Orbiting Laboratory, these were cancelled before construction of SLC-6 was complete. The complex was later rebuilt to serve as the west coast launch site for the Space Shuttle, but went unused due to budget, safety and political considerations. The pad was subsequently used for four Athena rocket launches before being modified to support the Delta IV launch vehicle family, which used the pad for ten launches from 2006 until 2022. The last Delta IV launched in September 2022, and SpaceX leased SLC-6 in 2023 to convert it to launch Falcon 9 and Falcon Heavy starting in 2025.

FIA has been called by The New York Times "perhaps the most spectacular and expensive failure in the 50-year history of American spy satellite projects." Despite the optical component's cancellation, the radar component, known as Topaz, has continued, with four satellites in orbit as of February 2016.
