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"{{cite web |last=Ray |first=Justin |url=https://spaceflightnow.com/2017/10/15/atlas-5-pierces-the-night-to-boost-national-security-satellite-into-space/ |title=Atlas 5 pierces the night to boost national security satellite into space |work=Spaceflight Now |date=15 October 2017 |access-date=31 August 2019 |archive-url=https://web.archive.org/web/20190831211714/https://spaceflightnow.com/2017/10/15/atlas-5-pierces-the-night-to-boost-national-security-satellite-into-space/ |archive-date=31 August 2019 |url-status=live }} satellites would cost more than the Navy's latest aircraft carrier ({{US$|6.35 billion}} in 2005, or about

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.{{cite web|last=Ray|first=Justin|date=19 January 2011|title=Delta 4-Heavy ready to serve nation from West Coast pad|url=http://www.spaceflightnow.com/delta/d352/padmods/|url-status=live|archive-url=https://web.archive.org/web/20110122114447/http://www.spaceflightnow.com/delta/d352/padmods/|archive-date=22 January 2011|access-date=22 January 2011|publisher=Spaceflight Now}} Liftoff occurred on 20 January 2011 at 21:10:30 UTC.{{cite web|last=Ray|first=Justin|date=23 January 2011|title=Delta 4-Heavy's hush-hush payload found and identified|url=https://spaceflightnow.com/delta/d352/|url-status=live|archive-url=https://web.archive.org/web/20190831153753/https://spaceflightnow.com/delta/d352/|archive-date=31 August 2019|access-date=31 August 2019|work=Delta Launch Report|publisher=Spaceflight Now}} Upon reaching orbit, the satellite received the International Designator 2011-002A.{{cite web|last=Christy|first=Robert|title=Space events - 2011|url=http://www.zarya.info/Diaries/2011.php|url-status=dead|archive-url=https://web.archive.org/web/20121019065644/http://www.zarya.info/Diaries/2011.php|archive-date=19 October 2012|access-date=22 January 2011|work=Zarya}}

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.

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 {{convert|251|km}}, an apogee of {{convert|1023|km}} and 97.9 degrees of inclination, typical for an operational KH-11 satellite.{{cite web|url=http://www.satobs.org/seesat/Jan-2011/0195.html|title=RE: NROL-49 search elements|publisher=SeeSat-L|first=Ted|last=Molczan|date=21 January 2011|access-date=22 January 2011|archive-url=https://web.archive.org/web/20110928141334/http://www.satobs.org/seesat/Jan-2011/0195.html|archive-date=28 September 2011|url-status=live}} By April it was {{convert|260|by|987|km}} at 97.93 degrees.{{cite web|url=http://www.satobs.org/seesat/Apr-2011/0337.html|title=NROL-34: NOSS 3-5 elements|publisher=SeeSat-L|first=Ted|last=Molczan|date=27 April 2011|access-date=31 August 2019|archive-url=https://web.archive.org/web/20150924095609/http://www.satobs.org/seesat/Apr-2011/0337.html|archive-date=24 September 2015|url-status=live}}
