in space
US intelligence-related satellite carrying an SBIRS (Space Based InfraRed) sensor and (probably) a commuications payload for use at northern latitudes. Also carries NASA's TWINS-B (Two Wide-angle Imaging Neutral-atom Spectrometers) detector for monitoring the magnetosphere. See also USA-184 (2006-27A/29249). Illustrations of the satellite published by NASA suggest it is spin-stabilised with a de-spun aerial array.

First Advanced Extra High Frequency satellite to replace the Milstar constellation, providing secure communications for the US military and government Commercial launch into geosynchronous transfer orbit by United Launch Alliance at the beginning of a two hour launch window. It's apogee engine failed to operate so the orbit was raised over a fifteen month period using the vehicles's xenon-fuelled ion electric thrusters. Launch delayed from Jul 30. Orbital elements not released by Spacetrack so parameters are based on amateur observation.

Second X-37B space plane - making its first flight. A mission by the first X-37B flight model was undertaken during 2010 and this second flight will refine some of the tests that it undertook. Mission originally planned for 270 days to Nov 30 but, on that day, USAF announced an indefinite extension. 2012 May 30 - USAF let it be known that the X-37B will return to Vandenberg AFB during tthe first two weeks of June, it landed 2012 Jun 16 at 12:48 UTC.

Missile launch detection satellite for the Space-Based Infra Red System with a combination of scanning and staring sensors. The scanning sensor is designed to provide a wide area view in search of missile launches, satellite re-entries and natural terrestrial events, while the staring sensor is designed to observe areas of particular interest with enhanced sensitivity. Two other SBIRS payloads are aboard satellites in Molniya-type HEO with apogees above the northern hemisphere (USA 184 and USA 200). The initial transfer orbit shown below is for the launch vehicle at the time of separation. Later parameters are based on amateur observation and, from 2015, are based on Space-Track data.

450 kg satellite fitted with new electro-optical and infrared reconnaissance sensors designed to supplement data obtained by unmanned aerial systems and high-altitude aircraft operating in Iraq and Afghanistan. The sensors are based on those being demonstrated by TacSat-3 (2009-028A/35001 launched 2009 May 19). One of the imaging devices is derived from the unit designed for use for the U-2 high altitude reconnaissance aeroplane. ORS-1 stands for "Operational Responsive Space-1". Orbital elements not released by Spacetrack so parameters are based on amateur observation.

First Block II Wideband Global SATCOM vehicle, providing communications links for troops in the field. The service area is reported to be the Middle East. A major improvement in the Block II satellites is transmission of airborne intelligence, surveillance and reconnaissance imagery at approximately three times the data rate available through the Block I satellites. Operated jointly by the US DoD and the Australian Department of Defense. Launched at the beginning of a 34 minute window, separated from the launch vehicle at 01:18 UTC. Initial orbit shown is an estimate, by Ted Molczan, for the Delta final stage around the time of satellite separation. Remaing orbital data is based on amateur observations.

The initial orbit is an estimate by Ted Molczan, published through Seesat-L. Remaining orbits are based on amateur observation. There is no catalogue entry for the launch vehicle because it was intentionally de-orbited above the central Pacific Ocean after completing less than one circuit of the Earth.

Second flight of the first model of the USAF/Boeing X-37B space plane. Detailed payload and mission purpose are unknown. Launch by United Launch Alliance an behalf of USAF Rapid Capabilities Office. Landed on the runway at Vandenberg AFB 2014 Oct 17 at 16:24 UTC. The first orbit listed is an estimate by Ted Molczan based on observations from Cape Town by Greg Roberts soon after launch. Element sets were not released by Space-Track so remaining orbits are based on amateur observation.

Second Block II Wideband Global SATCOM vehicle, providing communications links for troops in the field. A major improvement in the Block II satellites is transmission of airborne intelligence, surveillance and reconnaissance imagery at approximately three times the data rate available through the Block I satellites. Operated jointly by the US DoD and the Australian Department of Defense. Lifted off at the beginning of a 30 minute window, separated from the launch vehicle at 01:27 UTC. Launch delayed from May 22 for a combination of weather and technical issues. The initial orbit is an estimate based on data from ULA, geosynchronous entries are based on amateur observation. Expected location - 52°.5 west.

Probably a third generation Satellite Data System government/military communications satellite aimed at geosynchronous orbit. Launch delayed 4 min from originally announced time, reportedly to avoid a possible collision with an object already in orbit. The Centaur stage of the Atlas V was not catalogued - it was intentionally sent toward a destructive re-entry at the end of its first circuit. Any surviving fragments hit the Surface of the Pacific Ocean shortly after 22:00 UTC near 14° north, 175° west.

Flight of USAF/Boeing X-37B space plane. The vehicle is described as a space technology demonstrator and host platform for experimental payloads. This mission also carried a number of small satellite ride share payloads but there is no indication of how or when they were released into independent orbit. Launch was by SpaceX on behalf of the USAF Rapid Capabilities Office. Landed Kennedy Space Center Shuttle Landing Facility 2019 Oct 27 at 07:51 UTC.. Element sets were not released by Space-Track so parameters are based on amateur observation, the final one was calculated by Nico Janssen from radio observations.

Possible first in the fourth generation of the Satellite Data System (SDS) relaying signals from military satellites in low Earth orbit. The NORAD catalogue number for this mission is out of sequence and was probably allocated an unused 'slot' reserved for a satellite or debris item that subsequently did not appear.

Classified US Government payload. Purpose, mission outcome and orbit unknown. Appears to have re-entered the Earth's atmosphere on the day of launch, an event that is unlikely to have been intended. SpaceX reported that the launch vehicle completed its mission as planned. The launch azimuth suggested it was heading for an inclination of about 50°. Originally scheduled for launch 2017 Nov 17 from Kennedy SC but launch delayed (and launch pad switched) because of an issue with a Falcon 9 payload shroud on another mission.

Advanced Extremely High Frequency US military and government communications satellite. Lift-off was 81 minutes into a 120 minute launch window after a delay caused by a fault in an item of ground equipment. Separated from launch vehicle Mar 27, 01:59 UTC. Orbit raised in stages until Apr 6 when all activity ceased until Apr 24. Satellite then resumed orbit raising by frequent operation of a low power thruster.

in space
One of a simultaneously-launched group of twenty one US government imaging reconnaissance satellites. Design is related the SpaceX Starlink V2 mini satellite and provides a hosting platform for a variety of missions, possibly using the Starlink infrastructure for communications. Missions are a step forward from the likes of the single KH-11 concept where a large constellation will provide 24 hour global coverage. Orbit based on amateur observation.

All satellites injected initially into similar orbits at about 300 km altitude.
