USA-292 was launched by United Launch Alliance, aboard an Atlas V 551 flying from SLC-41 at the Cape Canaveral Air Force Station (CCAFS). The launch occurred at 10:13 UTC on 8 August 2019,<ref name="SFI20190808">{{cite web|url=https://www.spaceflightinsider.com/organizations/ula/aehf-5-lights-up-the-sky-atop-ula-atlas-v-551/|title=AEHF 5 lights up the sky atop ULA Atlas V 551|publisher=SpaceFlight Insider|date=8 August 2019|access-date=18 May 2021}}</ref> placing the satellite into a Geostationary transfer orbit (GTO) with a perigee of {{cvt|14434|km|nmi}}, an apogee of {{cvt|35250|km|nmi}}, and 9.95° inclination.<ref name="ULA">{{cite web |url=https://www.ulalaunch.com/docs/default-source/launch-booklets/AEHF5_MOB.pdf|title=AEHF-5 Mission Overview|publisher=United Launch Alliance|access-date=18 May 2021}}</ref> The satellite was successfully deployed in this orbit about five and a half hours after launch.
== TDO-1 satellite == Alongside AEHF-5, the U.S. Air Force Space and Missile Systems Center launched an experimental 12U cubesat known as '''TDO-1''' ('''Technology Demonstration Orbiter''', COSPAR 2019-051B, SATCAT 44482).
