The RC-135U Combat Sent is designed to collect technical intelligence on adversary radar emitter systems. Combat Sent data is collected to develop new or upgraded [[radar warning receiver]]s, [[radar jammer]]s, decoys, [[anti-radiation missile]]s, and training simulators.<ref name="alm08"/>

Distinctly identified by the antenna arrays on the fuselage chin, tailcone, and wing tips, three RC-135C aircraft were converted to RC-135U (63-9792, 64–14847, & 64–14849) in the early 1970s. In 1978, 63-9792 was converted into a Rivet Joint. All aircraft remain in service based at [[Offutt Air Force Base]], Nebraska. Minimum crew requirements are 2 pilots, 2 navigators, 3 systems engineers, 10 [[electronic warfare]] officers, and 6 area specialists.<ref name="cs-factsheet">{{cite web |title=RC-135U Combat Sent factsheet |url=https://www.af.mil/About-Us/Fact-Sheets/Display/Article/104495/rc-135u-combat-sent/ |publisher=United States Air Force |date=28 September 2007 |access-date=10 July 2011 |archive-date=16 February 2016 |archive-url=https://web.archive.org/web/20160216060055/http://www.af.mil/AboutUs/FactSheets/Display/tabid/224/Article/104495/rc-135u-combat-sent.aspx |url-status=live }}</ref>
