[[British Aerospace]] (BAe) licensed the AIM-7E-2 technology in the 1970s, producing the '''Skyflash''' missile. Skyflash used a Marconi XJ521 monopulse seeker together with improvements to the electronics. It was powered by the Aerojet Mk52 mod 2 rocket engine (later by the Rocketdyne Mk38 mod 4). Skyflash entered service with the [[Royal Air Force]] (RAF) on their [[McDonnell Douglas Phantom in UK service|Phantom FG.1 & FGR.2]] in 1978, and later on the [[Panavia Tornado ADV|Tornado F.3]]. Skyflash was also exported to Sweden for use on their [[Saab 37 Viggen|Viggen]] fighters.

An upgraded version with active radar seeker called '''Active Sky Flash''' was proposed by BAe and [[Thomson-CSF]], but the RAF opted to procure [[AIM-120 AMRAAM]] instead.<ref>{{cite web |title=Skyflash |url=https://fas.org/man/dod-101/sys/missile/row/skyflash.htm |website=FAS |access-date=4 November 2018 |archive-url=https://web.archive.org/web/20070313033117/https://fas.org/man/dod-101/sys/missile/row/skyflash.htm |archive-date=13 March 2007 |date=21 March 1999}}</ref>
