Royal Air Force Typhoon FGR4s have operated alongside France's air force in a coordinated attack against an subterranean weapons facility in Syrian territory used by the Daesh militant organization, according to the UK's MoD.
The site, identified by reconnaissance, was assessed as containing munitions and bombs, the statement said, and was situated in mountainous terrain just north of the historic site of Palmyra in central Syria.
"The RAF jets utilized laser-guided Paveway IV weapons to hit a number of entry passages providing entry to the depot... initial indications indicate the target was engaged successfully," officials stated.
There was no indication of any civilian impact in the attack conducted Saturday night and all the aircraft made a safe return, the ministry further stated.
The Typhoon FGR4s were backed up by a Voyager tanker plane.
IS - alternatively referred to as ISIS - enforced jihadist rule over large swathes of both Syria and Iraq prior to its 2019 collapse.
"This action shows the UK's leading role, and determination to stand shoulder to shoulder with allied nations, to eliminate any re-emergence of the terrorist group and their violent and radical beliefs in the Middle East," UK Defence Secretary the Defence Secretary said.
UK warplanes have carried out surveillance missions over Syrian airspace to "deter any efforts to regroup" of IS after its routing at the climactic battle in Baghuz in 2019, the authorities noted.
"I want to thank all the members of our armed forces involved in this strike for their professionalism and their bravery," he said. "Including them were a great many British personnel on duty over the holidays. This mission, to eliminate terrorist threats who endanger our security, shows how British military are prepared to act, throughout the year, protecting the UK within its borders and strong abroad."
Last December, the United States armed forces conducted what it termed a "massive strike" on Islamic State objectives in the country, after an assault killed two US servicemembers and a civilian linguist in the Palmyra area.
The UN estimates IS still maintains an estimated 5,000 to 7,000 militants in both countries.
