British Air Force Typhoon FGR4s have conducted a mission with France's air force in a coordinated attack against an subterranean weapons facility in Syria employed by the IS group, as stated by the UK Ministry of Defence.
The location, pinpointed through reconnaissance, was believed to be housing weapons and explosive materials, the statement said, and was positioned in hills just above Palmyra in Syria's central region.
"The RAF jets employed Paveway IV guided bombs to target a number of approach shafts providing entry to the depot... preliminary assessments suggest the target was engaged successfully," the ministry announced.
There was no sign of any civilian impact in the operation late on Saturday and every plane involved returned to base without incident, the defence officials confirmed.
The Typhoon FGR4s were assisted by a Voyager aerial refuelling aircraft.
IS - referred to as ISIS - established extremist governance over significant areas in Iraq and Syria until 2019.
"This action underscores the UK's leading role, and commitment to operate in unison with our partners, to eliminate any resurgence of the terrorist group and their dangerous and violent ideologies in the area," the British Defence Secretary the Defence Secretary remarked.
RAF aircraft have carried out overwatch operations over Syria to "prevent any efforts to regroup" of Islamic State subsequent to its defeat at the Baghuz confrontation in 2019, the ministry said.
"I want to thank all the members of our armed forces participating in this strike for their expertise and their bravery," the Defence Secretary added. "They were among thousands of British personnel stationed over the holidays. This action, to eliminate dangerous terrorists who endanger our security, highlights how our armed forces are prepared to act, throughout the year, keeping Britain secure within its borders and strong abroad."
Last December, the American forces carried out what it termed a "large-scale strike" on Daesh sites in Syria, subsequent to an assault claimed the lives of two US servicemembers and a civilian linguist in Palmyra.
The U.N. reports Daesh still has between 5,000 and 7,000 combatants in Iraq and Syria.
