RAF Typhoon FGR4s have operated alongside French warplanes in a coordinated attack on an subterranean weapons facility in Syria used by the Daesh militant organization, per a report from the UK Ministry of Defence.
The location, pinpointed through surveillance, was believed to be housing weapons and explosive materials, the statement said, and was positioned in hills just to the north of Palmyra in Syria's central region.
"Our aircraft employed laser-guided Paveway IV weapons to hit a several entry passages down to the site... initial indications suggest the objective was successfully hit," the ministry announced.
There was no sign of any harm to civilians in the attack late on Saturday and each participating jet returned safely, the MoD added.
The Typhoon fighters were backed up by a Voyager tanker plane.
The Islamic State group - alternatively referred to as ISIS - enforced jihadist rule over significant areas in both Syria and Iraq prior to its 2019 collapse.
"This operation demonstrates our UK leadership, and commitment to stand shoulder to shoulder with our allies, to stamp out any re-emergence of Daesh and their violent and radical beliefs in the region," UK Defence Secretary the minister said.
UK warplanes have conducted overwatch operations over Syria to "prevent any attempted comeback" of Islamic State subsequent to its routing at the Baghuz confrontation in 2019, the MoD reported.
"I must thank every member of our armed forces involved in this operation for their professionalism and their bravery," Healey added. "They were among thousands of British troops on duty over the festive period. This mission, to remove terrorist threats who endanger our security, highlights how our armed forces are always on standby, all year round, keeping Britain secure domestically and strong abroad."
Last December, the United States armed forces carried out what it described as a "major assault" on Islamic State objectives in Syria, subsequent to an attack killed two US servicemembers and a civilian linguist in the Palmyra area.
The UN reports Daesh still has an estimated 5,000 to 7,000 militants in Syria and Iraq.
