Royal Air Force Typhoon jets have operated alongside France's air force in a coordinated attack on an hidden munitions depot in Syria employed by the IS group, according to the British defence ministry.
The site, pinpointed through reconnaissance, was assessed as housing weapons and explosive materials, the statement said, and was located in hills just above Palmyra in the heart of Syria.
"Our aircraft used laser-guided Paveway IV weapons to strike a series of entry passages down to the site... initial indications indicate the strike was effective," officials stated.
There was no indication of any civilian impact in the operation late on Saturday and each participating jet returned safely, the defence officials confirmed.
The Typhoon FGR4s were backed up by a Voyager tanker plane.
IS - referred to as ISIS - enforced militant control over large swathes of Iraq and Syria until 2019.
"This action demonstrates the UK's leading role, and resolve to work closely with our allies, to stamp out any revival of Daesh and their harmful and extremist ideologies in the region," the British Defence Secretary the Defence Secretary stated.
UK warplanes have conducted surveillance missions over Syria to "forestall any efforts to regroup" of the group after its military defeat at the climactic battle in Baghuz in the year 2019, the MoD reported.
"I extend gratitude to the personnel of the UK armed forces involved in this mission for their expertise and their bravery," he commented. "Including them were a great many British troops on duty over Christmas and New Year. This operation, to eliminate militants who endanger our security, shows how our armed forces are always on standby, all year round, ensuring Britain's security at home and powerful internationally."
