Royal Air Force Typhoon FGR4s have operated alongside French aircraft in a coordinated attack targeting an underground arms cache in Syria operated by the Islamic State group (IS), as stated by the UK's MoD.
The facility, pinpointed through intelligence, was thought to be storing arms and explosives, the announcement noted, and was situated in hills just to the north of Palmyra in central Syria.
"The RAF jets utilized precision-guided Paveway IV munitions to target a number of entry passages down to the depot... preliminary assessments indicate the objective was successfully hit," the ministry announced.
There was no indication of any civilian impact in the attack on Saturday evening and all the aircraft made a safe return, the defence officials confirmed.
The British jets were backed up by a Voyager tanker plane.
IS - also known as ISIS - imposed jihadist rule over large swathes of Syria and Iraq prior to its 2019 collapse.
"This operation shows British leadership, and resolve to work closely with our partners, to eliminate any revival of the terrorist group and their harmful and extremist ideologies in the area," Britain's Defence Chief John Healey said.
RAF aircraft have performed patrols over Syrian airspace to "forestall any efforts to regroup" of IS subsequent to its defeat at the climactic battle in Baghuz in 2019, the MoD reported.
"I must thank the personnel of our armed forces involved in this operation for their expertise and their valour," Healey commented. "Including them were thousands of British troops on duty over the holidays. This mission, to take out militants who endanger our safety, demonstrates how our armed forces are prepared to act, throughout the year, protecting the UK within its borders and powerful internationally."
In December, the US military carried out what it described as a "massive strike" on Islamic State objectives in Syria, after an ambush resulted in the deaths of two American soldiers and a civilian interpreter in the Palmyra area.
The United Nations reports Islamic State still maintains an estimated 5,000 to 7,000 combatants in both countries.
