RAF Typhoon FGR4s have conducted a mission with French aircraft in a combined operation targeting an underground arms cache in Syrian territory employed by the Daesh militant organization, per a report from the UK's MoD.
The site, located using surveillance, was assessed as housing weapons and explosive materials, the statement said, and was situated in hills just to the north of the historic site of Palmyra in the heart of Syria.
"The RAF jets utilized laser-guided Paveway IV weapons to strike a number of approach shafts down to the facility... preliminary assessments are that the target was engaged successfully," officials stated.
There was no sign of any civilian impact in the strike on Saturday evening and all the aircraft made a safe return, the ministry further stated.
The British jets were backed up by a Voyager aerial refuelling aircraft.
Daesh - alternatively referred to as ISIS - enforced extremist governance over significant areas in Syria and Iraq prior to its 2019 collapse.
"This strike shows the UK's leading role, and resolve to work closely with allied nations, to eradicate any re-emergence of the terrorist group and their harmful and extremist ideologies in the Middle East," UK Defence Secretary the minister stated.
British military aircraft have carried out patrols over Syrian airspace to "deter any attempted resurgence" of Islamic State subsequent to its defeat at the climactic battle in Baghuz in 2019, the authorities noted.
"I must thank all the members of our armed forces participating in this operation for their expertise and their valour," the Defence Secretary added. "They were part of thousands of UK service members on duty over the holidays. This operation, to eliminate militants who pose a risk to our safety, demonstrates how UK forces are prepared to act, throughout the year, protecting the UK domestically and powerful internationally."
In December, the US military executed what it described as a "massive strike" against Islamic State objectives in the country, after an ambush claimed the lives of two US troops and a civilian linguist in Palmyra.
The U.N. says Daesh still has an estimated 5,000 to 7,000 combatants in Syria and Iraq.
