Royal Air Force Typhoon FGR4s have operated alongside France's air force in a joint strike on an underground arms cache in Syria employed by the Daesh militant organization, as stated by the UK's MoD.
The location, identified by reconnaissance, was thought to be housing weapons and explosive materials, the statement said, and was situated in mountainous terrain just north of the historic site of Palmyra in central Syria.
"Our aircraft employed precision-guided Paveway IV munitions to target a number of entry passages leading to the site... early reports suggest the target was engaged successfully," the ministry announced.
There was no sign of any harm to civilians in the attack on Saturday evening and all the aircraft returned to base without incident, the MoD added.
The British jets were supported by a Voyager refuelling tanker.
IS - alternatively referred to as ISIS - imposed extremist governance over large swathes of Syria and Iraq until 2019.
"This strike demonstrates British leadership, and commitment to work closely with our partners, to stamp out any resurgence of the terrorist group and their dangerous and violent ideologies in the region," UK Defence Secretary the minister remarked.
British military aircraft have carried out overwatch operations over Syria to "forestall any attempted comeback" of IS subsequent to its routing at the Baghuz confrontation in the year 2019, the ministry said.
"I must thank every member of the UK armed forces participating in this mission for their skill and their courage," the Defence Secretary added. "They were part of a great many UK service members deployed over the holidays. This operation, to take out dangerous terrorists who threaten our security, demonstrates how our armed forces are always on standby, all year round, protecting the UK within its borders and strong abroad."
Last December, the United States armed forces conducted what it termed a "massive strike" targeting Islamic State objectives in Syria, following an ambush resulted in the deaths of two American soldiers and a civilian linguist in Palmyra.
The United Nations estimates Islamic State still maintains an estimated 5,000 to 7,000 militants in both countries.
