RAF Typhoon FGR4s have operated alongside French warplanes in a joint strike targeting an hidden munitions depot in Syrian territory employed by the Daesh militant organization, as stated by the UK Ministry of Defence.
The facility, identified by surveillance, was believed to be storing arms and explosives, the release indicated, and was positioned in mountainous terrain just north of Palmyra in the heart of Syria.
"Our aircraft utilized Paveway IV guided bombs to hit a number of access tunnels providing entry to the depot... preliminary assessments suggest the strike was effective," the MoD said.
There was no evidence of any civilian impact in the attack late on Saturday and all the aircraft returned safely, the MoD added.
The Typhoon FGR4s were backed up by a Voyager refuelling tanker.
The Islamic State group - also known as the so-called Islamic State - imposed extremist governance over large swathes of Iraq and Syria prior to its 2019 collapse.
"This strike shows the UK's leading role, and determination to work closely with our allies, to eradicate any resurgence of IS and their violent and radical beliefs in the region," UK Defence Secretary the minister remarked.
British military aircraft have performed surveillance missions over Syria to "deter any attempted resurgence" of Islamic State after its military defeat at the battle of Baghuz in 2019, the ministry said.
"I want to thank every member of the UK armed forces participating in this operation for their professionalism and their valour," he added. "Including them were numerous British personnel deployed over the festive period. This mission, to eliminate militants who pose a risk to our security, shows how our armed forces are prepared to act, throughout the year, ensuring Britain's security within its borders and powerful internationally."
During December, the American forces carried out what it called a "major assault" against Islamic State objectives in the country, following an assault claimed the lives of two American soldiers and a civilian linguist in Palmyra.
The U.N. says Daesh still has between 5,000 and 7,000 combatants in both countries.
