Royal Air Force Typhoon FGR4s have operated alongside French aircraft in a combined operation targeting an hidden munitions depot in Syrian territory operated by the IS group, as stated by the UK Ministry of Defence.
The site, identified by reconnaissance, was believed to be storing arms and explosives, the statement said, and was positioned in hills just to the north of Palmyra in Syria's central region.
"The RAF jets utilized Paveway IV guided bombs to strike a several entry passages leading to the facility... initial indications indicate the strike was effective," the MoD said.
There was no indication of any civilian casualties in the strike late on Saturday and each participating jet returned safely, the defence officials confirmed.
The Typhoon FGR4s were assisted by a Voyager refuelling tanker.
Daesh - referred to as ISIS - imposed militant control over significant areas in Syria and Iraq before its territorial defeat in 2019.
"This strike shows British leadership, and determination to work closely with our allies, to eradicate any revival of IS and their harmful and extremist ideologies in the area," the British Defence Secretary the Defence Secretary stated.
UK warplanes have carried out patrols over Syria to "deter any attempted comeback" of Islamic State after its military defeat at the battle of Baghuz in 2019, the ministry said.
"I want to thank every member of British forces involved in this strike for their skill and their courage," Healey said. "They were part of a great many British troops deployed over Christmas and New Year. This mission, to remove militants who threaten our safety, highlights how our armed forces are prepared to act, all year round, keeping Britain secure within its borders and strong abroad."
In December, the American forces executed what it called a "massive strike" against Islamic State objectives in the country, subsequent to an attack killed two American soldiers and a civilian linguist in Palmyra.
