RAF Typhoon FGR4s have operated alongside France's air force in a combined operation on an hidden munitions depot in Syrian territory employed by the IS group, as stated by the UK's MoD.
The location, located using surveillance, was assessed as housing weapons and explosive materials, the announcement noted, and was situated in mountainous terrain just to the north of the historic site of Palmyra in Syria's central region.
"Our aircraft used precision-guided Paveway IV munitions to hit a several approach shafts providing entry to the site... early reports suggest the target was engaged successfully," the ministry announced.
There was no sign of any civilian casualties in the operation late on Saturday and all the aircraft returned safely, the ministry further stated.
The Typhoon fighters were backed up by a Voyager refuelling tanker.
IS - also known as ISIS - established extremist governance over significant areas in both Syria and Iraq before its territorial defeat in 2019.
"This operation demonstrates British leadership, and commitment to stand shoulder to shoulder with our partners, to eliminate any revival of Daesh and their dangerous and violent ideologies in the Middle East," Britain's Defence Chief John Healey remarked.
RAF aircraft have performed overwatch operations over Syrian airspace to "prevent any attempted resurgence" of Islamic State subsequent to its routing at the climactic battle in Baghuz in 2019, the MoD reported.
"I must thank the personnel of the UK armed forces participating in this strike for their expertise and their bravery," he said. "Including them were numerous British troops deployed over Christmas and New Year. This mission, to remove terrorist threats who endanger our security, shows how British military are always on standby, continuously, keeping Britain secure within its borders and strong abroad."
Last December, the United States armed forces executed what it described as a "massive strike" targeting IS targets in the country, after an assault killed two US troops and a civilian interpreter in Palmyra.
The United Nations reports Daesh still maintains an estimated 5,000 to 7,000 fighters in Iraq and Syria.
