Royal Air Force Typhoon FGR4s have operated alongside French aircraft in a joint strike targeting an underground arms cache in Syria operated by the Daesh militant organization, according to the British defence ministry.
The location, located using reconnaissance, was thought to be housing weapons and explosive materials, the announcement noted, and was located in hills just above Palmyra in Syria's central region.
"Our aircraft employed precision-guided Paveway IV munitions to strike a several entry passages down to the facility... preliminary assessments are that the objective was successfully hit," the MoD said.
There was no sign of any harm to civilians in the operation conducted Saturday night and every plane involved made a safe return, the MoD added.
The Typhoon FGR4s were assisted by a Voyager aerial refuelling aircraft.
IS - also known as Daesh - established extremist governance over large swathes of Syria and Iraq prior to its 2019 collapse.
"This action shows the UK's leading role, and commitment to work closely with our partners, to stamp out any re-emergence of Daesh and their dangerous and violent ideologies in the region," the British Defence Secretary the Defence Secretary said.
RAF aircraft have performed overwatch operations over Syria to "prevent any efforts to regroup" of the group subsequent to its defeat at the Baghuz confrontation in 2019, the ministry said.
"I extend gratitude to every member of our armed forces who took part in this operation for their skill and their valour," he commented. "They were among thousands of British troops deployed over the holidays. This action, to take out terrorist threats who pose a risk to our way of life, highlights how UK forces are always on standby, all year round, ensuring Britain's security at home and strong abroad."
In December, the American forces executed what it described as a "large-scale strike" on IS targets in Syria, subsequent to an assault resulted in the deaths of two US servicemembers and a civilian linguist in Palmyra.
The U.N. reports Daesh still has roughly 5-7 thousand militants in Syria and Iraq.
