RAF Typhoon FGR4s have conducted a mission with French aircraft in a coordinated attack against an underground arms cache in Syrian territory operated by the Islamic State group (IS), according to the UK Ministry of Defence.
The facility, pinpointed through intelligence, was thought to be containing munitions and bombs, the announcement noted, and was positioned in mountainous terrain just north of the ancient city of Palmyra in the heart of Syria.
"The RAF jets utilized Paveway IV guided bombs to strike a series of approach shafts leading to the depot... preliminary assessments suggest the target was engaged successfully," officials stated.
There was no evidence of any harm to civilians in the operation on Saturday evening and every plane involved returned safely, the MoD added.
The British jets were backed up by a Voyager aerial refuelling aircraft.
IS - alternatively referred to as Daesh - established extremist governance over large swathes of Syria and Iraq until 2019.
"This operation underscores British leadership, and resolve to work closely with allied nations, to eradicate any revival of the terrorist group and their dangerous and violent ideologies in the Middle East," Britain's Defence Chief the Defence Secretary stated.
UK warplanes have conducted overwatch operations over Syria to "forestall any efforts to regroup" of the group following its military defeat at the Baghuz confrontation in 2019, the MoD reported.
"I must thank all the members of the UK armed forces who took part in this mission for their professionalism and their bravery," Healey said. "They were part of a great many British personnel on duty over Christmas and New Year. This action, to eliminate militants who endanger our way of life, demonstrates how UK forces are prepared to act, all year round, keeping Britain secure at home and influential overseas."
During December, the United States armed forces conducted what it termed a "massive strike" on IS targets in the country, after an assault resulted in the deaths of two US troops and a civilian linguist in Palmyra.
The United Nations estimates Daesh still has an estimated 5,000 to 7,000 fighters in Syria and Iraq.
