RAF Typhoon FGR4s have joined forces with French warplanes in a joint strike on an hidden munitions depot in Syria employed by the Islamic State group (IS), as stated by the UK's MoD.
The location, identified by surveillance, was believed to be containing munitions and bombs, the announcement noted, and was positioned in mountains just north of Palmyra in the heart of Syria.
"Our fighter planes utilized Paveway IV guided bombs to target a several entry passages providing entry to the site... preliminary assessments suggest the strike was effective," the MoD said.
There was no indication of any civilian impact in the attack conducted Saturday night and every plane involved returned safely, the MoD added.
The British jets were backed up by a Voyager refuelling tanker.
Daesh - also known as the so-called Islamic State - enforced extremist governance over significant areas in Iraq and Syria before its territorial defeat in 2019.
"This action demonstrates the UK's leading role, and commitment to operate in unison with our allies, to eradicate any re-emergence of the terrorist group and their dangerous and violent ideologies in the area," the British Defence Secretary the minister said.
RAF aircraft have carried out surveillance missions over Syria to "deter any attempted resurgence" of Islamic State after its defeat at the battle of Baghuz in 2019, the MoD reported.
"I extend gratitude to the personnel of the UK armed forces participating in this mission for their skill and their bravery," he commented. "They were among thousands of British personnel deployed over the holidays. This mission, to eliminate dangerous terrorists who pose a risk to our way of life, shows how our armed forces are always on standby, all year round, ensuring Britain's security within its borders and powerful internationally."
In December, the American forces executed what it termed a "massive strike" on Islamic State objectives in Syria, subsequent to an attack resulted in the deaths of two American soldiers and a civilian linguist in the Palmyra area.
The UN estimates IS still maintains an estimated 5,000 to 7,000 militants in both countries.
