Royal Air Force Typhoon FGR4s have operated alongside French warplanes in a coordinated attack on an hidden munitions depot in Syrian territory used by the IS group, as stated by the UK's MoD.
The site, pinpointed through reconnaissance, was assessed as storing arms and explosives, the statement said, and was located in mountainous terrain just to the north of the historic site of Palmyra in the heart of Syria.
"Our aircraft used Paveway IV guided bombs to strike a several entry passages providing entry to the facility... preliminary assessments suggest the strike was effective," the ministry announced.
There was no sign of any civilian impact in the strike on Saturday evening and all the aircraft returned safely, the ministry further stated.
The British jets were assisted by a Voyager tanker plane.
The Islamic State group - alternatively referred to as Daesh - enforced jihadist rule over significant areas in Syria and Iraq before its territorial defeat in 2019.
"This action underscores our UK leadership, and determination to operate in unison with our allies, to eradicate any re-emergence of Daesh and their harmful and extremist ideologies in the Middle East," UK Defence Secretary the minister stated.
British military aircraft have conducted surveillance missions over Syrian airspace to "deter any attempted resurgence" of Islamic State subsequent to its military defeat at the Baghuz confrontation in the year 2019, the authorities noted.
"I want to thank the personnel of British forces involved in this strike for their professionalism and their valour," the Defence Secretary added. "They were among numerous British troops stationed over the festive period. This mission, to take out terrorist threats who pose a risk to our way of life, highlights how our armed forces are always on standby, continuously, ensuring Britain's security domestically and influential overseas."
Last December, the United States armed forces conducted what it termed a "large-scale strike" on Daesh sites in the country, subsequent to an attack resulted in the deaths of two US servicemembers and a civilian linguist in Palmyra.
The United Nations says IS still boasts an estimated 5,000 to 7,000 combatants in Iraq and Syria.
