Direct proof of use
The clearest direct public confirmation came from UK Foreign and Commonwealth Office evidence to Parliament in March 2016. That evidence stated that UK-built and licensed Typhoon and Tornado aircraft from the Royal Saudi Air Force had been deployed on combat missions in the Yemen campaign, and that UK-sourced Paveway, Dual Mode Brimstone, and Storm Shadow weapons had also been used.
The same evidence described UK support arrangements for Saudi Typhoon and Tornado fleets, including aircraft deployed on operations over Yemen and Syria, while saying UK personnel were not permitted or required to participate in those operational sorties.

Timeline
Saudi-led air operations began on 26 March 2015 after President Abdrabbuh Mansur Hadi requested intervention. Washington Institute analysis of the opening campaign described about 170 strike aircraft taking part, including about 100 Saudi aircraft, mostly F-15S and Eurofighter Typhoon aircraft.
By March 2016, the UK government had publicly confirmed Royal Saudi Air Force Typhoon combat missions in Yemen. On 13 September 2017, a Saudi Typhoon crashed in Abyan governorate during a combat mission against Houthi fighters, providing a later incident-level datapoint for continued operational use.

Narrative
In Yemen, the Typhoon appeared as a Royal Saudi Air Force fast-jet strike aircraft within the Saudi-led coalition air campaign. The available public evidence supports coalition combat-mission use and air-campaign participation, but it usually does not identify a Typhoon as the platform for individual airstrike incidents.
Open-source accounts describe the Saudi air package as built around F-15S and Eurofighter Typhoon aircraft, with Typhoon and Tornado aircraft linked by UK government evidence to combat missions and UK-sourced precision weapons. Action on Armed Violence similarly summarized the Royal Saudi Air Force's main airframes over Yemen as including the Eurofighter Typhoon, Panavia Tornado, and F-15SA fast jets, armed with a mix of guided bombs and missiles.
The September 2017 Abyan crash report identified the lost aircraft as a Royal Saudi Air Force Typhoon involved in a combat mission against Houthi fighters. That report supports operational presence in southern Yemen, but it does not independently establish a specific target struck by that aircraft before the crash.
