Direct proof of use
The IOMAX Archangel appears in the 2014 Yemen Civil War record through reporting on UAE-operated aircraft. Danwatch reported that the UAE received 24 IOMAX Archangels with Terma self-protection equipment in 2015-2017 and said satellite imagery and other material placed Emirati Archangels in several Yemen-war operating areas from 2017 onward.
A separate February 2017 Shephard report said the UAE was considering additional Archangels after successful deployment to Yemen and other regional hotspots. On September 11, 2017, Military Aviation Review reported that a UAE-operated Thrush T-660 Archangel counter-insurgency aircraft crashed off Yemen, killing one crew member; Danwatch later cited the same mission crash as further evidence of Emirati Archangel use in Yemen.

Timeline
The aircraft entered UAE service before the clearest public Yemen-use reporting. AIN reported in June 2015 that the first production Archangel had been accepted for ferry flight to the UAE, and Terma later stated that its MASE pod was fielded on the IOMAX Archangel II within the UAE Air Force.
By February 2017, Shephard described UAE Archangels as already successfully deployed to Yemen and other regional hotspots. On September 11, 2017, Military Aviation Review reported the crash of a UAE-operated Archangel off Yemen. In May 2020, Danwatch published its investigation tying UAE Archangels, Terma equipment, satellite imagery, and the September 2017 Yemen mission crash into a documented Yemen-war use case.

Operational role
The documented operator was the United Arab Emirates, part of the Saudi-led coalition and the catalog side grouped as Yemeni government and coalition forces. The public evidence supports Archangel fielding for the coalition air component in and around Yemen, but it does not provide a public sortie-by-sortie record or identify individual strike targets for the aircraft.
The Archangel's Yemen role fits its marketed armed ISR and light-attack profile. IOMAX describes the aircraft as an armed surveillance platform with electro-optical/infrared targeting and reconnaissance capability, while the Yemen-specific reporting describes UAE Archangels as bombers or counter-insurgency aircraft and links them to operating areas and a mission crash rather than to a single named battlefield engagement.
Danwatch's investigation framed the Terma equipment and UAE use in legal and humanitarian terms, including concerns about possible war crimes. This record does not make an independent legal assessment; it uses the investigation for the narrower factual claims that UAE Archangels with Terma equipment were documented in Yemen-war operating areas and that one UAE Archangel crashed during a Yemen mission.
