Iraqi Su-25s, UAVs grounded because of lack of spares 06 May 2021 by Jeremy Binnie Iraq’s Russian-made Su-25 ground-attack aircraft and Chinese-made CH-4 unmanned aerial vehicles (UAVs) are currently grounded owing to a lack of spare parts, according to a report released by the US Department of Defense’s Office of Inspector General (OIG) on 4 May. Iraq’s Su-25 attack aircraft are now grounded. (Iraqi Ministry of Defence) The report, which reviewed the progress of Operation ‘Inherent Resolve’ (OIR) in Iraq and Syria from 1 January to 31 March, cited the US-led coalition as saying the Su-25s “did not fly during the quarter due to a lack of available parts and funds” and that the CH-4s were last flown in September 2019 because they are awaiting parts from China.
