The Ethiopian Air Force was built in the 1990s during the country’s war with Eritrea. With its aircraft initially piloted by foreigners, the backbone of its fleet was previously comprised of Soviet MiG-23 jets. Today, with a single squadron of around eight fighters, the bulk of its fleet is comprised of Su-27 heavyweight air superiority fighters, of which an estimated 12-16 are in service, according to Military Watch. The MiG-23 is mainly allocated an air to ground role and serves alongside some Su-25 attack jets. Ethiopia also deploys 18 Mi-24/35 attack helicopters, and last year, it was reported that it was deploying Russian manufactured Pantsir S1 air defense combat vehicles, as part of moves to modernize its air defenses.
