 The air force of the internationally recognized government could receive some limited supplies of MiG-21s and Mi-8 from the Egyptian Air Force too.Libyan aircraft carried out airstrikes against Islamists during the conflict, but have sustained considerable casualties.The biggest setback for the pro-GNA forces happened on 9 August 2014, when pro-LNA forces captured al-Watiya air force base, where 10 to 12 decommissioned Su-22 bombers, several Mi-25 combat attack helicopters and possibly up to 21 decommissioned Mirage F-1ED fighter jets, as well as all spare parts and weapons for Mirage F-1ED and Su-22 aircraft, were stored there—this defeat crippled the pro-GNA air forces, because now they lost their main source of spare parts for maintaining their Mirage F-1ED fighter jets.
