 The last remaining pro-GNA Mirage F1ED fighter jet was not airworthy as of 2017 and was put in storage by the pro-GNA forces, as it lacked a functional engine due to lack of spare parts.The main work by the Ukrainian specialists was done on the GNA fleet of light attack aircraft—after the fall of Gaddafi, Dawn of Libya forces possessed five G-2 Galeb and 2 L-39ZO Albatros light attack and trainer aircraft, and during 2015 a further 12 L-39ZO Albatros light attack aircraft were restored and brought back to service by the Ukrainians.During 2015, all 14 operational and combat capable pro-GNA L-39ZO and G-2 fighter jets, as well as two Mi-24 combat attack helicopters, were stationed at the Misrata air force base, and conducted air strikes against both ISIL militants and pro-LNA forces throughout the entire spring of 2015.
