Ukraine's air force has acquired Mirage 2000-5 fighters, with reports suggesting four jets have been in operation for over a year. The country may be expanding its fighter fleet, with potential additions including the Dassault Rafale, F-16, and Gripen, although the specifics of these plans are unclear. The Mirage 2000-5s are being used in combat against Russia, and may be used for ground strikes in addition to air defense.
