At the end of February, Yuriy Ignat, who then held the position of representative of the Air Force Command of the Ukrainian Armed Forces, informed that Ukraine was experiencing a shortage of missiles for Western air defense systems and was holding discussions with partners regarding the replenishment of anti-aircraft missiles. In November 2023, he reported that Washington, together with Kiev, was modifying Soviet-made air defense systems to use American missiles in the face of a lack of Western systems. Ignat noted that this is a forced and temporary step that should help strengthen the Ukrainian air defense system until more Western air defense systems, such as NASAMS, IRIS-T, and Patriot, are transferred to Kyiv.
