Slovakia has relied on its neighbours for airspace protection since last September while it waits for new, U.S.-made F-16 fighters due in 2024.

"We confirmed the interest of the Hungarian side, and Slovakia's gratitude, that it will join in protecting Slovakia's airspace," Nad said in a news conference with his Hungarian counterpart Kristof Szalay-Bobrovniczky, shown on his Facebook page.

Slovakia grounded the ageing MiGs as it embarked on a modernisation programme. It has considered sending them to Ukraine as it battles Russia's invasion but has not made a decision.
