According to Drew Hinshaw in The Wall Street Journal on May 23, the Czech Republic has donated attack helicopters to Ukraine, and along with Slovakia, has allowed Ukraine’s army to send armored vehicles across their borders for repairs before they are returned to the conflict.
The Mil Mi-24V gunships (actually, Mi-35, the export version of the Mi-24V) donated by the Czech Republic were deployed to Ukraine in recent weeks, part of a broader effort to help the country reclaim parity in its own airspace, Drew Hinshaw writes. U.S. Defense Secretary Lloyd Austin thanked the Czechs for their donation during public comments after a meeting of allied defense officials on May 23. The gifts make the Czech Republic—which in April became the first NATO country to report donating tanks to Ukraine—the first to give Ukraine attack helicopters as well.
The Mi-35 (export version of the Mi-24V) was manufactured by the Rostvertol company based in Rostov on Don. The Czech Air Force got Mi-35s with several of its upgrade packages.
