The Czech Republic

is set to transfer an unknown number of L-159 subsonic fighter jets to Ukraine, to be used for drone interception. Czech President Pavel detailed the plan, which would include the purchase of part of the Czech Republic's fleet, using funds from the $105 Billion usd loan Europe is set to extend Ukraine starting in April.
It's likely that Ukraine would receive 4-6 units initially and if proven highly capable, they may purchase more units at a later time. The L-159 is actually a fighter trainer and it travels at over 900 KPH. The Czechs feel that it is a much cheaper alternative to Ukraine's F-16 fleet, for airborne air defense. The L-159 can be equiped with a suite of NATO standard missiles and rockets, ideal for drone interception, especially CRV7 and Hydra-70 rockets. As Russia continues to build higher numbers of jet powered Shaheds, some of Ukraine's rudimentary ground based air defense systems have proven less capable of shooting them down, forcing Ukraine to use a higher volume of precious missiles such as AIM-9, AIM-120, AIM-132, IRIS-T, SAMP/T and even Patriot. Those missiles need to be saved for the interception of cruise and ballistic missiles, as they're both expensive and replenished at a much slower pace. Increasingly, Ukraine is turning to much cheaper rockets for interception, however, forcing Ukraine's F-16s into that role is a waste of capable air assets. Allowing the L-159 to start backfilling Ukraine's attack helicopter fleet and the quickly disappearing SU-25, would go a long way to retaining the capabilities that those air frames add.
