President says air force’s new system involves ‘mobile fire groups’ and interceptor drones as he warns of fresh Russian attacks ahead. What we know on day 1,427

Ukraine’s armed forces are introducing a new facet of air defence, made up of small groups deploying interceptor drones, as the country braces for new mass Russian attacks, Volodymyr Zelenskyy said on Monday. Ukraine is still reeling from a wave of Russian strikes earlier this month that knocked out power and heating to thousands of apartment blocks in freezing temperatures, particularly in the capital, and Zelenskyy has repeatedly called for air defences to be strengthened. “There will be a new approach to the use of air defences by the air force, concerning mobile fire groups, interceptor drones and other ‘short-range’ air defence assets,” the Ukrainian president said in his nightly video address. “The system will be transformed.” Zelenskyy announced the appointment of a new deputy air force commander, Pavlo Yelizarov, to oversee and develop the innovation.

Zelenskyy also warned Ukrainians to be “extremely vigilant” ahead of anticipated new Russian attacks. “Russia has prepared for a strike, a massive strike, and is waiting for the moment to carry it out,” he said, urging every region in the country to “be prepared to respond as quickly as possible and help people”. Zelenskyy and foreign minister Andrii Sybiha both warned at the weekend that Ukrainian intelligence had noted Russia was conducting reconnaissance of specific targets, particularly substations that supply nuclear power plants. Ukrainian energy minister Denys Shmyhal said on Monday that he had informed the head of the International Atomic Energy Agency (IAEA) about Russian preparations for more strikes on Ukrainian energy facilities, including those that ensure the operations of nuclear plants.
