KYIV, Ukraine – Ukraine’s President Volodymyr Zelenskyy has fired the country’s popular defense minister, who pushed for innovation in the battlefield through the use of drones and turned the tables on Russia.

Mykhailo Fedorov, who served as Ukraine’s defense minister for six months, was dismissed as part of a government reshuffle.

Parliament has already approved Zelenskyy’s choice for prime minister, Serhii Koretskyi, former CEO of Naftogaz, the country’s largest oil and gas company. Lawmakers must also approve Fedorov’s replacement.

The defense minister’s dismissal came just hours after Ukraine signed deals with the European Union to boost drone production. Last week, President Trump agreed during NATO’s summit in Turkey to grant Ukraine the licence to produce missiles for the U.S.-made Patriot defense system to defend against Russia’s ballistic missiles.

Speaking to reporters in Kyiv, Fedorov said he was proud of what his team had accomplished in just six months. He said he had received supportive messages from other defense ministers as well as the leaders of tech giants, including Alex Karp of Palantir, who offered him a job that he turned down.

“I don’t need to be Minister of Defense just to be Minister of Defense,” he said. “I need this position so we can win this war.”

There was no immediate comment from Zelenskyy’s office.

Oleksandr Merezhko, a lawmaker with Zelenskyy’s party, told NPR Zelenskyy fired Fedorov because the 35-year old minister clashed with old-school military generals and due to his controversial reforms on military conscription.

During Fedorov’s tenure as the defense minister, Ukraine saw a dramatic improvement of its position in the battlefield, including his push for innovative use of Ukraine’s cutting edge drones in warfare.
