Zelensky's decision to sack his popular defense chief risks fracturing wartime unity as Ukraine's battlefield momentum faces its biggest test since the 2022 invasion.
Ukrainian President Volodymyr Zelensky dismissed Defense Minister Mykhailo Fedorov on Wednesday, removing a popular reformer credited with modernizing the country's military after barely six months in the post. The ouster, confirmed by Fedorov in a Facebook post, triggered plans for street protests in Kyiv and drew sharp criticism from lawmakers and military volunteers who called it a "fatal mistake."
"The appointment of Fedorov to the defense ministry was one of the wisest decisions the president has made. Firing Fedorov will be one of his biggest mistakes," said Maria Berlinska, a prominent Ukrainian military volunteer, in a Facebook post. "It will cost us dearly."
Fedorov, 35, took over the defense ministry in January after serving as deputy prime minister and digital transformation minister since 2019. During his tenure, he persuaded Elon Musk's SpaceX to disable Starlink terminals used by Russian forces, launched a mid-range drone campaign that disrupted Russian logistics up to 100 kilometers behind front lines, and introduced competitive tenders for military equipment purchases from artillery shells to drones. His team listed 22 achievements in his valedictory message.
The dismissal caps a week of upheaval in Kyiv. Prime Minister Yulia Svyrydenko resigned Sunday after a meeting with Zelensky, triggering the full cabinet's resignation. Zelensky has endorsed Serhiy Koretskiy, the former head of state energy giant Naftogaz, as the next prime minister — a pick that signals energy security will be a top priority as Ukraine braces for a third winter of Russian strikes on its power grid.
Why Fedorov lost his job
The immediate trigger was Fedorov's conflict with Ukraine's commander in chief, Gen. Oleksandr Syrskyi, over military mobilization reform. Zelensky told lawmakers at a meeting of his Servant of the People party that he could not choose between the two men and blamed Fedorov for failing to overhaul recruitment, according to Yaroslav Zhelezhyak, an MP with the opposition Holos party.
"Fedorov did only an imitation of reforms, just slides," one MP from the ruling party told POLITICO, speaking on condition of anonymity.
The dispute has been described as a generational clash between a young, tech-savvy manager with a startup background and a traditional military general. Fedorov's efforts to slash corruption in procurement and revamp the tendering process alienated entrenched interests, according to Serhiy Sternenko, an adviser to the Defense Ministry who resigned Wednesday.
"You can't even imagine what streams of funding have been cut off," Sternenko wrote on social media.
What comes next
Zelensky is expected to nominate Interior Minister Ihor Klymenko to replace Fedorov. Klymenko, a former National Police chief who took over the interior ministry after his predecessor died in a helicopter crash in 2023, represents a return to traditional security leadership rather than the tech-driven approach Fedorov championed.
The reshuffle carries risks for Zelensky. Fedorov remains popular among Ukrainians and Western allies who saw his digital-first approach as a model for how a smaller military can outmaneuver a larger adversary. The last time Zelensky faced significant street protests — over a proposal to strip Ukraine's anti-corruption police of powers in 2025 — he reversed course within days.
Ukraine has gained battlefield momentum in recent months, largely halting Russian advances through drone strikes that have sapped supplies of men and equipment to Russia's front lines. Whether that momentum can survive a leadership shakeup at the defense ministry is the question now facing Kyiv and its Western backers.
