President Volodymyr Zelenskyy appointed 34-year-old Fedorov at the start of the year. The former head of Ukraine's digital transformation policies is credited with spearheading the the army's drone technology and introducing several successful e-government platforms.
His appointment was part of a broad government reshuffle that the Ukrainian leader said aimed to sharpen the focus on security, defense development and diplomacy amid a new U.S.-led push to find a peace settlement.
Fedorov said the defense ministry is facing a shortfall of 300 billion hryvnia ($6.9 billion) in funding needs.
The European Union will dedicate most of a massive new loan program to help fund Ukraine's military and economy over the next two years, European Commission President Ursula von der Leyen said Wednesday.
Fedorov said Ukraine's defense sector has expanded significantly since Russia's full-scale invasion in February 2022. At the start of the war, he said, the country had seven private drone companies and two firms developing electronic warfare systems. Today, he said, there are nearly 500 drone manufacturers and about 200 electronic warfare companies in Ukraine.
