Oleksiy Vadatursky, founder and owner of agriculture company Nibulon, was killed along with his wife in their home, Mykolaiv Governor Vitaliy Kim said on Telegram on Sunday.
With its headquarters in Mykolaiv, a strategically important city that borders the mostly Russia-occupied Kherson region, Nibulon specialises in the production and export of wheat, barley and corn, and it has its own fleet and shipyard.
Ukrainian President Volodymyr Zelenskyy described Vadatursky’s death as “a great loss for all of Ukraine”, saying the businessman had been in the process of building a modern grain market involving a network of transhipment terminals and elevators.
Three people were also wounded in the attacks on Mykolaiv, the city’s Mayor Oleksandr Senkevych told Ukrainian television, adding that 12 missiles had hit homes and educational facilities. He earlier described the attacks as “probably the most powerful” on the city of the entire five-month-old war.
Up to 50 grad rockets hit residential areas in the southern city of Nikopol on Sunday morning, Dnipropetrovsk Governor Valentyn Reznichenko wrote on Telegram. One person was wounded.
Meanwhile, Ukrainian forces hit Russia’s Black Sea Fleet headquarters in Russian-held Sevastopol early on Sunday, the Crimean port city’s Governor Mikhail Razvozhayev told Russian media. Five staff members were wounded in the attack when what was presumed to be a drone flew into the courtyard at the headquarters, he said.
The battlefield reports could not be independently verified.
Russia’s new naval doctrine
The Sevastopol attack coincided with Russia’s Navy Day, which Russian President Vladimir Putin marked by announcing that the navy would receive what he called “formidable” hypersonic Zircon cruise missiles in the coming months. Those missiles can travel at nine times the speed of sound.
Putin did not mention the conflict in Ukraine during a speech after signing a new naval doctrine that cast the US as Russia’s main rival and set out Russia’s global maritime ambitions for crucial areas such as the Arctic and the Black Sea.

Anatol Lieven, a senior research fellow on Russia and Europe at the Quincy Institute of Responsible Statecraft, told Al Jazeera that despite Putin’s announcement, the Russian navy will struggle to compete with the US and NATO fleets.
