Hetman Sahaydachniy joined the Naval Force of the European Union (EUNAVFOR) in early January 2014 for anti-piracy operations. As she refueled in Greece, while Russian forces seized control of Crimea, Russian Senator Igor Morozov claimed on 1 March 2014 that the ship's crew had defected to Russia and raised the Russian flag. Shortly afterwards, independent news organizations reported that the ship was still flying the Ukrainian flag in port in Crete. The commander of the ship confirmed that the crew had never defected to the Russians. It arrived in Odessa under the Ukrainian flag on March 5. On 14 March, the ship encountered a Russian naval group in Ukrainian territorial waters. As Hetman Sahaydachniy approached the group, they withdrew into international waters. In September, the frigate entered Odessa to undergo repairs.
