"At about 20:10 on March 25, a radar mark of a Su-27 aircraft had disappeared during a scheduled flight above the Black Sea, 50 km away from Feodosia. An emergency radio beacon was activated in the area at 20:11," the ministry said.
According to preliminary estimates, the aircraft fell in the sea, the Defense Ministry said.
Two aircraft of the Southern Military District’s search and rescue services - an An-26 plane and a Mi-8 helicopter - have been scrambled.
"Adverse weather conditions in the area complicate the search for the pilot," the ministry said.
