A Russian Ka-29 military helicopter crashed in the Baltic Sea in the Kaliningrad region, killing two crew members on board, the Russian Baltic Fleet said Friday.
The helicopter crashed during a nighttime test flight over the Baltic Sea at about 23:30 Moscow time (2030 GMT) on Thursday, according to a statement released by the Baltic Fleet's press service.
Both pilots on board died, it said. A search operation is underway at the crash site.
The Ka-29 is a combat transport helicopter developed by the Moscow-based Kamov Design Bureau, which designs helicopters for Russia's naval fleets. It made its debut flight in July 1976.
