 The following month, the second production example made its foreign debut at the Farnborough Airshow, where it was displayed with an image of a werewolf on its rudder—gaining the popular nickname "Werewolf".The fifth prototype, painted black, played the title role in the movie "Чёрная акула" (Black Shark), which made the Ka-50 known by its current nickname.In November 1993, four production helicopters were flown to the Army Aviation Combat Training Centre at Torzhok to begin field trials.
