The Grigorovich MU-2 was a trainer flying boat built in the Soviet Union in the mid-1920s. It was designed by the Grigorovich Design Bureau after the failure of the Grigorovich MUR-1, featuring an all-metal hull. However, it was never put into production due to poor performance and sluggish take-off behavior.[1]
