The Beriev Be-10, also known as Izdelye M, (NATO reporting name: Mallow) was a twin engined, turbojet powered, flying-boat, patrol bomber built by the Soviet Union from 1955. The Be-10 is sometimes referred to as the M-10, though this designation is believed to apply only to the modified Be-10 that established 12 FAI world records in 1961, Bort no. 40 Yellow, still holding class records for speed and altitude.
