The Tyne Mk 21/22 turboprop engine, delivering 4,100 kW, powers the Transall military transport and the Breguet Atlantic reconnaisance/anti-submarine warfare aircraft. The commercial version of the Tyne is used in the CL44 Vanguard and Short Belfast freighter aircraft. Until delivery of the TP400-D6, powerplant for the 400M, the Tyne was the most powerful propeller engine of the Western world. 470 Tyne Mk 22 and 315 Tyne Mk 21 were built and assembled at MTU under license from Rolls-Royce from 1966 to 1972.

Today, MTU provides maintenance and repair services for the Tyne. Together with its partners Rolls-Royce, Safran Aircraft Engines and Techspace Aero the company is manufacturing spare parts for the German, French and Turkish Air Forces.
