Bavarian State Police
Perhaps the most successful product produced primarily by MBB Bo 105 helicopter. This rotorcraft, the design of which was headed by German engineer Ludwig Bölkow, made use of a revolutionary hingeless main rotor composed of fibreglass. On 13 October 1970, the German Civil Aviation Authority certified the Bo 105; initial deliveries for the first customers, ADAC Air Rescue and the Bavarian State Police, took place shortly thereafter. During 1972, an improved version of the rotorcraft with more powerful engines, the Bo 105C, was developed, this model quickly superseded the Bo 105A. Following its introduction to service in 1970, the Bo 105 quickly proved to be a commercial success. Production continued until 2001; by the end of production, 1,406 rotorcraft had been manufactured and delivered to operators in 55 nations worldwide. It served as the basis for several derivatives, such as the MBB/Kawasaki BK 117.
