The Raytheon Beechjet traces its origins back to the Mitsubishi Diamond 2 bizjet, which Beechcraft acquired the design and production rights to in the mid 1980s. The original Mitsubishi MU300 Diamond 1 flew for the first time in August 1978, powered by two 2500lbs (11.1kN) P&WC JT15D4 turbofans. Only 11 Diamond 2s were built before Beech purchased the design and production rights, resulting in the Model 400 Beechjet.
Beech re-engined the Diamond 2 with P&WC JT15D5 turbofans, developed a new interior, and incorporated a number of other minor refinements. Deliveries of the Beechjet began in June 1986, with low rate production continuing until that model was replaced by the Model 400A, which was delivered from November 1990. |
