Tokyo, April 16, 2024 — Kawasaki Heavy Industries, Ltd. announced today the receipt of an order by Shizuoka City for a H145//BK117 D-3 helicopter (hereafter, "D-3"), the newest model in the BK117 series. This will be delivered in March 2026, and used as a firefighting and disaster relief helicopter . This order is the fourth D-3 to be used for firefighting and disaster relief helicopter use, and the twenty-seventh order Kawasaki received overall.

The D-3 has versatile and large rear clam shell doors, large cabin space with a full flat floor, improved hovering performance at high altitudes. These features contribute for smooth emergency transportation and will also be of great use in rescue operations in the high mountain areas, which is one of the characteristics of Shizuoka City. In addition, the D-3 retains the features of the BK117 series such as improved safety performance, reduced pilot load with the state-of-the-art avionics (electronics), while improving performance by using of the latest main rotor system (5-blade main rotor) as follows:

  1. Increase of useful load weight by approximately 150 kg:
    Maximum Takeoff Weight was increased by approximately 100 kg, and the total empty weight was reduced by approximately 50kg, increasing the useful load of the D-3 by approximately 150 kg.
  2. Reduction of maintenance period by approximately 50%:
    A contribution of fewer inspection items and intervals, the adoption of a modern, easy-to-maintain main rotor system.

The BK117 is a medium-sized, twin-engine helicopter developed jointly with European company Airbus Helicopters, and is used for various purposes including firefighting disaster relief, emergency medical services, law enforcement, broadcasting, and personnel and cargo transport. Following delivery of the first model in 1983, this helicopter has been continually improved over the years, and thanks to the aircraft's outstanding technological strengths and high reliability, Kawasaki has successfully delivered 196 units as of today, and more than 1,900 worldwide with deliveries of Airbus Helicopters combined.

Kawasaki will continue to improve the BK117 helicopter, including the development of new optional equipment for various applications.
