Mitsubishi Ki-67 Hiryū “Peggy” Technical Manual Collection

A focused collection of five Japanese-language manuals and one English-language photographic collection documenting the Mitsubishi Ki-67 Hiryū, Allied reporting name “Peggy”, the Imperial Japanese Army Air Service’s advanced twin-engine heavy bomber of the Second World War.

The Ki-67 was developed as a powerful departure from Japan’s traditional lightweight, long-range bomber philosophy. Its mid-wing cantilever monoplane layout, streamlined fuselage, self-sealing fuel tanks, robust structure, large balanced control surfaces, and heavy defensive armament supported an aircraft noted for its speed, agility, and low-altitude handling.

Technical and operational reference points

  • Wing area: 65.85 m² (708.8 sq ft).
  • Powerplant: twin Mitsubishi Ha-104 18-cylinder, two-row, air-cooled radial engines with four-blade constant-speed metal propellers.
  • Output: 1,900 hp for takeoff, 1,810 hp at 2,200 m, and 1,610 hp at 6,100 m.
  • Maximum speed: 537 km/h (334 mph) at 6,090 m.
  • Cruising speed: 400 km/h (249 mph) at an operational altitude of 8,000 m.
  • Climb: 6,000 m in 14 minutes 30 seconds.
  • Service ceiling: 9,470 m (31,070 ft).
  • Standard range: 3,800 km (2,360 miles).
  • Payload: 800 kg (1,764 lb) of internal bomb-bay ordnance or one Type 91 centerline aerial torpedo.
