Heinkel He 170

The Heinkel He 170 was a German twin‑engine, low‑wing monoplane developed in the mid‑1930s as a fast utility and reconnaissance aircraft. Designed by Ernst Heinkel’s team, the prototype first flew on 16 November 1934, and the type entered series production the following year. Powered by two Argus As 10 air‑cooled inverted V‑8 engines delivering 240 hp each, the He 170 achieved a top speed of about 460 km/h (286 mph), making it one of the fastest light aircraft of its era. Its retractable undercarriage, all‑metal stressed‑skin construction, and streamlined fuselage contributed to its high performance. The aircraft served primarily with the Luftwaffe’s observation, liaison and training units, and several were adapted for photographic reconnaissance and light transport duties. Although it never saw combat as a front‑line fighter, the He 170’s aerodynamic efficiency and reliable handling informed the design of later Heinkel models, most notably the He 219 night fighter. In the broader context of aviation history, the He 170 demonstrated the potential of twin‑engine monoplane layouts for rapid, versatile operations, influencing post‑war civilian and military aircraft development. Its relatively low production numbers—only about 300 were built—made it a rare but valuable example of pre‑war German engineering, and surviving examples can be found in several museums today.
