Heinkel HD 16

The Heinkel HD 16 was a single-engine biplane torpedo bomber designed in the 1920s by the German aircraft manufacturer Ernst Heinkel Flugzeugwerke and later produced under license by Svenska Aero in Stockholm, Sweden.

Development

The HD 16 represented a modified iteration of the earlier Heinkel HD 14 model. Only two units of the HD 16 were constructed and subsequently acquired by the Swedish Navy, where they were designated as T 1. These aircraft were powered by a single Armstrong Siddeley Leopard radial engine featuring 14 cylinders and delivering approximately 666 horsepower. Armament included a Swedish-made m / 17 torpedo, measuring 45 cm in diameter and weighing close to 800 kg, alongside a 7.7 mm machine gun. Initially, the cockpit arrangement placed the pilot and observer seated side by side; however, this was later altered to a tandem configuration to enhance the observer’s field of view.
