The Heinkel HE 1 was an early single-engine biplane floatplane designed by Ernst Heinkel and built by Caspar-Werke in 1923. It was one of Heinkel's first aircraft designs and established his focus on seaplanes and naval aircraft.

Spot it by:

A biplane floatplane of conventional 1920s layout with twin main floats, equal-span wings with strut bracing, and a radial or inline tractor engine. Distinguished from contemporaries mainly by its Heinkel design provenance.

History

Working initially through Caspar-Werke before establishing his own company, Ernst Heinkel produced the HE 1 in 1923 as a reconnaissance and patrol floatplane. The design showed Heinkel's early competence with seaplane aerodynamics and construction. It led directly to a succession of progressively refined Heinkel floatplane designs through the 1920s.

Variants

The HE 1 was the baseline design; subsequent Heinkel seaplanes (HE 2, HE 4, HE 5) built on its lessons.

Where you'll see it

Evaluated for naval use in the early 1920s; exact operational service details are limited given the constraints on German aviation under Versailles.
