variants with their own articles=The Heinkel HD 26 was a reconnaissance seaplane developed in Germany during the 1920s for production in Japan. It was intended as a smaller, single-seat counterpart to the HD 25, to provide a spotter aircraft for warships, to take off from a short ramp since shipboard catapults had not yet been invented. The HD 26 was a conventional biplane with staggered wings, twin pontoon undercarriage, and an open cockpit.

The pattern aircraft supplied by Heinkel was powered by a Hispano-Suiza engine, but the single example built by Aichi based upon it had a radial engine instead. Launching ramps were built on the battleship "Nagato" and the cruiser "Furutaka" for trials, but the advent of the steam catapult made the HD 25 and HD 26 obsolete.
