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 and to take off from a short ramp. The HD 26 was a conventional biplane with staggered wings, twin float undercarriage, and an open cockpit.
The pattern aircraft supplied by Heinkel was powered by a 300 hp Hispano-Suiza V-8 engine, but the single example of the Aichi Navy Type 2 Single-seat Reconnaissance Seaplane built by Aichi had an Aichi-built 420 hp Bristol Jupiter VI instead. Launching ramps were built on the battleship {{Ship|Japanese battleship|Nagato||2}} and the cruiser {{Ship|Japanese cruiser|Furutaka||2}} for trials, but the HD 25 and HD 26 were already obsolete.Mikesh, Robert and Shorzoe Abe.
