Английская Википедия:Heinkel HD 25
The Heinkel HD 25 was a two-seat shipboard biplane reconnaissance floatplane developed in Germany during the 1920s for production in Japan.
Development
It was intended to provide a spotter aircraft for warships, to take off from a short ramp since shipboard catapults had not yet been developed by the Japanese. The HD 25 was a conventional biplane with staggered wings and twin pontoon undercarriage. The pilot and observer sat in tandem, open cockpits. A single example of a modified demilitarised version was built by Aichi as the AB-1, and three surplus Type 2 Two-seat Reconnaissance Seaplanes were converted with two seat cabins aft of the open rear cockpit, to seat three passengers, for use by the Kouchi Shimbun newspaper.
Operational history
Two prototypes were built by Heinkel in Germany, with the first flying in 1926.[1] Following trials, the Navy officially accepted the type in March 1928 and gave it the designation Type 2 Two-seat Reconnaissance Seaplane. 16 were built by Aichi and saw brief service aboard the cruisers of the Imperial Japanese Navy.
