Heinkel HE 2

The Heinkel He 2, produced in Sweden as the Svenska S 3 and nicknamed the "Hansa", was a reconnaissance floatplane built in small numbers to equip the Swedish Navy in the 1920s. It was a refinement of the HE 1, sharing its same basic configuration as a low-wing, strut-braced monoplane with no tail fin and a rudder that barely protruded above and below the line of the fuselage.
Originally, three were purchased, with another one built by Svenska Aero some time later, and a fifth and final aircraft built by the Navy itself. The type remained in service for over 10 years, finally being retired in 1935.
