The Rohrbach Ro II was an all-metal, 4-seat reconnaissance and bomber flying boat, designed and produced in Germany in 1923.

Adolf Rohrbach, the Rohrbach Metall-Flugzeugbau GmbH designed and built many aircraft using light-alloy stressed skin construction methods that were at the cutting edge of aircraft design in the 1920s.

Planforms and profiles were kept as simple as possible with rectangular section fuselage frames (with vee planing bottoms), constant chord wings, tailplane and fin with square cut tips and distinctive protruding servo/trim/balance tabs at wing and fin tips.

[2] At the time of the Ro II's production the Versailles Treaty forbade the construction of large aircraft in Germany so Rohrbach set up a Danish company, the 'Rohrbach-Metall-Aeroplan Co. A/S', to build the early Rohrbach aircraft.

[2] The first flight of the Ro II took place on 11 November 1923, pilotted by Werner Landmann and the aircraft was used in FAI record attempts for speed/load on 24 October 1924.
