W.33

Ordered in April 1918, the W.33 was basically a larger and more powerful development of the W.29 and, augmenting the smaller fighter seaplane, saw service from North Sea air stations during the closing months of World War I.


The W.33 was powered by a 260hp Mb IVa six-cylinder inline water-cooled engine and armament normally comprised two forward-firing 7.62mm LMG 08/15 machine guns and one Parabellum in the rear cockpit. One aircraft was experimentally fitted with a 20mm Becker cannon in the rear cockpit, and several aircraft were fitted with radio and had one of the LMGs removed.


At least six of an initial order of 26 W.33s had been taken into the German Navy's inventory when hostilities terminated, but the Norwegian Naval Flying Boat Factory built 30 under licence and the Norwegian Army Aircraft Factory built a further 11.

The Finnish Aviation Force's Aircraft Factory assembled two W.33s as pattern aircraft in 1922, and licence-manufactured a further 120 during 1923-26. Two were sold to Latvia. Finnish manufactured planes were powered by 300 hp Fiat A-12bis motors.
