W.33 development and licensed production in Norway

The W.33 answered a demand for an aircraft larger than the W.29. Some accounts give Hans Klemm the design credit, although the extent of Heinkel's supervision remains part of the attribution question. Hansa-Brandenburg built twenty-six examples, with only seven complete before the armistice, leaving the German navy little opportunity to use them. Norway's naval aircraft factory built twenty-four for the navy, with Mark II and Mark III versions following the Mark I derived from the W.29. Norwegian army factories also produced aircraft that later passed to the navy when the army no longer required them. Postwar licensed manufacture gave the design a much larger career than its small German production run.
