'New aircraft-bomber for the navy.' The blunt tower of Ransdorp is seen in the background. Schellingwoude was a good seaplane harbour and Fokker seaplanes could easily get here from the old waterfront factory. Landplanes had to be moved to Schiphol by barge right through the Amsterdam canals until 1950. T-10 struck off charge at Surabaya, Java in 1940. Photo from: Amsterdam City Archives

A Fokker T.IV of the original series, with Lorraine-Dietrich engines and open crew positions, over the Madura Strait, off Java. The T.IV was intended mainly for anti-shipping missions, having an internal bomb bay for four 200-kg bombs; it was difficult to fit bomb doors in the hull of flying boats such as the Dutch navy's Dornier Wals.
