In the late 1930s the Morski Dywizjon Lotniczy (MDLot) needed a new flying boat or large seaplane to replace its aging Latham H43s. Through Fokker, its agent in Europe, Consolidated were able to impress the MDLot with its new Model 28 flying boat. After negotiations the MDLot placed an order for 6 Model 28-4 aircraft, with deliveries arranged from July 1939.
3 aircraft had been delivered by the outbreak of war, and all three were thrown into operations against the invading Germans. 1 was lost at its moorings at Puck, while a second was shot down by the guns of the German destroyer
Leberecht Maass. The third aircraft was able to escape Poland, reaching sanctuary in Sweden, carrying an overload cargo of escaping naval personnel and their families. The aircraft was interned and later was taken into Swedish service.
