During WWII, the Douglas DC-3 was indispensable; it was used in every theatre of the war including every action in Europe, Africa and the South Pacific. It was a workhorse, and it was dependable. Our “Under the Radar” this week, mentioned the Japanese Zero and the Grumman Wildcat being converted to floatplanes to assist newly-arrived troops on islands without an airstrip, but miles of ocean beaches and lagoons. Besides needing fighter aircraft to defend their positions, the newly-arrived troops needed replacements and supplies, at a rate faster than boats and barges could supply them. Taking a note from Wildcat and Zero thinking, Douglas in Long Beach, California, was instructed to start producing C-47s (military DC-3s) equipped with amphibious floats. These aircraft were needed so supplies could be picked up at military airports and then flown to the islands where they would land in the water and unload these supplies. The idea had merit, but the newly-organized Seabees were capable of building landing strips in a matter of a few days or even overnight. Thus, float-equipped fighters and transports were not needed.
Edo manufactured at least 30 to 150 sets of floats (depending on who is counting.) Most were sold surplus for scrap, with only a few surviving intact.
The float-equipped C-47 program was aborted after only two were outfitted with the huge EDO amphibious floats. I had read that EDO was reported to have made as few as 32 sets of the C-47 floats and as many as 150 of them.
