BV 222 Wiking (Viking) & BV 238
One of World War II’s largest flying boats was the Blohm & Voss BV 222 Wiking (Viking), with six Junkers Jumo 207C 6-cylinder 2-stroke diesel fueled engines of 1000 hp each, was produced in the limited quantity of only thirteen. Originally designed as an airliner, the Wiking was noted for its extremely long as well as flat main cabin floor—novel at the time. The militarized version was powered by diesel engines so the aircraft could be refueled at sea by U-boat and was heavily armed with 3 x 20mm cannon and 5 x 13mm machines guns for defensive measures. Crew number eleven to fourteen on missions ranging from transporting as many as 92 troops, 72 litter cases or over 30,000 pounds of cargo. The Wiking’s cruise speed was 186–214 mph (dependent upon altitude) for 3500+ miles. Though a few survived the war sadly none survived much longer, being scrapped or sunk.
A single larger cousin to the BV 222 was manufactured—the BV 238. It did not survive WW II as it was destroyed to ensure Nazi staff could not use it for escape to far away lands. Each of the six engines was twice the power of each of the BV 222 engines and the gross take weight just over twice that of the Wiking’s though range as well as speed were nearly the same.
