Blohm & Voss BV 222 Wiking (Viking) was a large, six-engined German flying boat that was the largest flying boat in operation and the largest seaplane to attain production status during World War II. While sources often refer to it as a "giant" or "mighty" aircraft due to its immense size, the specific nickname "The Giant of the Seas" is not a widely-recognized or official designation, but likely a descriptive phrase used by enthusiasts or modelers. | Aircraft Blueprints Archives
