First conceived in the mid-1930s, the Type VII submarine was still in production at the end of World War II. Subject to continuous improvement through six major variants and with around 650 completed, it was built in larger numbers than any other submarine design in history and formed the backbone of the Kriegsmarine's U-boat campaign. The book offers comprehensive visual coverage, including full color three dimensional illustrations of every external feature and variant. With its unique concentration of information and illustrative reference, Type VII is unrivaled.
