H40A to H44
Studies, not additional ships
These concepts were continuations of the H-class design process. They are grouped separately from the six ordered H39-class ships because most remained theoretical studies and were never construction orders.
Design evolution
From H39 to H44
The wartime studies grew from an enlarged Bismarck successor into immense theoretical designs focused on protection against increasingly powerful weapons.
