KMS O Class Barbarossa 

​O Class Design Brief 

​The O class was a planned class of three battlecruisers for the Kriegsmarine (German navy) before World War II. Prompted by a perceived lack in ship numbers when compared with the British Royal Navy, the O class' design was born with the suggestion of modifying the P-class cruiser design with 380 mm (15 in) guns instead of 283 mm (11.1 in).

The ships were incorporated into the 1939 Plan Z for the re-equipment and expansion of the Kriegsmarine; while an aircraft carrier, H-class battleships and smaller ships engaged convoy escorts, one or more O-class ships would attack the merchant ships.

The O class' design reflected their intended role; a heavy main armament (six 380 mm guns in three dual turrets) for possible encounters with escorting 203 mm (8 in)-armed heavy cruisers, enough armor to defend against the same and nothing more, and a high top speed so that they could get away from slower but much better armored capital ships.

Although planned and ordered, construction did not progress due to lack of materials and higher priorities for ship construction.
