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.
