The Maryland and Pearl Harbor
Maryland was one of eight battleships present in their dour, battleship grey color camouflage scheme at the US Navy anchorage in Pearl Harbor on the morning of December 7, 1941. In a strike that would go a long way towards establishing the aircraft carrier as the queen of the seas, not to mention throw American pre-war plans to the four winds, the US Pacific Fleet was crippled and every battleship docked in Pearl Harbor damaged or sunk.
More than three hundred carrier aircraft armed with torpedoes and bombs tore into the pride of the US Navy, and before the day was done the USS Arizona had taken a bomb to her magazines and blown up, the USS Oklahoma suffered numerous torpedo hits that capsized her, USS California had sunk, USS Nevada had been beached to avoid sinking, and Maryland's sister, West Virginia, had been sent to the bottom as well.
Maryland herself got away with relatively minor damage - she benefited from being tied up inboard of Oklahoma and this protected her from torpedo hits. Her anti-aircraft batteries, such as they were, were brought into action relatively quickly and she helped down some of the few Japanese airplanes to be destroyed that day. But though she was well protected from torpedoes, two bombs struck her and caused serious damage to her superstructure. Good damage control kept her fighting, and in the aftermath of the attack she was one of the ships able to send damage control parties to assist other damaged vessels.
The catastrophic defeat of Pearl Harbor did offer an upside for Maryland. Damaged to the point that she needed a couple months of repair in a fully equipped naval yard, she escaped relatively unscathed relative to the Arizona, Oklahoma, or even her sister West Virginia. Though the latter was eventually raised from the bottom of Pearl Harbor, hastily patched up, and sent to Seattle for reconstruction, she did not return to service until mid-1944. Maryland, by contrast, was back in action by March of 1942- even after she had been significantly refitted to better cope with the demands of the Pacific Fleet.
