Probably just going to act like an archive of ship histories
here are some I have made, definitely not complete nor completely detailed. Will add more when have time. You guys can also chip in
Massachusetts: fire upon Jean Bart when the Allies tried to prevent it from being captured and used by German forces after the French surrender. Jean Bart was also attacked by USS ranger planes, and she fought back with a makeshift rangefinder and incomplete aa guns
Jean Bart: French Battleship that had most of its action while incomplete, decommissioned in 1957 and scrapped in 1970’s after finally completed in the 1955
USS ranger was the first aircraft carrier built from scratch as a CV for the USN, with CV-1, Langley, being a converted coal ship. She was supposed to be flat evoked, but later had a island superstructure installed that caused large stability issues. She operated in the Atlantic and took part in Operation Torch (allied invasion of Africa) and the attack on Jean Bart.
Scharnhorst- record holder for one of the longest hits ever made, about 28,000 yard hit on HMS Glorious in 1940 if I remember. She was a famous commerce raider with her sister Gnesiau (spelling) along with She was sunk by torpedo spread by British forces.
Tirpritz - famously painted as a series of residential homes as camoflage, and was hit badly in port by famous 4,000 pound Tallboy bombs from British bombers. One of these bombs missed and is now a pond today lol.
Hood - entered Battle of Denmark strait with only her forward and mid deck/magazine armor reinforced, with her aft deck plates and additional armor package waiting at a shipyard. This delay in the upgrade was due to the need for constant presence of hood as a flagship- very little time to upgrade. She, in sheer bad karma, was sunk by a 15inch shell through the unreinforced aft armor. Bismarck, also in sheer bad karma, will get a lucky torpedo hit by swordfish torpedo bombers (too long of a story).
Vangard- one of the last British battleships ever built, sad to see her scrapped
Alaska- part cruiser part battleship built to counter new Japanese cruisers. 12inch guns, but cruiser like characteristics with radar in game. - no combat experiances
Kii was a modern battleship at time of construction with a archaic ww1 doctrine layout, which favored many dual gun turrets rather than a smaller number of triple or quadruple gun turrets to maintain as much firepower in the even of the turret knockout
USS Colorado: upgunned version of previous standard battleships, equipped with 16inch rifles. She mostly took part in shore bombardment, supporting landings at Tarawa, Kwajalein, Eniwetok and the Marianas operation between 1943 and 1944 in the Pacific. On 24 July 1944, while bombarding Tinian, she was hit by shore batteries, causing serious casualties among exposed crew topside. She was also hit by kamakazi planes in the late-war era of her service.
USS Mexico is known to be the ship that carried Woodrow Wilson, then president of the US, to France in order sign the Treaty of Versailles. In WW2, she, like many USN battleships, was used for shore bombardment.
KMS Graf Spee - pocket battleship, armed with battleship-like 11 inch (283mm) cannons and battleship style secondary batteries in a cruiser hull with cruiser specifications. She was primarily tasked with raiding convoys of merchant ships. She was credited with sinking 8 merchant ships and disrupting their convoys. She was engaged by HMS Exeter, HMS Ajax, and HMS Achilles in one of the first naval engagements of WW2. After being damaged significantly she escape to a neutral port and a tilled after misinformed that the three British ships were waiting for her outside the harbor. Closer inspection by the British with approval by the neutral port revealed she had radar.
