Hood's usefulness had deteriorated because of advances in naval gunnery. She was scheduled to undergo a major rebuild in 1941 to correct these issues, but the outbreak of World War II forced the ship into service without the upgrades.
In May 1941, she and the battleship HMS Prince of Wales were ordered to intercept the German battleship Bismarck which was en route to attack convoys in the Atlantic. On 24 May 1941, Hood was struck by several German shells early in the Battle of the Denmark Strait and exploded; the loss had a profound effect on the British. Prime Minister Winston Churchill ordered the Royal Navy to "sink the Bismarck", and they fulfilled his command on 26–27 May.
Of the 1,418 crew, only three men survived. They were rescued about two hours after the sinking by the destroyer HMS Electra.
I don't know how to transfer a link, but copy the URL below, and see what an English modeler did with his kit of Hood, and Bismarck as well!
It has been recorded as the shortest dual between capital-class dreadnaughts(battleships) in world-naval history.
The fifth salvo from the Bismarck hit the ship's magazine for X Turret resulting in a catastrophic explosion below the main mast, which tore it in half, and it sank in less than three minutes.
Bismark was a Battleship, Hood was an upgraded Battlecruiser, she did not have the sufficient deck armour on the aft half to counter plunging rounds.
