In May 1920 the Royal Navy commissioned one of the most impressive ships in its history, the HMS Hood battlecruiser. For the next 20 years, this ship would be the largest in the world and the pride of the British fleet. She can be considered as the maximum exponent of this type of ships, but at the same time, she also showed the most obvious shortcomings. Despite having projected 4 units of thiis class, finally only HMS Hood was finished, due to the disaster suffered by the British battlecruisers in the Battle of Jutland and which marked the end of the construction of this type of ships within the Royal Navy. Although the idea of ​​having ships armed with the guns of the battleships, the speed of the cruisers and an intermediate protection, seemed to be the best possible, in practice it was shown that they could not face ships armed with guns of the same caliber and greater protection without suffering the consequences. The “Mighty Hood” did not have a brilliant career like many of the most famous ships and she was sunk in the first serious combat she had to face.
