I am disappointed. There is no mention of the fact that Thunderer was the first British Battleship to be constructed with a Central Fire-Control Director, while all ships built prior to her were retrofitted with the director.
He mixed up the reference. I remember seeing that information in Monarch instead

Thunderer is the fourth of the Orion class battleships.
She take part in the Battle of Jutland as member of the 2nd Battle Squad and engaged with German cruiser Lutzow along with her sisters.
In according to the Washington Naval Treaty, Royal Navy desiced to take out Thunderer and King George V in exchange of two newly built Nelson class battleships. Until Nelson entered service, Thunderer is kept as training ship.
She's sold after being delisted in December 1926 and scrapped in 1927.
