Vice-Admiral Sir George John Scott Warrender, 7th Baronet, was a Royal Navy officer during World War I.

HMS Barfleur was the second and last of the Centurion-class pre-dreadnought battleships built for the Royal Navy in the 1890s. Intended for service abroad, they exchanged heavy armour and a powerful armament for high speed and long range to counter the foreign armoured cruisers then being built as commerce raiders and were rated as second-class battleships.
