She was involved in a collision with her sister ship, Hannibal, and the resulting damage meant that much of the latter part of 1903 was spent being repaired.

She participated in bombardments of Turkish forts and supported the Allied operations at Gallipoli, including the evacuation from the peninsula late in 1915.

Her propulsion system consisted of two 3-cylinder triple-expansion steam engines powered by eight coal-fired, cylindrical fire-tube Scotch marine boilers.

[2] Prince George was armed with a main battery of four BL 12-inch (305 mm) Mk VIII guns in twin-gun turrets, one forward and one aft.

This allowed Prince George and her sisters to have a deeper and lighter belt than previous battleships without any loss in protection.

[1] The barbettes for the main battery were protected with 14 in (356 mm) of armour, and the conning tower had the same thickness of steel on the sides.

Prince George was in danger of sinking for several hours, but managed to make it to Ferrol, steering with her engines and with her sternwalk awash.

[3] Prince George ended her Channel Fleet service in July 1904, and began a refit at Portsmouth.

On 17 July 1905, Prince George was transferred to the new Channel Fleet, ending this service on 4 March 1907 when she was paid off at Portsmouth.

[7] Prince George was recommissioned on 5 March 1907 to serve as the flagship of the Commander-in-Chief, Portsmouth Division of the new Home Fleet which had been organised in January 1907.

On 5 December 1907 she collided with the armoured cruiser Shannon at Portsmouth, sustaining significant damage to her deck plating and boat davits.

Prince George left the Mediterranean at the end of February and paid off at Chatham Dockyard in March to provide crews for antisubmarine vessels.

She reverted to the name Prince George in February 1919,[9] and in March transferred to Sheerness to serve as depot ship to destroyers based on the Medway.

[8] Prince George was placed on the disposal list at Sheerness on 21 February 1920, and was sold for scrapping to a British firm on 22 September 1921.
