The London class was a group of five predreadnought battleships built for the British Royal Navy in the late 1890s and early 1900s. The class comprised London, Bulwark, Venerable, Queen, and Prince of Wales. The ships of the London class were very similar to the preceding Formidable class, with the main differences being their armour layout. They were armed with a battery of four 12-inch (305 mm) guns and they had top speed of 18 knots. They are sometimes referred to as being part of the Formidable class due to their similarity, or as being a class of three ships, with the last two forming their own Queen class. The five ships were built between 1898 and 1904 at the Portsmouth, Devonport, and Chatham Dockyards.

HMS London was the lead ship of the London class of pre-dreadnought battleships built for the British Royal Navy. The Londons were near repeats of the preceding Formidable-class battleships, but with modified armour protection. The ship was laid down in December 1898, was launched in September 1899, and was completed in June 1902. Commissioned the same month, she served with the Mediterranean Fleet until early 1907. She was assigned to the Nore Division of the Home Fleet for nearly a year before transferring to the Channel Fleet. Rendered obsolete with the emergence of the new dreadnoughts in late 1906, she underwent an extensive refit in 1909, after which she served with the Atlantic Fleet. She was assigned to the Second Home Fleet in 1912 as part of the 5th Battle Squadron, and was temporarily fitted with a makeshift ramp for experiments with naval aircraft until 1913.
