The M29 class comprised five monitors of the Royal Navy, all built and launched during 1915.
HMS Victorious was one of nine Majestic-class pre-dreadnought battleships of the British Royal Navy. She was armed with a main battery of four 12-inch (305 mm) guns in two twin turrets, and was capable of a top speed of 16 knots. She served primarily on home waters, and participated in the Fleet Review for the Diamond Jubilee for Queen Victoria in 1897. She served briefly in the Mediterranean in 1898 before being transferred to the China Station later that year; Victorious remained in East Asian waters until 1900, when she returned to the Mediterranean.
HMS Albemarle was a pre-dreadnought Duncan-class battleship of the Royal Navy, named after George Monck, 1st Duke of Albemarle. Built to counter a group of fast Russian battleships, Albemarle and her sister ships were capable of steaming at 19 knots, making them the fastest battleships in the world. The Duncan-class battleships were armed with a main battery of four 12-inch (305 mm) guns and they were broadly similar to the London-class battleships, though of a slightly reduced displacement and thinner armour layout. As such, they reflected a development of the lighter second-class ships of the Canopus-class battleship. Albemarle was built between her keel laying in January 1900 and her completion in November 1903.
HMS Queen was a member 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. Due to slight differences between Queen and HMS Prince of Wales and the other Londons, they are sometimes referred to as the Queen class. The ship's main battery consisted of four 12-inch (305-mm) guns, and she had top speed of 18 knots. The ship was laid down in March 1901, was launched in March 1902, and was completed in March 1904. After commissioning in April 1904, she served with the Mediterranean Fleet until 1906, when she returned to Britain before embarking on another stint with the Mediterranean Fleet later that year. Queen was transferred back to the United Kingdom in 1908 and thereafter served in the Atlantic Fleet, the Home Fleet, and finally the 5th Battle Squadron of the Second Fleet in 1914.
HMS Marshal Soult was a Royal Navy Marshal Ney-class monitor constructed in the opening years of the First World War. Laid down as M14, she was named after the French general of the Napoleonic Wars Marshal Nicolas Jean de Dieu Soult. She served in both World Wars and was decommissioned in 1946.

The ship was then converted to a minelayer and renamed HMS Medusa in 1925. In 1941 Medusa was converted to a repair and depot ship and was renamed HMS Talbot, then renamed HMS Medway II in 1944. In 1946, the vessel was sold for scrap.
