HMS Iron Duke
The Iron Duke class of ships had the 13.5 inch main and to combat the increased range of the 21 inch torpedo, had 12 × 6 inch secondary guns to engage torpedo boats at a greater range. The ships were slightly longer and had a greater beam and depth than the King George V ships, to overcome the heavier armament. All were fitted with a tripod forward mast to house the fire director control station, which was a shortcoming off the preceding ships. They were the first class of battleships to have anti-aircraft guns fitted as part of the design, with two 12 pounder guns mounted on the aft superstructure, intended to be used against airships. The ships also did away with the stern torpedo tube, having provision for only one 21 inch tube on each side. The Marlborough became the only dreadnought-type ship to be torpedoed at Jutland and had a 70 feet (21 m) by 20 feet (6.1 m) hole blown in her side. After the Great War they were all apart from Iron Duke scrapped to comply with the Washington Naval Treaty. The Iron Duke became a gunnery training ship in 1931.
Revenge class
HMS Revenge, HMS Royal Sovereign, HMS Royal Oak, HMS Resolution, HMS Ramilles.
The Revenge class (or as sometimes known, the Royal Sovereign class) were designed as a cheaper alternative to the Queen Elizabeth class. Plans had initially been for a class of eight ships, but at the start of the Great War work stopped on all new capital ships. The last three ships Renown, Repulse and Resistance were cancelled. The first two of these were eventually redesigned as battlecruisers. During design they were planned to have a maximum speed of just over 21 knots and had reverted to being coal- and oil-fuelled. However in 1915, this was changed and they became oil-fuelled only. Secondary armament was fourteen 6 inch, two 3 inch anti-aircraft, four 3 pounder guns and four 21 inch torpedoes. Both Revenge and Royal Oak were completed in time to take part in the battle of Jutland.
Queen Elizabeth class
HMS Queen Elizabeth, HMS Warspite, HMS Barham, HMS Valiant, HMS Malaya.
The Queen Elizabeth class had its main armament of eight 15 inch guns arranged in four double turrets. The new calibre guns were intended to still give the Royal Navy and an advantage in range over newer American and Japanese ships which the Admiralty expected were to be armed with 14 inch guns. The initial design was for a five turret ship, being reduced to four when it was realised its greater range and hitting power with a broadside of 15,000 pounds (6,800 kg) compared to 14,000 pounds (6,400 kg) in the Iron Duke class. Secondary armament was fourteen 6 inch, two 3 inch anti-aircraft and four 21 inch torpedoes. The space saved by the reduction of one turret was used to house additional boilers which gave the ships a speed of 24–25 knots.[
HMS Nelson, HMS Rodney
The two ships of the Nelson class were the only new battleships the Royal Navy were allowed to build under the terms of the Washington Naval Treaty. The layout was based on that of the N3 battleship and G3 battlecruiser but further reduced to come under the weight limit. Nine BL 16 inch Mk I guns – the same as were to have been used on the G3 battlecruisers – were carried in three forward turrets. Secondary armament was twelve 6-inch guns mounted in six turrets at the rear of the ship, six 4.7-inch anti-aircraft guns, seven eight-barrelled 2-pounder "pompom" mountings, four quadruple 40 mm Bofors guns and sixty five 20 mm Oerlikon cannon.
