In January 1915 the Admiralty decided to build two 381mm-gunncd monitors, in addition to the 305mm already authorised. Although the hull had to be enlarged to accommodate the much heavier 381mm mounting, draught was still to be no more than 3.0m and beam was held at 27.5m to enable them to be docked easily. The most severe technical problem encountered was the need to find room in a shallow hull for the ammunition trunk. As a result the barbette projected 5.2m above the deck, giving the ships a much more impressive profile than the earlier monitors. Fisher wanted them to have diesel engines and so the engines of the fleet oilers Trefoil and Turmoil were commandeered. Unfortunately the mistakes in the previous classes were repeated; the installed power was too low for such a full-bodied hull form, and they were grossly underpowered for the displacement and almost impossible to steer. It had been hoped to use the turrets building for Renown and Repulse (the fourth turret for the original design) but they could not be ready before 1916. In their place turrets were diverted from Ramillies, allowing the ships to be completed by November 1915 at the latest. The provisional numbers M13 and M14 were allocated but names of Napoleonic marshals were chosen as a compliment to France. The trials of Marshal Ney were disastrous as her MAN diesels were very difficult to start. Even when she was persuaded to start her speed was only 6kts instead of the 9kts expected. The results of machinery trials were so disheartening that the Admiralty seriously considered stopping work on both ships and transferring the turrets to other ships, but the trials of Marshal Soult were better and they were reprieved. Another scheme to arm them with the turrets from the battleship Illustrious or her sister Caesar was rejected. When completed both ships had diminutive funnels, which coupled with the tall tripod and massive turret gave them a bizarre look.
Machinery and magazine were protected by 102mm internal sloped belt, 102mm bulkheads and 102-25mm deck. Turret had 330mm face, 279mm sides and rear and 127mm roof.
