Abercrombie, Lord Clive, Marshal Soult and Gorgon class monitors

The four monitors of the Abercrombie class were built to take advantage of four twin 14in turrets, offered to Great Britain by Charles M. Schwab, president of the American company Bethlehem Steel.
The eight monitors of the Lord Clive class were virtual repeats of the Abercrombie class monitors, but armed with British 12in guns instead of the 14in American guns used on the earlier ships.
The two Marshal Soult class ships were probably the least successful monitors built for the British navy during the First World War.
The two Gorgon class monitors had been built as coastal battleships for the Norwegian navy, but in 1914 they were taken over by the Royal Navy.
