British 15-inch Gun Turrets
Changes to the construction programme as a result of the outbreak of World War One led to the reallocation of many of the 15-inch turrets ordered for the last of the RN 'R' class battleships in 1913-15. There were a further series of reallocations during World War Two to accommodate the Monitor programme and the construction of HMS Vanguard.
The following table has been compiled from a number of secondary sources, some of which conflict, but is believed to be correct based on the information available.
