A better 15-inch gun as a fleet-wide modernization path

The discussion argues that a longer 15-inch gun could have created a common modernization route for Queen Elizabeth-class ships, the R class, Renown, Repulse, and Hood. It contrasts ballistic potential with the practical advantage of improved fire control and training for existing World War I-era weapons. Ships expected to remain in service longest would receive the new standard first, reversing some historical refit priorities. The comparison shows how a new gun programme would have competed with the costs and limits of upgrading established ships.
