Scharnhorst's guns in an unrestricted battleship race

Would the eleven-inch Scharnhorst-class ships remain adequate if the major European battleship programs were completed?

They would probably receive fifteen-inch guns, while an unrestricted building race could also produce British successors to the Lion class.

An unrestricted building scenario would probably lead to the Scharnhorst-class ships receiving fifteen-inch guns. Their original armament is treated as a compromise that Germany could complete on time. The wider scenario also has to allow other navies to continue developing their fleets. Britain's five King George V-class ships, six Lions, and perhaps two or four Vanguards would not necessarily end its construction program. If Germany built H39-type ships after treaty limits collapsed, a British successor to the Lion class could follow.
