Corbett, Mahan, and what sea control is for

Is the battlecruiser debate essentially Corbettian strategy versus Mahanian strategy?

Partly: Mahan explains gaining command through battle, while Corbett helps explain the wider purposes for which sea control is used.

Mahan's emphasis on concentrated battle helps explain how a navy might win command of the sea. The decisive engagement, however, accounts for only half of naval war. Corbett's approach asks what command is then used for, including communications, trade, military movement, and political pressure. The battlecruiser debate reflects that wider question because a globally committed navy needed ships for the uses of sea control as well as for obtaining it in battle.
