John Roberts's published work on British battlecruisers and Tiger provides a starting map for finding the underlying constructor and Admiralty files. The route into those files began with interwar aircraft-carrier research because the Royal Navy drew hull metrics and design ideas from battlecruiser experience during the 1920s and 1930s. Following Roberts's references into the archives connected particular documents with later carrier studies. This is a compact example of historical method and shows why Tiger's machinery and hull form matter beyond debates about battlecruiser armor thickness.

How carrier-hull research led back to Tiger's machinery
John Roberts's battlecruiser studies provide a route into the archival hull and machinery evidence that also informed Royal Navy carrier development.
