A 1929 report treats exercise results as insufficient to settle the relative value of battlecruisers and fast battleships. The document calls for both strategic and tactical experiments rather than judging the ships only inside a fleet action. It then cites a projected 10,000-ton German ship with long range and 11-inch guns as a threat other navies might imitate without the same tonnage limit. The concern was economic warfare: Britain might need a ship able to catch and overpower such raiders without diverting its whole battle fleet.

The 1929 exercises kept the battlecruiser question open
A 1929 exercise report called for more strategic and tactical testing because new long-range German armored ships could renew the need for battlecruisers.
