Would a major Tillman program cause Britain to cancel its battlecruisers?
Short answerPossibly; the Admirals might be cancelled or converted while Britain accelerates alphabet-series fast battleships and expands its dockyards.
NotesThe Admiral class might be cancelled or converted to carriers while Britain rapidly orders later fast-battleship concepts. Existing dock and yard limits would no longer be treated as fixed constraints. Enlarging facilities would turn the American program into an infrastructure race as well as a ship-design contest. The government would probably accept new spending and slower debt repayment rather than concede naval superiority.
