The Second World War accelerated a long imperial transition, while rapid decolonisation left coercive institutions stronger than democratic counterweights in some new states.
Queen Elizabeth's strike-carrier layout and sortie-generation system matter more than simply comparing her air group with the combined aircraft on two American LHDs.
Graf Zeppelin ranks worst as a carrier design, while Shinano's loss reflects unfinished systems and crew familiarity as much as the underlying concept.
The preserved HMAS Vampire offers a surviving route to inspect machinery broadly comparable to that fitted in the Royal Navy's Daring-class destroyers.
Late-1950s cruisers with twin automatic six-inch turrets could survive the Falklands and Gulf wars because shore bombardment gives them a role no other British ship could match.
Completing a third Renown would not cancel the Admiral class, but it could redirect modernization money and alter the forces sent against Bismarck or to East Asia.
Uneven Rapier performance in the Falklands drove a more effective mobile system, while the fighting also showed the value of dense 40 mm defense at San Carlos.
A Britain that retained major-fleet status could play a more active East Asian naval role, but operations would still depend on each government's willingness to fund and use the force.
Four Canadian Iroquois-class destroyers would deepen the task force's air-defense screen, with most remaining at sea rather than entering San Carlos Water.
Keeping Vanguard as a usable reserve ship would require sheltered berthing, continuous maintenance, refits, trained reservists, and annual activation trials.
Losing one or both British carriers would not necessarily end the Falklands campaign because Britain had other hulls and the United States had discussed making a carrier available.
Weight savings alone would not make Nelson fast, but a new 1930s derivative with three shafts, modern boilers, and stronger turbines could exceed 28 knots.
In this 2022 comparison, Australia's LHDs and prospective nuclear submarines place the RAN slightly ahead of the RCN, even with Type 26-derived frigates in view.
Common 16-inch ammunition with the Iowa class would be useful, but Vanguard could retain her existing 15-inch battery if modernization funds were scarce.
The Greek fleet is recast as a sea-denial force using American-built submarines and mines to protect eastern supply routes and constrain Italian logistics.
Australia and Canada can grow into significant minor naval powers during the war, while conquered small navies have little time to correct their weaknesses.
Finland illustrates how national strength can rest on institutions and resolve even when geography leaves a small state exposed to larger authoritarian neighbors.
A Nordic neutrality pact with combined command could have given Finland maritime access and made aggression against any one Scandinavian state more costly.
Norway's government failed to issue alerts and mobilization orders after Germany invaded Denmark, leaving the country unprepared for the German attack.
The opening defines a hard reform test: identify weaknesses that Japan, Italy, and Germany could still address with the war already under way or approaching.
