Did the Royal Navy consider adopting US-style high-pressure boiler plants?
Short answerYes, but war forced navies to freeze and implement technologies already in development rather than continue a leisurely adoption process.
NotesWar often accelerates deployment more than underlying invention. States that began preparations earlier sometimes locked in an earlier technical generation, while later entrants could select more mature systems. The Royal Navy had considered higher-pressure machinery, but wartime urgency favored systems already ready for mass construction. Mobilization dates can therefore shape an entire fleet's engineering standard.
