What replaced cordite in Royal Navy battleships and battlecruisers rebuilt after the First World War?
Short answerOther, improved grades of cordite rather than a wholly different propellant; SC appeared from 1927 and flashless Cordite NF was used during the Second World War.
NotesThe Royal Navy continued to use cordite after the First World War, with improved formulations. Cordite SC entered use from 1927. Flashless Cordite NF was used during the Second World War. The change was therefore to later grades of cordite rather than a wholly different propellant.
