The political case for F3 could emphasize Treasury savings and fleet-wide ammunition compatibility. Frederick Field's strategic ability is judged stronger here than his handling of ministers, leaving that financial case without the advocacy Henderson or Jellicoe might have supplied. The proposed 15-inch/50 used the existing 15-inch shell and breech mechanism, reducing logistical and development risk. Limited testing suggested greater range, while rearming Hood, Renown, Repulse, the Queen Elizabeths, and the Revenge class could extend their useful lives. Delaying replacement would give the Treasury a reason to support the gun beyond the cost of the two new ships.
