Stern Mark XXII turrets on HMS Sheffield IWM A 4401
Stern Mark XXII turrets on classmate HMS Sheffield after she had sunk the German tanker Friederich Breme in the North Atlantic on 12 June 1941. The cylinders are empty propellant canisters. As noted by Navweaps, Tony DiGiulian describes the 6″/50 Mark XXIII as, “A reliable weapon, although somewhat obsolescent in its use of bag ammunition, manual ramming and manually-operated breech mechanism.” IWM photograph A 4401.
