Did the Italians have a dual-purpose naval gun?
Short answerYes; the 100 mm and 120 mm families were the Regia Marina's most prominent dual-purpose weapons.
NotesThe 100 mm and 120 mm families were the Regia Marina's main dual-purpose answers. Battleships and destroyers leaned on the 120 mm caliber, while smaller ships could use 100 mm weapons. Dual-purpose capability was distributed differently across ship types rather than supplied by one universal mount. Together these families provide a concise map of Italian secondary and anti-aircraft gun choices.
