The QF 4.5in Mk V is a naval gun of British origin. It served during the second Weltkrieg and was eagerly adopted in Oceanyka as a modern, capable weapon. The design is so rigid, simple and effective that little to no modifications have been made to the gun itself. The turrets or casemates may be adjusted to a personal preference basis. Despite not being labeled a "Multipurpose Gun", the 4.5in was designed with anti air capabilities in mind and can fire timed or proximity fuzed shells to take down aircraft.
