Talk:15.2cm Triple Gun Mount/@comment-77.132.170.173-20170814084515

At first i thought the lower FP compared to the Italians or Japanese ones represented the jamming problems those guns had because of their too complex hoist and loading system, but i found with surprise that actually they all had around the same effective ROF (5/6 rpm).

So i guess it's due to the AP shell velocity then (Fr = 840-870m/s ; It = 910m/s ; Jp = 920m/s). But even with that in mind, both the French and Japanese guns still had a longer range, heavier shells, bigger bursting charges and better armor penetration than the Italian ones. So i don't understand the bigger FP of the OTO...

Also i don't understand the lower AA stat. The French 152mm on the Richelieu were specifically  build  DP mountings and had a max elevation angle of 75° (90° planned, 85° postwar). Even though in the end they were an utter failure in the AA role, the Japanese or Italian guns fitted on their battleships were just SP mountings and had lower elevation... So i really dont understand why they, the SP guns, had bigger AA and the DP gun had the lowest...
