Talk:5inch Single Gun Mount Mk.30/@comment-175.156.13.185-20180422161421/@comment-33100091-20180430085728

While VT would in part explain it's performance in AA capacity...

it did not explain why the gun spanked ships in Samar including heavy cruisers which normally were designed to have enough armor to be close to immune to penetration from 5inch shells.

Rather than VT (which wouldn't exactly do anything against warships) it was more the gun's exceptional accuracy thanks to the fire control system and good rate of fire (a good number of the USN DD and DE in Samar expended their entire ammunition capacity for the 5 inch guns in that single fight before sunk or withdrawing) that seems to have helped the DD and DE.
