Depends what those 500 rounds were fired from. A gattling gun that’s about two seconds.
Where about in Oregon ya from?
Yup, and the Russians typically fit their ships with lots and lots of auxiliary armament. Their Kirov-class battlecruisers (yes, I said battlecruisers) mount as auxiliaries 8 each AK-630 30mm gatling cannon (part of their CIWS equivalent) and the secondary armament (after the primary arm of missiles) is a twin mount 100 or 130mm dual purpose cannon capable of firing between 10 and 40 rounds per minute per gun all by itself with no loading crew. Their destroyers are even more gun-heavy - the Sovremenny class, their main surface combatants, have TWO twin mount 130mm DP cannon, and four of the AK-630 gatling cannon.
The Russians seem to love bolting guns onto their naval vessels for some reason.
