Hey, no channel has been made for naval guns so I post my question here: do we have any proof that the H/PJ-45 130mm gun has a rate of fire of 40-45 rds/min? ...
first, provide a link to your claim (so that other members can see what body part was used to pull or push your number) -- my google search didn't show a rate of fire of that Chinese 130 mm, and I won't be surprised if it's classified, actually I'd be surprised if the PLAN announced this info
second, had your number been correct, it would've referred to a cyclic rate of fire, I think
(in short, an EXTRAPOLATION to one minute, for example the Bofors 57 mm has "cyclic rate" of more than 200 (two-hundred), but just 40 (forty) rounds hoisted LOL
so that 130 mm would be able to discharge FOR INSTANCE 10 (ten) rounds during the first fifteen (15) seconds meaning a cyclic rate of 40 rounds per minute I said FOR INSTANCE in this line so don't nitpick)
