One of my ships, the USS Gray (namesake of SGT Ross Franklin Gray, USMCR; a WWII hero), was attacked by two Russian fighters off the coast of Viet Nam during that conflict. She put up such a devastating wall of fire with her 5" gun, that one of the attacking aircraft (piloted by NV regulars) crashed on his inbound run attempting to avoid the fire...and the other peeled off and returned to base.
While taking on ammo at Seal Beach, after the fire and safety parties were manned up one weekend (most of the ship's crew on liberty), there were only TWO of us to move 300 rounds (oddly 42 pounds each, like the charges pictured at Libertas' linky...but a different kind of gun. Not the same charges.) Me and SK1 Flowers, spent a very loooong time moving ammo that day.
Spent some time on the gun line out at San Clemente with the New Jersey after she was recommissioned in the early 1980s. Our gun would cause the Gray to jump over about an inch when she was fired~in spite of the big sonar dome directly under her. I cannot imagine what it felt like on those battleships throwing Volkswagens at goats on the island out there, but the gout of flame (even in daytime) was awesome. (First time they test fired after recommissioning, they were stunned at how much PAINT simply flaked off the deck structures...they kept her out for three days to repaint in order to deny the Soviets intel on the effect of the guns.)
When we would go out to San Clemente for gunnery practice, the Marine range officer would let us fire a few rounds for warmup with his Marines, then he would come out and ask us to miss on purpose so he could train his Marines how to give corrections to us.
