Reply #6: Tough to beat a water-cooled!

[one-eyed fat man]

On a technical weight isn't a factor, so for sustained rate, water-cooled is the way to go. Vickers MG platoons used to routinely fire barrages during WW1 of 100,000 rounds per gun in a night.



Here's Ma Deuce's granddaddy, the M1921 water-cooled Browning .50!



On the anti-aircraft mount the condensation can was replaced with a water chest, radiator and a pump with two hoses to the water jacket to circulate the water for even better cooling. While water-cooled guns have gone out of US service, the Russians still put it to good use. The ZSU-23-4 owes its impressive rate of fire to the fact the guns are water cooled.
