Why does the weapons industry no longer make water-cooled machine guns? They're better than the aircooled ones?

1. Water weighs about 7.5 pounds per gallon. That's as much as a loaded M-16 series rifle. And space that is used to transport water is space that can't be used to carry food or ammo. Our transport capacity is large, but finite. 2. Warfare rarely involves fighting from fixed positions. Your grasp of combat is about 100 years behind the times. EDIT: To Lance- I stand corrected. Thanks for the update.

TRY THE MILITARY SECTION, JUNJIOR.

While a battle lasts more than a minute, seldom would there be a need for continuous fire for more than 1 minute.

Compare the weight of the weapons them selves, that water cooled gun is gonna weight more and require more people to serve it, than the air cooled one.

simply because they dont need to anymore. there are not many things we cant mass produce, and barrels are no exception. barrels can be changed out before you can blink if they have been destroyed by heat. also advancement in technology means that this rarley happens

1.advances in metal means barrels dissipate heat faster 2. barrel change is easy 3.water is heavy 4.sustained fire is highly inaccurate 5. steel heat and water don't mix well actually they do end result rust 6.1000 rds weapon extra barrel lighter than 1000 rounds weapon water cooling system

3 answers. 1. 20mm Vulcan 2. 30mm Defender 3. C-130H Specter Gun Ship Need I say more? Addition to the above: Accuracy by volume.

A gallon of water weighs 8.34 pounds, not 7.5

because in extreme cold temps, water freezes..
