Well, if i can highjack this thread on a not serious way...

Just for fun, the french MEDIA ( here, the important and funny word is MEDIA [;)] )
usually know nothing about it.
Look at a video in irak/afghanistan/africa/elsewhere with fightings.
The mortar are called "heavy artillery" [8|]
The light machines-guns are called "light-cannon" [8|]
The rocket-launcher are called bazooka or missiles" [8|]
i even heard some howitzer called "heavy-anti-tank-cannon" [8|][8|][8|]

i think the reporters should have done their time of Military service, this would avoid those stupid comments [;)]

It's not just French "journalist". Do you recall a couple of years ago the AP reporter who held a handfull of unfired rounds and said that they had been fired at a woman's house? [X(][8|][:(]

Indeed, keep it on topic guys, I need an answer. Just can't get no sleep at night over it!
Not our style! We reserve the right to take any thread and turn it into one of the claasics:
Classics include but are not limited to:

What if the Japanese had won Midway
What if the Allies knew the attack was coming at Pearl Harbor
Which is the Best Battle ship: Bismark, Iowa or Yamato
Was the drive through the central pacific worth it or was McArther right all along

I am sure there are 20 classic threads missing, please feel free to chip in

Ok to answer to OPs question so he can sleep soundly at night the rule for airplanes is if it's .50 cal or under and doesn't fire an explosive shell it's a machine gun. 16mm or over and fires an explosive shell it's a cannon. The one exception is the German 15mm which is for now classified as a hybrid-until it can be determined if fired solid shot or explosive shells or both.

Land gets more complicated. You have inches, milimeters and pounds. One poster mentioned carriage mounting was a determining factor. Then there is the question of the period when cannons were referred to by names, not by the diameter or weight of projectile. Urbans bombard used in the siege of Constantinople or the US Civil War when cannons were referred to by names like Napoleon or Parrots. In more modern times referring to cannons by name is more arbitary. You has the M1 and M2 155mm referred to as "The Long Tom" while other 155mm models were not referred to by a common accepted name. Today that arbitary naming persists.

The Navy seems to prefer inches with some exception-I see some British ships with guns using the "pound" convention. It was also mentioned that "naval rifles" was also once commonly used.

Based on land usage, my opinion is:
A gun is a direct fire weapon. Aimed directly at the target, or leading the target.
A howitzer is an indirect fire weapon normally fired based on maths about where the "shells" are to land. Mortars are a type of howitzer having a higher trajectory.

Taking in the air-to-air and air-to-ground arena, I used to work on RAF Phantoms. They carried the SUU-23A GUN. In training it fired 20mm solid rounds but used explosive rounds in real combat. Based on previous discussions does that make it both a gun and a cannon?

But for naval guns - given the earlier land based definitions, at short range under local control they could be guns. But at longer range, and particularly under director control, they could be howitzers.

A further complication is that cannon could be a term used for smooth bore weapons, whereas almost everything discussed (except mortars) is rifled.

I think it is all semantics with no right or wrong answer.

jmscho - I think part of the definition is that howitzers can fire both direct and indirect. Mortars can only fire indirect, guns direct. Or should I say 'are designed to' instead of 'can only'?

witpqs. I did say "normally". But you're right, most weapons with sights can be used in a direct fire mode. Although mortars even break that rule because they have sights but are more an indirect fire weapon. As I said originally, it's semantics. There will always be exceptions that break the rule.

Well, now you all have it figured out, let me throw this dead skunk on the fire. "Every" term depends on "usage". There are some few hard technical definitions, but they are far and few between - and depend on the nation that's defining them.

In the US Army Artillery Branch (ca. 1970) you had cannons, howitzers, guns. Cannons was a generic term for a tube. That's why people called us cannon-cockers. Howitzer is probably the most technical term - low chamber/barrel pressure, high angle mount, and "therefore" you can shoot some really nasty ammo designed to 'fit'. Gun is maybe next in technical terms (but not for fun). Gun is maybe 1/3 longer in calibers, and also has a high angle mount. An Arty gun is not DF. It has a higher chamber/barrel pressure and is designed for range. A 155mm Gun shoots different stuff from a 1m5mm Howitzer.

But nobody cared what they were called. They were guns, cannons, tubes, whatever. There was no technical distinction; it was a howitzer, a gun-howitzer, a gun, and who gave a poopie. Everybody knew, from the name, what it was and what it could do. It was a spectrum and the "name" was meaningless.

Can´t it be that 80% of all these explanations are the the reason why the terms are now stuck at about the current definitions?

Worth noting that the M61 (I think) Vulcan carried by a lot of modern USAAF fighter aircraft (like the F15 Eagle) has just about the highest rate of fire of any air-to-air or air-to-groudn weapon (thanks to its six barrels) yet is still regarded as a cannon. And also the dreaded 37mm Gau-gun carried on teh A10 also has an even more fantastic rate of fire (sounds like a super-charged buzz-saw going) yet is also considered a cannon.
So it's also not just down to rate-of-fire...

So where does the water cannon fit in? Is there a water howitzer? I think I have heard of a water gun before. [8D]

Well a MG does have a faster rate of fire. MG typically 1000+ rounds per minute. A cannon will be around 60-100 rpms.

Also, the cannon will typically have a higher powder charge for its projectile, thus increasing range and hitting point. Bigger gun, bigger shell, more power, slower rate of fire for cannon.

Water cannon is in a catagory of it's own. Don't know how that is classified or if they use inches, milimeters or the pounds ejected per second standard.

It has to be included. The Egyptians used water cannons to hose down and cut openings for tanks in the sand embankments at the Bar Lev line in 1973 so they do have a place in the catagory.
