A machineguns caliber is to low since it's unlikely to land many hits so I wanted something a bit higher caliber.
But quad is fine, just ramp it up a bit to use bigger rounds so even a few hits will do massive damage.

[tryrar]

.....what the hell does caliber have to do with chance to hit? It has more to do with the gunsight and the rate of fire than caliber

[Brood]

Read what I just said again.

I said it's got a low caliber and since it's chance to hit is also low a higher caliber is better because 3 small bullets does less damage then 3 big bullets.
So rapid fire and high caliber is better then rapid fire and lower caliber.

BIGGER, BIGGER, BIGGER, LOL.

14.5mm is a huge caliber for that purposes and you want even bigger? We may do 20mm or 23mm but that means heavier weight, lower rate of fire, fewer ammo and wasted time researching new weapon when we can use existing machinegun

Bigger doesn't equals better. I am tired to repeat that

[tryrar]

Again, caliber doesn't necessarily dictate damage. It also depends on velocity and what the round is made up of to determine penetration and damage. A large, low velocity round doesn't always do more damage than a small, high velocity round.

For instance, the reason the German 88mm was such an awesome AT gun was that it spit out its rounds at over 2500 feet per second(or 820m/s), imparting enough force on impact to penetrate any armor it faced at up to a kilometer. Now, I'm not saying a larger round wouldn't do more damage, but you'll need an exponentially more amound of powder to propel a larger round at similar force as an equivilant smaller caliber.

Edit:To illustrate UR's point, 14.5mm is .57 caliber, bigger than the M2 Browning!

Whatever I give up, your so fixated on you can't possibly be wrong and everything should be your way trying to make a suggestion is pointless.
I wanted a bigger round because of the kind of round I was thinking of for it, in which a larger bullet would be beneficial.

[tryrar]

Dude, we're trying to rationally explain why going bigger isn't always a good idea, no need to get huffy

[Brood]

Or you could let me do it first, wait for the results of the test then decide if it was right or not, rather then deciding it's bad without even having any of the details I intended to for the weapon.

...ok then, let's see your weapon. We can be rational about it if we see what you've designed

[Doomblade187]

I was thinking general use. It should be good at both AA AND at anti-ship. Now that we have some good weapons for both roles, we should not have much of an issue.

How about this?

Hero-class Cruiser(Герой крейсер)
Engineers:8+metallurgist&naval engineer
Workspace:10

Armor:3'(76mm) plating below waterline, 2^1/2'(64mm) above waterline
Armament:2x twin 280mm turrets, 6x LUP-40 AA/AS turrets, 10x siderail-mounted TP-1s, 8 foward torpedo tubes, 2 aft torpedo tubes

Problem is mesor, we don't have any air units attacking us(AFAIK), so your design in superfluous until we do. Plus, having a dedicated AA is just asking for trouble if you run into a heavy surface fleet, it should have at least ONE gun for defending itself

I second this design for a cruiser. Perhaps we should see how well the 280mm gun works against ships first, though?

Name: F.A.A.W ( Fragmenting anti aircraft weapon. )
Number Of Engineers: 5
Workspace: 5
What It Is.
4 fixed barrels firing a high velocity 17 mm fragmenting round with a 360 degree field of fire and elevation of -10 to 100 with a max range of 75 meters.

The reason for the larger bullet is it's fragmenting and without exception a larger fragmenting round is more effective, the larger the bullet the more parts it can break up into on impact and with this kind of a bullet a single round hitting a plane will do catastrophic internal damage.
No solid bullet will do more damage then this bullet and a larger bullet is always better for this kind of task if you want maximum stopping power.
4 barrels because the size does slow it's fire rate so by using 4 barrels rather then 1 it counters the lower rate of fire by firing in sequence.

The main reason for this? We tested this kind of thing a couple years back going upto a 50 mm bullet and without fail the largest round did the most damage because it had the biggest fragmentation pattern.
Want to stop a plane quickly? Put a huge fragmenting round through it, if it doesn't blow it up clear it's going to do so much internal damage it'll drop out of the sky anyway.

You'll want a bigger max range- 75 meters is only around, say, 200 feet, a little more than that.

[Brood]

It's intended for close range only anyway but true, I couldn't decide on range so just used 75 as a baseline. The main point for the weapon is the fragmenting round and multi barrels to counter the rate of fire.

In fact I based TP-1's caliber on that baby : http://en.wikipedia.org/wiki/KPV_heavy_machine_gun

Note that not only it has larger caliber than M2 browning, but it has longer bullet 14.5mm*117mm is much nastier than 12.7*99mm.

Also, note that standard German WW2 automatic AA guns had 20mm*82mm bullets.

Hispana-Suiza had 20mm*114mm,  we may design it's analog later, in late 30th, when it was created IRL

Gm will be sad with all that flood  again

with a max range of 75 meters.

Just lol, I can't take you seriously after that. You want an oversized shotgun? Or  what?
And what the hell is fragmenting round?

A fragmenting round is like a frag grenade bullet.
