Title: Request for aircraft cannon


Forza - May 22, 2011 02:13 AM (GMT)
As many of you may have figured, I am a complete dead-shit when it comes to firearms and I know nothing about the subject. Thus, for a new fighter jet I was wondering if anybody had a predesigned cannon suited for fighters that I can pretty much bolt straight in to the aircraft.

In terms of rounds, I would prefer a 20mm gun in favour of carrying more ammunition rather than packing a huge punch, although I will accept a 25 or 30mm weapon if somebody already has one.

I would be looking to have the write up of the weapon pasted straight into the write up of the jet, but don't worry, full credit will be given.

Is this for NS or SMS?

Forza - May 22, 2011 11:44 AM (GMT)
Inevitably both.

Ekraysia - May 22, 2011 12:43 PM (GMT)
Well, I don't sell stuff for NS anymore, so I can't help you there.

Andorianus\Dystopianus - May 22, 2011 04:49 PM (GMT)
Even though I promised to stay away from NSD for a while, this something in which I'd be glad to help. My F-99 "Valkyrie" air superiority fighter project (which is now on hold) uses a Tround autocannon. The project is an old project and isn't screened by NSD yet, so it may contain some faillures as of now. But if you are interested I will make a seperate thread in order to finish the project.

-Cannon-
The F-99 comes standard with one "C-02" 27x200mm Tround autocannon located on either side of the cockpit, however, a second one can be installed if the user sees fit. This cannon is manafactured by Ballistech (headquarters located in Andorianus) and chosen for its splendid accuracy and good rate of fire. Many electronic advances are equipped to make sure all shots ultimately hit their respective targets.

Tround systems are next generation in fighter cannons. This short video shows the C-01, a technology demonstrator which provided the basics for the system we are using right now. However, the tround cannon we are using is of a rotary hibrid, meaning it has 6 barrels with 6 chambers instead of 1 barrel with 3 chambers. This means most problems occuring with revolver cannons are eliminated. To ensure a high ROF, the cannon is continuesly driven by an electrical generator and rotates all the time, instead of just when the cannon is fired. This means the cannon does not need much time to accelerate to maximum firing speed. The first bullet always leaves the barrel in at least 400th of a second, which is good as instantly.

The cannon is placed on the star side of the plane just behind the cockpit. A trim tab on the other side of the cockpit is automatically extended in just a few milliseconds as soon as the cannon is fired, in order to counteract the recoil. When two cannons are installed, the trim tab is removed from the plane entirely, and the cannons are sinchronised instead to provide even more balance and accuracy. This autocannon can fire 3500 rounds per minute from the first round, but the cannon's firepower can be increased to a staggering 6000 rounds per minute, although a rate of fire this fast will drastically decrease accuracy. Therefore, the AI determines the rate of fire automatically depending on the range to target. This function can be turned off. The cannon uses plasma ignition for propelling the bullets, providing reliable combustion of the propellent and ensuring both pinpoint accuracy and rapid fire. Further increasing the accuracy, the C-02 has an anti-recoil mechanism that channels recoil to the sides of the cannon, and also provides easy removal of spent cartriges. Finally, the cannon is linked to the fighter's computer which automatically adjusts it's position towards the target, in order to provide more accuracy. The information calculated by the computer is linked to the Valkyrie's BALCOTH interface so it can predict where the bullets will strike. Unparrelelled pinpoint precision is key with the C-02.

When enemies are not within visual range, the cannons are covered by a small "hatch" which covers the cannons and thereby, reduces RCS and improves aerodinamics.

The Valkyrie is designed to be modular, so the cannon can be replaced by Russandrian engineers with a second autocannon, or a different cannon with very few modifications. Ballistech also sells the C-02 seperatly for installation on other aircraft. Ballistech also sells the C-03 and the C-04, which is basically the same gun in 20mm and 30mm respectively. These cannons can also be installed on the F-99 on request, although when the 35mm variant is used, only 1 cannon can be fitted at the same time. For the fighter role the Dystopian military has advised the use of 27mm rounds however, due to their splendid accuracy and peformance. For more information on the C-02, C-03, and C-04 or for seperate purhchase, please send a telegram to Ballistech, Andorianus. Ballistech is currently also developing a C-05 salvo cannon, which can fire multiple shots at once. This cannon might be available on the F-99 in the near future.

The ammunition drum is provided with each cannon for no extra cost; each drum contains 1200 rounds. Less rounds can be fitted in order to save weigth.

Finally, the customer also gets the choice from a wide variety of ammunition, including but not limited to AP, APDS, APFSDS, HE, HEAP, HEfrag, HEAPfrag,  HE incindiary, HEAP incindiary, APCR, and more. However, not all of these might be suitable for the fighter application. All of these variants can be bought from our sister company, Ekeziel Inc*.

*OOC Note: Please don't include ammunition in your orders, it makes it more difficult for me to keep track of your orders. Besides, on NS everyone already gets production rights for RL designs, and the 27mm round is a RL design.

(Just screening through it; the part about anti-recoil mechanisms should be removed or elaborated. I'll do that, eventually.

Might try asking Mek/Amastol,

did someone mention trounds

I'll get to correct that, eventually. If Forza is interested, I'll correct that right away; if he isn't interested, I'll correct it as soon as I'll get back to my fighter again.

"Trounds" suck for this application. They increase gun weight and decrease MV, both things you don't want in an airborne cannon.

I'd sell you my H16 cannon designed for F1X/F2X, but it's got a 5m barrel, so your planes won't be able to fit it anyway.

wait wasn't the purpose of the tround to save weight by eliminating the need for a separate breech-sealing cycle?

Make sure it's ETC.

Sumer - May 23, 2011 02:16 PM (GMT)
All true fighters need to use 50x300mm Sumerian.

By massively increasing the required pressure vessel mass.
Or, massively increasing required case weight.

Makes sense.

That sounds pretty heavy on the recoil.

Better make it a RAVEN gun.

Forza - May 24, 2011 10:09 AM (GMT)
Well are there any other options?

It's not supposed to be a tround, mind. It will be changed in a rotary cannon.

Probably not for NS.

Crookfur - May 24, 2011 04:00 PM (GMT)
Well there is my GX-35 series but they don't exist as anything other than few lines in various aircraft write ups.

Basically its a 25x190mm CTA gun using a Gast mechanism for a lulz rof of 2500rpm (depending on model). Sometimes it gets ETI to allow it to use inssnentiive propelelant, sometiems it doesn't. It really depends on how I/the cusotmer feel(s).

if anyone was particualrly depserate to sue it I could put some work into detailing it.

That sounds good, I would be certainly interested in using it.

Bloody_Sahara - May 25, 2011 12:54 AM (GMT)
use 57*441.

it's funny because it was once an AT round.

Nah, I think I'm fine married to my abusive 35x135mm autocannon (to replace rimmed 37x140R).

*Not to be confused with Crookfur, srsly*

I could probably neck-up a .60 cal to a 20-something millimeter shell-size.

Which BTW is how USSR and USA achieved their respective 23 and 20 mm shells.

Kinda difficult explaining how my 23mm is shorter than the soviet one, so I'll just call it the 22x88mm and confuse teh nubz as I teach them to fear double-digits.

For AMR-use, I think I'll just use a bastardized 20x42 into 22x44, just to keep commonality.
