20mm for OV-10s?

[charlielima 328]

 

The Black Ponies expended 75,616 Rounds Of 20 mike mike Ammunition in 1970. I assume it was with one of these. I have no clue how many barrels, gatling or not it has. Any help here?

Thanks Gruppe, CL

Its the MK 4 gunpod that carried 750 rounds of ammo,

Looks like the 4 barrell kind.

Mk 4 pods carried a single-barreled MK 11 cannon. The MK 11 was similar (and probably a derivative of), the 20 mm guns carried by the F-8 Crusader.

Thanks Ed, had a terrible time trying to find if it was a single barrell or not.

[Fubar512 1,350]

It sure looks like a quad barrel in that image....but wikipedia states: Mk 4 Mod 0

Developed by the US Navy, this pod is fitted with the Mk 11 Mod 5 20 mm cannon, along with 750 rounds of ammunition.[20] This pod is said to have been used on a variety of US Navy and Marine Corps aircraft including the A-4 Skyhawk, F-4 Phantom II, A-7 Corsair II,and OV-10 Bronco.

 

And a search using Mk 11 mod 5 yields:

Mk 11 Mod 0/5 (Twin-Barrel Automatic Cannon, 20x110mm USN)

 

So it's a two-barreled cannon, based on the Crusader's weapon.

All,

 

What version and what type of gun system was this?

[mdatelmi 124]

OV-10D with M197 20 mm three-barrelled turret...if I remember correctly...

[+allenjb42 4,234]

I think they took it from a USMC AH-1 Cobra gunhip and designated it NOGS (Night Observation GunShip). Airfix made a 1/72 kit of it back in the day.

[+hgbn 91]

that paintjob on the NOGS has always been one of my all time favorites for the Bronco

[krfrge 742]

It is a really cool looking configuration.

 

Does anyone think there is a way to build that weapon system for the current series of OV-10s?

[+331Killerbee 840]

Twin 20mm Mk 12's..........A-4,A-1,F-8.....

 

All,

 

What version and what type of gun system was this?

 

3 Barreled Vulcan......

[charlielima 328]

Ah Huh. and there is the GPU-2/A also:

 

 

 

From the wikipedia gunpod page:

A lightweight gun pod fitted with the M197 20 mm cannon, the unit weights only 586 lb (266 kg) loaded with 300 rounds of ammunition. It has selectable fire rates of either 700 rpm or 1,500 rpm.[15] The pod is self-contained and powered by a Ni-Cad rechargeable battery, with sufficient charge to expend three complete loads before needing to be replaced.[16] This weapon has been tested on the A-37 Dragonfly and OV-10 Bronco.[17][18]

 

At 586 pounds makes the weight for the centerline on Daves OV-10A. It looks like the housing for the SUU-11 could be visually tolerable for this. How do I make one?

CL,

Make a Folder in Your Weapons called "GPU-2/A" and add a copy of the suu11.LOD in it. then use the Info below for the Data.ini.

Now You'll need the Gun Info and put it in Your "Gun" Folder.....

Now, Increase the load Limit on the Centerline Pylon from 600Kg to 800Kg in the OV-10A_Data.ini. It will give You below.

 

 

SUU11

 

SUU16

 

SUU23

 

Mk4 Mod 0

 

 

 

That's all I can think of, Short of making a new Model for the GPU-2/A.

Nice work 311KilleBee

[Rambler 1-1 9]

Damn, OV-10 with a Vulcan and sidewinders? Fresco hunting, anyone?

[charlielima 328]

How do I make one?

CL

Daah! Ask KillerBee.

Thanks I'll give it a shot.

I played with my data ini to add a single barrel 20mm gun to see how much of a difference it would make on targets. About 100% improvement on target kills. it also seems like wingmen where more likely to engage with guns with the one 20mm. One thing I picked up on the wickipedia gunpod page was that some gunpods are driven by ram air and some are electric. That made me sad. I have to dive my SPAD, AP-2H,or Black Pony to 300 KTS to get my favorite Gunpod to work?

KillerBee Did you whip up that MK-4 Mod 0 up or did you download it?

It looks good.

CL

[+Spillone104 553]

The MK-4 gunpod comes with SF2 and SF2V by default. ;)

[+Cliff7600 1,148]

I had the Mk-4 Mod 0 downloading the WoV expansion pack by eburger, running a 1st gen install.

 

The OV-10 is getting improved these days, thanks all!
