2.75 inch Rocket Launchers

[+yakarov79 11,082]

I think C and D ver are capable of firing Mk66 motors and Mk40. Diferences in intervalometer and starters.

 

Also i walk through my pics and looks like USAF did not use M229 on fast movers. Also never saw M257 and 259.  Looks like those long sticks are for rotary wing only US Army adn Marines for sure.

Other thing is that due weight limits Cobra in fact couldn't carry 17 M229. Limit was 12 rockets if I remember corectly on outboard pylons in Hog -4x M200/159 launchers.

[+ravenclaw_007 7,633]

so would it be better to remove the long warheads from the Air Force and Navy launchers ???

i was thinking about that all the time

 

 

about the LAU-3C and D are there any pictures of them available ???

i was thinking to add a LAU-3C in grey color with Mk66 rockets but i can not find any pictures to support that

[+Spectre8750 167]

This has some info on the different Launchers. Not sure if it will help.

i fixed the effects problem
since i was pretty sure that the effect was working before , i remove all effects that i added lately and as soon as i removed the PurpleWilliePeteGroundExplosion everything was back to normal

[+Spectre8750 167]

I'm excited to add the Rockets to the A-10 Pack. People will have to DL your Mod, I just want to add the entries to the A-10 Loadouts.

[+ravenclaw_007 7,633]

no problem as soon as i´m done with the Lau-3 i can send them to you

 

what about the LAU-3D with grey camo and what rocket should be used with it , the Mk40 or the Mk66 ???

[+yakarov79 11,082]

LAU-131/130 (same as Army M260/261 LWL) is current USAF launcher so it should go with Mk66.

LAU- model version A/A B/A C/A can be used only with older motors Mk40.

As for LAU-3D/A hard to say. should be able to launch both. Also it was issued already when Mk40 was at the end of production.  MK66 enter lines depends on MOD vers. on 1981MOD1  and 1985 MOD 2. Also launchers ver. D/A is around this years. Not sure but full contract was on 1985 for D/A.

As for M229 thing, its no longer in use, And i think US Army  was not using much m229 on mk66 motor.

In the US Army, Hydra 70 rockets are fired from the AH-64A Apache/AH-64D Apache Longbow using M261 19-tube rocket launchers, and the OH-58D Kiowa Warrior and the AH-1F "modernized" Cobra using seven-tube M260 rocket launchers. The AH-1G Cobra and the UH-1B "Huey" used M200 19-tube rocket launchers. The Navy uses the 19 round LAU-61C/A and the seven round LAU-68 D/A rocket launchers. These reusable launchers have an external thermal coating that greatly prolongs cook-off protection time. Full production of these launchers began in June 1985.

 

 

//=================================================================================================

 

I Get Confused Myself But There Are Mentions Of Longer Tube Variants Such As XM157B.

[+Spectre8750 167]

Mk40 or Mk66? These are a matter of age and replacement. Mk40's are older then Mk66.

 

The Hydra 70 family of WAFAR (Wrap-Around Fin Aerial Rocket), based on the Mk 66 universal motor, was developed from the previous 2.75 inch Mk 40 motor-based folding fin aerial rocket. The propellant grain is longer and of a different formulation than that of the MK40/MK4, however, the stabilizing rod and igniter are essentially the same design. The MK66 motors have a substantially higher thrust, 1,335 pounds-force (5,940 N) (Mod 2/3) 1,415 pounds-force (6,290 N) (Mod 4), and a longer range than the older motors. To provide additional stability the four rocket nozzles are scarfed at an angle to impart a slight spin to the rocket during flight. The Mk 40 was used during the Korean and Vietnam wars, being used to provide close air support to ground forces from about 20 different firing platforms, both fixed-wing and armed helicopters. Today, the OH-58D® Kiowa Warrior and AH-64D Apache Longbow, as well as the Marine Corp's AH-1 Cobra, carry the Hydra rocket launcher standard on its weapon pylons.

[+ravenclaw_007 7,633]

this are all the LAU-3 i have finish so far , please let me know if you find anything wrong or if you have suggestion about color or anything else

 

NOTE: to install delet all existing LAU-3 versions from your mod folder

LAU-3.7z

 

includet are LAU-3A / LAU-3C / LAU-3D with or without nose and tail fairings (covers) and all the MK40 rockets i have finish so far

the single LAU-3A is the replacement for the TW launcher with a white camo , i still look for a way to get some more LAU-3 launchers with a white camo in to the game

 

if you go to the weapon selection in game you will find the LAU-3 with cover right below the LAU-10 and the LAU-3 without cover on the bottom of the rocket launcher list

try them and let me know what you think about it , by the way i changed the color of the YellowSmoke.tga to a more yellowish appearance all effects work fine on my game

[+Nyghtfall 2,154]

Hi Volker,

 

impressive work! I really like those pods and the smoke-effects. :)

 

I did a quick test and found 3 things (Screenshots attached):

- if you look at the "exhaust" of the twin-pods 3 rockets on each pod are of different color than the others. It doesn't seem to be intended...the single-pods don't have that.

- on certain angles you can tractor beams. They seem to be visible, if rockets are in the pod. If the pods are empty they aren't there.

- all pods seem to have "Attachmenttype=USAF", "Nationname=USAF" and "Exported=false". I guess some sort of differentiation or "NATO" instead of "USAF" could be better here. If this is intended or still WIP just ignore my comment. :)

 

Keep up the good work!

 

[+ravenclaw_007 7,633]

Thanks for the quick test

 

- the twin-pods do only have 32 rockets that is the maximum the game allows thats why there are 3 rockets on each pod missing

- the tactor beam is strange , can you find out what particular rocket  or rocket pod is causing it

- the attachment type USAF is from the original made by the Mirage Factory i just keept what was there

[+Nyghtfall 2,154]

I tested several pods and combinations with unmodded planes and the tractor beam seems to be gone....so obviously it doesn't come from your great pods. Sorry for the confusion! :/

[+Spectre8750 167]

I'm not getting that tractor beam effect either, seems to be working great so far Ravenclaw!

LAU-5003 rocket pods (each with 19× CRV7 70 mm rockets)

LAU-10 rocket pods (each with 4× 127 mm (5.0 in) Zuni rockets)

[+ravenclaw_007 7,633]

yap , the LAU-10 are almost finish

 

by the way did the USAF ever use the LAU-10 ???

 

and i found a picture showing that the USAF is using the long warheads on fast movers , Mk66 rocket with M257 illumination warhead on a F-16

[+Spectre8750 167]

According to Wiki, not that I put much credence into there sources, but I'm pretty sure I remember that they do use them. But let me check my books when I get back home.

[+Spectre8750 167]

According to a Book I have Copyright 1986 Detail & Scale, I can only find LAU-68 7 Tube Launchers used. The Internet doesn't really have anything credible showing other Launchers, Not even the LAU-3.

Edited August 15, 2015 by Spectre8750

[+CrazyhorseB34 937]

Man this USAF attachment only is killing me! Urgg got to go through each one and add NATO, USN.

 

 

[+ravenclaw_007 7,633]

i just added the NATO to all lau-3 pods but to get it working i may have to add the export as well , i will try

 

why will you add the USN ??? did the navy use the LAU-3 ???

 

man i would be happy with a list showing me who used what

Edited August 16, 2015 by ravenclaw_007

[+CrazyhorseB34 937]

I was just testing them on an A-4!

 

Oops! guess your right!

[+ravenclaw_007 7,633]

i renamed the LAU-3 folders , this way the pods can be more easy selected , and i added all LAU-10 pods and rockets

 

NOTE: you have to DELETE all existing LAU-3 and LAU-10 folders before you install this new pods

 

LAU-10 and LAU-3.7z

 

includet are :

- LAU-3A  twin and single mount , green camo

- LAU-3C  twin and single mount , green camo

- LAU-3D  twin and single mount , gray camo

 

- LAU-10A  Triple , twin and single mount , white color

- LAU-10C  Triple , twin and single mount , white color and gray camo

- LAU-10D  Triple , twin and single mount , white color and gray camo

 

- 2.75 inch Mk40 rockets

- 5 inch Mk16 rockets

- 5 inch Mk71 rockets

 

the AttachmentType for the LAU-3 pods are still USAF ( i may let it this way)

the AttachmentType for the LAU-10A / C are USN,NATO for the LAU-10D  USN only , the reason why i add the NATO to the A an C is that i found in the F-4F weapons delivery manual the A launchers with Mk16 rockets

 

if you find anything wrong let me know

 

[+Nyghtfall 2,154]

First: thanks for your work! I like the new pods.

 

I'm no expert at those pods. But afaik in Vietnam the Navy used 19-shot Rocketpods as a common loadout on their Skyhawks. Some of them even get damaged while firing the rockets. Those pods were called Aero 7D. Some sources list LAU-3A/A or LAU-3 in brackets for them, so I would guess they are either the same or close enough.

 

I did a quick search and found a picture of those 19shot pods on a Skyhawk. I'm off to work now, but I will look for more and better pcitures later.
