Improved Cobra Armament Program (ICAM)
Posted by whiskey on Saturday, January 24, 2009 1:36 PM

Does anyone know what happened to the aircraft that was used to develop the YAH-1S "249" I have probably seen only 5 or 6 pictures of this aircraft my entire life and would like to see more. If anyone as any info on the where abouts or fate of these birds please let me know.

Whiskey,

Your picture really caught my eye.  It looks like a PROD or ECAS configured with a 4 blade Marine Corps rotor head.  I went to one of my key reference sites (http://tri.army.mil/LC/CS/csa/aahist2.htm#AH1S) and found the following information:

AH-1Q anti-armor version (1973) was the result of the Improved Cobra Armament Program (ICAP), to fill the operational gap left by the failure of the AH-56A Cheyenne program. The AH-1Q had an M28A1E1 turret, XM65 TOW/Cobra missile subsystem, infrared sight, and XM128 helmet sight subsystem (HSS). The AH-1Q was equipped to fire eight Hughes BGM-71 130mm TOW (Tube-Launched, Optically Tracked, Wire Command-Link Guided) anti-tank missiles mounted in a pair of two-round pods on the outboard pylons. M200 19-tube 2.75 inch rocket launchers could be carried on the inboard pylons. The AH-1Q was deployed to Vietnam in 1973, but was unable to carry a full weapon load in that environment, leading to development of the AH-1S Cobra. The AH-1Q was the first Cobra to feature the snub-nosed Telescopic Sight Unit (TSU).

YAH-1R prototype was the result of the Improved Cobra Agility and Maneuverability Program (ICAM), essentially an AH-1G with an upgrade to a T53-l-703 1800 SHP engine, transmission and tail rotor, but without the TOW missile system. A second prototype, the YAH-1S, was a AH-1Q upgrade with full TOW capability.

 For additional information and some excellent pictures of the AH-1S Cobra, go to Butch Lottman's AH-1S Cobra page and AH-1S MOD Cobra photos page.  Also check http://www.midwaysailor.com/photos/cobra.html for some AH-1F(MC) pics.  I found 1 pic of the YAH-1s at http://twdesigns.org/hueyhelicopters/history%20gallery/249.jpg.

Cheers,

 

Wade

Thanks Wade for the picture Wade, havent seen that one. I know the history of the a/c and its successors, which is why I am wanting more visual aids. I would love to try and tackle the subject in 1/48.

Whisky, if you can find a 1/48th Bell 412 and replace the cobra transmission with the Bell transmission and rotor system and modify the cowling, you will come real close to having a replica of the four-bladed cobra. I saw the real bird I believe either in the late 70's early 80's at Test Activities at Cairns Airfield and I remember thinking that they had basically used the same rotor system as the Bell 412. I would assume Bell used as much stock stuff as possible because they would not want to spend their own R&D money on something that was not paid for by the Army. I believe the four-bladed cobra was a demonstration model Bell was trying to sell the Army. I think they demonstrated it at Rucker at the same time that the AH-64 was still going through its program development and acceptance. My timeline might be a little off, but that is what I remember about the actual aircraft. It was just a demonstration improvement offered by Bell and not a requirement. It was more of what we call an (unsolicited proposal).
