Back Boeing-Vertol ACH-47 "Armed/Armoured Chinook"

Boeing-Vertol ACH-47

In late 1965, the first Armed/Armoured Chinook was officially rolled out and testing was begun. The Armed/Armoured Chinook used its payload capability to advantage by mounting an extensive array of armament, as well as armor to protect the crew and vital parts of the aircraft against heavy calibre ground fire.

Mounted on the nose was an M-5 40mm Automatic Grenade Launcher. This turret-mounted weapon was controlled by the copilot, who was able to cover an extensive area on either side of the flight path. Complementing this nose turret, pylons on each side of the aircraft carried fixed forward-firing weapons including a 22mm gun and either a 19-round 2.75 inch rocket pod, or a 7.62mm high-rate-of-fire Gatling machine-gun.

The flanks of the aircraft were protected by four gunners stationed two to either side of the cabin. Each of these gunners was provided with either a 7.62mm or 12.7mm calibre machine-gun on flexible mounts. Another gunner was stationed aft with the same type weapons mounted on the rear loading ramp. From this vantage point, the gunner could protect the aircraft from ground fire after the aircraft had passed, a capability not present in previous armed helicopters. This aircraft carried a ton of expendable munitions.

The Armed/Armoured Chinook was provided with a new type of steel armour plate which was built into the crew seats and protected their torsos. Other steel plates protected components of the aircraft. The rugged components of the Chinook and extensive dualization of systems, combined with over a ton of armour plate, assured a high degree of survivability for the aircraft.

The first ACH-47, "Stump Jumper", was destroyed while taking off for a fire support mission. It crashed into an unarmed CH-47, and both were damaged so badly they were scrapped. Co$t of Living was destroyed when the retention pin on the right 20mm cannon snapped. The cannon fired up into the forward rotor, and the helicopter crashed, killing the eight-man crew. Birth Control received serious hits during the battle of Hue and was forced to set down in a rice field. The crew of Easy Money risked themselves and their helicopter to save the crew of the downed chopper. Easy Money was then removed from service and was recently discovered and restored.

Cindy, does it help if they are qualified to fly a Chinook too?

My buddy, Jim Gustafson, was a crew member on "Co$t of Living." Jim was called home May 1967 for his mother's funeral. While in Montana, the entire 8 man crew of "Co$t of Living" were killed when the big bird went down. Gus always said he mother's death saved his life. He joined his folks November 1, 2001. Sure miss that big Norwegian.

The Armed Chinook was known a "Guns A-go-go". Unfortunately, they were A models and were limited in the load they could carry and tended to be cumbersome and slow. They would enter a dive and start firing their ordanance and would slow to 50-60knots from the recoil of the weapons. This would make them vunerable to ground fire. They would be slow to pull out. Google the 1st Air Cav and check out the 228th Aviation Battalion. You should find some pics of actual a /c use in Vietnam. They had a short life span.

Does anyone know where I can find, or has, information on the design team at Boeing Vertol?

This chopper is awesome!My favorite ocidental one.
A real pity that it isnīt used anymore (the ACH version)

Yep; I built the four of them and later, as fate would have it, I was with Boeing in Viet Nam on a field assignment and stationed with the 1st Air Cav at An Khe, when three of the Gunships arrived in August of 1966 (Very few people knew of their existence and were surprised). I suggest Mr. Rivera write to Boeing Helicopters in Philadelphia about the Award to see if they can help. The Armed Chinooks were the B-17s of their day but their cost was too high (back then a std Chinook cost around a million dollars whereas the Armed Hook ran around 4 million; when I left Boeing in 1988, "D" models were going for around 13 million!

Hello, I was an original gunner /crew member on Birth Control. In the year 1966 while field testing the A /ACH-47A IN VIETNAM the crew earned the Boeing /Vertol Rescue Award. I have recently lost or misplaced it. The award means a great deal to me. If possible, please replace it. thanking you in advance, Fondly, Daniel J. Rivera
