M386 truck based rocket launcher
The AFV ASSOCIATION was formed in 1964 to support the thoughts and research of all those interested in Armored Fighting Vehicles and related topics, such as AFV drawings. The emphasis has always been on sharing information and communicating with other members of similar interests; e.g. German armor, Japanese AFVs, or whatever.

Hi Guys, The Honest John was a ballistic rocket weighing over 5 tons fired from a truck mounted ramp. It carried either a conventional HE warhead or an Atomic war head. It was the first tactical atomic weapon. It was propelled by solid JATO fuel which blasted off in a 4 to 5 sec burnout. Once launched it could not be controlled. Because of its large fin surface area , correction for surface winds was very important. It's range was about 17 miles. I served with the 100FA Battalion attached to the !st Cav in Japan in 1954. We airlifted all over the Far East including Okinawa, Thialand ,Hokkaido and an amphibious landing of Iwo Jima with fleet support . Because of the truce agreements we could not be stationed in Korea with atomic weapons but we were ready to go if hostilities broke out. It was replaced, I believe, by the Corporal missle. TomT

Originally it was the Truck, 5ton, 6x6, Short Launcher, GM, Honest John while the M289 Long Launcher (which it replaced) was still in service

yep, that is right. it was shorter.
found out more about it, the M386 had the shorter ramp. The A-frame mounted on the front bumper to support the long ramp of the M289 was deleted on the M386.

Hi Folks!

Hey Folks!

That truck is NOT a duce and half, that is a five ton. Look at the gap between the rear of the front tire and the fender. There is room of the driver to step in between the tire and the rear of the fender.

Roy is right...and in fact, one modded version is rated at 6 tons. Figures, since Tom established the missile itself weighed over five tons.

it was originally an M139C, then M139D - I assume the change came with the different launcher styles.

The M139 itself is an uprated version of the M36 2.5-ton LWB chassis which is why it is often mistaken for a 2.5-tonner.

Cool

Hi Jim! Hi Folks!

The standard five ton cargo trucks had an axle gear ratio of 6.443:1
The M-139 C, D, and F models used for the Honest John system had an axle gear ratio of 10.26:1 for improved off-road traction. That may make two items that make the Honest John trucks different.

Sorry Jim, I have disagree with you on that point. Sad
The M-139 is a modified M-55 which had a 20 foot cargo box which was designed to carry engineer bridging equipment.
The M-55 is a modifed M-54.
The M-54 five ton 6x6 cargo truck was developed as a replacement for the WW II four, six, 7 1/2 ton series of trucks.

The M-54 FOVs is very similar in design and appearance to the M-35 2 1/2 ton series of trucks. Looks is ALL that the M-35 FOVs and the M-54 FOV's have in common. The M-54 is a total different design and the M-55/M-139 is not an upgraded M-36.

My take on M-35 vis M-54 trucks.

If you can see an axle ratio gear externally Roy your a better man I am... Crying or Very sad

I was following an explanation from a pocket history by an american general called Toftoy.. but I'm beginning to think he was actually talking about the prototype launchers and got them confused with the production vehicles...

As I recall, the launching ramp was mounted on a 5 ton truck. The National Guard museum in Lawrenceville NJ has an intact rocket and launcher they plan to refurbish. An Honest John unit from Cape May served in Europe. There is a ramp and rocket on display off the Garden State Parkway in Cape May NJ but no vehicle. Another interesting fact on this rocket is that it was covered with a tight fitting quilted electric blanket for hours before a lauch in order to maintain the proper temperature for the solid fuel! Don't know how that would work out in a combat situation. Somewhere in my photos I have a picture of that setup. TomT

I think I spotted that rocket in Lawrenceville. It was in a fenced off area with a lot of other aging material, including a Gamma Goat.
