Inside the Chieftain's Hatch: XM808 "Twister"

XM808 was a proof of concept vehicle created without requirement by Lockheed Missile and Space. Three were built for the Army for testing for lunar operations, the fascinating armed and armored version is found today at the US Army Armor and Cavalry Collection, Ft Benning, GA.

    Two transmission shifters so you can put one in neutral. I'm betting they also hoped you could "trailer" the main body and run on the front engine only. The crew cabin would use the rear engine for electrical. So there are situations in which you'd be in rear-neutral idling to run the hydraulics and front engine in drive for roading. Makes it even crazier.

    It reminds me of a logging skidder. If you have never seen a logging skidder, it is a very specific vehicle designed to drag or "skid" logs out of a forest. For this concept, they added 4 more wheels, changed the chassis a bit, added engineering for higher speeds, added a weapon mount, and painted it green. Still, if they took this concept and applied more current engineering technologies and safety/comfort features, I could see something like this being very handy for mechanized recon missions in places where good roads are a luxury. Thank you for going over this machine. I learned something new today for sure. :-)

    Log skidders are an interesting bunch, the early ones were literally steam locomotives on treads. The Lombard steam hauler had an unique tread system, a tread within tread to eliminate friction in the days before oil-based lubrication was available, and it worked pretty well. The thing moved at 4mph but could drag 300 tons worth of logs. I should mention I came across an abandoned Lombard deep in the forest I was hiking in some years ago, the thing was pretty intact despite sitting there for nearly 120 years and got me interested in log skidders.

    I actually built log skidders for J. I. Case. I believe they only built them a few years. Possibly because of high maintenance of that bearing that let the rear "twist" separate from the front. The articulated bearings worked just fine. The rear fenders (the part that you would pull a log into) were a half an inch thick. I dropped one on my finger (only about a two inch drop) and I can say, they are HEAVY!

Looking at the mechanical transmission complexity, this has to be a design that would benefit hugely from electric transmission, with the engines just driving generators and a motor in each wheel hub. The ENGASA company from Brazil had a patent on a slighty different form of walking-beam suspension, and sold large numbers of them, both on armoured vehicles like the Cascavel and Urutu, and also on unarmoured 6x6 trucks.

    Thank you for the video. I actually got to drive the twister, in the tour video, at Fort Hunter Liggett in the 1970s. It was a blast to drive off road. One feature was that the steering hydraulics ran off of the front engine. There was a axle pump, on the rear section, that was a backup for the steering, in the event the front engine was not operating, that would provide hydraulic pressure to operate the steering once the vehicle was rolling about six miles an hour.

    Everyone seems to forget Electric engines are heavy and expensive. And hub motors are terrible mostly due to Unspung mass. Springs make your ride comfortable and shove wheels back onto the road faster than gravity would allow. Heavy motor wheels take longer to get back onto the ground. And the amount of electricity to run any 4 of those wheels? High. The machine as designed could have saved a lot of power losses through better transmission layouts and removing geared power transfer. However They were trying to print 4 copies on the cheap as proof of concepts, not as final delivery machines. So easy to print cogs shoved inside some metal bars are easy, but individual drive shafts for all four rear wheels? expensive, but lighter and lower power losses.

    Given the number of gears in the rear portion of the vehicle, it is unsurprising how loud it would get while riding in it. To save costs, they would have been spur gears, so they would have been noisier than helical gears. Helical gears would have been less noisy, but the fuel economy would be even worse. This is one of the few vehicles which would have been better (not cheaper) if Ferdinand Porsche had designed the power train, as running electrical conductors to electrical motors in the wheels may actually be more efficient than all of those spur gears.

Knox, KY in the early 1980s. Our people used converted/adapted M113s for about 98.99% of their training with the balance being "humping and ground mounting" their tubes. Those old tubes would break a healthy Missouri mule's back by themselves much less all the other gear Mortarmen had to carry.

    When I served with 2/2 ACR in Germany we had M114A1E1 scout vehicles. You don't have 75 rounds of 20mm although as mentioned there is an iron sight on the gun so you can aim to some extent from inside the turret. The gun is very accurate at least out to 700m as you could hit a 2x4 at that range without using a sight, just the tracer. The ammunition feed includes 25 rounds in a canvas chute from the loader - a separate device from the gun that sits on top of it and mechanically loads it, hence the high rate of fire ability - to the 50 rounds in the ammunition bin. When the gun is down to 25 rounds it will stop firing. You are supposed to load another 50 rounds, from separate ammo cases each holding five rounds, by hooking ten of the five round belts together, starting with the belt in the chute and then connecting that to the 45 round belt in the bin you put together. If you consider it to be an emergency you hit a switch and you can fire off the 25 rounds. However, you then have to take the ammunition loader off, make a chain of 30 rounds (6 ammo boxes), feed the belt through the chute and into the loader then into the gun, fasten the loader down and then hook the 50 round belt in the ammo box to the belt in the ammo chute and you are ready to go. About 30 minutes to do that while standing/sitting/laying on top of the vehicle. You really don't want to fire more than 50 rounds. The gun is good. The feed system not so much. Oh, and the recoil at full auto when you fired off 50 rounds would lift the tracks at the front of a M114 off the ground. Not sure what it would do to that armored car and pretty sure you didn't want to be moving when firing for a reason even better than not hitting anything. Hope I remembered the ammunition reloading. Never did it. Only fired the 20mm once in training 50 years ago. Oh. In 1973 we turned in our M114A1E1 for M551A1 on a 5 M114 for 3 M551 ratio. I would like to see a review of the M551.

    So I remember in the early seasons of the history channel show Ice Road Truckers THIS VEHICLE was mentioned as the inspiration for an idea on how those semis could bring their own help getting up some of the steeper hills during heavy snowfall. . Essentially the idea was a vehicle chassis with no cab that could be bolted into the front of the tractor section and pull it up the hill. This concept would be considered easier than the current Buddy system where one semi would disconnect their trailer , and then chain up to the other semi and trailer and then pull it up the hill . They would then have to repeated the process to get the other trailer over the hill then get everyone sorted out again. A device like this could ride along in a half filled vehicle, and then one by one pull everyone up the hill before being returned to its storage. It also could be stored in a small but heated storage location near hills that are chronically bad and deployed when semis are getting stuck

From what I remember, the 20mm on the M114A1E1 had a metal tube below the gun cradle that you could get a rough sight from looking through the cupola window. Am thinking if the M114 had just one of those engines it would have been a huge power difference over the Chevy 283. Also, always though it would have been better to keep the .50 instead of the 20mm, which still would have made other apc's stop and think a bit while we ran the other way, the combat load of 400 for the 20 would be gone in 30 seconds if you could link all the ammo fast enough.
