The XM1 was a scary fast tank even going cross country. I got the chance to pace one as it was fording creeks and rolling over small trees back around 1980. I was driving on a paved road and I found myself speeding well over the limit to keep up with the metal monster. I can't tell anyone how impressive these things are when your cruising next to one... Just their size and jet engine sound is beyond impressive... then watching small trees felled like a scythe cutting grass and the way the thing 'floated' across a small creek ravine with it's treads going down and the tank staying essentially level changed my entire comprehension of what a tank could do. I can't remember exactly how fast I was going, but I can say it was well above the rated specs on the current M1 Abrams. I suspect the XM1's were lighter and not fully fitted out when I saw them. Tanks are cool in static displays, but they are another thing entirely when your driving right next to one at highway speeds.

The evolution of tank designs throughout the cold war is very interesting indeed. A lot of the engineers and techs had WW2 and Korea experience and it showed in the various designs. It was always hit and miss, but fortunately was more hit than miss. One of the more atrocious misses was the M-551 which was supposed to support the airborne forces. Didn't work very well, particularly the missile system. The great thing is that the MBT-70 led to the great designs of the German Leopard and American M-1. Thanks for the educational upload, Sofi. Great way to spend some time today.

Great info. I once interviewed for a position at the Chrysler Tank Arsenal. I really wanted to work there. I remember it as one of the best job interviews I ever had. I didn't get the job, which turned out to be good. It closed a few years later. I ended up working for Chrysler in auto manufacturing. A number of people from the Arsenal ended up transferring to where I was when the Arsenal closed. I still wanted to work there.

[@mruofacat]

Chrysler lost the contract for production due to poor performance. The M-1 is welded and the UAW workers at the Lima Tank facility could not produce tanks on time because of the faulty welds that had to constantly be reworked. My AOAC class toured the Lima plant shortly after the contract change and General Dynamics was producing zero defect tanks on schedule. Side note. We had Allied officers in our class so the part of the factory where the turret armor was produced was off limits to us. I was pissed.

[@ricklinehan7176]

@@mruofacat Interesting "Facts", however, Chrysler did not lose the contract. Iacocca sold Chrysler Defense to General Dynamics in 1982 for $348.5M because Chrysler needed cash after posting a $500M loss in 1981. It was a cash up front buy that Chrysler needed. Those same UAW workers, that you said couldn't weld, built everyone of the M1 Tanks. Detroit Arsenal was only doing component production with full assembly at Lima. Chrysler Defense became General Dynamics Land Systems. Lima was rated to produce up to 4 M1s a day with the support of Detroit Arsenal Tank Plant. Production obviously never went to that level with end of the cold war. It was a great place to work and a lot of cool "toys" to see and "play" with for sure. Never, ever, park your car at the end of a parking lot row up at Sterling Heights HQ (used to be called Central Office Complex back in the day) when the prototype shop guys are going to be out testing vehicles on the grounds. :)

I restarted my hack, mediocre modeling career during COVID. I put the M-24, M-47, M48 and M-60A2 and A3 next to each other. It was easy to trace the lineage from one generation of tank evolution to another. Suspension, engine deck, stowage, etc, etc. all showed evolutionary advances. Then, I did a 1st generation M-1 Abrams-- wow-- Rob's right-- totally threw out the history up to that point and started with a clean sheet of paper! The Abrams looks nothing like it's older cousins. Sure, I could "see" it when I looked at photos, but actually assembling it (in 1/35) made a huge difference in understanding the change a bit better. Thanks for an awesome video! I'd love to see/hear more about the evolution of the T-29/30/34 into the M103 and even better, the different versions of tank recovery vehicles. There are also a lot of weird looking "battlefield taxis" from the 1950's that were ancestors to the M113 series.

The MBT70 as being a US-German collaboration can thus be found in Germany's tank museum in Munster.

Regarding the German engines, yes, this company belonged to Daimler (Mercedes Benz) in the past, but it is called MTU, a specialist for large scale and military diesel engines.

[@MetalGearArmA]

Actually MTU is the original spiritual successor of Maybach company , since they used to build these amazing engines during WWII and continued building these engines in the cold war under the brand name of MTU: Maybach Motoren und Turbinen Union, however what is funny is that Mercedes Daimler decided to sell MTU to Rolls Royce Holding, but keeping the Maybach brand under them for their ultra premium cars which is known as Mercedes-Maybach nowadays, also Rolls Royce sold their Motor company to BMW which that means both the original factories are now under the control of Rolls Royce Holding but the motor companies are under the German car manufactures

"King of the Killing Zone" was, to me, eye opening. I bought it and read it shortly after it came out (I think I still have my copy ... somewhere) and highly recommend it. In it, as I recall were some concerns about how the turbine engine and drive train would be able to handle what was considered unlikely at the time, use in a desert environment. M-1 was designed more for use in Northern Europe for a 'Fulda Gap' scenario with combined arms support from mobile artillery and another as yet untested system, the A-10 Thunderbolt II. My Dad was WWII Army and transitioned to the USAF in the 1950s. I was Navy and we used to kid around and pick on each other as you can imagine, but when Desert Shield / Storm took place he was proud of the fact that both Army and Air Force "had it all in one sock" and "made it look easy" (I know it wasn't.) During the ground campaign I was bobbing around 20 miles off Kuwait as a watch supervisor in the Intel Center of the Flagship of the Amphibious Group (30 ships and nearly a full Marine Division.) M-1 Abrams and A-10 and their crews performed much better than any of us could have dreamed.

@@mruofacat Not quite. The M-60A2 wasn't a "Super Patton". It was designed to counter the Soviets fielding tanks and tank-destroyers equipped with ATGMs that could out-range tank guns. It was never meant to replace the M-60A1+. The M-1 program was a completely different project that was designed to replace the entire M-60 fleet. By that time the Army had completely gotten the gun/launcher idea out of its head.

The Leo 2 had issues with the hull being penetrated by mere I.E.D.'s in Syria. Imo the composite layout of the Leo's hull is less effective due to the angling (which is a liability in terms of composite design). The Abrams hull stacks the composite so that an in coming round hits the full thickness of composite on the face of the plate. The upper plate is so angled that it's basically flat but theres more than meets the eye. The upper plate is actually designed to snap penetrater rods upon impact. The gunner sight of the Abrams is also placed above the cheek armor removing a liability or weak spot for composite. The 2A6 is a good tank though.

I actually have a discord friend who was in the US army as a 19 kilo. He went from using the M-60a1, M-60a2 that used a 152mm gun, M-60a3 and the sheridan. He then moved to the M1a1 abrams and finally the M1a2 during the gulf war and desert storm before retiring. He also told me he used the XM1 but didn't tell me much.

You're doing the lords work Sofus.

I wonder if that’s the same MBT-70 that used to sit near Disney Barracks at Knox, by the shoppette.

[@JarOfDirt.]

Damn these tanks look amazing!

[@shanechapman3567]

I would have liked to see this thing a mainstay mbt would have been Soo cool

[@OrtadragoonX]

The MBT-70 had so much potential. If they had equipped it with a 120mm normal gun and replaced the engine with the gas turbine the XM1 used it could have been a damn fine main battle tank.

Mahalo Sofi; very informative. Hope you're healed enough to get back on the range. Aloha

The Continental AVCR-1100 is actually unrelated to the AV/AVDS-1790 series present in the Pattons. It was developped by putting variable compression pistons on the AVDS-1100, a brand new engine developped along with the liquid-cooled LVDS-1100 to potentially power the T95 medium tank (the intended X-diesel had failed and the other engines proposed weren't good enough). The AVDS-1100 was retained for the post-T95 studies like MBT-MR and eventually it became the AVCR-1100 for the MBT-70. After the MBT-70 failed it was modified again into the AVCR-1360 which unsuccessfully competed against the turbine for Abrams.

Probably the one missing Abrams family member in the collection is the XM-1 General Motors which is somewhere in the US as it was last seen in California missing parts after being sold off from the Littlefield Collection. Overall hyped for a open house of the NACC and great vid on the Abrams

[@tinture2822]

Actually there are several missing links in this lineup. The Chrysler validation prototype 1975 turret designed before BRL-1 Armor, the Chrysler validation prototype JE 0001 and JE 0002 automotive test vehicles, and the XM1 GM validation prototype.

[@carol7311]

@@tinture2822 those would make great additions to the collection if they can find them. Can someone suggest this to the NACC so the search can begin to reunite the Abrams family like that of the Tiger Collection from Bovington?

[@williamfullingim7668]

Are refurbished tracks an episode in themselves..? Could be cool and fun.

The M60A2s had a lot of first that was used in the M60A3s and the M1, the M60A2s was the first main battle tank to use the Laser Rangefinder, fire the sheleighly missile, combustible main gun rounds, fire on the move but not very fast, and some others first that I can't remember what we called them, been over 40 years that I crewed the M60A2. Lol...
