The unique Christie suspension system took the tank world by storm in the early 1930s, and tanks equipped with it remained in production until the very end of WW2. Yet, his home nation, the USA, entered the war with bogie wheeled volute sprung tanks, not the big-wheeled coil-sprung speed demons that Christie was building.
This was the result of a multi-year testing process, comprising more Christie-type vehicles than not, while Christie wrote himself out of the picture for most of it. By reference to test reports, we can see what happened.

The US Arsenal was working up the Stuart design at the same time which made the US Army realize that it's vertical volute suspension was superior to the Christie suspension due to being less complicated, didn't take up interior space and was easier to repair or replace. The one holdover from the combat car design was using the radial aircraft engine since the crews and mechanics like it plus those were cheap and plentiful as obsolete engines stored in the warehouses of commercial aircraft operators.

It looks like the Christie suspension was an idea that would have very good in the 20's to mid 30's given the reliability of tracked vehicles at the time. As tracked vehicles became more reliable in the mid to late 30's it was superseded by other designs. Also, as armies world wide gained more experience with armor certain design criteria became standard such as the 3 man turret. These tended to impose a minimum working volume within the hull. Suspension systems that took up less space would obviously be given a good hard look as they might make for a smaller overall vehicle. It seems like much of the criticism of the US Army not adopting the Christie suspension is based solely on the speeds the designs were capable of not on a holistic assessment of the vehicle as fighting vehicle. If other designs are just as effective as fighting vehicles but are cheaper it does make sense to adopt the cheaper design even if the top speed is not as fast.

I think it depends on where you're willing to spend your money and resources. Both the British and Soviets had great success using the Christie suspension on tanks, right up until the end of the war. Both the British Comet and late-model Russian T-34 tanks were still using it, though it tends to get forgotten about as vehicles pass the 40 ton mark.

@@Senbei01 To be fair though, the Russians were trying to get rid of the Christie suspension and make the T-34M with torsion bars instead, but with the war breaking out it seemed pointless making such a radical production change and endure a drop in production numbers while the Germans were coming right at them. The brits on the other hand still went with some variation of coil springs for almost everything, and once they got to Centurion, which is without a doubt just too heavy, went with Horstmann bogies. British suspension design generally seems to be a bizarre struggle of using everything and anything as long as its not torsion bars.

All that suspension has to go somewhere. The Army decided to put it inside the tracks, so it's external of the tank. Christie's design had it internal, thus taking up valuable crew room. It's one reason the T-34 was so cramped. Not to mention the sloped side armor.

Oh! Thanks so much for clearing this up for me and so many others! I also wonder about the development of the T-34 now, it essentially looking like a widened bt-5 or 7. I also wonder why that as there was more weight and less space; the additional protection to the sides with the spaced armor and springs and such weren't considered as a wanted feature. Even with Torison bars however, you lose floor space, and don't really gain protection for that loss. Though this was played out in crusaider in which you had to take off so much to change a spring. That combined with doctorine, no real reason for them to be overly fast to get isolated from support anyway. Good stuff.

Russians did it first though. Russians absolutely loved the design and had followed through with it since the 1930 , improving it's design gradually, first n the BT series tanks which later changed to A series , which later became a T34 tank in 1940. The soviets had contacted Christie in 1930, in 1931 first tank designs were shipped to the USSR, and in 1932 they were made domestically and started improving it's design each year after that.

As I understand the British also at first missed the mark with this design since they only started to develop tanks based on Christies design after British military delegation had witnessed demonstration of the Soviet BT tanks in Soviet Union in mid 1930s. This meant that the British started developing these tanks only in late 1930s and had no significant number of such tanks before the fall of France 1940.

"Gumbo mud"... brings back memories. I don't remember such mud at Fort Riley. What I do remember is 6" of packed dust covering a sheet of rock we needed dynamite to blast through. But Fort Hood and Fort Polk had 6" of sod covering the clay. When you add water to the clay, it takes on the swirling colors of gumbo. Left to dry on the tracks of a tank, it became 'concrete'. There was much 'fun' to be had at the wash-rack after time in the field; tanker-bars and fire-hoses, then shovels to get it out of the concrete run-off ditches. And to Paul R. Ward's "...you sink right down into it and ARE NEVER GETTING OUT !..." "Sir, this bridge-layer is top-heavy and weighs more than you think. It will get stuck in the mud." "Sergeant, it is only two inches of mud. I'm ordering you to not hold up the column." The only thing more dangerous than the ignorance of a 2LT is the know-it-all arrogance of a 1LT.

Gumbo mud at Ft Riley (14:15) - from the Wikipedia entry on “Gumbo (soil)”: Although gumbo soils are exceptional at water retention, they can be difficult to farm, as precipitation will turn gumbo into a unique muddy fiasco that is challenging to work using large commercial farming equipment. Avoiding tillage of this type of soil, thru "no-till" farming, appears strongly correlated to higher yields versus more traditional tilling practices.

Pretty cool, you can see the outlines of the T-34 in the early Christie tanks. People call any tank with that type of suspension a "Christie tank", but in the case of the T-34, it is a direct descendant of the entire machine he built. Particularly the later improvements, look at the rear view at 7:45. it has the same slopes, the same twin exhaust, same overall shape as T-34. T-34 is a direct descendant of the BT series, and the BT is directly taken from the 1920s US designs. Also understandable that Christie resisted turrets. Seems wrongheaded to us today, but remember this was only a decade or so after the first WWI tanks rolled out, so what a 'tank'ought to look like was not established, nor was it clear that turrets were going to be a primary attribute of a 'tank' later.

John Walter Christie was an interesting if brilliant engineer whose designs were heavily influenced by his initial experience of automobile racing, to include the French Grand Prix in 1907. Although history tends to be a strange bedfellow when considering that Christie's designs found success in the Soviet Union and the U.K., rather than America. The man was ahead of his time, and yet never truly understood the basic doctrine of speed, armour and firepower.

Ft. Riley has local access to gypsum rock and at the time happily used it to "improve" their unpaved roads on the base. But gypsum breaks pretty easily, and when you have trucks and equipment running over gypsum rock, you get gypsum powder, which is finer than flour. When gypsum powder gets wet you have gumbo mud. If you get a half-inch of rain it's a quarter-inch layer of grease on a hard road and you helplessly slide all over the place. Your steering is irrelevant and so is the direction your wheels are turning. If you get five inches of rain, you can sink up to your axles in it, and no matter how you spin your wheels you don't budge. Gumbo mud may refer to different things in other places but around Ft. Riley it literally has the texture of 120-wt grease.

It almost seems that through all the testing. They found it better to separate the track vehicles from the vehicles with tires. Look at the Greyhound and the M18 Hellcat?? I think if you want speed. A wheeled vehicle is a better option than tracked vehicles. But of course its going to be down to what your looking for and what capabilities you want.

Interestingly enough the M18 Hellcat tank destroyer's original specifications called for a Christie suspension. Instead Buick engineer's went with their innovative torsion bar suspension which provided a much more stable ride at speeds approaching 50 MPH. The Hellcat was considered the "Hot Rod" of WWII while capable of reaching speeds of 60 MHP.

Buick's first Hellcats could do 60 mph since those used two Buick V8's. Ordnance decided it would be better if it used the same R975 radial as the M4's.

"Gumbo mud" Gumbo is a famous Louisiana soup characterized by its great thickness en.m.wikipedia.org/wiki/Gumbo. In reference to soil or mud it is "a tough, dark-colored mass in a high degree plastic and clay-like, yet sometimes consisting chiefly of silt or very fine sand. It is very sticky and difficult to till when wet, and when dry breaks into hard cuboidal lumps. See gumbo clay." www.finedictionary.com/gumbo.html. Keep learning American, my friend.

The Army always had problems with Christie not building what Ordnance designed to their specifications. Christie did make the few 1928 models for the Army but without turrets or machines since he didn't design ordinance systems. The Army gave American -LaFrance a contract to build 5 for $200,000 then got pissed off after the company ran out of money after completing 2 or 3. The Army paid more to get the full 5 then stopped doing business with them until the US entered the war.

I quite like the idea of mixed suspension. The long travel Christie suspension on the front road wheel would give good step climbing and less space consuming suspension on the rest would not significantly reduce obstacle crossing ability. I am a little surprised the cavalry did not go for armoured cars. Using large wheels with all or at least most driven would have nearly as good cross-country performance without all the messing around adding or removing tracks.

@ALEX HUANG That is why they called their tanks “Combat Cars.” I am saying that a proper armoured car might have been better. Ideally something like the M38 Wolfhound, granted that is 10 years more modern but how difficult was that technology the the mid 1930s?

@ALEX HUANG Sure, but what price are they paying on roads and level ground? They were considering using the wheel/track system primarily on wheels, despite only 2 of the wheels being powered. The M1 armoured car was bad cross country, but that was just an armoured truck with unpowered front wheels and small wheels. Bigger, or at least more, wheels and all powered would be almost as good as tracks in difficult going and dramatically better on good going. Retractable metal wheels like the Panhard EBR would have been interesting.

Wheels versus tracks--the US Army tried "both" and found that the convertible wheeled/tracked tank brought complexity without much performance difference. Comparing the Stryker family to these early tanks is comparing modern pick-up trucks to the Model T, but there's sometimes advantages to wheels and sometimes advantages to tracks. en.wikipedia.org/wiki/Stryker The desire to have "rapid strategic mobility" seemed to favor wheels--and tracks seem to have better cross-country mobility as well as the ability to weigh more and still remain mobile. The Christie convertible wheeled/tracked tank didn't work out well enough because a tracked tank could carry more weight (armor, guns, whatever) and still maintain off-road mobility but the combination tank was limited to wheeled tank weight class whether configured for wheels or tracks.

Seems rather odd to me that the criticism is that they took their time testing & developing various options to determine the most ideal solution - instead of just blindly accepting the extraordinarily compromised Christie design Also, history yet again proving that convertible "do everything" designs are a complete and utter waste of everyone's time - often times, it REALLY IS worth designing and producing two different ideas to cover two different needs, instead of trying to make one that can be converted to do either. Or, just accepting that one of these needs(high speed cross country travel - just haul the damn things there if it's really such a distance) isn't actually legitimate in the first place... ...the convertible tank, a solution looking for a problem...

RyTrapp0 we have the benefit of hindsight but at the time there were a lot of “good ideas” going about from multiple turreted land battleships to two man tankettes which would swarm all over the battlefield. The wheel/tracked idea was quite common as the tank could be driven to where it was to fight then changed to tracks rather than rely on rail or lorries that weren’t that large at the time.

@@johnludmon7419 The US Army got excited over Christie's 1929 design due to being blazingly fast when everyone else has low speed tanks. Christie never bothered to design weapon systems or turrets for his tanks yet did suggest a forward firing hull mounted cannon in the front of the 1929 by fitting a section of pipe with bins for ammo stowage inside for the gunner with the driver sitting behind him. Walter said the low profile tank (was under 6 feet in height) would be hard to see and hit as it raced around behind enemy lines shooting things up. The Army had him make some more that Ordnance fitted with a turret holding a gun to put thru rigorous testing. The crews liked them because those were fast even when going up long slopes so the Army hired American-LaFrance to build some more using a design worked up by the Ordnance engineers. A-F was given $200,000 to build around a dozen and after two years, had only made 5 before running out of money. In the end, the Army decided it would be best to use a simple suspension like the vertical volute bogie in combat since it was more robust, easier and faster to repair and could still support weight with broken springs.

But that's not to say more substantial helmets aren't better, good enouth does not mean best.

US wanted tank development, which as Chieftain pointed out was very limited intra-war, to be unified rather than diluted in different directions -- sensible enough. While the cavalry wanted tanks, the Infantry _needed_ tanks, so they were given control of tank development. But, as Chieftain noted, the cavalry just called the tanks they wanted "armored cars", so the army-only restriction didn't have much actual effect.

it was not the congress who forbade the cavalry to have tanks, but rather military thinking and WWI experience there were armoured cars in WWI, most of which were crewed by cavalry once the horse proved to soft to charge under machine gun fire, the vehicles were light and (relatively) fast which was perfect for the usual roles of the cavalry (recon, skirmishing and exploitation). the tanks on the other hand were slow, lumbering giants, heavy beasts of steel with guns poking out of every side and provide a hail of fire to help the crunchies cross the no man's land, there adapted to the infantry style of fighting of the time, which could be (overly) simplified to facing the enemy and locking horns with him. this experience influenced the interwar naming conventions in some countries, thus the cavalry had combat cars while the tanks were reserved to the infantry, France was in the same boat, the most famous french medium tank of WWII, the S35, was in nomenclature a cavalry combat car, a pretty weird combat car if you ask me, but one none the less

The US Army didn't bother with designing tanks after WW1 and instead purchased tanks made in other countries to test and examine. Patton and Eisenhower got acquainted at the new Army Armor School where the two would completely disassemble purchased tanks to study their operating systems then put those back together to determine the difficulty of their repair in the field. The US Army didn't have much money after WW1 so used J. Walter Christie to build prototypes of their designs since they used his services earlier which earned him $100,000. There's plenty of online information about J. Walter Christie.
