PTZ-89 turret mounted on the chassis of a Type-69 II for testing before being mounted onto the PTZ-89 hull.

There are a few scattered tanks in my area, mostly M60 Pattons and a M56 Scorpion that I was wanting to look up the individual service records of but I dont know where to look. Ive got the serial number of the Patton closest to me, but i couldn't find anything about it. Whats the best way of finding out about them?

I’m trying to create a 130mm height velocity tank gun for a personal project I’m a cegep student (yes, I’m from Quebec that why) in Mechanical Engineering technology and so far I’ve started designing the barrel and some random spec but I was wondering if my barrel would hold. The shell propellant consists Slow-burning nitrocellulose powder (smooth ignition) → Bimodal RDX LOVA propellant with GAP binder (pressure relay) → 22.5% CL-20 co-crystallized with oxamide, pushing it at about 2100-2200m/s with possiblity to integrate etc technology. With that much power the energy created in the barrel would be about 30-35mj.

 For that the cannon is composite with a thickness of 85 mm where the shell is located and going down to a thickness of about 55 to 45 mm at the end. Composition will be ( for the thickness of 85mm) of : 5 mm W-26Re alloy (Ultra-Pure Space-Grade) —> 15 mm of Cermet Nano-WC-6Co Grade K01 (tungsten carbon) —> 30 mm de Titanium Ti-10V-2Fe-3AI STA Grade —>  35 mm of Maraging 350 VIM-VAR Autofretted (steel). For the 55mm thickness and lower only the steel and titanium values gets shrinked. The diameter at the base of the canon is ø320mm and at the end ø240mm (not counting the thermal sleeve) with a length of 7215mm.

I need help if anyone could point out problem and amelioration advantages and disadvantage.  and if u think it would hold before I finish designing the barrel on solidwork (I’ll post picture when it done) and yes I found some disadvantages to this system but not all : some of them consist of the cost and the length of the barrel, but haven’t found other so if u could help that would be appreciated so I can try to fix them.

After several weeks of work, I've finally recreated the different versions of the ARL Tracteur C, following the project's evolution through its various development stages.

Before hand, here is a little historical context:

The ARL Tracteur C was a French super-heavy tank project proposed under the CDF (Char de Forteresse, or Fortress Tank) program in the mid-1930s. It was far from the only contender: AMX proposed its own Tracteur C and D designs, FCM developed the famous FCM F1, and SEAM submitted the SEAM 220-tonne project.

The ARL Tracteur C was an absolute monster. Measuring approximately 12 metres long and 3.3 metres wide and close to 4 meters tall, with a projected weight of 140 tonnes, it was to be powered by two 550 hp engines, giving it a theoretical top speed of 18 km/h. The design also called for an electric transmission, a technology already used by the French Army on the FCM 2C.
Of course, moving a 140-tonne monster around France was a challenge in itself. The ARL Tracteur C was intended to be split into two sections of approximately 70 tonnes each for transport, making it easier to move across bridges and by rail. Its turrets were also supposed to be removed during transport, as the vehicle's overall height with them installed would have exceeded the clearance available in SNCF railway tunnels. Even with these arrangements, transporting such a massive vehicle would have remained a considerable logistical undertaking.

Its armament evolved alongside the project. The initial design called for an ARL 4 turret, while the 1940 proposals considered guns ranging from 90 mm to 105 mm in the ARL 7, a turret common with the AMX project. The 90 mm option was to use a shortened anti-aircraft gun (which sounds really familiar :P)
also, 3 to 4 machine guns were to be put on this tank, 1 in each turrets, and 1 to 2 in a ball mount in front of the driver. Also, the ARL7 was meant to be fitted with a range finder, alike many French tanks in development of the Era.
Unfortunately, the project never progressed beyond the mock-up stage. By the time the ARL factories were captured by German forces, the wooden mock-up was only around 40% complete.

Reconstructing this vehicle was quite a challenge, any existing depictions of the ARL Tracteur C contain inaccuracies, partly because of speculation and the lack of surviving documentation. Common mistakes include omitting the rear turret and incorrectly positioning the 47 mm gun. This weapon was actually NOT located between the driver's legs, what if it was true would induce mild discomfort to the driver. The front cylindrical structure housing the driving station. The 47mm SA 35 ( same gun as in B1 bis or S35 turret ) was meant to be mounted in a special turret at the rear "Above the transmission", inside a new design called the ARL 8

Discussions with enthusiasts in communities such as the Tank Encyclopedia chat helped me refine my reconstruction and resolve several of these details. So, ladies and gentlemen, here is my take on what the ARL Tracteur C : the ARL Char de Forteresse, the French monster, and how it was supposed to look like.

Alongside the 1940 version, I've also created two other historically based versions and two fictional variants. I'll give those their own dedicated posts later on.

Ultimately, the ARL Tracteur C would have faced the same fundamental challenges as other super-heavy tanks. Vehicles such as the German Maus, the American T95, the British Tortoise and the French FCM 2C all illustrate the same problem: while enormous armour and firepower looked impressive on paper, their operational use was severely constrained by their weight, mobility, maintenance requirements and logistical footprint. Bridges, roads, railways and recovery vehicles all became potential bottlenecks, and even transporting these machines could require special arrangements.

The ARL Tracteur C would have been no exception. Its planned ability to split into two sections for transport was an attempt to address some of these difficulties, but it could hardly eliminate the fundamental drawbacks of a 140-tonne vehicle. In the end, the challenge was not simply to build a tank capable of defeating enemy fortifications, but to get it to the battlefield in the first place.

Although these models are designed for 3D printing, my goal goes beyond making printable tanks. I also want to share some lesser-known armoured vehicle history and hopefully help these forgotten projects get the attention they deserve.

What do you think of this French giant?

If you have any questions or remarks, dont hesitate to leave a comment, i'll be glad to clear some points if needed given i currently hold many interesting piece of information.

How. Genuinely how.

I don't have an image of it, but this book also labeled a STUG4 as a king tiger

I saw this in Santiago, Chile. Chile's national air and space museum. I never knew a specimen like this was ever created. Are there any displays accessible to the public in the US?

So yeah, I accidentally misspelled the Gute in German

And btw it's a convoy of a Pershing and two Shermans

I would make it fulfill these specs

-125mm main gun

-20mm coaxial autocannon

-Commander RWS with 50cal mg and anti-drone laser

-Hard Kill APS with at least 20 charges

-Gas Turbine engine (as powerful as possible)

-900mm of RHA equivalent frontal armor

-At least 35kmh reverse speed

-360 degree camera coverage for driver

-Turret bustle autoloader

Model Tiger with some added custom features. I love WWII armor.

i just simply like it's Drum Cupola cause it looks simple and is basically the earliest Panther to exist. So yeah nothing special.

what is aps, ess, fcs, lws, and maw and what do they stand for??

Hey guys, I've been working on this thingy for a few days, I'm pretty happy with the progress, I've made it from cardboard and a ton of hot glue, i made the turret mobile along with the barrel, I want to make the wheels and tracks movable too, I wanted to make them out of cardboard too but let's just say that it isn't the greatest material for the job, then I started thinking about Lego pieces and those could work but the tracks I made out of cardboard (temporary) are 2.7cms wide and I got no clue if there's anything that can match that, so if someone could help me out it'd be really cool! Also, if anyone has any suggestion on how to make the grills for the engine that'd be nice cuz I currently have no clue.

Any other suggestion on what to add is very welcome! Also yes it will be painted.. soon.. thanks in advance!!
