Chrysler's Heavy Tank "K".

Author: Priory_of_Sion

In May of 1946, Chrysler presented a heavy tank to the War Department Equipment Board. Chrysler's vehicle arose from postwar requirements for American heavies that were spawned by the fear of the IS-3. The Chrysler vehicle was called the Chrysler K Tank(no relation to the K Cars). Oddly, The K Tank featured some unorthodox design features. Most notably is the rear turret design. Other oddities about the K Tank is the 4 .30 caliber MG pods(fired remotely like the guns on the B29 bomber), the unique suspension, the 1200 hp engine, and the location of the crew all being within the turret much like the MBT 70.

With an estimated weight of 60 tons the K Tank was a relatively large and well protected vehicle. The frontal hull armor of the K Tank is approximately 205 mm(178 mm at 30 deg) thick without normalization. The side armor being near 76 mm thick, with proper angling the K Tank could be an effective side scraping vehicle. The turret armor is very thick in the front like most American vehicles even without the mantlet. The rear area of the turret is where ~100 rounds of the main gun ammo would be stored. By the way, the main gun is the 105 mm T5E1(which is going to be a subject sooner or later itself), however the rear turret arrangement really hampers the depression values(-5 degrees would be lucky to get out of it). 

The 1200 hp engine would give this behemoth ~20 hp/t which is more/less the same as the E-50. However the 60 ton weight mark is most likely an underestimate. The final drive is located in the front which could pose some fire issues. 

It is noteworthy to mention that Chrysler reused the K Tank name in the late 60s when they were asked to create the next generation of M60s. The K Tank used technology from the MBT 70, but the 2nd K Tank was also never adopted and faded into oblivion. 

In WoT the K Tank would find itself a good spot as a tier 8 premium in my opinion. The possibility of an alternate US Heavy line also opens the opportunity to have the K Tank become a researchable tier 8 or even a tier 9 armed with a more powerful 120 mm gun. I haven't seen WG ever talk about this design though so we might never see this vehicle in WoT.

"Buff my tank!" - VK 30.01 (P)

By Zarax

Hello and welcome to "Buff my tank!"

The "Buff my tank!" articles are meant as an historical way to look at some tanks considered underpowered in game and ways to improve their combat abilities discussed by the original german engineers.
Beware that while being sometimes ironic in tone, the article treats about both costs and benefits of every choice and it most likely will never be listened by WG as suggestion.

Today we will tackle on a somewhat unpopular tank, the VK 30.01 (P).

Historically, the VK 30.01(P) was the test bed for many of the innovations that went into many of Dr. Porsche's designs , sharing both their strengths and weaknesses.
Although it never left the prototype stage, it's direct evolution was the Tiger (P) which saw limited production and battle in one example, with most being reconverted in the Ferdinand/Elefant.

In WOT it's seen as a middle ground tank between the VK 36.01 (H) and the other, more agile lines.
In terms of game-play it's indeed pretty average and there have been many buff requests in the past, however let's look at what german engineers imagined for this tank, using "Panzerkampfwagen VI P (Sd.Kfz.181) The history of the Porsche Typ 100 and 101 also known as the Leopard and Tiger" as historical source:


As only one prototype was ever built and its development was superseded by Tiger (P) no plans were ever made to up-armor the VK 30.01 (P).
However, given that its successor was not a radically different tank and itself was up-armored with bolt-on plates, it wouldn't be impossible to imagine the same treatment, possibly with an easy to produce 30 or 50mm add-on plate.


The prototype twin 210 HP engines were sufficient to obtain a top speed of 60 kilometers per hour on optimal terrain, although with very high fuel consumption.
Again, as Tiger (P) mounted basically an uprated version of the 30.01 engines, upgrading to twin 310 HP for a very respectable power to weight ratio of  17/18 HP/ton.


First of all, WOT stock 75mm L/48 cannon is an historical mistake and introduce purely to prolong the grind on the tank and "encourage" the player to use gold for free XP:

Krupp showed some extremely interesting proposals for the VK 30.01 (P).
The standard issue cannon was supposed to be the 8.8cm K.W.K. L/56 just like Henschel's Tiger, but more options were discussed:

A proposal for a 10.5 cm K.W.K. L/47 was competed on April 10, which would likely have been a redesigned 105mm L/52 for tank use with slightly lower penetration, but the most interesting one was the proposal for an higher velocity version of the 8.8cm K.W.K. L/56 on April 18 using fatter shells.

Both options would have given more than outstanding firepower, especially considering how deadly the FLAK 36 already proved to be on the battlefield but unfortunately both were discarded as one used a non-standard army caliber (not that this stopped Krupp from trying it again later on) and the other would likely have depended on the use of always scarce Tungsten due to the shell shatter effect at such high velocities.

It is also likely that both options would have meant reduced ammo capacity and in case for the 105mm also lower rate of fire, especially if the two piece ammunition was retained.
Mobility would also be adversely affected by an heavier gun, something that made the normally adventurous Dr. Porsche refuse the idea of an 88mm L/71 on Tiger (P) later on.


In WOT terms the tank is fairly balanced, although personally I wouldn't mind a little more agility.
Historically the tank design was rejected because it was too complex to maintain for the battlefield conditions, used precious copper and was seen as generally unreliable, with the electric motors often developing a tendency to overheat, although the VK 30.01 (P) prototype served as an excellent test bed for such an advanced drive train for its time.

Its direct evolution, the VK 45.01 (P) was also marred by the same faults and rejected because of them and thus lost to the more standard Henschel counterpart.
Still, as many other Porsche designs it sprung many innovations and although most of them never reached production stage it is still a monument to tank engineering ingenuity.

All in all, I'd say Balanced for WOT, most upgrades are already in place and the ones missing would be more fitting for one tier higher or a tank destroyer.
