Hello everyone, so, I guess you’ve already heard the news, FV215b is considered to be replaced by the Chieftain, at least that’s how Storm wrote it yesterday. However, this info (or speculations about it) is much older. The first time I heard about the plan to put the Chieftain in some form on tier 10 was as early as December 2012. I was on a meeting of the Czech community and Tuccy (back then still just a community organizer or whatever the title was) was talking about the changes to the trees. I took notes in my cellphone of what he was saying (I still have them, he for example mentioned the second French line, little did we know…) and one of the things he said is that the Chieftain would become the British tier 10 heavy tank. The next day, I wrote it on the forums (back then, there was no FTR) and the post got immediately deleted (this was one of the impulses that convinced me I need a platform of my own, so Wargaming can’t come and purge inconvenient info by the way). Next mention about it was from February 2013 and the result was “yea, we thought about that, not in immediate future” – and that was it. I wrote the above for you to understand that the idea is actually very old and that the Chieftain at some point “fell into the same vaporware hole” as the Sturmtiger, which sort of hints at the fact that implementing the Chieftain is problematic. But, Storm mentioned that the change might come around the end of this year, so hopefully that’s settled. Which Chieftain? So, now that this is decided, the real question is – which Chieftain will we see in the game? Originally I thought that there might be like three or four variants to pick from, including the mockups. I was wrong – there are like fifteen (maybe more) various prototypes and proposals, including the pre-production version. The most likely candidate I would say is the “P6″ prototype, that was mentioned in the past in connection with World of Tanks, simply because it stands physically in Bovington and Wargaming has access to it. This prototype was saved by Bovington from scrapping in 2011 and you can read about it here. This however is by no means the only option. The pre-production Mk.1 was also mentioned as a potential candidate, along with Mk.2 (the first one to see service en masse if I remember correctly) For example, one of the distinctive Chieftains is the “pike nose” Chieftain mock-up (there are proposed characteristics available for it, found in the Swedish documents). This pike nose variant for example weighed 45,3 tons, was proposed with a 700hp Leyland L60 engine with the maximum speed of 41 km/h. The gun is a “120mm L/55 gyrostabilized cannon”, but we’ll get to that. Anyway, there are options. These data come from the Swedish reports, found on the Chieftain development in Swedish archives. Characteristics Now, to understand what the problem with the Chieftain in World of Tanks is, you have to realize that the vehicle is still fairly new. Relatively of course. The production vehicles are from mid 60′s, the various early concepts and such are from 1960 or so onwards. The vehicle also fired shots in anger and some technologies from it are still secret, so it’s not like you can just get all the data on it on the internet. A good example of this is the tank armor. If you open western books on the Chieftain (for example “Chieftain” by Rob Griffin), the layout is roughly described, but the exact thicknesses of armor of schematics? Nope. I asked around, even at Wargaming and the only “published” armor schematic seems to be from a Russian source (for the Mk.1 variant): Alternatively, it’s possible to tap yet again into Swedish archives – this one is for the 1961 sloped nose prototype (courtesy of sp15 from US forums), such a schematic exists for the pike nose prototype as well. Third source of accurate info is the real life measurement of course. I can tell you straight away that that already happened. Xlucine did in fact measure the P6 prototype armor thickness for Wargaming with an ultrasound device. I am not at liberty to tell you what exactly were the results without his permission, but I think I can disclose two things: - the armor of the vehicle was worse than expected and by no means it’s as OP as everyone thinks - some parts are practically impossible to measure even for a person skilled with the ultrasound (Xlucine is skilled, but the entire process is actually quite complicated, it’s not like you just press a button), at least without some… more invasive measures (obviously out of question). The same thing applies for the Action X turret by the way – Xlucine did measure it as well, some parts were not measurable, some parts were… disappointing, overall it’s not exactly an option for tier 10 medium, I am fairly certain it won’t happen. Anyway, back to Chieftain. The engines are the variants of the Leyland L60 multifuel engine, tuned to various horsepower, if I recall correctly, the 585 horsepower variant was the earliest with the 750 horsepower variant the latest, there was also a a 650 and 700hp variant. It’s hard to say which one will be picked for the ingame vehicle, depends on the type of course, I’d go with the 650hp variant but that really depends on Wargaming (the Mk.4A 650hp engine was used in Mk.1, 2 and 3 Chieftains). The maximum speed of the early Chieftains according to the AFV handbook was only 40,2 km/h (with the vehicle weighing 50 tons or so, not bad). Third element of the tank is the firepower – as you can imagine, the firepower of the 120mm L11 is brutal. Firing APDS, HESH and HE rounds, its performance in the game will most likely be heavily rebalanced (as in nerfed) compared to its real life performance. Luckily, the gun has a very nice depression on the Chieftain (-10/+20). In case you are wondering about the 120mm gun performance, there is a memorandum from 1955, mentioning the defeat of plates of following thickness: APDS – 140mm (60 degrees, 2000 yards), HESH – 150mm (60 degrees, 2000 yards). In World of Tanks So, what do you get if you put the elements written above together? Well… hard to say. What I think we will get is basically a lighter and overall less armored (even though some spots are crazy thick) version of the T110 with a more powerful gun, Continue reading →
