Category:Russian and Soviet tanks
User:AKMask added category:Russian and Soviet tanks to this article, with the edit summary:


 * It's a development of a russian/soviet base, I believe the category helps with finding it. And the Ukraineian development is in the first sentence, so its not confusing

While I understand AKMask's justification for ease of finding Soviet-legacy AFVs, we haven't been using categories this way. If we did, for example, the following copies and derivatives of Soviet tanks would belong in this category or equivalent ones, and I don't think a single one is. Likewise, the Ukrainian BTR-94 also doesn't belong in category:Russian and Soviet armored personnel carriers. Categories are clearly used to group AFVs by country of origin or main country of employment (sometimes both).


 * China: Type 59 (T-54A clone), Type 62 (scaled-down T-54A clone), Type 69/79 (Type 59 derivative with T-62 features), Type 96 (Type 69 derivative with T-72 features), Type 99 (advanced T-72 copy),Type 63 (PT-76 derivative)
 * Croatia: M-84 (T-72 copy), M-95 Degman (M-84 derivative)
 * Iran: Zulfiqar MBT?, T-72Z Safir-74, Boragh (BMP copy)
 * Iraq: Lion of Babylon tank (T-72 copy)
 * Israel: IDF Achzarit APC on T-55 chassis, Shoet APC (APC based on BTR-152)
 * Pakistan: MBT 2000 ('Al Kalid', advanced T-72 copy), Al-Zarar MBT (advanced Type 59)
 * Poland: PT-91 (advanced T-72 copy), PT-94 (PT-91 derivative?)
 * Romania: TR-580 (T-54/55 derivative), TR-85 (advanced T-54/55 derivative)
 * Yugoslavia: BOV APC

To be clear: the original features distinguishing the T-84 model were developed in independent Ukraine after the Soviet Union no longer existed, during the process of delivering T-80UD tanks to Pakistan, in order to make production independent of supplies from the Russian Federation. The T-84 was first built in 1994. The original design was based on the earlier T-80UD, T-80, and T-64 tanks all designed and first built at the Malyshev Factory in Soviet Ukraine, although the current T-84 Oplot model is clearly not just an advanced T-80 but a fundamentally new tank. So, although the T-84 has a Soviet Ukrainian technical legacy, this model originates in independent Ukraine.

And Ukraine cannot be considered to have been part of Russia, at least since the collapse of the Russian Empire in 1917, so the T-84 is not by any stretch Russian.

I believe that that category:Russian and Soviet tanks should be split in two anyway, since there is no category for the Russian AFVs which are not Soviet ones, but the details of that are a separate question. —Michael Z. 2006-07-10 18:38 Z 


 * Well, Im not going to edit war over this, but would you mind listing this on the Wikiproject Military History talk for some further input? I may very well just be crazy here, and will most graciously concede that if it seems correct as is to those guys, but I'd like some people familiar with military development to weigh in :) - M ask [[Image:Flag_of_Alaska.svg|20 px]] 04:01, 11 July 2006 (UTC)


 * Sure—it would be good to re-examine that category. I left a note at Wikipedia talk:WikiProject Military history. —Michael Z. 2006-07-11 19:29 Z 


 * I don't really see a reason why this should be listed under Russian and Soviet tanks. The purpose of that category was to provide a means for people to be able to easily trace up/down categories and help link modern Russian vehicles to historical Soviet vehicles cleanly.  Basically to help them conform with the way we do it for American or German vehicles, tracing back to one parent (Category:American tanks etc.).  The parent isn't usually supposed to have any articles in it as it should go into one of the daughter categories for which major war-era's it was used in. Oberiko 21:02, 11 July 2006 (UTC)


 * That makes sense. But how to satisfy AKMask's concerns?  Category:Ukrainian armoured fighting vehicles does not belong under category:Russian and Soviet tanks.  Perhaps there should be another sub-category category:Soviet-legacy armoured fighting vehicles, but this starts to get complicated.  —Michael Z. 2006-07-11 21:14 Z 


 * Also, perhaps category:Russian Empire armoured fighting vehicles should be split off on its own. It would only contain the Tsar Tank and Vezdekhod, which have little relationship to Soviet/CIS tank design and production.  —Michael Z. 2006-07-11 21:19 Z 

Allright, I'm now satisfied that this doesn't belong in the Soviet/Russian cat... but there should be some country-specific category for it... Just seems kind of lost in its current categories. - M ask  22:06, 11 July 2006 (UTC)
 * And thats happened now. My concerns are addressed, thank you all :) - M ask [[Image:Flag_of_Alaska.svg|20 px]] 22:07, 11 July 2006 (UTC)

Specs
User:Deepak gupta added a fact template to the following statement, and questioned some of the specs in this article at user talk:Mzajac:


 * '' Its high-performance engine makes it one of the fastest existing MBTs in the world, with a power-to-weight ratio of about 25 horsepower per tonne (19 kW/t).

I'll try to address the issue here.

The T-84 is based on the T-80UD, a high-performance diesel-engined version of the gas turbine-powered T-80U.

Top speed: various sources publish top speeds for the T-84 of "65–70 km/h", "70 km/h", and "85 km/h". The manufacturer's site states 65-70 km/h and 26 hp/t for the latest in-service T-84 Oplot, 65 km/h and 25 hp/t for the prototype T-84-120 Yatagan.  These may or may not be recommended maximum speeds: Vasiliy Fofanov's page states the T-80U's "Max Road Speed: 70 km/h (governed)", so it's not unreasonable to assume that other CIS tanks have engine governors built in to keep the tank to a speed that's safe for control of the vehicle and/or prevents excessive wear or danger of catastrophic suspension breakage (the U.S. M1 is likewise governed).

Power-to-weight ratio: I can't find a definitive citation at the moment, but the whole idea of the T-80 was to have a very high-performance gas turbine engine, to increase mobility. Apparently it was successful, with the T-80U's 27 hp/t power-to-weight ratio, compared to the T-72's 18 to 20 hp/t, earning it the moniker flying tank. The gas turbine had all kinds of problems, most notably severe fuel consumption, which were seen as trade-offs for increased performance. The initial T-80 had an unprecedented 1,000 hp engine in a 46-tonne tank, the T-80U increased that to 1,250 hp. The Morozov Design Bureau in Ukraine created the more conventional 6TD 1,000 hp diesel engine for the T-80UD, and improved that to 1,250 in the T-84 tanks. By adopting the T-90, the Russians have abandoned further production of more gas turbines, but are catching up in diesel performance at ChTZ, replacing that tank's 840 hp diesel engine with a 1,000 hp engine in the T-90S, and apparently have demonstrated a 1,200 hp version.

There are also other newer tanks with comparable power-to-weight ratios (Leclerc, Type 99), both in the 55-tonne range with 1,500 hp power plants, and the M1 Abrams is up there, although it weighs well over 60 tonnes with the full modular armour package installed.

Please note that such statistics published anywhere are probably quoted from manufacturer's marketing materials. —Michael Z. 2006-07-24 21:14 Z 

modern tanks
Who's messing with the modern tanks thing at the bottom, why rearrange it? And if you feel like you need to please label your catigories accordingly. —The preceding unsigned comment was added by Counterstrike69 (talk • contribs) 03:39, 21 February 2007 (UTC).

Development of the T-84-120
There is blatantly contradictory and potentially incorrect information in the section titled Development of the T-84-120. The article claims that 120mm gun of T-84-120 can fire AT-11 Sniper missile designed for 125mm gun. The AT-11 Sniper article itself says the missile was designed for 125mm gun. Also, the source is very suspect and cites a user post on the War Thunder Forum — Preceding unsigned comment added by Baljeet931 (talk • contribs) 15:14, 24 April 2023 (UTC)

In service of the GAF
Does anyone have infos about how many tanks the GAF wants to buy in total or if they plan to replace their whole amount of T-72s with T-84s ? There is no info at all about GAF wanting to buy T-84s, other than an allegation by Konovaliuk, which was dismissed by Minister of Industrial Policy. Ceriy (talk) 05:58, 11 January 2010 (UTC)

The story of Georgia aquiring T-84s is most likely nothing else but hoax - TheMightyGeneral (talk) 14:26, 19 July 2012 (UTC)

Oplot
So, what does Oplot mean? A few sources state that it's Stronghold but I can't find anything definitive, and it doesn't seem that oplot translates solely and directly into stronghold. Official name, wan-fank, or what? -Ashley Pomeroy (talk) 18:27, 28 May 2011 (UTC)
 * It's official name. Oplot mean stronghold.--Юе Артеміс (talk) 06:19, 5 October 2012 (UTC)

Service during the East-Ukranian conflict
So far the only account claiming that the T-84 has seen service during the Ukrainian Crisis 2014- has been The Daily Beast. (http://www.thedailybeast.com/articles/2014/08/13/as-the-key-battle-looms-a-report-from-ukraine-s-front-lines.html) I find this controversial and propably its a misidentification. Most likely he has seen a T-64BV, which are seen in various footages from Mariupol, but a BM Bulat would be possible too.

Ukraine de facto can not produce tanks
10 tanks were delivered by beginning of 2016.[19][20]

For 5 years, all was done in less than 15. Order 49. Actually all T84 is cut from the corpses of T80, to build one of several pieces. And it confirms Google. http://vz.ru/world/2016/4/29/807986.html — Preceding unsigned comment added by 188.162.80.47 (talk) 15:50, 14 November 2016 (UTC)

T-84 'Oplot' Autoloader
Hey all, bit new to editing for wikipedia so I'm gonna leave this in talk for a bit but I wanted to make something clear. It's a misconception that the T-84 'Oplot' and its derivatives including the Oplot-M and Oplot-T feature a bustle mounted autoloader. The new Autoloader design was only ever present on the T-84-120 Yatagan prototype, as a ready rack separated from the crew via a blowout box was a requirement for NATO standardization, and this required a redesign of the autoloader. As for sourcing, there's an image on this website that clearly shows an Oplot-M turret with the conventional Carousel autoloader inherited from the T-80. (Use page translation here) http://btvt.info/1inservice/bm_oplot.htm http://btvt.info/1inservice/bm_oplot.files/mz2.JPG http://btvt.info/1inservice/bm_oplot.files/mz1.JPG. Furthermore, an official 3D rendering of the Oplot-M from UkroBoronProm shows a carousel autoloader during a transparent "look-through" of the tank (youtube link /zhPZOU_iS1E?t=63). Several official sources also claim a "ready rack" (read: how many rounds are stored in the autoloader) of 28 rounds of ammunition, identical to conventional T-80s. The Yatagan meanwhile only had a ready rack of 22. Given that that original claim in the article is unsourced, it seems clear to me that this was a case of misinformation, I believe it's a problem of miscommunication as the Oplot turret does feature a blowout ammo storage compartment in the turret bustle, in a similar concept to the T-90M, but this is not a change to the autoloader. http://btvt.info/1inservice/bm_oplot.files/image014.jpg http://btvt.info/1inservice/bm_oplot.files/bunker2.jpg BlowoutPanel (talk) 09:47, 16 September 2022 (UTC)
