Object 278 [USSR, Tier X Heavy Tank, 3-shell reverse autoreloader system]
Get ready for the launch of the Assembly Shop on February 12. The main star of the event is the Soviet Tier X breakthrough heavy tank Object 278, and below is an overview of what makes it special.
From February 12 at 20:00 MSK to February 18 at 23:59 MSK, the Assembly Shop introduces a new Tier X heavy tank, Object 278.
This event is all about resources and speed. Only 45,000 vehicles will enter the battlefield with the numbered 3D style “Borov”, and one of them could be yours.
Assembly rules and availability:
The number of vehicles is strictly limited. A total of 45,000 tanks are available for assembly with the numbered 3D style “Borov”, plus an additional 100,000 vehicles in the standard configuration. You will have six days to obtain Object 278 in its standard version. The tank with the numbered style, however, is a matter of minutes. Whoever is faster gets the number. Numbers are assigned sequentially from lowest to highest, and the Assembly Shop may close early if all vehicles are assembled. Prepare in advance, as there will be no second chance. To calculate which resources and in what quantities are best to invest, you can use the official calculator at https://tanki.su/ru/kb-feb-2026/.

I hope this will not be the assembly tank for the EU server as well… Not another Soviet tier 10 heavy…
we have the T-13 in supertest lmfao
i want this for EU
I want this as the T11 for the Obj 277 but without the autoreloader.
Please could we have a NON Russian tank as there are some of us who are fed up with the d**n things!
there are British, American, French ,Italian,Polish , Czechoslovak, Italian,German,Chinese,Japanese, and Swedish tanks that could be created, why not one of them??
don’t act like you have resources….for next 4 assemblies in 2026 😀
You American spy anyway!
Reverse auto reloaders are overpowered, they need a dpm nerf even when using the last shell compared to standard single shots,,but you never see the balancing so it just ends up being much more powerful than single shots of similar caliber..
145000 tanks released…? Crazy!
If you want to survive the narrow gaps in space waves, you absolutely need to practice the ‘Micro-tapping’ technique.
