The KV-5 was one of many experimental projects out of the Kirov plant that were cancelled when the Wehrmacht attacked Leningrad. No prototype of the KV-5, a.k.a. "object 225" was ever built. However, it would have been classified as a super-heavy tank, thanks to its estimated weight of 100 tonnes. The tank was to be armed with the same 107mm ZiS-6 cannon as all the other super-heavy tank projects, along with no fewer than three machine guns (one coaxial, the other two in smaller turrets).
Ordering the small variant will give you a single tank.
Ordering the medium variant will give you two tanks.
Ordering the large variant will give you five tanks.
Too expensive? Want it in a different colour or slightly larger scale? I sell this exact same model
on my website.
