The NV-3 (Nárrodat Vovdna 3) is a main battle tank produced by Lappish arms manufacturer Ruoigu and is in service with the Lappland Home Guard as their main battle tank. The name of the tank translates to battle wagon, designated as the NV-3 for being the third tank concept produced in Lappland, despite the previous projects having been abandoned. The NV-3 is the first turretless main battle tank and adjusts its gun elevation by adjusting the hull suspension. The NV-3 is the only main battle tank currently in use by Lapplands armed forces. The hull of the NV-3 was also used for the HV-1 self-rpropelled Howitzer, also in service by the Lappland Home Guard

Development

Following Lapplands independence from Trinovantum, the Lappland Parliament began efforts to build up their armed forces, and began searching for a main battle tank. Ruoigu began work on their first tank designs in (year), with the first two designs being traditional turreted tanks. The Home Guard determined these designs to be too vulnerable to incoming fire and requested a tank with a reduced visual signature and better crew protection. After examining recorded tank losses in the Omandan Continental War, Ruoigu began working on designs that eliminated the need for a turret as many tank losses involved hits to the turret ring or the turret itself.

An early version of the NV-3 had the gun in a small turret on top of the tank with the crew housed entirely within the hull with a concept model being constructed. The final design fixed the gun within the hull as the system for adjusting the hull to elevate the gun was developed.
