Sisu unveiled its GTT all-terrain vehicle (ATV) at the SecD-Day conference and exhibition held in Helsinki on 29–30 January 2025. The high-performance, multi-purpose platform is designed to operate in all geographical environments, including extreme climate conditions and the harshest Nordic terrain.

The Sisu GTT ATV programme combines the design and maturity of ST Engineering Land Systems' Bronco with the technologies and solutions of the Sisu GTP 4×4 offroad vehicle, which the Finnish company expects to provide security of supply through provision of design and engineering expertise, local manufacturing, and in-country life-cycle support.

Sisu said the modular vehicle is suitable for various operational roles and is available. Jyri Ahonen, Sisu Auto's vice-president, Defence, told Janes on 3 February, “Numerous different configurations within the vehicle's payload capacity would be possible. The twist lock interface can accommodate any 10 ft container-type system. [The] APC [armoured personnel carrier] cabin is [also] suitable for command, control, and communications use [and] medevac [medical evacuation].” In addition, the cargo platform configuration can accommodate any 10 ft container-type load up to a weight of 5 tonnes, such as a mortar module or any other mission-specific system, according to Sisu.

Asked if the Sisu GTT was for a specific Nordic requirement, Ahonen said, “Nordic defence forces have ageing ATVs in their inventories. Sisu GTT would be a very suitable replacement for these ageing fleets.”
