The Sisu GTP is a Finnish-made four-wheeled, modular mine-resistant ambush protected infantry mobility vehicle (IMV) designed and built by Sisu Auto, although the chassis and the powertrain is based on the Mercedes-Benz Unimog. The first version was produced in 2018.

In June 2020, the Finnish Defence Forces ordered six vehicles for testing. In December 2022, the Finnish Defence Forces placed an order for an additional 25 vehicles that would replace RG-32M in Finnish service.

Design

The vehicle has a chassis base with mission modules that can be changed.

It uses Texelis T700 axles with independent suspensions.

Framework agreement FISE

Through the framework agreement between Finland and Sweden for defence cooperation, over 260 vehicles are planned to be produced. It includes troop transport variants, air-defence, command and control, medical care, single cab transport variants and CBRN reconnaissance.

Failed bids

Latvia
Sisu GTP was evaluated against AM General HMMWV, Otokar Cobra and Paramount Marauder in 2018 and selected as winner in a tender to supply armored vehicles for Latvian armed forces. The deal, worth about 200 million euros, was canceled in 2019 after AM General and Paramount Group complained about the procurement procedure.
