The Sisu GTP is a Finnish-made four-wheeled, modular mine-resistant ambush protected armoured personnel carrier (APC) designed and built by Sisu Auto, although the chassis and the powertrain is based on the Mercedes-Benz Unimog.[4] The first version was produced in 2018.[5]

In June 2020, the Finnish Defence Forces ordered six vehicles for testing.[6] In December 2022, the Finnish Defence Forces placed an order for an additional 25 vehicles that would replace RG-32M in Finnish service.[7]

Design

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

It uses Texelis T700 axles with independent suspensions.[8][9]

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.[10]

Failed bids

 Latvia
Sisu GTP was evaluated against AM General HMMWV, Otokar Cobra and Paramount Marauder in 2018[20] and selected as winner in a tender to supply armored vehicles for Latvian armed forces.[21] The deal, worth about 200 million euros, was canceled in 2019 after AM General and Paramount Group complained about the procurement procedure.[22]
