Sweden secures more than 300 Sisu GTP 4×4 armored patrol vehicles for Nordic defence.

Sweden’s Defence Materiel Administration has activated an option in the joint Finnish-Swedish framework to acquire more than 300 additional Sisu GTP 4x4 protected vehicles, lifting the total backlog above 500 platforms for the two partners. Framed within the FISE cooperation, the move deepens Nordic interoperability and strengthens protected mobility across the Baltic region as both armies modernise for a harsher security environment.

The Swedish Defence Materiel Administration has confirmed a new joint order for Sisu GTP 4x4 protected vehicles together with the Finnish Defence Forces, building on the bilateral framework that underpins the FISE cooperation programme. According to programme information, the latest tranche covers more than 300 vehicles for the Swedish Army, with deliveries planned between 2026 and 2028 and supported by a gradual ramp-up at Sisu Auto’s Finnish production facilities. The order follows initial contracts signed in 2024, when the first GTPs began arriving in Sweden under the TGB24 designation, and adds to a combined backlog now reported at over 500 vehicles for both countries.

The expansion of this fleet results from a contractual option included in the initial framework agreement, allowing both countries to add further quantities without additional administrative delay and to maintain a consistent schedule. FMV points out that the first vehicles from the previous order have just been handed over to Swedish units, while the increase in Sisu Auto’s production capacity supports the rapid integration of this new tranche. The Finnish forces, which already operate the vehicle in several configurations, accompany this overall development with a regional standardisation approach that reduces logistics costs and simplifies maintenance. Sisu Auto reports that around one hundred and twenty vehicles have been delivered so far and that the company continues to execute successive orders for the two Nordic customers.

The Sisu GTP 4×4, designed as a high-mobility multirole vehicle, is defined by a modular architecture that allows chassis, protection, and payload to be adapted to distinct missions. The baseline version uses a 6.7-litre turbocharged diesel engine developing around 270 horsepower, coupled to an automatic transmission intended to maintain traction on soft ground. The vehicle provides ballistic protection for the cab that complies with Level 2 of the STANAG 4569 standard, combined with a V-shaped hull designed to mitigate the effects of mines and improvised explosive devices. Its payload capacity is close to two tonnes depending on configuration, while independent suspension provides high ground clearance and the ability to climb vertical obstacles of about 0.4 metre.

The current orders cover several specialised variants. Medical, CBRN, command, and air-defence versions complement the single-cab and double-cab configurations already in service. In the ground-based air-defence role, the possible integration of mast-mounted electro-optical sensors, combined with a tactical management terminal compatible with national command networks, illustrates the structural flexibility of the vehicle. The platform can also receive enhanced protection kits or remote weapon stations, which broaden the range of achievable effects without altering the main structure.

Operational use of the GTP is based on a combination of strategic mobility and tactical robustness. Its controlled weight allows air transport by A400M Atlas, which facilitates deployment in austere areas. Maneuver units benefit from an operating range of more than 700 kilometres, an important factor in Nordic environments where supply routes are often far apart and exposed to harsh weather conditions. The crew compartment, sized to accommodate a squad depending on the variant, is equipped with an uprated air-conditioning system and filtration equipment suitable for contaminated environments. Cross-country performance, supported by automatic traction control and ABS adjusted for unpaved surfaces, enables reconnaissance tasks, convoy security, and troop transport in areas with limited infrastructure. The potential integration of secured communication systems providing an interoperable tactical data link reinforces the vehicle’s consistency with the Swedish-Finnish command architecture.

The Nordic strategic context gives this acquisition a dimension that goes beyond the renewal of a military vehicle fleet. The FISE framework supports doctrinal convergence between the two armed forces, accelerated by changes in the European security environment since 2022. The ordered quantities strengthen a regional industrial base able to meet Swedish and Finnish requirements jointly, while preparing exports to another European country mentioned by Sisu Auto. The denser network of protected mobility in the Baltic area contributes to the defensive posture of the coastal states and supports commitments within Euro-Atlantic structures, in a context where interoperability, logistical resilience, and the reliability of supply chains are established as long-term strategic priorities.
