Swedish Artillery Modernization: Archer 155 mm SPHs Enhanced
Overview of the Archer System Upgrade
The Swedish Defence Materiel Administration (FMV) has achieved a significant milestone by completing the upgrade of the last batch of Archer 155 mm wheeled self-propelled howitzers (SPHs). This upgrade, conducted by BAE Systems Bofors, was officially confirmed on October 30, 2025, marking a pivotal moment for Sweden’s artillery capabilities.
Key Features of the Upgrade
A total of 24 Archer 6×6 SPHs have been modernized to the Version C standard. The upgrade includes:
-
Chassis Transformation: The iconic Archer gun system has been adapted to the Rheinmetall MAN Military Vehicles (RMMV) HX2 8×8 platform, which is designed for superior operational mobility compared to the previous Volvo A30D 6×6 all-terrain articulated chassis.
-
Enhanced Command Support: This modernization effort introduced an upgraded command support system, facilitating better integration and command functionalities on the battlefield.
Recent Developments in Procurement
In a strategic move to bolster artillery capabilities, the FMV placed an order for 48 additional Archer systems based on the RMMV HX2 chassis as part of a USD 500 million contract signed in September 2023. This procurement reflects the Swedish government’s commitment to enhancing its military readiness amidst evolving security challenges.
Statements from Defence Leadership
Jonas Lotsne, head of the Army Materiel business area at FMV, emphasized the importance of this upgrade in a recent press statement. He noted, “The culmination of upgrades for all Archer systems to Version C represents a critical advancement for the Swedish Armed Forces’ artillery systems, resulting in enhanced operational effectiveness through modernization.”
Field Deployment and International Support Initiatives
October 2025 also witnessed the inaugural firing of rounds from the newly upgraded Archer systems on Sweden’s Boden southern firing range, demonstrating the immediate operational capabilities of the modernized artillery.
Notably, while the Swedish Army upgraded 24 of its original fleet of 48 Archer systems, 14 were transferred to the British Army in March 2023 as part of an interim artillery replacement initiative. Additionally, the Swedish government provided humanitarian support by sending eight Archer systems to Ukraine, reinforcing its role in international security collaborations.
In April 2025, the Swedish government further committed to supporting Ukraine through the procurement of 18 new Archer 155 mm SPHs from BAE Systems, integrating them into its 18th support package for the war-torn nation.
Conclusion
The enhancements made to the Archer 155 mm SPH signify a substantial leap forward for the Swedish Army, elevating its artillery capabilities and ensuring alignment with contemporary warfare requirements. The adoption of the RMMV HX2 chassis exemplifies the move toward more mobile and versatile artillery systems, which are essential in modern military operations, particularly in high-intensity conflict scenarios. As Sweden continues to invest in its defense infrastructure, these advancements not only fortify national security but also position the nation as a pivotal player in regional and global defense partnerships.
