BAE Systems has secured a contract worth around Skr600m ($62m) from the Swedish Defence Materiel Administration (FMV) to provide additional Bonus precision-guided munitions to the Swedish Armed Forces.

The contract indicates a continuing partnership between BAE Systems Bofors and the Swedish military.

The Bonus munition is designed to extend the reach of 155mm cannon artillery, enabling precise destruction of enemy vehicles such as armoured personnel carriers, infantry vehicles, self-propelled guns, and main battle tanks.

BAE Systems Bofors ammunition sales director said: “This contract for additional Bonus projectiles to Sweden, the third since 2017, reinforces our long-standing partnership with the Swedish Armed Forces.

“We are committed to delivering a trusted solution that strengthens their indirect fire capability and keeps their warfighters safe.”

The development of Bonus is a collaborative effort with Nexter Systems, and it has been adopted by multiple countries, including Finland, France, Norway, Sweden, and the US.

This munition operates on a fire-and-forget principle and is loaded like standard artillery shells. Upon firing from any 155mm artillery system, the Bonus shell releases two independently targeting submunitions that scan for targets across an area of up to 32,000m².

Incorporating a base-bleed mechanism, Bonus can achieve distances up to 35km when fired from a Nato L52 gun. Each submunition autonomously locates and engages a separate target, enhancing the effectiveness of each round compared to conventional ammunition by delivering two precision-guided munitions from a single shell, explains the company.

This capability positions Bonus as a suitable option for integration with advanced artillery systems, including BAE Systems’ Archer.

In March 2025, FMV received consent to move ahead with the procurement of 18 Archer artillery systems from BAE Systems Bofors.

The Archer systems are being acquired as part of Sweden’s 18th support package to Ukraine.

FMV is also set to secure five Arthur counter-battery radar systems from Saab. The systems will improve Ukraine’s ability to detect and respond to enemy artillery.
