The contract also includes options for FMV to order measures regarding the remaining three ships in the Koster-class. The total value of the options are SEK 270 million.
The contract with FMV means that Saab will carry out life extensions of two Koster-class mine countermeasures ships. The modernisation involves an exchange of systems for life extension and enhanced capabilities to ensure continued operability.
The program includes, among other things, a new navigation radar installation and improved capabilities linked to combat systems and surface sensors.
Mine countermeasures ships' main duties are naval mine clearance, submarine hunting, and maritime surveillance. When engaged in anti-submarine warfare, the ships can for example use mines, depth charges, and grenades.
Originally, the mine countermeasures ships were designated as the Landsort-class, but as five of the ships went through mid-life upgrades in 2009 an onwards, the class was renamed the Koster-class. At the same time, the ships were equipped with increased capabilities such as, for example, remotely controlled underwater vehicles.
The MCMVs have a length of 47.5 meters, a beam of 9.6 meters, and a displacement of 360 tons. The ships of the Koster class can reach a top speed of 15 knots.
The Swedish vessels are armed with Bofors 40 mm gun and two Ksp 58 machine guns, mines, and depth charges. They can carry a complement of 28 sailors.
