Koster-class mine countermeasures vessel

The Koster-class is a series of mine countermeasures vessels in use by the Swedish Navy. It is one of two subclasses within the.

Overview

In December 2004, the Swedish Navy awarded Kockums a contract for the mid-life upgrade for five of the Landsort class. The upgrade includes a new mine countermeasures system, adaptations for international operations as well as a new air defence system involving moving and modification of the Arte 726 from the Kaparen class fast patrol boats. The first is expected to be completed in 2008. The upgraded vessels will be renamed as the Koster class, as the first vessel to be upgraded is HMS Koster.
On 31 January 2005 a contract exceeding €30 million was awarded to Atlas Elektronik for the upgrade of these five vessels with the Atlas Integrated MCM Systems. The systems will be commissioned into operational service between 2008 and 2009. The system combines minehunting, minesweeping, mine disposal, surveillance and communication with other naval forces. It comprises an Atlas MCM Tactical Command and Control system, a broadband Atlas HMS-12M hull-mounted sonar and an Atlas mine identification and disposal system Seafox. The IMCMS-S onboard also fully integrates sensors and effectors like the self-propelled variable depth sonar, underwater positioning system, navigation radar and sensors, conventional MIDS systems, and air defence system.
The vessels are also upgraded to have Link 16 capability.
