Landsort class mine countermeasures vessel


Landsort class mine countermeasures vessel

The "Landsort" class mine countermeasures vessel is built by Swedish shipbuilding company, Kockums (formerly Karlskronavarvet) for the Swedish Navy and the Republic of Singapore Navy (RSN).

Design

As a mine countermeasure vessel, the hull is made out of glass-reinforced plastic in order to lower acoustic and magnetic signatures, as well as provide improved shock resistance to underwater explosions.

The "Landsort" class is equipped for mine sweeping with both conventional mechanical sweeping gear as well as electric and acoustic sweep systems. Mine hunting capability is provided by remotely operated vehicles (ROVs) from Saab Underwater Systems, such as the Double Eagle.

"Koster" Class

In December 2004, the Swedish Navy awarded Kockums a contract for the mid-life upgrade for five of the "Landsort" class (excluding HSWMS "Landsort" and HSWMS "Arholma"). The upgrade includes a new mine countermeasures (MCM) system, adaptations for interntational operations as well as a new air defence systems involving moving and modification of the Arte 726 from the "Kaparen" class fast patrol boats.

The upgraded vessels will be renamed as the "Koster" class, as the first vessel to be upgraded is HSwMS "Koster" (formerly the third ship in the "Landsort" class). [cite web | title=42.

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 (IMCMS-S). The systems will be commissioned into operational service between 2008 and 2009.

It comprises a Atlas MCM Tactical Command and Control system, a broadband Atlas HMS-12M hull-mounted sonar and a Atlas mine identification and disposal system (MIDS) 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.
