MCMV 47 and MCMV 52

Mine Counter Measure Vessels (MCMV)

Saab has decades of experience in Mine Countermeasure Vessels (MCMVs) and associated systems. MCMV 47 of the Swedish Landsort and Koster-class, as well as the Singaporean Bedok class, are well-proven around the world.

Key features

A multi-purpose vessel equipped for mine hunting and mechanical minesweeping, and can operate the remotely controlled, autonomous Self-propelled Acoustic-Magnetic (SAM) minesweeping system.

Efficient MCM Vessels

The naval mine has proved a useful and cost-effective weapon since it was developed in the 19th century. Representing a significant threat to even the most sophisticated warships, the naval mine has gradually evolved and incorporates a range of smart detonators.

A wide variety of mine types are deployed today, and many of these are highly advanced. This has led to new demands for revolutionary and enhanced Mine Countermeasures (MCM) systems.

Reliable with multi-purpose capabilities

Saab Kockums has decades of experience in Mine Countermeasures Vessels (MCMVs) and associated systems. MCMV 47 of the Swedish Landsort and Koster-class, as well as the Singaporean Bedok class, are well-proven around the world.

The role of the Swedish Koster-class is primarily mine hunting. Its secondary role is minesweeping. Unlike single-role mine hunters, MCMV 47 Koster-class (originally Landsort-class) was conceived as a multi-purpose vessel, able to perform various mine warfare tasks and also to engage in anti-submarine warfare (ASW).

The Koster-class design is well-proven and extensively verified, with operational experience gained from a multitude of MCM operations, including live mines and underwater explosives. Seven ships of this class have been delivered to the Royal Swedish Navy, and a further four to the Republic of Singapore Navy.

MCMV 52 enhanced Koster-class

MCMV 52 enhanced Koster-class is based on the existing and well-proven MCMV 47 Koster-class, which is currently in operation with the Royal Swedish Navy. This enhanced version
has been engineered to meet more demanding customer requirements.

The main enhancements on MCMV 52 Koster-class include extending the Length Overall (LOA) by 5 m to 52.5 m. This creates more space for crew and systems, and improves sea-keeping and ensures a growth margin for the future. MCMV 52 Koster-class will keep the basic hull lines from the proven MCMV 47 Koster-class.

Designed for a variety of mine warfare missions

Due to the wide variety of mine warfare missions, many specific requirements have been taken into account in the design of the MCMV 47 Koster-class and MCMV 52 enchanced Koster-class.

Some of these requirements are:

  • High resistance to underwater explosion shocks
  • Low signatures
  • Excellent manoeuvrability
  • Full nuclear, biological and chemical (NBC) protection
  • Electromagnetic compatibility (EMC)
  • Spacious accommodation and ample supplies for extended missions
