The Styrsö class is a series of mine countermeasures vessels in service with the Swedish Navy built from glass fibre. Among its intended missions are naval mine detection, mine hunting and patrolling. The ships are named after islands from four different archipelagos of Sweden. In 2004 HSwMS Spårö and HSwMS Sturkö were modernised, pulling out some of their capability for traditional mine clearance in favour of extended human dive support, the modified vessels are occasionally called Spårö class.
Description
The ships are equipped for acoustic, magnetic and mechanical mine clearance. There is also an underwater vehicle type Uven and a
remotely-operated vehicles
(ROVs) of the type Uven and are prepared for the next generation of ROVs called ROV S.
The class is built exclusively with civilian technology, so-called (COTS), everything from diesel engines to the computers on board have been bought from the civilian market. This method simplifies the procedure of upgrading the system, it is also very cost-effective eliminating the need to develop new expensive military systems. The ships have a completely integrated command and navigation system with computer communication and projection of charts in a 3D environment.
History
The class consists of four ships that were built from 1996 to 1997. They are an important addition to the Swedish mine clearance ability. In 2004 HSwMS Spårö and HSwMS Sturkö were modernised, pulling out some of their capability for traditional mine clearance in favour of extended human dive support, the modified vessels are occasionally called Spårö class.
