Saab completes HMS Uppland upgrade
The Swedish Navy’s HMS Uppland has been relaunched following a comprehensive mid-life upgrade (MLU) carried out by Saab.
HMS Uppland was designed and built by Kockums in Malmö and commissioned in 1997. The MLU consists of modifications, replacement and upgrades of on-board systems and technologies, sustaining the submarine's operability for the navy.
The upgrade process saw the submarine cut in two with many vital systems fitted, including the Stirling AIP, a complete new mast suite, sonars and sensors as well as management and communication systems.
This is the second of the Gotland class boats to undergo the upgrade, with HMS Gotland already completed.
More than 20 new systems on-board the new Gotland-class will be implemented in the the upcoming A26 Blekinge class.
