Maintenance and upgrade

In 2014 HNLMS ''Zeeleeuw'' was taken out of service after years of service by the Royal Netherlands Navy to perform maintenance and modernize its systems. During the upgrade program, the submarine was upgraded with modern systems. The ageing GIPSY combat system was replaced with the more modern Guardion combat system. Besides changing the software suite, hardware components were either replaced or upgraded with newer versions. The Medium Range Sonar (MRS) and Long Range Sonar (LRS) were replaced. A new sonar was added, the Mine and Obstacle Avoidance Sonar (MOAS). The consoles and screens in the command room were upgraded to more modern versions, while the navigation and attack periscopes went from being depended on analog sensors to digital sensors. This was done by replacing several masts. Lastly, the Mark 48 torpedoes were upgraded from mod 4 to the more recent mod 7.
