Mid-life upgrade[]

In 2020, HSwMS Uppland did undergo a mid-life upgrade, as her sister HSwMS Gotland after her. During the upgrade, a number of systems that will be used in the next generation submarines, the Blekinge-class (A26), was installed. More than 20 new systems on board the new Gotland-class was implemented, which contributes to their de-risking for the A26. This also offers training opportunities for the crew when they in the future deploy on board the A26.

The upgrade process entails many new systems, such as the Stirling AIP, a complete new mast suite, sonars and sensors as well as management and communication systems. In order to host all systems, the submarine has gained length to 62 m and another 200 tons in weight, to reach a displacement (surfaced) of 1580 tons.
