Mid-life upgrade

In 2020, HSwMS Uppland underwent a mid-life update. During the upgrade, a number of systems that will be used in the next generation submarines, the Blekinge-class (A26), were installed. More than 20 new systems on board the new Gotland-class was implemented, which contributes to their de-risking for the A26.^{[clarification needed]} This also offers training opportunities for the crew when they deploy the A26 in the future.

The upgrade process included many new systems, such as the Stirling AIP, a completely new mast suite, sonars and sensors as well as management and communication systems. In order to accommodate all systems, the submarine has extended to 62 m and gained another 200 tons in weight. In the process HSwMS Uppland reached a displacement (surfaced) of 1580 tons.
