The modernization has been carried out at Saab’s shipyard in Karlskrona and is the largest change the ship has gone through during her lifetime. In parallel, her sister-ship HMS Sundsvall is going through the same modifications and will be delivered in 2022.

The modernization of HMS Gävle includes a number of new systems. The vessel will have, among other things, a new torpedo guidance system, a new all-purpose gun (57 mm. Mk3B), and a new towed array sonar that will be integrated into a completely new guidance support system.

She is also equipped with a modified reconnaissance radar with a built-in recognition system. The reconnaissance radar is a so-called 3D radar and it measures, in addition to bearing and distance, also the height of targets. Similar radars are also in service on the Visby-class corvettes.

HSwMS Gävle (K22) is a Swedish Navy Göteborg-class corvette, named after the Swedish city of Gävle. The ship was launched on 23 March 1990 at Karlskrona and entered naval service on 17 September 1990.
