Saab has successfully completed the mid-life upgrade and modernisation of the Swedish Navy’s Gävle-class corvette, HMS Gävle.

The corvette was handed over to the Swedish Navy’s Fourth Naval Warfare Flotilla based at the Berga Naval Base in Sweden on 4 May.

The Fourth Naval Warfare Flotilla operates two Gävle-class corvettes HMS Gävle and HMS Sundsvall.

Swedish Navy 4th Flotilla chief Jon Wikingsson said: “The Flotilla welcomes HMS Gävle and her crew back to service.

“The ship will now be able to contribute to the navy’s ongoing maritime surveillance tasks. The ship and crew and will play an important part in the Navy’s active defence.”

The upgrade programme involved installation of several new systems to enhance and strengthen the Swedish Navy’s maritime combat capabilities under water and other fields.

Work under the contract to upgrade the corvette was performed at Saab’s shipyard in Karlskrona, Järfälla, Sweden.

Swedish Defence Materiel Administration (FMV) HMS Gävle mid-life upgrade project manager Johan Edelsvärd said: “It is a do over and modernisation of everything on board: She will have the same hull, but more or less all the systems on the inside are new.”

In 2017, Saab received a contract from FMV to modify and upgrade two corvettes, HMS Gävle and HMS Sundsvall.

Built between 1990 to 1993, the Swedish Navy initially had four Gothenburg-class corvettes in service, including HMS Gothenburg, Gävle, Kalmar and Sundsvall.

Later in 2007, Gothenburg and Kalmar were decommissioned.

Once the modernisation works on the remaining two corvettes, Gävle and Sundvall, are complete the vessels will operate as the Gävle-class corvettes.

The second corvette HMS Sundsvall is currently receiving the same modifications and upgrades at the company’s shipyard. Delivery of Sundsvall is expected later this year.
