Saab Delivers Second Upgraded Gotland-class Submarine to Swedish Navy

Saab has delivered HMS Uppland, the second submarine of Gotland-class to the Swedish Defence Materiel Administration (FMV) after a Mid-life upgrade.

aking all necessary measures to ensure the submarine's operational availability, the upgrade includes new sensors and navigation systems, giving the vessel enhanced capabilities. The delivery of HMS Uppland was conducted on December 16 at a ceremony in Karlskrona, Sweden.

HMS Uppland has had 50 new systems installed or modified, of which 20 are new systems that in the future will be used in the next generation of submarines, the Blekinge-class. This means, for example, new possibilities to analyse the boat’s surroundings with a so called Optronic Mast, replacing the traditional periscope and associated management system.

The Gotland-class submarines were built in 1990-1997. The submarine class consists of three submarines, all which have gone through minor modifications during the first part of their lifetime. HMS Gotland was the first boat to go through a Mid-life Upgrade. The submarine was split into two parts to be able to carry out larger changes.
