HSwMS Uppland, the Swedish Royal Navy’s second Gotland-class submarine, was relaunched at Saab’s Karlskrona shipyard on Wednesday, June 19, following a comprehensive mid-life upgrade programme.

The upgrade saw the submarine lengthened by two metres to accommodate an improved air independent propulsion (AIP) system. It has also been fitted with a complete new mast suite as well as enhanced sonars, sensors, and management and communication systems.

Uppland‘s relaunching comes 12 months after sister ship HSwMS Gotland finished undergoing its own mid-life upgrade at Saab.
