It was built by Kockums, launched in 1995, and subsequently commissioned in 1996.
In 2015, Sweden's Defense Material Administration (FMV) signed a contract with Saab Kockums which included a mid-life upgrade of two members of the Gotland class, Gotland and Halland, for SEK 2.1 billion. Gotland is expected to return to the FMV in late 2018 following a series of platform and combat systems upgrades.
