HSwMS Gotland (Gtd) is an attack submarine of the Swedish Navy. It was the first ship of the Gotland-class, which was the first operational submarine class in the world to use air-independent propulsion in the form of Stirling engines which use liquid oxygen and diesel as the propellant.

It was built by Kockums, launched in 1995 and subsequently commissioned in 1996.

Lease to the United States Navy[edit]

In 2004, the Swedish government received a request from the United States of America to lease Gotland – Swedish-flagged, commanded and manned, for a duration one year for use in anti-submarine warfare exercises. The Swedish government granted this request in October 2004, with both navies signing a memorandum of understanding on 21 March 2005.[1][2]

Gotland was loaded on board the Norwegian semi-submersible heavy-lift ship, MV Eide Transporter, on 10 May 2005, for a month-long voyage over the Atlantic Ocean and through the Panama Canal to Naval Base Point Loma in San Diego, California, where it arrived on 27 June 2005.[3][4][5] After a couple weeks of getting accustomed to the new environment, the exercises with United States 3rd Fleet began on 18 July 2005.[6] The lease was extended for another 12 months in 2006.[7][8][9]

Gotland managed to penetrate the defensive measures of Carrier Strike Group Seven undetected and snap several pictures of USS Ronald Reagan during the December pre-deployment Joint Task Force Exercise 06-2 (JTFEX 06-2) in the Pacific Ocean (probably in the California Operating Areas), effectively "sinking" the aircraft carrier.[10] The exercise was conducted to evaluate the effectiveness of the US Fleet against modern diesel-electric submarines, which some have noted as severely lacking.[11][12]

In July 2007, Gotland departed San Diego for Sweden.[13]

Raid against Kockum[edit]

Early morning on 8 April 2014 the Swedish Defence Materiel Administration, known as FMV, with the help of the Swedish army raided the premises of German defense giant ThyssenKrupp Marine Systems. The goal of the mission was to confiscate material belonging to the Swedish state, especially hardware relating to the Stirling engines used in HSwMS Gotland. Although the raid was performed by armed military forces it was not violent. After Kockums employees locked the gates blocking FMV's exit with the confiscated material, a long drawn-out negotiation ensued. A compromise was finally struck in which the hardware was to be stored at a shared secure area until further notice. Since FMV was only interested in the hardware rather than the blueprints, the show of force was more likely part of a long political confrontation between the State of Sweden and the owners of Kockums, rather than an attempt at discouraging espionage.[14][15]
