HMS Gotland is an attack submarine of the Swedish Navy. It is the first of the Gotland class, which is the first operational submarine class in the world to use air-independent propulsion (AIP).
She was built by Kockums, launched in 1995 and subsequently commissioned in 1996. The AIP units use liquid oxygen with diesel as the propellant.
[edit] Lease to the United States Navy
In 2004, the Swedish government received a request from the United States of America to lease HMS 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 March 21, 2005.[1][2]
HMS Gotland was loaded onboard the Norwegian semi-submersible heavy-lift ship, MV Eide Transporter, on May 10, 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 June 27, 2005.[3][4][5] After a couple weeks of getting accustomed to the new environment, the exercises with United States 3rd Fleet began on July 18, 2005.[6] The lease was extended for another 12 months in 2006.[7][8][9]
HMS Gotland managed to penetrate the massive defensive measures of a carrier battle group undetected and snap several pictures of the USS Ronald Reagan during a wargaming exercise in the Pacific Ocean, 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, HMS Gotland departed San Diego for Sweden.[13]
