The Näcken class submarines, also known as the A14 type, were built for the Swedish Navy in the late 1970s. The boats were authorised in 1972 and the programme was completed in 1980 . All boats were built by Kockums in Karlskrona. The boats had a teardrop hull and diving depth was 150 metres (490 ft).

By the early 2000s the class was decommissioned from the Swedish navy as a result of defence cuts in the year 2000 Defence White Paper.


HSwMS Näcken:

HSwMS Näcken (Näk) is the lead ship of her class of submarine for the Swedish Navy. She was launched at the Kockums shipyard in Malmö, Sweden, on 17 April 1978, and completed and commissioned into the Swedish Navy in April 1980.

Refit:
In November 1987, Näcken began a major refit at Kockums. This involved installing two closed circuit Tilsa Stirling diesel engines. This new diesel, the Stirling V4-275R, provides air-independent propulsion which allows the submarine to operate continuously underwater. However, in order to incorporate the new engine, the ship was lengthened by 8 metres (26 ft). The refit took until 6 September 1988. The endurance of the vessel, following refit, increased to 14 days. Näcken became the test bed for the technology which was used in the later Gotland class.

The ship had further modifications between 1993 and 1996. This comprised improved weapon control systems, automated torpedo tube loading and new sonar.

Transfer to Denmark:
Näcken was transferred to Denmark in 2001 as part of a deal for the design and construction of the Viking-class project. The boat was leased by Denmark with an option to buy in 2005. Before the transfer, Denmark had the communications systems aboard upgraded. The submarine was recommissioned as S-325 HDMS Kronborg on 17 August 2001 at Aalborg. Denmark had acquired Kronborg partly to keep a submarine service and partly to train crews on air-independent propulsion in preparation for the Viking class. However, in June 2004, the Danish parliament voted to end the submarine service. On 27 October 2004, Kronborg was decommissioned at Karlskrona and returned to Sweden.

She was restored to her original name of Näcken upon her return to Swedish control. She was scrapped in Karlskrona during 2015-2016.


HSwMS Neptun:
HSwMS Neptun (Nep) is the second of three Näcken-class submarines, built to operate in the Baltic. Neptun entered service in December 1980. The next year she was involved an international incident when the Soviet submarine U 137 ran aground outside Karlskrona.

The Näcken class were among the first Swedish submarines to have onboard computers. Her task in the eventuality of war would have been to attack enemy shipping and surveillance duties.

Neptun was decommissioned in 1998 and laid up in Karlskrona. In 2008 she was donated to the Naval Museum Marinmuseum of Karlskrona, Sweden, where she is after restoration on display since 2014.
