The '''''Näcken''-class submarines''', also known as the A14 type, were built for the ] in the late 1970s. The boats were authorised in 1972 and the programme was completed in 1981. All boats were built by ] in Karlskrona. The boats had a teardrop hull and diving depth was 150m. Between 1987 and 1988 the ''Näcken'' was converted to ] (AIP) using a closed cycle ]. This technology increased underwater endurance to 14 days and has been adopted in subsequent Swedish submarines. |
