Altair-class training ship

In the early 2000s, after the ageing fleet of outdated World War II-era minesweepers used as training ships could no longer meet safety requirements for operation, the Swedish Defence Materiel Administration sought an existing ship class to commission. However, strict requirements made this unfeasible. As a result, a new project was launched in 2004 to domestically design a vessel that could meet all the criteria put forward. This decision ultimately proved to deliver not only more suitable ships but also greater cost-effectiveness. Construction of the vessels began shortly thereafter, with deliveries taking place between 2007 and 2009. == Design ==

Although designed, built, and primarily used as training ships, the class is multifunctional and can assume combat roles if required. Each vessel is capable of being modified into a sonobuoy platform, similar to , for use in anti-submarine warfare. Additionally, a heavy machine gun can be fitted as part of the original design. Complementing the ships, the design allows for 10 personnel to work on each vessel simultaneously, with six students in training and four officers and enlisted crew members on board. == Units ==
