Altair-class training ship
The Altair-class is a series of training ships in use by the Swedish Navy.
History
In the early 2000s, after the ageing fleet of outdated World War II-era minesweepers used as training ships could no longer meet safety requirements for operation, the Swedish Defence Materiel Administration sought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. Despite this, the original plan to acquire six ships of the class proved too costly, and only five ships could be commissioned within the available budget.
Construction of the vessels began shortly thereafter, with deliveries taking place between 2007 and 2009.
Etymology
The ships of the class were first named in 2009 through a collective agreement by the then Chief of Defence, Håkan Syrén, the Chief of Navy, Anders Grenstad, and the Chief of Materiel, Leif Nylander. The names adopted were the last five names of the earlier naming convention of the Swedish Plejad-class torpedo boats, in which all vessels are named after well-known stars and constellations.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.As training ships, the aluminium hulls of the Altair-class vessels are relatively small compared to those of regular warships, measuring in length with a beam of, and displacing a maximum of of water, resulting in a draught of approximately. All in all, the expected service life of these vessels is approximately 25 years.
For propulsion, the vessels are fitted with two MTU diesel engines, providing a combined output of and enabling a maximum speed of approximately.
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.
