The Royal Swedish Naval Academy (, KSS) was a school for officer training for the Swedish Navy, which operated in various forms between the years 1756 and 1987.
History
1683–1791
In 1683, when the charter was issued that "those who were proposed to become officers in the navy, should undergo a naval officer exam", the navy only possessed the training schools, Mate's and Artillery Schools (Styrmans- och artilleriskolorna) in Karlskrona which was established by Admiral H. Wachtmeister. Later at Sveaborg a naval school for officers and cadets of the Fleet of the Army was established. But it wasn't until 1756, after the cadet corps (paid for by Adolf Frederick in 1748) ceased, that a real sea cadet school, called Cadette Corpsen vid Ammiralitetet i Carlskrona, was established at the Admiralty in Karlskrona with the purpose "to bring viable subjects to the navy". However, it was found, that "not all of the accepted cadets possessed mind and qualities to become naval officers," why the school in 1761 was converted into a reformatory, common for the maritime and land state.
1791–1865
The school ceased in 1791 after a conflagration and the lustschloss Karlberg in Stockholm opened the following year as a Royal War Academy with the task "to prepare skilled subjects to the national land army and navy." For many years, aspirants could, without completing the syllabus at the academy, graduate with approved naval officer exam at the Royal War Academy (1836–49) as well as face a special assessment commission in Karlskrona (1824–64). At the latter location there was a joint advanced course at the mate, skipper and artillery schools, named the Educational Institution for Officers of the Royal Navy in Karlskrona. When the Royal War Academy in 1862 finally was converted into a military application school "for all the army and the navy needed officers," it led the organization to such disorders, particularly with regard to the entry age, education and training, that the school was considered inappropriate for sea cadet's teaching of serviceable professionals.
1865–1916
Since a committee in 1865 issued "proposal for the organization of a naval officer education", the first charter of the Royal Swedish Naval Academy was issued, which began operations in 1867 and the following year received the sea cadets from Karlberg. Until 1911 the school had six classes, each with a one-year course partly from 1 October to about 1 May at the school in Stockholm and partly on board during the summer months, preferably, on seagoing, sailing warship (the corvettes af Chapman, Norrköping, and Freja as well as the frigate Vanadis). Teaching at the school on land involved partly ordinary school subjects mainly the courses which were included in the curriculum of the general secondary schools, to the extent of not less than the requirements for the studentexamen, and partly military subjects, as well at the school on board almost exclusively practical exercises.
Admission was generally permitted only in the school's 1st grade at 14–16 years of age and after the time trial, in which over a period of years also included a so-called aspirant course aboard. Because of the 1909 parliamentary decision the education was rescheduled from 1911. Admission into the school now required passing the studentexamen, and teaching of sea cadets at school, on land and aboard on contemporary warships, comprised almost exclusively of military subjects during a little longer than a three-year course. According to the school issued regulations (8 October 1915), its purpose, in theoretical, practical and disciplinary terms of the naval officer programme, was to execute the training required to gain the lowest officer rank in the navy, and that, in a coastal artillery programme execute a part of the training, which was required to gain the lowest officer rank in the coastal artillery. The school's disciples were called cadets ("sea cadets" and "coastal artillery cadets") and together constitute the Navy Cadet Corps (Marinens kadettkår). The school's operations were divided between school on land for both programmes of two academic years for the naval officer programme and one academic year for the coastal artillery programme as well as a recruit course and school aboard only for the naval officer programme. The academic year at the school on land comprised the period around 21 October-1 May with three weeks of Christmas holidays, recruit course 15 July-1 October (Karlskrona) and the school aboard on the "cadet ship" one winter and three summers.
