Commissioned naval ships are given the prefix "RAS," short for "Royal Aloian Ship." Non-commissioned ships receive the prefix "ANS," short for "Aloian Navy Ship." Coast guard vessels are given the prefix "ACGV," which is short for "Aloian Coast Guard Vessel."
The navy traces its history to a small fleet of ships established by the government of Saint Petersburg, even before the Baltic League existed. This fleet was established to defend Saint Petersburg's prime location at Saint Peter's Channel, which allowed them to control almost all trade between the Baltic Sea and the west.
Saint Petersburg was a founding member of the Baltic League and it brought its growing navy with it. This navy became a national navy in 1417, following the Peace of Halle. In 1593, it became the Royal Aloian Navy with the official establishment of the Kingdom of Aloia.
