The Danish Navy Air Squadron (Danish: Søværnets Helikoptertjeneste), was the aerial component of the Danish navy, from 1977 to December 31, 2010. Operationally it was directly under command of the Danish Naval Command, but maintenance of the eight Westland Lynx helicopters and training of personnel was in cooperation with the air force. The helicopters were used primarily for fishery patrol, shipboard support and coastal Search & Rescue (SAR) missions.
The tasks and hardware have now been transferred to the air force as Eskadrille 723 (Squadron 723).
The squadron was originally a flight in the air force eskadrille 722 (722nd Squadron) when the first Alouette III helicopter was received in 1962. In 1977 the flight was made into a unit of its own and became a part of the navy, under the name Søværnets Flyvetjeneste (The Naval Air Service).
In 1980-1982 the eight Alouette helicopters were replaced with the new Westland Lynx helicopters.
In 2000 it was decided that Søværnets Flyvetjeneste should be transferred to the air force as a squadron (728th Squadron) and put under operational command of the air force command along with the Army Air Corps (Hærens Flyvetjeneste), but for a political reason only the army units were transferred to the air force (as 724th Squadron). At the same time, all the Danish helicopter units were also to move physically from Værløse Air Station and Vandel Air Station to Karup Air Station. The total number of helicopters in the air force would have been 8 Sikorsky S-61A, 13 Eurocopter AS550C2 Fennec, 16 Hughes H-500C Cayuse and 8 Westland Lynx Mk.90B as well as 14 AgustaWestland EH-101 Merlin under purchase - a grand total of 59 helicopters. International obligations didn't allow for the Danish air force to possess so many helicopters. Because of that the Naval Air Service was transformed into the Naval Air Squadron on 1 January 2004.
