845 Naval Air Squadron HISTORY

  • Action in the Far East

    Apart from two years flying torpedo bombers in the second half of World War 2, 845 Naval Air Squadron has been a cutting-edge helicopter formation for more than half a century. The squadron was originally formed in February 1943 Flying Grumman Avenger torpedo bombers, seeing extensive action in the Far East in 1944 and 1945.

  • The First Anti-Submarine Helicopter Squadron

    Disbanded at the war’s end, 845 reappeared in 1955 with Sikorsky S55s and, from 1957, Westland Whirlwinds, as the first anti-submarine helicopter squadron in the Fleet Air Arm. Despite this specialist role, the squadron demonstrated the versatility of the helicopter during the Suez Crisis of 1956 by carrying troops ashore in a ‘vertical assault’.

  • The First Commando Helicopter Squadron

    The squadron was disbanded again in 1959 before reforming in 1962 as the first commando helicopter squadron which saw immediate action in the jungles of Brunei and Borneo, establishing the ‘jungly’ nickname which persists today.

  • Northern Ireland, The Falklands and Kuwait

    845 spent much of the 1970s and early ’80s supporting the security and peacekeeping mission in Northern Ireland, but its helicopters were also sent to the South Atlantic in 1982 to liberate the Falklands. Another invasion half a world away saw the squadron earn its next battle honour during the international effort to drive Saddam Hussein’s forces out of Kuwait.

  • Peacekeeping

    From the end of 1992 until 2005, 845 maintained a permanent presence in the former Yugoslavia supporting UN/NATO peacekeeping operations; the squadron became the longest-serving unit in theatre.

  • Returning to the Gulf

    In 2003 the squadron returned to the Gulf, this time during the campaign to oust Saddam Hussein’s regime in Iraq. Once the dictator had been toppled, the Sea Kings remained in the country for three years supporting stabilisation efforts on the ground.

  • Afghanistan

    After improvements and upgrades to the Sea Kings, and with the mission in Iraq over, 845 was sent to Afghanistan in March 2008 and its men, women and helicopters have been committed there ever since.
