846 Naval Air Squadron

846 Naval Air Squadron is a squadron of the Royal Navy's Fleet Air Arm.

Between December 1979 and the summer of 2013, 846 Naval Air Squadron operated the Westland Sea King HC4 helicopter to provide troop transport and load lifting support to 3 Commando Brigade Royal Marines. Based at RNAS Yeovilton in Somerset, 846 NAS stood down in the summer of 2013 and its personnel, buildings and equipment were amalgamated into 845 Naval Air Squadron.

The squadron stood up on 30 September 2014 with the AgustaWestland Merlin MK3 and it now holds the Operational Conversion Flight and Maritime Counter Terrorism Role.

Second World War
846 Naval Air Squadron was established in April 1943 at the Naval Air Station Quonset Point, Rhode Island, United States. It was equipped with 12 Grumman Avenger I torpedo bombers. Two months later the squadron embarked on the escort carrier HMS Ravager (D70) and was transferred to the UK. Before being assigned to HMS Tracker (D24) in January 1944, four Grumman Wildcat V fighters were added to 846 NAS. HMS Tracker was first assigned to convoys going to Gibraltar, then to Murmansk. On the latter voyage, aircraft from 846 NAS attacked eight German U-boats.

HMS Tracker was damaged in June 1944 in a collision with the Canadian frigate HMCS Teme (K458) while forming part of the naval screen for the D-Day landings, and the squadron disembarked to RAF Limavady airfield, Northern Ireland, joining 15 Group RAF Coastal Command. A month later 846 NAS was assigned to HMS Trumpeter (D09), mainly laying mines off Norway until September 1944.

In December a detachment was formed and transferred to HMS Premier (D23) for a few days. The remainder of 846 NAS operated from HMS Trumpeter or RNAS Hatston in Orkney up to May 1945. On 4 May 1945, twelve Avenger and four Wildcat aircraft of the squadron took part in Operation Judgement, Kilbotn, the last air-raid of the war in Europe. The fighter flight was disbanded after the end of hostilities in Europe.

846 NAS was then assigned to the 4th Carrier Group and should deploy to the Far East aboard the fleet carrier HMS Illustrious (87). However, a change of plans led to the squadron becoming a trials unit. It was renumbered 751 NAS and was disbanded at Machrihanish, in September 1945.

Borneo
846 NAS was reformed in 1962 as a Commando squadron equipped with the Westland Whirlwind HAS.7. It was deployed to Borneo aboard the commando carrier HMS Albion (R07) and flew in support of actions against guerrillas during the Indonesia–Malaysia confrontation. British Army units gave 846 NAS the nickname 'Junglies' in Borneo, which the squadron has kept until today.



After returning for the Far East, 846 NAS was disbanded again, only to be reformed in 1968 at RNAS Culdrose. This time the squadron was equipped with the Westland Wessex HU.5. The squadron deployed aboard the dock-landing ship HMS Fearless (L10) and conducted cold weather trials in Norway. In May 1972, the squadron was relocated to RNAS Yeovilton as the Wessex Headquarters and Trials Squadron. In February 1979 the squadron was deployed aboard the commando carrier HMS Bulwark (R08). In December of the same year 846 NAS started to convert to the Westland Sea King HC.4.

Falklands War
In April 1982, 846 NAS embarked aboard the carrier HMS Hermes (R12) as part of the Royal Navy task force in the Falklands War. During the war 846 NAS Sea King's flew over 2800 hours, completed 10,000 individual troop moves and transported more than 81,600 t of freight.

In 1983, detachments were deployed aboard the carriers HMS Hermes and HMS Invincible (R05). Between November 1983 and March 1984, a detachment of three Sea Kings was deployed aboard HMS Fearless and RFA Reliant to the coast of Lebanon supporting British troops involved in peacekeeping operations in Lebanon during the Lebanese Civil War and took part in the eventual withdrawal of British troops and the evacuation of civilians from Beirut, airlifting 521 civilians on 10 March 1994. The squadron was awarded the Boyd Trophy for these operations.

Gulf War
In 1990, 846 NAS took part in the Gulf War. In six weeks the squadron flew a total of 1200 hours in support of Allied ground forces. After the end of hostilities the squadron moved to northern Iraq to assist with humanitarian relief for the Kurds. An element of 846 NAS also remained in theatre post Gulf War to assist with mine clearance operations, alongside an element from 845 NAS. These aircraft were then deployed to Bangladesh aboard RFA Fort Grange to assist with the relief effort after the 1991 Bangladesh Cyclone as part of Operation Manna.

Yugoslav Wars
In January 1993, 846 NAS was deployed until March aboard the carrier HMS Ark Royal to the Adriatic as part of UN operations in Yugoslavia. Shortly after returning to the UK the squadron was deployed to Northern Ireland to replace 707 NAS to provide support to security forces. It returned to the Balkans to provide air support for Multi-National Division-SW (SFOR), which was then commanded by the British, in Bosnia. This deployment lasted until 2002.

Afghanistan
Since 2007, the 10 Sea King HC4/HC3i helicopters of 846 NAS were committed to the Kandahar and Helmand provinces in Afghanistan in support of 3 Commando Brigade Royal Marines.

Present day
846 NAS re-equipped with the AgustaWestland Merlin MK3 on 30 September 2014 at RAF Benson. The squadron moved back to its usual home of RNAS Yeovilton in March 2015. As of 12 March 2019 846 NAS had received the first of its Merlin MK4 helicopters, marking another major step in the transition from Royal Air Force to Royal Navy dominance in the Commando warfare role.
