The Netherlands Naval Aviation Service (Dutch : Marineluchtvaartdienst, shortened to MLD) is the naval aviation branch of the Royal Netherlands Navy.
Although the MLD was formed in 1914, with the building of a seaplane base at De Mok, Texel, it developed slowly in the inter-war years due to limited budget. After the graduation of the first pilot group in 1915, on August 18, 1917, the MLD was founded under official decree and De Mok became the main base. At this time, the emphasis was on seaplane operations in the Dutch East Indies where Dornier Wal aircraft enabled patrols of the large archipelago in 1926. The perceived threat from Nazi Germany in the 1930s accelerated the development of air capability and the purchase of new equipment.
The German invasion of the Netherlands on May 10, 1940, rapidly overwhelmed Dutch resistance and the MLD aircraft were redeployed to France before the Dutch formally surrendered on 15 May. Shortly after, the MLD was ordered to Britain, where Dutch personnel formed No. 320 Squadron RAF, Coastal Command, in June 1940. A second squadron, 321 Squadron, was also formed, but later merged with 320 Squadron. Other MLD personnel served on MAC ships in the Fleet Air Arm's 860 and 861 Naval Air Squadrons, flying the Fairey Swordfish.
At this time efforts were made to strengthen the MLD in the Dutch East Indies. When the war started in December 1941, the MLD numbered 130 aircraft. The main types were 37 Dornier Do 24 K-1 flying boats and 36 Consolidated PBY-5 Catalina flying boats. [1] The major base was at Morokrembangan Naval Air Base near Soerabaja in eastern Java. The MLD had secondary bases as well as seaplane tenders that enabled it to spread out and cover the entire Netherlands East Indies. It was organized into 18 squadrons (GVT, Groep Vliegtuigen) of about three aircraft each to provide reconnaissance, anti-submarine patrols, convoy escort in support of Dutch forces. The MLD did not have radar. The MLD fought about 95 combat actions, sank one Japanese ship (the destroyer Shinonome), damaged some others, shot down a few Japanese aircraft and inflicted some casualties on Japanese personnel on the ground. [2] That was not enough to stop the Japanese, and eventually the MLD was forced to evacuate to Ceylon and Australia. They lost 95% of their aircraft and 50% of their personnel. [3]
On March 3, 1942, nine MLD Dornier and Catalina flying boats were destroyed in the Japanese air attack on Broome, in Australia. About 58 MLD personnel were killed, wounded, or missing. [4] Later that year, on July 1 in Ceylon, 321 Squadron was re-formed under the command of Willem van Prooijen, with MLD Catalinas. The PBYs in Australia were transferred to Ceylon, and the surviving Dorniers were sold to the Australian government. The flight school was relocated to the United States.
The Royal Netherlands Military Flying School (see nl:Royal Netherlands Military Flying School) was established in the United States, at Jackson Field (also known as Hawkins Field), Jackson, Mississippi, operating lend-lease aircraft, training all military aircrew for the Netherlands. The intention was to return to the Netherlands and to participate in the war against Japan. After liberation, the main MLD base was established at Valkenburg, with De Kooy as the overhaul and repair base.
The British escort carrier HMS Nairana was obtained on a two-year loan from the Royal Navy and renamed HNLMS Karel Doorman. In March 1948 a light fleet carrier, HMS Venerable, was purchased from the Royal Navy to replace the loaned one, and also renamed HNLMS Karel Doorman. Aircraft carried aboard included the fighter-reconnaissance and anti-submarine Fairey Firefly.
The main roles of the MLD were maritime patrol, anti-submarine warfare and search and rescue. From 1953, with the creation of NATO, the MLD received substantial aid from the US, including 12 Lockheed PV-2 Harpoon, Lockheed P2V Neptune, Grumman TBF Avenger and 43 Grumman S-2 Tracker (1955–1974) aircraft.
320 and 321 Squadrons were stationed at NAS Valkenburg and was known as the group aircraft. Helicopters were stationed in De Kooy and on ships and were known as the group helicopters. 860 Squadron remained in service to operate the remaining NH-90 helicopters, but as part of the Defence Helicopter Command.
In the late 1960s, the aircraft carrier was replaced in the anti-submarine role by a squadron of Westland Wasp helicopters operated from anti-submarine frigates. These helicopters were replaced by Westland Lynxs, and these were replaced themselves by NH-90 helicopters.
320 and 321 Squadrons operated 19 Neptunes (1961–1982) and 9 Breguet Atlantic (1969–1984), which were later replaced by 13 Lockheed P-3 Orion CUP (1982–2005).
In 2003, it was announced that NAS Valkenburg would close in 2006. All the Orions were sold to Germany (8) and Portugal (5). Naval squadrons 320 and 321 were disbanded. [5]
In 2008, the navy helicopters (Westland Lynx) and crews of naval squadrons 7 and 860 based at NAS de Kooy were transferred to the Defence Helicopter Command (DHC) as were the Dutch Air Force helicopters. All Dutch military helicopters are now under one single command which is neither navy nor air force. No. 7 Squadron is to become a small training squadron, while 860 Squadron will become much larger and is designated DHC's maritime squadron with a large navy component. NAS de Kooy was renamed Maritime Airstation de Kooy. [6]

The Fleet Air Arm (FAA) is the naval aviation component of the United Kingdom's Royal Navy (RN). The FAA is one of five RN fighting arms. As of 2023 it is a predominantly "rotary" force, with helicopters undertaking roles once performed by biplanes such as the Fairey Swordfish. It operates the F-35 Lightning II for maritime strike and the AW159 Wildcat and AW101 Merlin for commando and anti-submarine warfare.
The Royal Netherlands Navy is the naval force of the Kingdom of the Netherlands. It is one of the four Netherlands Armed Forces. It was founded on 8 January 1488, making it the third oldest naval force in the world.
The Westland Wasp is a small 1960s British turbine powered, shipboard anti-submarine helicopter. Produced by Westland Helicopters, it came from the same P.531 programme as the British Army Westland Scout, and is based on the earlier piston-engined Saunders-Roe Skeeter. It fulfilled the requirement of the Royal Navy for a helicopter small enough to land on the deck of a frigate and carry a useful load of two homing torpedoes.
Royal Naval Air Station Yeovilton, commonly referred to as RNAS Yeovilton, is a military airbase of the Royal Navy, sited a few miles north of Yeovil, in the English county of Somerset. It is one of two active Fleet Air Arm bases, the other being RNAS Culdrose). RNAS Yeovilton is currently home to the Royal Navy Wildcat HMA2, along with Army Air Corps Wildcat AH1 helicopters, as well as the Royal Navy's Commando Helicopter Force Merlin HCi3/4/4A and Wildcat AH1 helicopters.
HNLMS Karel Doorman (R81) was a Colossus-class aircraft carrier of the Royal Netherlands Navy. Formerly the British ship HMS Venerable, she was sold to the Netherlands in 1948 as a light attack carrier. In 1960, she was involved in the decolonization conflict in Western New Guinea with Indonesia. In the mid 1960s, her role was changed to anti-submarine warfare carrier and only ASW aircraft and helicopters were carried. An engine room fire took her out of service in 1968. She was sold to Argentina in 1969 and renamed ARA Veinticinco de Mayo.
