Grumman US-2N Tracker (160) as used by the Royal Netherlands Navy (MLD) at the Military Aviation Museum, Kamp Zeist (the Netherlands)
The Grumman S-2 Tracker (previously S2F prior to 1962) was the first purpose-built, single airframe Anti-Submarine Warfare (ASW) aircraft to enter service with the United States Navy (USN). Designed and initially built by Grumman, the Tracker was of conventional design with twin engines,
a high wing and tricycle undercarriage. The type was exported to a number of navies around the world. Introduced in 1952 the Tracker saw service in the United States Navy until the mid-1970s with a few aircraft remaining in service with other air arms into the 21st century.
Argentina and Brazil are the last countries to still use the Tracker.
The Royal Netherlands Navy received 28 S-2A (S2F-1) aircraft under MDAP from United States Navy in 1960. 17 additional CS-2A (CS2F-1) aircraft formerly operated by the Royal Canadian Navy were delivered between December 1960 and September 1961 after being overhauled by Fairey Canada. These aircraft were operated from Valkenburg Naval Air Base in the Netherlands as well as from the light carrier HNLMS Karel Doorman, until a fire in 1968 took that ship out of Dutch service. A total of 18 aircraft were converted to S-2N (for Netherlands) standard by Fairey Canada in 1968–1970 for ASW (Anti-Submarine Warfare) and MR (Maritime Reconnaissance) use with 1 Squadron (at Hato International Airport), of which four were converted to US-2N trainer/transport standards in May 1971. Most of the de Havilland Canada-built CS-2As were scrapped by 1970 or used for ground instruction. The last Tracker in MLD service was withdrawn in January 1976, with some transferred to the Turkish Navy. The Netherlands Naval Aviation Service (Marine-Luchtvaartdienst or MLD) is the naval aviation branch of the Royal Netherlands Navy.
