an autonomous force, independent of the Belgian Army. From September 1953 to 1960, the Advanced Pilots' School () operated Harvards from the Kamina military base in the Belgian Congo. Seemingly about 60 Harvards were at the base. Post-Cold War reforms At the beginning of the 1990s, the end of the Cold War caused the Belgian government to restructure the Belgian Armed Forces in order to cope with the changed threats. The Belgian Air Force was hit hard and saw its strength more than halved with the disbanding of the 3rd Tactical Wing in Bierset (1994); the disbanding of the 1st Fighter Wing in Beauvechain; the 9th Training Wing in Sint-Truiden Air Base; and the Elementary Flying School in Goetsenhoven (1996). In 2002, the Belgian government decided to emulate Canada and impose a "single structure" on its armed forces in which the independent Belgian Air Force ceased to exist. The Belgian Air Component (COMOPSAIR being the HQ) consists of the 2nd Tactical Wing in Florennes Air Base and the 10th Tactical Wing in Kleine Brogel Air Base, both flying F-16s in four squadrons. Out of the 160 F-16s originally bought by Belgium, only 105 were upgraded; with further reductions to 72 aircraft in 2005; and planned to 60 by 2012. The 1st Wing at Beauvechain Air Base is assigned for the training of pilots, using the piston-powered Aermacchi SF.260 for elementary training, and the Alpha Jet for advanced training. Advanced combat training is done on F-16's at Kleine Brogel. COMOPSAIR still operates the Lockheed C-130 Hercules in the 15th Air Transport Wing based at Melsbroek Air Base, planning to replace them by seven Airbus A400M transport aircraft. VIPs are transported with Embraer 135/145 jets, Dassault 20/900, and the Airbus A321. The Sea King SAR helicopters were phased out in March 2019 after more than 40 years of service and replaced by NH-90s (4 NFH + 4 TTH). The Alouette III helicopters flown for the Belgian Navy in a utility-role was phased out in 2021. In 2004, as part of the unified structure, the Army Aviation units of the Wing Heli were transferred to the COMOPSAIR. These contain the Agusta A109 attack helicopter, and the Alouette II training and recce helicopter. In 2005, the Belgian Alpha Jets moved to Cazaux in France to continue the Initial Operational Training, while the Advanced Jet Training was done on French Alpha Jets at Tours. As
