Spanish Air Force
Since its creation, Torrejon Air Base was also the base of a Spanish Air Force fighter wing, an aerial firefighting group and the flight test group of the Spanish Air Force (Ala 12 of the Spanish Air Force, the 54 Flight Test Group and the 43 Grupo dedicated to aerial firefighting). Currently the Ala 12 of the Spanish Air Force operates two squadrons equipped with the McDonnell Douglas F/A-18 Hornet, the 54 Flight Test Group operates with a very diverse range of airplanes and the 43 Grupo operates with Bombardier 415 and Canadair CL-215. In order to fill the space left by the withdrawal of USAF, the Spanish Air Force moved into Torrejon Air Base the following units that were not based there before: the 45 Grupo dedicated to VIP transport and the 47 Grupo dedicated to electronic warfare.
