Ambala was one of the oldest and largest airbase inherited from the British for the IAF. The then Advanced Flying Training School operating from there used to operate Harvards and Spitfires. Later on, Ambala AFS operated Vampires, Toofanis, Mysteres and Hunters in a combat role. It was from this airbase that Spitfires and Harvards flown by Instructors took part in the early days of fighting in the Srinagar valley in the 1947-48 Kashmir Operations. Today the Airbase houses 7 Wing operating Jaguars and MiG-21 Bisons.
