In September 1980, the first Hawk T.53s were delivered to Wing Pendidikan 1 and were operated next to the venerable old L-29s, initially using the LL-53.. serial range, later changed to TT. In 1991, BAe and Indonesian Aerospace (IPTN) signed an agreement for collaborative production of the Hawk and more orders were anticipated, but exports were eventually blocked due to concerns over Indonesian human rights, particularly in East Timor. However in June 1993, the TNI-AU successfully ordered eight Hawk Mk.109s and 16 Mk.209s from BAe, supplemented by 16 additional Mk.209s in 1996
