Foundation of the TAFF
Turkish Armed Forces Foundation (TAFF) was established as a result of merging of Land, Naval and Air Force Foundations, that were established in the 1960s and 1970s with the donations of the Turkish people in order to develop the defence systems and products of the Turkish Armed Forces based on modern technology, under the TAFF Law no. 3388 on 17 June 1987 and started its activities on 26 September 1987.
