Fall of the Ottoman empire
It is not something that suddenly happened overnight and has been a long time in the making.
From the fall of the Ottoman empire when Turkey completely lacked any defense industry infrastructure whatsoever.
Defense industry of Turkey, General, Wikipedia
Thus, no significant defense industry infrastructure was present during the first years of the Republic and activities in this domain were limited to the establishment of new facilities near Ankara during the Turkish War of Independence.
Local defense industry
To the small scale local defense industries up until 1950.
1923-1950 Wikipedia
Machinery, craftsmen and workmen transferred discreetly from Istanbul and its surroundings at the end of the First World War played a crucial role in winning the War of Independence. Small scale and simple workshops in Ankara, Konya, Eskişehir, Keskin and Erzurum not only provided light weapons and ammunition but also lay the foundation for a sound local defence industry infrastructure.
Foreign aid
Then to an over-reliance on foreign aid between 1950 and 1960 which slowed down their development.
1950-1960 Wikipedia
Instead of improving the local defence industry, foreign aid and foreign procurement were practiced during this period. Because of the Cold War and military and political polarization after the 2nd World War, Turkey met its defence requirements through and in the framework of the NATO.
Within the impact of the increasing foreign aid in the post-IInd World War period, efforts for the development of local defence industry slowed down; orders of the Turkish Armed Forces from the local suppliers decreased, thus military facilities became a part of the Machinery and Chemical Industry Corporation (MKEK) which was formed as a State Economic Enterprise on 15 March 1950.
Over dependence
To the realisation of the downside of foreign aid between 1960 and 1970, and the negative effects of over dependence fuelling the need for a national defense industry.
1960-1970 Wikipedia
It was a period regional conflicts and the Cyprus issue. Cyprus crises in 1963 and 1967 and the Turkish invasion of Cyprus in 1974, the arms embargo imposed on Turkey as a result of this invasion proved the need for a national defence industry. During the crises, Turkey was face with the difficulty of dependence on foreign supply. The deadlock experienced in this period caused to seek ways to reactivate national defence industry.
National defense industry
Then between 1970 and 1980 plans got underway for this national defense industry, and foundations and enterprises were established.
1970-1980 Wikipedia
1970s have been the period in which solid initiatives were put into force so as to establish a national defence industry. As a result of the national reaction to the arms embargo against Turkey, Armed Forces Foundation were established.
The PODI
Then, between 1980 and 1985, the formation of the Undersecretariat for Defense Industries.
1980-1985 Wikipedia
The first step in this direction was taken by the establishment of defence equipment Directorate as a state enterprise. However, the shortcomings stemming from its state-bound status prevented the success and all the properties of that enterprise were transferred to the Undersecretariat for Defense Industries (SSM) which was established in 1985 under the Law No: 3238
Presidency of Defense Industries
The Presidency of Defense Industries was set up in 1985, to build the projects, foundations, enterprises and business that we see today.
Presidency of Defense industries Wikipedia
The Presidency has close relations with the Office of the President of Turkey, the Ministry of National Defense and the Turkish Armed Forces, as well as domestic and foreign defense industry companies. In addition to supporting projects and products based on domestic design and production, SSB gives importance to technological transfer of products and services acquired from foreign suppliers.
Today
Today, all the achievements are very much down to the work of the PODI since its creation.
Todays Turkish defense industry, Wikipedia
Over the last 21 years since its establishment, and as a result of dedicated efforts, the Presidency of Defense Industries (formerly Undersecretariat for Defence Industries) has made real achievements in the creation of a modern national defence infrastructure in Turkey, with highly successful results in certain vital areas. Key defence industrial institutions have been established to meet the requirements of the Turkish Armed Forces through local sources, each of which fill an important gap in their scope of activity.
