In 2006 Turkey’s leading underwater acoustics and sonar system manufacturers such as ASELSAN, METEKSAN DEFENCE and TÜBİTAK MAM have started their studies on the development of underwater acoustic systems and on the indigenization of naval electronic systems, particularly those within the scope of the MİLGEM Project. In this context, since technology transfer from abroad was not possible, they have made significant investments in the field of underwater acoustic system technologies, which previously did not exist in Turkey. 

Making significant contributions to the activities of the Turkish Naval Forces, including MİLGEM and İSTİF Class Frigates and the modernization of the submarines in its inventory, as well as supplying underwater acoustic systems for export customers (including Pakistan, Indonesia and Ukraine) today ASELSAN and METEKSAN DEFENCE are listed among global players in underwater acoustics and sonar systems. The companies today have reached the point where they can provide indigenous solutions for all types of sonar system requirements (towed, hull mounted and dipping) of both surface and under-surface platforms.
