On August 17, 2021, a protocol was signed between the Presidency of Defense Industries (SSB), ASELSAN, and ARMELSAN, at the 15th International Defense Industry Fair IDEF '21 to develop a new generation multi-static sonar suite to be used in TF-2000 Destroyers with national means. 

With this multi-static sonar suite, it will be possible to precisely detect underwater threats across a wide area by enabling joint operation (data fusion) of sonar systems on the same ship or other surface ships with helicopter dipping sonars and sonobuoys that are operating in a compatible frequency band (will be able to communicate with each other via the link). The term 'bi-static' refers to two simultaneous active sources working together, and 'multi-static' is when more than two simultaneous active sources work together. In this respect, the DÜFAS and TF-2000 Sonar Suite are designed with multi-static capability.
