TÜBİTAK Active Sonar for AY Class Submarines

Issue 96

The TÜBİTAK MRC Materials Institute Underwater Acoustic Laboratory participated in the 9th Naval Systems Seminar which was organized with the support of FCEA-TR, METU-BILTIR, TSS News Group, the Presidency of Defense Industries (SSB) and the Turkish Naval Forces Command (DZKK) on October 14-15, 2019, at the METU Culture and Congress Center. The Active Sonar System developed for Submarine Platforms attracted a great deal of attention at the TÜBITAK MRC Materials Institute booth. According to the information we received, the Active Sonar System has been installed to three AY Class Submarines as part of the contract signed, and two of the submarines have returned to service following the active sonar system integration process. The acceptance process of the Third AY Class Submarine continues as of October 14, 2019. The Active Sonar System, which was initially integrated into the sails of three AY Class submarines, consists of subsystems such as, Electronic Control Unit, Power Amplifier Unit, Transmitter Console Unit, EMI Filter Unit, and Connection Box. The Active Sonar System, which was placed in the front part of the sail, has a 20-degree forward view. The Active Sonar System is used both to detect the positions of incoming torpedoes more accurately and to determine if there are any ships above during surfacing. Another product exhibited at the TÜBİTAK MRC Materials Institute Underwater Acoustic Laboratory booth was the TBT-01 Sonar Transducer Element used in the wet-end of the FERSAH Hull-Mounted Sonar System, which will be installed under the BARBAROS Mid-Life Upgrade (MLU) Project.
