The Turkish Ministry of Defence announced today that the Turkish Navy conducted a test of the Roketsan-made AKYA heavy weight torpedo (HWT) from TCG Preveze (S-353) in the Sea of Marmara. The event marked the first live-firing from an upgraded Preveze-class (Type 209/1400) submarine, which is currently fitted with the indigenous MUREN combat management system (CMS) within the scope of mid-life upgrade. AKYA HWT has been fired by two fire control systems so far; in the first test, the torpedo was fired by the ISUS 90-33 fire control system, while the second test was conducted by MÜREN CMS.

The MÜREN (Milli Üretim Entegre Sualti Sava? Yönetim Sistemi) project has been carried out by TUBITAK BILGEM in collaboration with the Turkish Navy and Golcuk Naval Shipyard. Beginning in 2015, the MÜREN-AY program involved the delivery of one ground station system and two submarine systems. AY-class (Type 209/1200) submarines, were outfitted with the capacity to launch modern heavyweight torpedoes, conduct target motion analyses (TMA) utilizing sonar, periscope, and ESM data, and manage tracks using an indigenous weapon control unit. MÜREN CMS is also compatible with Reis-class (Type-214 TN), which are under construction and scheduled to enter service in the following years.
