Turkish Navy Test-Fires New AKYA Heavy Weight Torpedo

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 within the scope of mid-life upgrade.

“Firing tests of the nationally developed AKYA training torpedo from our submarines continue. For the first time, a successful launch was conducted from our submarine TCG PREVEZE in the Sea of Marmara using the battle management system “MÜREN”.”

This event was the second known submarine-launched live firing test of the AKYA HWT. The previous test was conducted by the Type 209/1400 TCG Gür submarine in the Sea of Marmara on January 20, 2021.

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 MUREN.

About MÜREN Project:

The consols of MUREN CMS

The MÜREN (Milli Üretim Entegre Sualti Savaş Yönetim Sistemi – means Indigenously Produced Integrated Underwater CMS) project has been carried out by TUBITAK BILGEM (The Scientific and Technological Research Council of Turkey affiliated with the Industry and Technology Ministry) in collaboration with the Turkish Navy’s Research and Development Command (ARMERKOM), and Golcuk Naval Shipyard.

The project consists of two main programs, MÜREN-AY and MÜREN-PREVEZE.

MÜREN-PREVEZE, a program aimed at indigenously modernizing the combat management systems of Preveze-class submarines, was initiated in 2017 with the collaboration of the same establishments as MÜREN-AY. Meteksan Savunma joined the project as a subcontractor in July 2018, and it is in charge of developing pre-electronic equipment that amplifies and transforms analog signals from sensors to digital, as well as signal processing and beam shaping hardware and software for these digital signals.

The MÜREN-PREVEZE contract includes the delivery of one ground station system and four submarine systems. The ISUS-83/2 CMS onboard Preveze-class submarines are being replaced with MÜREN CMS as part of the project. When finished, the Preveze-class submarines will be able to launch DM2A4 SeaHake and indigenous AKYA heavyweight torpedoes in place of Mark 24 Tigerfish.

Because the system is based on the ADVENT CMS developed by HAVELSAN and ARMERKOM, Preveze-class submarines will be compatible with network-centric infrastructure following the upgrade. The MUREN-PREVEZE CMS incorporates the ADVENT-based Link 11, Link 22, JREAP (Joint Range Extension Applications Protocol), Multiple Tactical Data Link Systems, and WAIS (Warship Automatic Identification System) subsystems.

MÜREN CMS is also compatible with Reis-class (Type-214 TN) air-independent propulsion capable submarines, which are under construction and scheduled to enter service in the following years.
