Over-the-Horizon Power for the Blue Homeland
Using its technological know-how and capabilities, ASELSAN brought Turkey's first indigenous and national over-the-horizon anti-submarine warfare sonar, the Low Frequency Active Sonar System (LFAS), to the Blue Homeland with completely indigenous technology.
According to the statement made by ASELSAN, DÜFAS, developed in line with the needs of the Turkish Naval Forces Command under the leadership of the Presidency of Defense Industries (SSB), enables the detection of underwater threats such as submarines and torpedoes from long distances.
DÜFAS adds strength to the Turkish Navy’s power in the Blue Homeland with its depth-changeable active and passive sonar capabilities and superior technology.
The first and only towed active sonar system designed and produced domestically, DÜFAS broadcasts acoustic signals through active sonar components.
DÜFAS, which creates an underwater tactical picture by collecting the reflections of the transmitted signal from the targets with passive sonar, enables the detection and tracking of underwater threats at long range and with high accuracy.
Enemy submarines are no longer a threat to the Turkish navy
Drawing attention with its sonar performance modeling capability, DÜFAS stands out with its architecture suitable for bistatic/multi-static operation. With the technical features of DÜFAS, enemy submarines are no longer a threat to the Turkish navy.
In addition to detecting threats such as submarines, the system developed by ASELSAN also detects threats such as torpedoes by listening to ambient noise in passive sonar mode. DÜFAS also eliminates the risk by activating countermeasure equipment when it detects a torpedo threat.
In his post on X, Prof. Dr. Haluk Görgün, President of the Presidency of Defence Industries, said: “On the anniversary of the March 18 Çanakkale Victory, a tribute to our nation and the spirit of our glorious ancestors who said ‘Çanakkale is invincible’. DÜFAS, an important product of ASELSAN engineering, was developed to detect threats under the sea. With its 360-degree all-round scanning capability, DÜFAS, which can effectively detect submarines and torpedoes, will add strength to the power of our glorious navy.”
