  6. Sonar Beacon System

The Sonar Beacon System is one of the most critical systems that a submarine will need in the event of an accident or incident. Sonar Beacon System, developed by KoçSavunma, activates and serves as an emergency pinger by emitting sonar signals in the event of an emergency. These signals convey the precise location of the submarine to ships and rescue units in the area.

Different Frequencies
for Long-Range Detection and Precise Positioning

The Sonar Beacon System can operate automatically or manually at both low (9 kHz) and high frequency (37.5 kHz). Low-frequency transmissions allow for the detection of the submarine at long range, while high-frequency transmissions permit the precise positioning of the submarine at closer ranges.

Independent Power
with Embedded Battery

Powered by its own battery, the Sonar Beacon System operates independently of the submarine’s power system. If the system is not operated, the battery will not need a replacement for 5 years.


The Sonar Beacon System is configurable to the needs of the submarine and the demands of the user.
