Emergency Underwater Telephone (EUT), developed by KoçSavunma for Preveze submarines, has completed the Factory Acceptance Tests (FAT). The company announced on March 17, on its website that the acceptance tests were carried out between 20-22 December 2021.


EUT is used in cases where the submarine cannot surface, and the submarine's supply can not power the conventional underwater telephone. The system offers different operating modes functioning as a telephone, telegram, beacon.
The EUT can be operated at standard NATO communication transmitters and frequencies the user selects. In addition to its battery, the system can draw power from the onboard power supply. The system has an SOS function for emergencies.
In its current form, the product can be used not only aboard submarines but also in small boats and vessels that lack the power and space to integrate classic underwater telephones. Furthermore, owing to its scalable and digital-based infrastructure, the product can be adapted to non-emergency situations (such as tactical communications) aboard larger ships and submarines.
The EUT will be installed first on Preveze Submarine.
