Turkish defense firm to meet Indonesia's underwater security needs

Turkish defense firm Armelsan and Indonesian state-owned enterprise PT-LEN signed an agreement in Jakarta for the former to protect the country's key facilities from underwater threats.

The two companies' deal was signed at the Indo Defence 2025 expo in Indonesia.

Erdem Tumdag, Armelsan's director of sales, business development, and corporate communications, told Anadolu that the company has completed a number of projects in Türkiye and other countries to ensure underwater security for critical facilities and ports.

“We will start a joint project with PT-LEN for the protection of critical facilities at sea and under the jurisdiction of the navy—this project has the potential to evolve into a joint production in the future,” he said.

Armelsan is one of Türkiye's leading defense firms operating in underwater acoustic systems and technologies, particularly focused on sonar systems, remotely operated and unmanned underwater vehicles, and underwater sensor systems to detect, track, and neutralize threats.

The remote-controlled unmanned underwater vehicle Kasif is used to surveil and protect critical infrastructure, while underwater sensor systems collect and analyze data.

Armelsan plays a key role in the underwater security of critical facilities and ports, including diver detection and anti-mine sonars, remotely controlled unmanned vehicles, and submarine defense systems.
