Unveiled at IDEF 2025, the domestically developed Kaşif XL will support Turkey’s expanding offshore energy exploration operations in regions such as Somalia, Libya, and Pakistan.
As Turkey prepares to extend its deep-sea energy exploration efforts beyond the Black Sea, a new high-tech player is emerging as a key enabler: Kaşif XL, an unmanned underwater vehicle (UUV) developed by Turkish defense and technology firm ARMELSAN.
First introduced to the public during the 17th International Defence Industry Fair (IDEF 2025) in Istanbul, Kaşif XL represents a significant leap in Turkey’s subsea capabilities. With the ability to operate at depths of up to 4,000 meters and powered by eight thrusters generating 250 horsepower, the system is designed to meet the demands of deepwater drilling operations in foreign waters.
From the Black Sea to the World
Speaking at IDEF, ARMELSAN General Manager Can Emre Bakım recalled that Turkey began its deep-sea drilling journey in 2020 under the Ministry of Energy. At that time, operations were limited to the Black Sea, where depths typically did not exceed 3,000 meters. Kaşif’s earlier models were tailored to that environment and operated at around 200 horsepower.
“Back then, both ARMELSAN and our institutional partners gained valuable experience,” Bakım said. “This operational knowledge became the foundation for developing the more powerful and capable Kaşif XL.”
Today, Turkey’s energy strategy has evolved. With new agreements signed with countries such as Somalia, Libya, and Pakistan, Turkish drilling vessels are preparing to operate in deeper, more complex offshore environments—often exceeding 3,000 meters in depth.
“In response to these needs, we launched the XL model. Kaşif XL can operate at depths of 4,000 meters and will become a critical asset in Turkey’s overseas energy exploration missions,” Bakım added.
Dual Use Technology at IDEF
While IDEF 2025 is primarily focused on defense systems, it also showcases cutting-edge civilian technologies. Kaşif XL is a prime example of this dual-use innovation, built with the needs of both energy and defense sectors in mind.
Described by Bakım as the “eyes, ears, arms, and hands” of offshore drilling ships, Kaşif XL enables precise underwater inspection, maintenance, and intervention operations—critical tasks in deep-sea environments where human presence is not feasible.
Energy Security and Export Potential
Turkey currently holds the fourth-largest drilling fleet in the world, a testament to its growing ambition to secure long-term energy independence. As global demand for energy continues to rise, countries are accelerating exploration efforts, especially in Eastern Europe and East Asia.
“These preliminary studies offer insight into the presence of resources, but real answers come only after drilling begins. That’s where our expertise and technology come in,” Bakım noted.
While Kaşif XL will first be deployed in Turkish-led drilling operations, ARMELSAN is already preparing for international service exports, positioning itself as a global supplier of advanced subsea robotics for the energy sector.
