STM Unveils Long-Range Kuzgun Drone and Tengiz UUV, Signals Gulf Partnership Openness

At the SAHA defense exposition in Istanbul, Turkish state-owned contractor STM displayed four new unmanned aerial vehicles and its first unmanned underwater system. The event highlighted STM’s push to expand its product line beyond traditional shipbuilding into autonomous air and sea platforms.

STM General Manager Ozgur Guleryuz noted the company is actively seeking collaboration with Middle Eastern and Gulf states. Although STM is Turkey’s largest shipbuilder, it relies on subcontractors for production and integrates systems before delivery.

The Kuzgun attack UAV is a fixed-wing loitering munition with a range exceeding 1,000 km, a cruising speed of 180 km/h, and a high‑explosive fragmentation warhead. Guleryuz said employing Kuzgun in a swarm is already on the agenda, with ongoing flight tests and strong interest despite no current contract.

The Tengiz UUV family measures 11.2 meters in length, can operate at depths of 400 meters while traveling at 8 knots, and carries heavy torpedo launchers plus smart loitering munitions for intelligence, surveillance, reconnaissance and combat missions, including anti‑submarine and electronic warfare roles.

STM’s unveiling shows a dual‑track strategy: extending its aerial strike reach with long‑range loitering munitions and adding underwater strike capability through a sizable autonomous vehicle. By emphasizing swarm tactics for Kuzgun and modular payloads for Tengiz, the company aims to meet diverse mission requirements that appeal to Gulf navies seeking layered defense systems.

Such partnerships could shift the procurement landscape in the Persian Gulf, where navies are increasingly investing in autonomous systems. The explicit openness to technology transfer and local production suggests STM is positioning itself as a partner for Gulf states looking to build indigenous unmanned capabilities while leveraging Turkish engineering expertise.

Monitor whether STM signs memoranda of understanding with Gulf nations for joint development or local assembly of the Kuzgun swarm systems and Tengiz underwater platforms, and how those agreements affect regional procurement timelines.
