STM unveils Kuzgun long-range loitering munition

STM has introduced Kuzgun, a long-range loitering munition designed to give Türkiye a domestically produced system in the expanding market for low-cost deep-strike drones.

Unveiled at SAHA Expo 2026 in Istanbul, Kuzgun has been specified with up to 1,000km range, around six hours of endurance, a 40kg high-explosive fragmentation warhead, a 200kg maximum take-off weight, a cruise speed around 180km/h, rocket-assisted launch, and autonomous navigation using anti-jamming GNSS. The system is designed for pre-planned target attack and terminal dive engagement, placing it between tactical loitering munitions and more expensive cruise-missile-class weapons.

That middle ground has become one of the most competitive areas of defence manufacturing. The use of Shahed-style one-way attack drones in Ukraine and the Middle East has shown how relatively inexpensive systems can impose disproportionate pressure on air defences, infrastructure, logistics hubs, depots, radars, and command sites. Western and NATO-aligned industries are now developing their own equivalents, with the focus shifting from single exquisite weapons towards affordable strike mass.

Kuzgun’s design follows that logic. A long-range loitering munition does not require the survivability, multi-mission sensor fit, or return-to-base capability of a high-end UAV. It needs reliable range, predictable navigation, a useful warhead, tolerable accuracy, electronic warfare resilience, and a unit cost that permits volume production. That combination moves the manufacturing challenge away from maximum sophistication and towards repeatability, modularity, component availability, and production rate.

STM brings an established unmanned systems and naval engineering background to the programme. Türkiye’s wider drone industry is already highly visible through Baykar’s TB2, Akinci, TB3, and Kizilelma platforms, while Turkish companies have also moved into guided munitions, electronic warfare, loitering systems, naval drones, and air defence. Kuzgun adds a deep-strike attritable system to that mix, aimed at sustained campaign use rather than occasional precision engagement.

Keeping such systems affordable while maintaining reliability is a difficult balance. A 1,000km-range loitering munition still needs stable flight control, reliable propulsion, rugged electronics, protected datalinks or mission-loading systems, safe warhead integration, and consistent launch behaviour. If the aircraft is to be produced in quantity, those elements must be assembled with enough discipline to avoid high levels of technical failure before the munition reaches the target area.

GNSS resilience is central to the design problem. Long-range drones now operate in environments where jamming and spoofing are expected rather than exceptional. Anti-jamming GNSS can help, but manufacturers increasingly have to combine satellite navigation with inertial systems, terrain or visual reference methods, hardened receivers, software filtering, and route planning that reduces exposure to known electronic warfare zones. A deep-strike drone that loses navigation confidence becomes a liability rather than an asset.

Kuzgun also shows how the line between drones and missiles is narrowing. Traditional missiles place greater emphasis on speed, compactness, survivability, and precision terminal performance. One-way attack drones trade some of that performance for endurance, lower cost, and quantity. Between those categories is a growing family of weapons using simple airframes, modular warheads, autonomous navigation, launcher-based deployment, and software-defined mission planning.

IN Defence recently covered Rheinmetall and Destinus moving into European cruise missile production, a programme driven by Europe’s renewed need for deep-strike capacity and domestic production. Kuzgun points to the same demand from a lower-cost direction. Armed forces want weapons that can reach beyond artillery range without consuming scarce high-end missiles for every target.

Export demand could be strong. Many countries cannot acquire advanced Western cruise missiles in the quantities they want, either because of cost, export controls, delivery timelines, or political conditions. Turkish unmanned and missile systems have already found customers that value rapid delivery, flexible integration, and a wider package of training and support. A long-range loitering munition could appeal to those same customers, especially where existing Turkish platforms, sensors, or command systems are already in service.

Production credibility will define the market. Buyers will ask how many systems can be built per month, how much of the component chain is domestic or sanction-resistant, how warheads are certified, how the system performs under electronic attack, and whether payloads or guidance packages can be adapted without redesigning the airframe. Those questions will separate mature industrial products from exhibition systems.

Kuzgun places STM inside a fast-moving category where affordability, range, and manufacturability carry as much weight as top-end performance. As deep-strike demand grows, the companies that can deliver repeatable, electronically resilient, and safely integrated loitering munitions at scale will shape a market that now sits firmly between drone production and missile manufacturing.
