Turkish naval solutions provider STM unveiled the final design of the National Fast Attack Craft (FAC) during the IDEF 2025 defense industry exhibition, held in Istanbul from July 22 to 27, 2025.
The National FAC project aims to build modern FACs to replace the aging Dogan- and Ruzgar-class FACs that have been in service with the Turkish Navy for decades. The contract for the design phase of the FACs was signed between SSB and STM on August 31, 2020. After an extensive conceptual and detailed design work in collaboration with the Turkish Navy, STM unveiled the mockup of the final design at IDEF 2025 defence industry fair.
At first glance, the design appears to be an enhanced evolution of the KILIร II-class Fast Attack Craft (FAC), a proven platform that has served the Turkish Navy for over two decades. However, the new National FAC stands out with its significantly larger size and displacement, positioning it between traditional FACs and light corvettes. With a displacement exceeding 700 tons and a length approximately 10 meters longer than the current FACs in service, the vessel represents a new generation of high-endurance, high-performance attack craft tailored for littoral warfare.
While earlier design concepts for the National Fast Attack Craft (FAC) envisioned a hybrid propulsion system combining gas turbines and diesel engines, the final model unveiled at IDEF 2025 features a quad-diesel engine configuration, delivering a top speed of 39+ knots. In a significant design choice, STM opted for four waterjets instead of the conventional shaft-and-propeller transmission system. This configuration enhances maneuverability and operational efficiency, particularly in shallow and confined waters, making the vessel well-suited for littoral combat missions.
The National Fast Attack Craft will accommodate up to 36 personnel, a notable reduction compared to the 45โ50 crew members required to operate the current FACs in service with the Turkish Navy. This significant decrease in crew size highlights the vesselโs advanced automation and integrated monitoring systems, which reducing manpower requirements.
Naval News has learned that the National FAC will be built with a high level of indigenization, with nearly all of its sensors and weapon systems supplied by Turkish defense companies. The vesselโs main punch capability will come from Roketsanโs ATMACA surface-to-surface missiles, MKEโs 76 mm DENฤฐZHAN naval gun will serve as the shipโs main gun. For close-in defense, the FAC will be equipped with a Point Defense Missile System (PDMS)โeither Roketsanโs LEVENT or Aselsanโs GรKSUR. The ship will also be fitted with two 12.7 mm remote weapon stations.
Most of the vesselโs sensor suite will be supplied by Aselsan, further reinforcing the National FACโs high level of indigenous content. The ship is expected to feature either the CENK-300 or CENK-350 AESA radar, for air and surface surveillance. Other key Aselsan systems include the AKREP fire control radar, the PIRI KATS electro-optical surveillance and targeting system, a navigational radar, and ARES family of electronic support (ES) and electronic countermeasure (ECM) systems. All of these sensors and subsystems will be integrated into HAVELSANโs ADVENT combat management system, enabling network-centric warfare capabilities.
According to officials at the STM booth, construction of the first National Fast Attack Craft (FAC) is already underway, having commenced with a steel-cutting ceremony. While the company targets 2028 for the beginning of sea trials, the official delivery timeline has not yet been disclosed. Under the current program, STM will deliver 10 FACs to the Turkish Navy, though officials noted that additional units may be considered in the future based on the evolving operational requirements of the Navy.
