Türkiye's domestically developed GOKSUR IIR infrared seeker-headed missile successfully struck a low-altitude target flying close to sea level in a test launch from the GOKSUR 100-N Vertical Launch System (VLS), defense officials announced late Monday.

The missile, developed by Aselsan and TUBITAK SAGE, hit a high-speed target at a range exceeding 11 kilometers (6.8 miles) in tests conducted in Sinop, marking the first time a Turkish-made missile has struck a near-sea-surface target with a direct hit.

Presidency of Defense Industries (SSB) head Haluk Gorgun said the successful test represents a game-changing air defense capability for naval platforms.

"Our national air defense architecture is developing with new capabilities," Gorgun said in a statement posted on social media.

"We have provided naval platforms with a game-changing air defense capability," he noted.

How GOKSUR IIR missile system works

The GOKSUR IIR missile uses a fire control system with mid-course guidance via data link to direct it toward targets.

The missile locks onto targets using its next-generation IIR seeker head before destroying them with direct hits.

The system is designed to provide point air defense for surface platforms, with high effectiveness against challenging targets such as sea-skimming anti-ship missiles and cruise missiles.

The missile can engage threats including cruise missiles, unmanned aerial vehicles and fighter aircraft flying close to the sea surface.

Three configurations of GOKSUR IIR for naval deployment

The GOKSUR Point Defense Missile System (PDMS) will serve the Turkish Navy in three different configurations.

These include the GOKSUR 100-N VLS Modular Vertical Launch System, the GOKSUR 100-N/StA all-in-one system capable of independent operations (Standalone Mission-Capable System), and the GOKSUR 100-N Combat Management Integrated System, which integrates with combat management systems.

The system features artificial intelligence-supported fire control and multiple engagement capability, providing advanced defense capabilities.

Enhanced effectiveness against low-altitude threats and uplink-downlink mid-course guidance capabilities via data link will enable the system to play a critical role in defending Türkiye's maritime zones.

Key features, capabilities of GOKSUR PDMS

  • 360-degree coverage: The system offers complete target destruction capability across 360 degrees, ensuring no blind spots in the defense perimeter.
  • Rapid reployment: With a short deployment time, the system can operate effectively under adverse sea conditions, making it ideal for fast-moving, unpredictable maritime environments.
  • Multi-target engagement: Equipped with an advanced fire control system powered by artificial intelligence, the GOKSUR 100-N can simultaneously engage multiple threats, providing enhanced protection against diverse and evolving threats.
  • Mid-course guidance: The missile's mid-course guidance capability allows for the interception of sophisticated anti-ship threats.
  • Enhanced missile capacity: The 20-missile configuration boosts operational flexibility, enabling the system to address multiple targets concurrently.
  • Long Range: With a 15 km range, the system provides extended defense coverage.
  • Target versatility: The GOKSUR 100-N is highly effective against sea-skimming anti-ship missiles, cruise missiles, UAVs, fighter jets, and helicopters, providing a comprehensive shield for naval platforms.
  • High kill probability: With its superior guidance and tracking systems, the GOKSUR 100-N offers a high probability of kill with a single shot.
  • Modular design: Its flexible architecture allows it to be tailored for various vessel types, enhancing integration and operational adaptability.
  • Integration flexibility: The system can function either standalone or integrated into a Combat Management System (CMS), providing versatile operational modes.

Development based on air-to-air missile

GOKSUR utilizes the GOKSUR IIR missile, developed by TUBITAK SAGE, for the air defense needs of naval platforms.

The missile was designed by adapting the BOZDOGAN air-to-air missile for naval platforms, with added features including two-way data link and vertical launch capability.

The data link-integrated derivative BOZDOGAN-DH missile can make mid-course updates with data from the ship's and GOKSUR's sensors and will orient toward targets in the terminal phase with an IIR seeker head.

According to Aselsan statements, the beyond-visual-range GOKDOGAN air-to-air missile can also be used in GOKSUR.

The first launch of the GOKSUR IIR missile was successfully conducted in February from the TCG Beykoz ship using the GOKSUR 100-N Vertical Launch System.
