ASELSAN’s IDENTIFFY Mode 5/S delivers secure, encrypted identification with sovereign crypto technology, ensuring trusted friend-or-foe recognition across air, land, and naval platforms for the future of air defense.
Modern battlefields demand not only firepower but also absolute certainty in identification. Identification Friend or Foe (IFF) systems are the safeguard that reduces friendly fire incidents and ensures coordinated mission success. For more than two decades, ASELSAN has been one of the leading forces in the development of Identification Friend or Foe (IFF) technologies, delivering mission-critical solutions that reduce the risk of friendly fire and ensure operational success. Trusted across land, air, and naval platforms, ASELSAN’s IFF systems have become an essential element of modern air defense architectures, enabling allies to operate with confidence in today’s contested environments.
Through its IDENTIFFY family, ASELSAN offers a complete range of solutions including long-range and short/medium-range interrogators, combined interrogator/transponder units, man-portable systems, and naval cabinet configurations. All systems are fully compliant with NATO STANAG 4193 Edition 3 and support Modes 1, 2, 3/A, C, S, and encrypted Mode 5 (Levels 1 and 2).
At the heart of this capability is the Mode 5 waveform, which represents the latest standard in secure identification. Mode 5 introduces advanced modulation and robust cryptographic techniques that significantly enhance the resilience of IFF systems compared to legacy modes. By employing spread spectrum transmission, Mode 5 enables encrypted data exchanges to be carried over existing ATC frequencies without causing interference, ensuring smooth interoperability with civilian air traffic systems. Unlike earlier modes, Mode 5 provides two levels of encryption: Level 1 for basic secure identification and Level 2 for extended encrypted data exchange, including altitude, position, and mission-specific information. These enhancements deliver a much higher probability of correct identification, even in dense or contested electronic environments, while also reducing vulnerability to spoofing or deceptive signals.
A cornerstone of ASELSAN’s leadership in this domain is its development of the M5K-II Mode 5 crypto applique, an indigenous encryption module that makes Türkiye one of the very few nations with sovereign Mode 5 crypto capability. Fully compatible with all IDENTIFFY devices, the applique secures both interrogations and responses, ensuring trusted communication between platforms and safeguarding the integrity of critical air defense operations.
Beyond encryption, ASELSAN provides a wide spectrum of technical configurations, including mechanically rotating and electronically scanned antennas, standalone systems for mobile operations, and cabinet-based solutions tailored for naval applications. This versatility ensures interoperability across diverse missions while maintaining the same core advantages: resilience against jamming, seamless integration with existing radars and sensors, and continuous monitoring through built-in test functions.
By combining sovereign cryptography, advanced digital architectures, and a broad portfolio of platform-ready solutions, ASELSAN’s IDENTIFFY IFF Mode 5/S Systems deliver a trusted shield for modern air defense. In a world where seconds define outcomes, ASELSAN ensures that every platform is identified securely, every mission is executed with confidence, and the skies remain safe for allies.
