A fuze is the subsystem that determines when, how, and under which conditions a munition detonates. In modern warfare, fuzes are no longer simple impact triggers; they are intelligent, multi-layered safety and activation mechanisms capable of processing parameters such as distance-to-target, acceleration, rotation rate, laser reflection, or proximity data.

The Roketsan Fuze Technology Center develops and qualifies fuze systems for various calibers and mission profiles. The portfolio includes:

• Proximity fuzes for long-range 122 mm rockets
• Electromechanical fuzes for CİRİT, L-UMTAS, UMTAS, and OMTAS missile families
• Electromechanical fuzes for MAM-L and MAM-C UAV munitions
• Electromechanical fuzes for DSH rockets
• Proximity fuzes for TRG-230 missile systems
• Verification and qualification support for KARAOK missile fuzes
• Electronic fuze assemblies for loitering munitions and strike UAVs
• Development activities for laser-guided mini missile fuzes
• TST-101 fuze development, validation, and serial production preparation

Operational Purpose and Role

The fuze directly defines the munition’s lethality profile and engagement mode. It enables:

• Point detonation upon impact
• Delayed detonation for armored targets
• Proximity airburst for area suppression
• Controlled detonation for urban warfare scenarios

For example, proximity fuzes allow airburst capability, increasing fragmentation efficiency against personnel, drones, or soft targets. Electromechanical fuzes provide high reliability and safe arming for guided missiles.

Doctrine and Concept of Use

Modern combat environments require adaptable detonation logic. Roketsan fuzes support:

• Area denial and airburst fragmentation
• Anti-armor delayed penetration effects
• Counter-UAV engagements
• Precision-guided strike operations
• Loitering munition impact optimization

Proximity fuzes are particularly critical in air defense and anti-drone scenarios. Electromechanical fuzes are widely used in guided missile systems where safe arming distance and controlled detonation are essential.

System Architecture

Typical Roketsan fuze architecture includes:

• Sensor module (RF proximity sensor or inertial/mechanical trigger)
• Safe & Arm Device (SAD)
• Power management unit
• Electronic control board
• Initiation and detonation chain

Proximity fuzes are generally RF-based systems utilizing radar-like sensing for distance measurement. Frequency band details are not publicly disclosed.

Survivability and Safety Architecture

Designed according to MIL-STD-1316 and STANAG-4187 standards, Roketsan fuzes incorporate:

• Multi-layer safety barriers
• Mechanical and electronic safeties
• Independent arming logic
• Transportation and storage safety compliance

They remain fully safe during handling, storage, and transport, only arming after defined launch and flight conditions are met.

Test and Qualification Infrastructure

The Fuze Technology Center includes:

• Environmental conditioning chambers
• Anechoic chamber (RF testing)
• Jolt and jumble test systems
• 1.5 m and 12 m drop test facilities
• ESD test equipment
• HALT/HASS systems
• Detonation test facilities
• Centrifuge systems for high-G testing
• Vibration test equipment
• X-ray and endoscopic inspection systems

Testing is conducted in accordance with MIL-STD-331 and MIL-STD-810 standards.
