The TRG-122 represents the evolution of conventional 122 mm multiple launch rocket system munitions into a precision-strike capability. While traditional 122 mm rockets are primarily used for area suppression, the TRG-122 introduces guided flight correction, transforming the role from saturation fire to precision engagement.

Operational Purpose and Role

The primary mission of the TRG-122 is to provide precise, rapid, and cost-effective fire support at the tactical level. It is particularly effective against:

• Enemy artillery and MLRS batteries
• Short- and medium-range air defense systems
• Radar and sensor positions
• Command, control, and communication centers
• Logistics facilities and troop assembly areas

By combining rapid launch capability with guided accuracy, the system supports maneuver brigades operating in dynamic and time-sensitive battlefield environments.

Doctrine and Concept of Use

The TRG-122 is designed for integration with existing 122 mm multiple launch rocket systems in service. This allows armed forces to upgrade firepower precision without replacing their launcher infrastructure.

Doctrinally, it supports:

• Counter-battery operations
• Precision strikes in tactical depth
• Suppression of high-value targets
• Immediate fire support for advancing units

Before launch, target coordinates are uploaded into the fire control system. During flight, the rocket performs trajectory corrections using its INS and GNSS-supported guidance unit. In GNSS-denied environments, the inertial navigation system allows continued guidance with reduced but sustained accuracy.

System Architecture

The TRG-122 consists of:

• Rocket motor section (composite solid propellant)
• Guidance and control unit (INS + GNSS support)
• Electromechanical aerodynamic control surfaces
• High-explosive steel ball fragmentation warhead

Unlike purely ballistic rockets, the TRG-122 actively corrects its trajectory during flight using control surfaces actuated by electromechanical systems.

Accuracy and Engagement Process

The publicly stated Circular Error Probable (CEP) is ≤ 20 meters. This level of precision significantly enhances effectiveness against coordinate-defined targets.

The engagement sequence typically includes:

• Target detection and coordinate determination
• Data transfer to the launcher fire control system
• Rocket launch
• Mid-course trajectory correction via INS/GNSS
• Terminal phase impact and detonation

The 13.5 kg fragmentation warhead provides an effective lethal radius of at least 40 meters.

Survivability and Modern Threat Environment

Advantages:

• High precision compared to unguided 122 mm rockets
• Reduced collateral damage
• Compatibility with existing launcher systems
• Rapid deployment and short preparation time

Limitations:

• Maximum range of 30 km limits operational depth compared to longer-range guided rockets
• Ballistic trajectory makes it potentially vulnerable to advanced air defense systems
• Limited penetration capability against heavily armored targets
