Lockheed Martin announced on October 28, 2026, the successful flight-test demonstration of real-time in-flight retargeting for the Guided Multiple Launch Rocket System (GMLRS). Fired from an M142 High Mobility Artillery Rocket System (HIMARS) launcher at White Sands Missile Range, New Mexico, the GMLRS rocket received mid-course trajectory updates while airborne and successfully destroyed a moving target.
The test—conducted via internal research and development (IRAD) funding—bypasses the legacy operational constraint of GMLRS rockets relying strictly on fixed pre-launch GPS/INS target coordinates. By integrating Lockheed Martin’s Strigo datalink package and Remote Interceptor Guidance-360 (RIG-360) system, the trial establishes dynamic targeting capabilities against mobile threats across high-intensity contested battlefields.
TECHNICAL SPECIFICATIONS: GMLRS DYNAMIC RETARGETING & DATALINK INTEGRATION
System Classification, Launch Architecture & Datalink Integration
⚡ OEM & Lead Integrator: Lockheed Martin Missiles and Fire Control (Grand Prairie, Texas)
⚡ Host Launch Platform: M142 High Mobility Artillery Rocket System (HIMARS) / M270A2 Multiple Launch Rocket System (MLRS)
⚡ Test Location: White Sands Missile Range (WSMR), New Mexico
⚡ Integrated Datalink Framework:
• Strigo Airborne/Surface Datalink: Multi-node RF communications package transmitting continuous coordinate adjustments directly to the missile airframe
• Remote Interceptor Guidance-360 (RIG-360): Uplink/downlink command-and-control antenna terminal engineered to interface with integrated air and missile defense (IAMD) sensor networks and tactical fire direction nodes
⚡ Operational Ordnance Baseline: Standard GMLRS Unitary (M31 variant) / Alternative Warhead (M30A1/A2) 
Kinematics, Guidance Mechanics & Engagement Profile
💥 Flight Profile & Target Updating: Missile launches along an initial ballistic arc based on baseline GPS/INS inputs; mid-course sensors detect target repositioning and transmit updated coordinates via RIG-360/Strigo to adjust canard control surfaces mid-flight
💥 Kinematic Performance: Mach 3+ cruise velocity; operational range of 70 km to 84+ km (standard GMLRS) and 150 km (Extended Range GMLRS / ER GMLRS)
💥 Guidance & Seeker Configuration: Dual-mode mid-course GPS/INS updating combined with real-time target data feed; removes dependence on stationary coordinate sets
💥 Modular Scaling Roadmap: Datalink architecture designed for direct integration across ER GMLRS and the Precision Strike Missile (PrSM) Inc 1/Inc 2 platforms
TIMES OF DEFENCE ASSESSMENT
The dynamic in-flight retargeting demonstration of a HIMARS-launched GMLRS represents a major technological leap for deep-strike precision field artillery.
From an artillery doctrine and aerospace systems integration perspective, this milestone highlights three core operational insights:
1. **Neutralizing Mobile High-Value Relocatable Targets**: Historically, GMLRS has served as a precision “counter-battery and static target” weapon, vulnerable to target relocation during the missile’s flight time. Enabling mid-course target updates allows ground forces to hit mobile air defense radars, moving command vehicles, and shifting armor formations at stand-off ranges.
2. **Sensor-to-Shooter Networked Fires Synergy**: Combining RIG-360 with the Strigo datalink bridges the gap between offboard ISR assets (such as HADES spy planes, MQ-9 Reapers, or forward FPV drones) and airborne munitions. Forward sensors can track a target altering its movement profile and push real-time telemetry to the missile via RIG-360, eliminating the delay of relaying coordinates back through ground command posts.
3. **Cross-Fleet Retrofit Potential without Missile Redesign**: Because the test leveraged internal Lockheed Martin funding using standard GMLRS airframes, the datalink integration provides a cost-effective upgrade path. Applying this software and RF receiver package across existing GMLRS stockpiles, ER GMLRS, and long-range PrSM effectors gives commanders dynamic targeting options across all operational strike ranges.
