Mobile Non-Line-of-Sight Missile Integration on Infantry Squad Vehicles

Modern light infantry formations often lack organic indirect-fire capabilities capable of neutralizing armored vehicles and defensive positions beyond direct line-of-sight without relying on external close air support or divisional artillery. To resolve this tactical fire-support gap, Lockheed Martin demonstrated the Spike Non-Line-of-Sight (NLOS) precision missile system integrated onto an Infantry Squad Vehicle – Utility variant (ISV-U), validating mobile long-range strike capabilities directly operated by infantry personnel.

Operational Validation and Ground-Platform Integration
The live-fire demonstration took place across three days at Dugway Proving Grounds in Utah, executing 17 precision engagements against simulated operational targets placed at varied combat ranges. U.S. Army infantry soldiers conducted the majority of the launches from the ISV-U platform, marking the first time the missile system was fired from this specific lightweight utility vehicle.

The demonstration advances the U.S. Army Mobile-Long-Range Precision-Strike Missile (M-LRPSM) directed requirement. Participating soldiers belonged to Transformation-in-Contact (TIC) units, structured to evaluate developmental hardware in tactical field settings. Feedback from these operators will guide ongoing system refinements ahead of Phase 3 testing, which encompasses final prototype deliveries and initial operational production.

System Architecture and Tactical Guidance Mechanics
Spike NLOS is an electro-optical and imaging infrared (EO/IIR) guided missile engineered to engage targets at standoff ranges up to 32 kilometers from ground launchers. The munition utilizes an encrypted bi-directional radio frequency data link that relays real-time seeker video back to the operator console while transmitting steering commands back to the missile.

This technical configuration enables a man-in-the-loop operational profile. The operator can track moving targets, adjust the terminal impact point to counter countermeasures or obscurement, reassign targeting mid-flight, or abort the engagement entirely. By integrating this launcher mechanism onto the ISV-U, light forces maintain indirect fire reach without relying on satellite positioning, providing resilience in environments where radio frequencies or satellite navigation signals face electronic jamming.

Tactical Workflow and Infantry Usability
Deploying long-range missile systems onto light tactical vehicles traditionally presents operational hurdles in user training and vehicle stabilization during rocket motor ignition. During the Utah trials, infantry soldiers completed system training and executed live-fire missions within a single week.

Integrating non-line-of-sight precision strike systems directly onto mobile infantry platforms compresses the sensor-to-shooter cycle. For Mobile Brigade Combat Teams, mounting organic precision strike capabilities on lightweight, air-transportable vehicles eliminates the delay of requesting joint air or heavy artillery fires when encountering reinforced enemy positions.

Engineering Leadership Perspective
The tactical integration of the platform was outlined by program leadership following the field tests.

"The live-fire data and soldier feedback gathered here will support the shaping of the final M-LRPSM requirements and accelerate the fielding of a long-range precision strike capability," said Casey Walsh, program director of Lockheed Martin Multi-Domain Missile Systems.

Additional Context:
This section details technical specifications and competitive benchmarking not included in the original product announcement.

Traditional anti-tank guided missiles used by light infantry units, such as the BGM-71 TOW and FGM-148 Javelin, operate primarily within direct visual line-of-sight, constraining ground vehicle engagement ranges to between 2.5 and 4.5 kilometers. While loitering munitions offer beyond-line-of-sight capability, they typically possess smaller warheads and slower transit speeds than solid-propellant rocket munitions.

Spike NLOS provides a standoff range of 32 kilometers in ground-launched configurations and weighs approximately 70 kilograms per munition round. The missile accommodates multiple warhead configurations, including high-explosive anti-tank (HEAT) and blast-fragmentation payloads designed against armored vehicles and fortified structures.

Mounting the system onto the ISV-U—a tactical platform developed from the commercial Chevrolet Colorado ZR2 chassis—requires careful engineering management of payload mass, center of gravity, and launch recoil forces. Similar light missile integration initiatives in allied nations include the installation of Spike ER2 and Spike NLOS on the Oshkosh JLTV and Milrem THeMIS unmanned ground vehicles, reflecting a broader NATO transition toward decentralized, mobile precision artillery for distributed operations.
