U.S. Marines Field Tempest Counter-UAS Vehicle for Mobile Protection Against Drone Threats

Army Recognition

The U.S. Marine Corps is fielding ten V2X Tempest counter-unmanned aerial system (C-UAS) vehicles under a $19.06 million contract to protect maneuver units against Class 2 and Class 3 drone threats. This procurement introduces a highly mobile, missile-based kinetic defense layer designed to operate alongside existing air-defense networks.

Integrating these systems into the wider Marine C-UAS architecture bridges the gap between heavy air-defense assets and light electronic warfare capabilities. The Tempest vehicle integrates a Can-Am 4x4 all-terrain chassis with two AGM-114L Longbow Hellfire missiles and a RADA RPS-42 radar. This configuration prioritizes rapid off-road mobility over heavy armor. Survivability depends on speed. By utilizing active millimeter-wave radar guidance, crews can launch missiles and immediately relocate to avoid counter-battery fire. The system relies on external targeting networks to compensate for its single-panel radar limitation, ensuring distributed units can engage priority targets while conserving ammunition for saturation attacks.

Comment

The integration of the AGM-114L Longbow Hellfire onto the lightweight Can-Am 4x4 platform represents a shift toward highly distributed, shoot-and-scoot kinetic air defence. By utilising an active millimeter-wave radar seeker, the Tempest platform allows Marine crews to fire and immediately egress, minimising exposure to counter-battery fire. However, the reliance on a single-panel RADA RPS-42 radar restricts organic search sectors, making the vehicle dependent on external targeting feeds from the wider MADIS network. This dependency exposes a vulnerability if tactical VHF/UHF communications are disrupted by adversary electronic warfare.

Consequently, the operational utility of these ten Tempest platforms hinges entirely on the resilience of the Marine Corps' cooperative engagement networks. If the primary data links fail under electronic attack, Tempest crews will be forced to rely on visual acquisition or highly restricted organic radar sectors, severely degrading their early-warning timeline. This vulnerability will likely drive future Marine procurement toward integrating passive electro-optical sensors onto the Can-Am chassis to preserve the platform's low-signature profile.

Strategic Question for Discussion

How does the loss of external targeting data links affect the tactical viability of the Tempest platform, given that its single-panel RADA RPS-42 radar cannot provide 360-degree coverage for the AGM-114L Longbow Hellfire?

The pattern of modern peer conflict suggests that losing external data links would force Tempest crews to orient their single-panel RADA RPS-42 radar toward expected threat vectors, creating blind spots that agile Class 3 drones can exploit. Without network-derived early warning, the engagement envelope of the AGM-114L Longbow Hellfire would contract significantly, reducing the system to a reactive, short-range point defence asset. Consequently, the platform's survivability would degrade as crews are forced to emit radar signals continuously rather than operating in a passive, low-signature mode.
