Forterra MESA UGV Mounts 10-Bay HAL10 Launcher with VESPID Mk 1 Counter-Drone Interceptors.

Forterra has unveiled a mobile counter-drone system that turns its MESA autonomous ground vehicle into a forward air-defense node, combining the 10-cell ISS Aerospace HAL10 launcher with CHAOS Industries’ VESPID Mk 1 interceptor at the AUSA Annual Meeting in Washington from 12–14 October 2026. With a 2,000 lb payload capacity and autonomous mobility in complex or GPS-denied environments, the configuration could allow dispersed forces to move counter-UAS interceptors closer to the fight, rapidly reposition air-defense coverage, and engage drone threats while keeping personnel away from exposed launch positions.

A new mobile counter-UAS configuration unveiled in Washington brings autonomous ground mobility, a multi-round launcher and a low-cost aerial interceptor together on a single unmanned platform. Displayed during the AUSA Annual Meeting & Exposition on October 12, 2026, the configuration combines Forterra’s MESA autonomous ground vehicle, ISS Aerospace’s HAL10 launcher and CHAOS Industries’ VESPID Mk 1 interceptor. Based on technical information released by the three companies, the integration is particularly significant because it illustrates how modular autonomous vehicles could become distributed air-defense nodes able to move alongside maneuver forces rather than remain tied to fixed defensive positions.

At the foundation of the configuration is Forterra’s MESA, a modular autonomous vehicle designed to extend military capabilities into what the company describes as the last tactical mile. MESA is built on a factory-modified Polaris Ranger XD 1500 and integrates Forterra’s AutoDrive autonomy technology with its Vektor mission modules, bringing together mobility, computing, communications and sensing at the tactical edge. Its flat-deck architecture incorporates L-Track mounting and can accommodate payloads of up to 2,000 lb, creating considerable flexibility for mission-specific equipment. Forterra says AutoDrive provides autonomous navigation in complex and GPS-denied environments, while the platform’s open architecture is intended to facilitate integration with external sensors, command systems and specialized payloads. In this configuration, that modular philosophy is being applied directly to the counter-drone mission.

Installed on the MESA is ISS Aerospace’s HAL10 Hybrid Air-Systems Launcher, which forms the critical bridge between the autonomous carrier and the airborne interceptors. HAL10 is a modular 10-bay cassette launcher in a 5×2 arrangement, engineered to store, manage and deploy multiple small unmanned aircraft or launched effects. ISS Aerospace specifically identifies counter-UAS and force-protection missions among the launcher’s applications and has designed HAL10 as a platform-agnostic system capable of operating from fixed sites, forward installations or mobile vehicles. More than simply providing ten launch tubes, the system gives MESA the ability to carry a magazine of ready-to-deploy aerial effectors, potentially allowing an autonomous ground platform to reposition its counter-UAS capacity as the protected force moves.

The effector completing the configuration is CHAOS Industries’ VESPID Mk 1, a tube-launched interceptor developed specifically for high-density counter-UAS applications. CHAOS confirms that the Mk 1 is compatible with the ISS Aerospace HAL10, with the interceptor making its first public display aboard the Forterra MESA at the 2026 AUSA event. Designed for engagement of Group 1–3 UAVs and one-way attack threats, VESPID Mk 1 has a stated range exceeding 10 km, weighs less than 12 lb and cruises at approximately 150 meters per second, with CHAOS claiming a time to target of under 100 seconds. The interceptor uses an electric ducted-fan propulsion system and modified commercial-off-the-shelf architecture intended to reduce cost and simplify high-volume production compared with traditional missile propulsion. Mid-course guidance can be provided by CHAOS radars or an external command-and-control system, while a long-wave infrared seeker with AI-enabled processing supports terminal acquisition and guidance without dependence on GPS.

The importance of the display lies less in any individual component than in the way the three technologies have been assembled into a mobile counter-UAS architecture. Forterra supplies autonomous mobility and the mission-platform layer; ISS Aerospace provides the multi-round launch infrastructure; and CHAOS Industries supplies the interceptor, while Polaris Government and Defense provides the underlying Ranger XD 1500 vehicle foundation used for MESA. The configuration also represents a logical expansion of cooperation already underway between Forterra and CHAOS. The two companies announced a strategic counter-UAS partnership in October 2025 after integrating CHAOS sensing technology with Forterra-powered autonomous ground vehicles. The addition of HAL10 and VESPID Mk 1 moves the concept beyond mobile sensing alone and illustrates how autonomous mobility could also carry the effector side of the counter-UAS kill chain.

That approach is increasingly relevant as military forces confront inexpensive drones and one-way attack systems in quantities that can challenge both the magazine depth and economics of conventional air defense. A mobile platform carrying multiple lower-cost interceptors could, in principle, distribute defensive capacity across dispersed formations, reposition according to the tactical situation and reduce the need to place crews directly alongside the launcher. It also reflects the broader emphasis at AUSA, the Association of the United States Army Annual Meeting & Exposition, one of North America’s principal land-power exhibitions and professional forums. Held in Washington from October 12 to 14, the 2026 event brings together U.S. and international military leaders, government officials and defense companies, making it an important venue for technologies addressing emerging Army requirements in autonomy, unmanned systems and counter-UAS operations.

The MESA-HAL10-VESPID Mk 1 configuration ultimately demonstrates how several specialized defense technologies can be combined to create a capability greater than the sum of its individual components. Forterra contributes the autonomous carrier, ISS Aerospace the scalable launch architecture, CHAOS Industries the counter-drone interceptor, and Polaris the proven vehicle base, creating a modular pathway toward mobile and potentially distributed air defense. Its full military value will depend on factors that have not yet been publicly established for this specific configuration, including integrated detection-to-engagement testing, reload procedures, engagement performance while deployed from MESA and eventual customer adoption. What is already clear from the Washington display, however, is the direction of development: instead of relying exclusively on crewed and highly specialized air-defense vehicles, future forces could increasingly distribute affordable counter-drone effectors across autonomous platforms able to move with the formations they are designed to protect.
