The United States Army has issued a sources sought notice (SSN) for vendors interested in providing potential international field services and support to the Program Executive Office Missiles and Space Counter-Unmanned Aircraft System (C-UAS) Product Office.
“Modern C-UAS operations rely on a System of Systems (SoS) approach, integrating multiple sensors, effectors and command-and-control (C2) platforms to detect, track and defeat unmanned aerial threats,” the SSN states. “These systems are deployed in complex, multinational environments where interoperability, agility and technical resilience are paramount. To sustain these capabilities, the government requires highly skilled Field Service Representatives (FSRs) with expertise in SoS integration, sustainment, and operational support across diverse international theaters.”
Anticipated requirements include:
- Technical Field Support: Deployment of SoS-qualified FSRs to international locations for on-site support where personnel must possess technical fluency across Radio Frequency (RF) detection, radar, Electro-Optical/Infrared (EO/IR) tracking, kinetic and non-kinetic defeat mechanisms, and C2 integration. On-site system sustainment is expected to include diagnostics, repair, calibration and performance optimisation of interconnected subsystems. Field support will also include interoperability engineering for integration with host nation and allied networks, ensuring seamless data exchange and coordinated response.
- Training and Capacity Building: Delivery of operator and maintainer training with hands-on instruction tailored to host nation personnel, covering system operation, maintenance and tactical employment. Train-the-Trainer programmes will be designed to build indigenous capacity and reduce long-term reliance on US personnel.
- Logistics and Lifecycle Support: Sustainment planning will include forecasting and provisioning of spare parts, consumables and mission-critical components. The vendor must provide in-country support for coordination of international shipments, customs clearance, and adherence to ITAR and host nation regulations. Field-level support will also be provided for software and firmware updates, patches and configuration control across integrated systems.
- Operational Coordination and Advisement: Principle in-country programme representative supporting host-country military command and serving as the liaison to the US country team and combatant command units. Assist, where necessary, in mission planning and post-mission reviews.
Responses are invited by November 21.
