Introduction The Naval Air Systems Command (NAVAIR), Program Executive Office for Unmanned Aviation and Strike Weapons (PEO U&W), Navy and Marine Corps Small Tactical Unmanned Aircraft Systems Program Office (PMA-263) at Patuxent River, MD is seeking industry input to identify potential solutions for a Medium Range Tactical (MRT) UAS for use by the United States Marine Corps Expeditionary Forces. The desired Medium Range Tactical (MRT) Unmanned Aircraft System (UAS) should be capable of providing Reconnaissance, Surveillance, and Target Acquisition (RSTA) during day and night operations across a variety of operational environments. The system should be ruggedized, robust, and rapidly deployable, delivered ready for operational use with minimal logistics, training, and sustainment burden. It should support mission planning, real-time intelligence collection, and enhanced situational awareness for tactical units, and operate independently or as part of a secure, collaborative network. The system should support operations including, but not limited to, RSTA, patrolling, security and force protection, convoy operations, and military operations in urban terrain (MOUT), and be capable of operating in austere locations, across diverse global climates and weather conditions, during day and night operations, and within degraded, denied, intermittent, and limited (DDIL) radio-frequency environments. Solutions capable of carrying modular payloads and a variety of sensors, including the provision of real-time Full Motion Video (FMV) via high-resolution electro-optical (EO) and/or infrared (IR) sensors, are of particular interest. The Air Vehicle (AV) should be capable of operating from stationary and mobile platforms, including amphibious ships and expeditionary advanced bases. Vertical Takeoff and Landing (VTOL) solutions, including fixed-wing VTOL (FW-VTOL) and multirotor VTOL configurations, are of interest. The AV should support autonomous or manual launch and recovery within designated or confined areas, with recovery methods that minimize system damage and enable rapid mission turnaround. The Ground Control Station (GCS) should be man-portable and either provide the necessary equipment to monitor sensor position and status, control AV movement, and display video, or be interoperable with existing common control systems available for U.S. Government procurement. The system should be designed for integration into tactical networks and support secure data sharing with other platforms and command elements. All mission data, including video and mission products, should be securely stored on the GCS and/or the AV using removable storage media. Responses to this Sources Sought Notice may be used to inform future acquisition planning and procurement decisions. Therefore, proposed UAS solutions must be compliant with applicable National Defense Authorization Act (NDAA) requirements, including but not limited to NDAA FY2020 Section 848, NDAA FY2023 Section 817, NDAA FY2019 Section 889, and the American Security Drone Act of 2023 (FY2024 NDAA, Public Law 118-31, Division A, Title XVIII, Subtitle B, Section 1821), or must clearly describe a credible, time-bound path to compliance, including identification of key dependencies, underlying assumptions, and anticipated timelines for achieving compliance. To support transparency and traceability of NDAA compliance, respondents may, at their discretion, leverage the Navy’s Small UAS Reusable Architecture (SRA) framework to document system components, supply chain attributes, and applicable security controls. The SRA provides government-backed tools and self-assessment mechanisms that enable vendors to independently evaluate alignment with DoD-approved benchmarks and facilitate review of compliance artifacts during market research activities. Additional information is available from the SRA Portal at: https://sra.navair.navy.mil The SRA website is Public Key Infrastructure (PKI) enabled, restricting access to those users who possess either a Department of Defense (DoD) Common Access Card (CAC) or DoD External Certificate Authority (ECA) certificate. Additional information – including instructions for obtaining an ECA certificate – is available at https://www.cyber.mil/eca. Accordingly, access to the SRA website may be limited for some respondents. Use of the SRA framework and associated tools is not required for response to this RFI and is provided for general awareness and informational purposes only. 2.
