The S2MARTS OTA (Strategic & Spectrum Missions Advanced Resilient Trusted Systems) is one of the most active and strategically important Other Transaction Authority (OTA) acquisition vehicles used by the U.S. Navy and Department of Defense to accelerate dual-use innovation. Managed by the National Security Technology Accelerator (NSTXL), S2MARTS streamlines the prototyping and transition of emerging technologies without the long administrative timelines associated with FAR-based procurement or traditional Broad Agency Announcements. This OTA model allows companies, universities, nontraditional defense contractors, semiconductor innovators, and commercial engineering teams to rapidly design, prototype, demonstrate, refine, and transition technologies that are mission-critical to U.S. national security and industrial competitiveness. 

S2MARTS focuses heavily on microelectronics modernization, trusted hardware architectures, 5G and 6G communications, advanced sensing, electromagnetic spectrum dominance, mission-aware supply-chain assurance, cognitive EW, secure semiconductor manufacturing, radiation-tolerant materials, and resilient tactical networking. As global competition intensifies, the DoD requires rapid access to field-ready hardware that can be ruggedized for contested environments, deployed quickly, and scaled across naval, airborne, space, cyber, and expeditionary domains. S2MARTS was created to bypass the development bottlenecks that traditionally prevent the timely adoption of cutting-edge commercial or academic innovation. 

Solicitations often emphasize secure and trusted microelectronics, spectrum-adaptive hardware, RF superiority, next-generation tactical networks, device-level cybersecurity, industrial base resilience, and cross-domain situational awareness, as well as edge AI for threat detection, mission planning, autonomous sensor operation, RF analytics, and resilient communications. Projects may include prototype fabrication, ASIC or chiplet design, anti-tamper architectures, RF system ruggedization, secure manufacturing workflows, testing infrastructure, dual-use supply-chain analytics, and performance demonstrations with operational users. 

S2MARTS supports multidisciplinary teaming, encouraging collaboration between semiconductor engineers, RF hardware designers, materials scientists, autonomy specialists, cybersecurity experts, cloud architects, EW researchers, mission-command technologists, and academic labs. Evaluators prioritize technical feasibility, manufacturability, rapid demonstration potential, dual-use commercialization, ruggedization, export-controlled compliance, and clear transition planning. Many solicitations begin with a short technical white paper, significantly lowering the barrier to entry for new performers and enabling rapid evaluation cycles. 

As strategic competition expands and national supply-chain security becomes a top priority, the S2MARTS OTA plays an essential role in modernizing U.S. microelectronics, strengthening resilient semiconductor production, enhancing spectrum superiority, and enabling secure mission execution across tactical and industrial environments. This OTA mechanism is now one of the fastest routes for transitioning early-stage semiconductor and spectrum-relevant innovation into real-world defense adoption.
