What project 9999 buys

- FY 2025 Congressional add for security monitoring at maritime chokepoints will evaluate a network of passive seismic and hydroacoustic phased arrays to determine its effectiveness in detecting, classifying, localizing, and tracking hostile submarines and unmanned underwater vehicles (UUVs). This assessment should focus on the system's ability to counter covert threats posed to ballistic missile submarines (SSBNs) while transiting critical maritime chokepoints or during port visits. FY 2026 Congressional adds for the following efforts: - Navigation Research and Development Center (NRDC) Facility Modernization funding includes the upgrade and expansion of critical Warminster, PA facility. This modernization will expand the facility by providing state-of-art infrastructure to accelerate R&D, rapid prototyping, test and evaluation capabilities for autonomous, advanced, and strategic weapon systems. These capabilities are essential for Navy strategic objectives to support future strategic defense solutions, critical test capabilities, faster fielding of technologies to meet pacing threats, and modernize innovation and collaboration with Government and industry partners. These investments will foster innovation, attract a talented workforce, and ensure a long-term commitment to the strategic readiness. - Strategic Systems Supply Chain Management will bolster the Strategic Defense Industrial Base (SDIB), mitigate supply chain vulnerabilities, and accelerate the development of high-priority national security systems. This initiative will enhance industrial readiness by optimizing the Conventional Prompt Strike (CPS) transition to fielding, assessing vendor viability for the Sea-Launched Cruise Missile-Nuclear (SLCM-N), and investing in emerging propulsion and guidance technologies to maintain a decisive technological advantage. Foundational to this effort is enterprise-level analysis to support strategic sourcing, targeted workforce development, and key acquisition reforms that stabilize demand signals across the industrial base. The execution of these tasks is vital to reducing production risks for our most critical defense programs, ensuring the timely delivery of advanced capabilities to the warfighter, and maintaining our nation's strategic deterrent.
