The Department of Defense, specifically the Navy, is seeking innovative solutions for a Direct to Phase II Small Business Innovation Research (SBIR) opportunity focused on developing guided wave technology for tank leak detection. The primary objective is to create a portable, user-friendly Non-Destructive Testing and Evaluation (NDT&E) technology that can efficiently detect and locate leaks in shipboard tanks without the need for opening them, thereby reducing inspection and repair man-hours. This technology is crucial for maintaining the integrity of built-in tanks on naval vessels, which are susceptible to leaks due to various factors, and is essential for timely ship repairs and operational readiness. Interested parties should prepare to submit their feasibility documentation by the application due date of February 5, 2025, with the opportunity being officially open for applications starting January 8, 2025.
