The Department of Defense, specifically the U.S. Army, is seeking proposals for the Small Business Innovation Research (SBIR) program focused on developing an underwater sensing system for surf zone environments. The objective is to create a portable sensor capable of detecting bathymetry and underwater hazards in shallow, bubbly conditions, which is critical for safe maritime operations and logistics support in contested regions. This technology is particularly important for enhancing situational awareness during over-the-shore operations, where traditional sensing methods are hindered by environmental factors such as surf zone bubbles. Proposals for Phase I are due by August 20, 2025, with a funding amount of up to $250,000 for a six-month performance period. Interested parties can find more information and submit proposals through the official SBIR website.
