The Department of Defense, specifically the U.S. Navy, is seeking small businesses to develop and demonstrate an advanced air-deployable F0-Wideband Acoustic Receiver and Source (F0-WARS) Sonobuoy under the SBIR program. The objective is to create a sonobuoy capable of collecting active target strength data in the F0 frequency range, enhancing anti-submarine warfare (ASW) capabilities with improved directional information and echolocation features in three-dimensional space. This technology is crucial for gathering acoustic information on enemy targets, thereby significantly enhancing operational effectiveness in both shallow and deep-water environments. Interested parties must submit Phase I feasibility documentation by May 21, 2025, to validate their capability to meet the outlined requirements, with further details available at the provided source link.
