The Department of Defense, specifically the Navy, is seeking innovative small businesses to develop a Direct to Phase II prototype for the F7-Wideband Acoustic Receiver and Source (F7-WARS) Sonobuoy. The objective is to create an advanced air-deployable sensor system capable of characterizing the acoustic ocean environment in the Low Frequency range, addressing current limitations in existing technologies for anti-submarine warfare (ASW) measurements. This system is critical for pre-mission planning, environmental analysis, and marine mammal mitigation during naval operations, ensuring effective intelligence gathering across varied oceanic environments. Interested parties must submit their proposals by June 12, 2024, with further details available on the official SBIR website.
