Advanced Techniques for Enhanced Deep-Sea Object Detection and Localization for Towed Mine Countermeasures (MCM) Sonar

The U.S. Navy is seeking SBIR solutions to improve deep-sea object detection and localization for towed mine countermeasures sonar by extending sensor range for depth and distance. The work calls for innovative hardware, software, algorithms, or techniques that can optimize sonar performance without increasing tow-body size, weight, or power, and that remain compatible with current Navy systems. Proposals should address the target performance of at least 90% probability of detection while maintaining a false alarm rate of 0.1 per hour, with hardware constrained to the existing tow-body form factor and power limits; Phase II work may be classified and requires the ability to obtain and maintain a secret facility clearance and personnel clearances. Phase I is for concept development and feasibility, Phase II is for prototype development and evaluation with technical documentation and a live demonstration, and Phase III supports transition to Navy use and possible dual-use applications. The solicitation number is 26.BZ under topic DON26BZ02-NV048, and applications are due June 24, 2026 at 4:00 PM ET.
