Silencing with Acoustic Rainbow Emitters (SWARE)
SBIR Opportunity Analysis
USSOCOM, through its SBIR program, is seeking innovative research and development for a low-cost Acoustic Rainbow Emitter (ARE) to reduce the acoustic signature of unmanned aerial systems and improve survivability for ARSOF operations. The work focuses on a Phase I feasibility study to evaluate viable system designs that can redirect sound away from the ground, push emissions toward the atmosphere, and meet the stated size, weight, visual signature, and adaptability targets. The topic emphasizes at least a 50% acoustic reduction, low-noise output toward the ground, and compliance with ITAR and EAR controls, with Phase II intended to develop, install, and demonstrate the most feasible prototype on a UAS. The opportunity is pre-release, with the solicitation opening on April 15, 2026 and closing on May 13, 2026 at 4:00 PM UTC.
