Silencing with Acoustic Rainbow Emitters (SWARE)
SBIR Opportunity Analysis
U.S. Special Operations Command (SOCOM) is seeking SBIR research to develop a low-cost Acoustic Rainbow Emitter for unmanned aerial systems to reduce and redirect UAS acoustic signatures for ARSOF stealth operations. The work calls for a feasibility study in Phase I and, in Phase II, development, installation, and demonstration of a prototype system suitable for use from a UAS during terminal attack or when directed by the operator. The concept must target at least a 50% acoustic signature reduction, redirect sound away from the ground, keep emissions inaudible to humans, remain easy to apply, stay under 1 kg for a Group 1 UAS or 3 kg for a Group 2 UAS, maintain a low visual signature, and adapt across multiple UAS platforms; the topic is also identified as subject to ITAR and EAR regulations. The topic is SOCOM254-008, with applications opening April 13, 2026 and due May 13, 2026 at 4:00 p.m. UTC.
