Key Details
Official Description
This topic seeks innovative research and development efforts toward a low-cost acoustic rainbow emitter attached to a UAS. Acoustic sensors are becoming more prolific on the battlefield and reducing the signature of a UAS will increase the survivability of ARSOF UAS in a non-permissive environment. As a part of this feasibility study, the proposers shall address all viable overall system design options with respective specifications on the key system attributes. Key system attributes include:

# Summary of Q&A Changes **New Question Added:** One new Q&A (Q1) addressing Phase I evaluation methodology. Government clarifies it accepts any approach meeting requirements, with hybrid methodologies (directional distribution, perceptual detectability, frequency-domain metrics) considered acceptable if performers define and justify their framework. **No substantive answer changes:** Previous Q&As (original Q1-Q4, now renumbered Q2-Q5) remain identical. The original responses regarding space constraints, 50% reduction requirement, atmospheric redirection intent, dominant frequencies, mounting restrictions, and UAS types are unchanged.
