Resonant Sciences is a research and development firm headquartered in Dayton, Ohio. We operate at the cutting edge of aerospace and defense, designing, building, and deploying advanced technologies that strengthen survivability and deliver mission advantage. Our work spans government and commercial sectors, where speed, precision, and innovation aren’t optional—they’re required. We operate at the intersection of three core domains—Advanced Apertures, Mission Systems, and Signature Systems & Diagnostics—and it’s in that overlap where the real breakthroughs happen. Our vertically integrated model and high-velocity culture let us design, build, test, and deploy faster than the fight evolves, turning bold ideas into fielded capabilities that give our customers the decisive edge. From dielectric to FSS, across air, sea, and ground, our Advanced Apertures team engineers radomes and antenna systems for more than survivability—they engineer performance. Every solution is built to withstand extremes, preserve low signatures, and enable mission-critical connectivity. With unmatched integration expertise, they design, deliver, and test hardware that doesn’t just work—it wins. Our Mission Systems team thrives in denied and degraded environments, delivering capabilities in concealed communications, interference mitigation, GPS De-Jam, Alt-PNT, and electronic warfare. From custom boards to ASICs, they bring advanced concepts to life with speed, precision, and combat-ready execution. The Signature Systems & Diagnostics team closes the loop, designing and building in-house solutions that span analysis, sponsor-led R&D, qualification testing, and production workflows. Whether in a cutting-edge lab or a high-stakes production floor, our systems deliver the precision, repeatability, and speed needed to validate what’s next. From concept to combat, Resonant Sciences delivers operational advantage—right now.
