SRS has developed and is manufacturing the FUSION ve- hicle, a next-generation underwater system. The FUSION hybrid ROV is an approach to underwater vehicles that ex- empli? es design, capability, and intuitiveness. SRS under- stands operators are always looking for force multipliers, and FUSION meets this requirement with advanced sensor integration. Built mission-ready, FUSION is designed for rapid deployment during challenging missions and is trusted by navies around the world. Key technical points include: • Highly capable portable hybrid ROV • Deployable as an ROV with a tether or as an AUV

Silicon Sensing • Fully integrated imaging and navigation sensors www.siliconsensing.com • Side scan sonar, imaging sonar, HD video, DVL, AHRS,
