Meet the Riptide UUV-12

BAE Systems unveiled the newest addition to its unmanned undersea vehicle (UUV) portfolio, the Riptide UUV-12. The 12-in. diameter vehicle is the company’s entry into the medium UUV market – joining three small

UUV variants – and marks the ? rst new vehicle since last year’s acquisi- tion of Riptide Autonomous Solutions. “The Riptide UUV-12 system signi? cantly extends the Riptide family of UUVs by taking us into the medium UUV market,” said Jeff Smith, chief scientist at BAE Systems’

FAST Labs research and development organization. “With this medium- size platform, we are strategically aligning our modular, open architecture- based UUV platform to meet rapidly expanding applications and require- ments.”
