The Navy took delivery of the third low-rate production model Remote Multi-Mission Vehicle (RMMV) on Dec. 21. Formerly known as the Remote Minehunting Vehicle (RMV), the RMMV was originally designed to detect and classify sea mines. The name was changed because RMMV missions are being expanded to include anti-submarine warfare applications and maritime reconnaissance. The RMMV is a robust unmanned, semi-submersible, semi-autonomous vehicle that can be adapted to a broad spectrum of applications and missions, including towing variable-depth sensors to detect, localize, classify and identify undersea threats at a safe distance from friendly ships.
