Remote Multi-Mission Vehicle - (RMMV)

The Remote Multi-Mission Vehicle (RMMV) is a major component of the Remote Minehunting System (RMS). The RMS integrates the RMMV and the variable depth sensor (VDS), the AN/AQS-20A. The RMMV is an unmanned, autonomous, semi-submersible, high endurance, low-visibility system that will be operated and maintained from the Littoral Combat Ship (LCS). The RMMV is capable of both line-of-sight and over-the-horizon operations. The off-board vehicle has self-contained control, propulsion, power, and navigation features. As many as two RMMVs may be operated from the LCS simultaneously. It is capable of real-time communications of mine reconnaissance sensor data as well as automatic search and recording modes. The RMMV tows the AN/AQS-20A minehunting sonar system for detection, classification, and localization of mine-like contacts and identification of bottom mines. The host ship will be equipped to conduct data processing, display, and recording, and will communicate tactical mine reconnaissance data to other Naval forces. Fueled for long endurance, the RMMV’s diesel marine engine and high-efficiency propulsor will propel the vehicle. The RMMV’s coverage search rate can find mines in deep and shallow water with high probability. The RMMV can be pre-programmed to perform autonomously or be manually controlled via a data link.
Naval mines pose a significant threat to U.S. and allied shipping, particularly in navigation choke points and transit lanes. The RMS is the workhorse of the LCS Mine Countermeasures Mission Package. The RMMV, as part of the RMS, will satisfy the U.S. Navy’s need for an organic (off-board) surface ship mine reconnaissance capability, designed to conduct rapid reconnaissance of bottom and moored mines from the deep-water region to the very shallow water region, and determine the presence of mines and safe routes or operating areas around potential minefields.

During September and October 2014 two RMMVs embarked USS Independence (LCS 2) in support of a MCM Mission Package Developmental Test (DT) that demonstrated end-to-end performance of the MCM Mission Package. The RMMV program is scheduled to conduct a DT in Q1FY15 off the coast of West Palm Beach, Fla. This DT will validate the configuration that will support the MCM Mission Package TECHEVAL and IOT&E in FY15.
