Mistral USV Convoy

Mistral USV Description

• The Mistral USV is an advanced unmanned platform featuring the Stiletto M-hull Technology, user-friendly control interface and composite material

• The Mistral USV’s double M-hull shape provides unprecedented efficiency, stability, & payload for a variety of missions. The monocoque, composite construction allows flexibility to carry modular sensor packages, supplies and/or equipment on standard 463L pallets or ISU60 containers.

• The Mistral USVs Command & Control (C2) system uses a smart, self-tuning autopilot designed to simplify operations with autonomous features for coordinated operations, fail-safe scenarios and pre-programmed objectives.

• The Mistral USV is propelled by two, widely spaced waterjets driven by conventional twin diesel engines with a range of over 500 nautical miles.

Select Platform Features

•  Reinforced keels for well deck landing on mothership. •  Cargo bay doors on transom and deck with optional transom ramp. •  Modular cargo bay configuration based on ISU 60 & 463L pallet system. •  Large payload capability with shallow draft. •  Smooth & efficient ride quality in high sea state •  Wide stable platform in both trim and heel •  Operated manned or unmanned •  Capable of handling large towed arrays. •  Single point lifting and deck storage without cradle •  Widely separated, twin waterjet propulsor layout for precise control. •  Optional fuel transfer system to adjust trim with variable loading conditions.

Major Equipment List

•  Caterpillar C9 Diesel Engines (2) •  Hamilton WaterJets with ZF280 Gearbox •  Engine Instrument and Control Package •  Hydraulic Steering System •  Diesel Fuel Tankage and Monitoring System •  Bilge, Safety and Fire Suppression Systems •  AC/DC Electrical System with Genset Supporting Equipment •  Electronics and Navigation System. •  Turn Key, Self-Tuning Autonomous Control Package •  Manual Control Helm Station (2 seats)

General & Mechanical Arrangements

Select Unmanned Features •  Semi-autonomous - automatically following a preplanned mission with human intervention

as required. •  Manual - full remote operation (fully manual i.e. docking) •  Pre programmed Loss of Comms plan in the event of Link loss, Vessel returns to safe

location either route retrace or direct vector •  In either of the autonomous modes, updates to the mission may be made at any time. •  The command and control system operates on dual fully encrypted frequencies offering

redundancy and security or non-encrypted UHF RF link for line-of-site operations •  There is the option of using multiple Ground Control Stations to increase the range of USV

operations. The on board Command and Control Module communicates in full duplex mode over both frequencies, significantly increasing data throughput and bandwidth in transmitting and receiving data.

•  The USV maintains full preprogrammed control routines in the event of a failure in one or both of the radio links.

•  Convoy auto follow – multiple USV’s navigate same track in formation autonomously •  Contact/collision avoidance options

Control System Capability

Operational Scenario 1:"Mothership Control with C2 Relay Nodes

•  Mothership operates over the horizon at a convenient, safe location. •  USV Mistrals operate as command & control (C2) nodes for forward Mistrals

to backup or replace UAVs and/or satellite comms. •  Forward USV Mistrals operate as a group or individually.

Operational Scenario 2:"Mistral Control with Force Multiplying Squadron

•  One manned Mistral controls a squadron of unmanned Mistrals. •  USVs can be controlled individually or relative to one another. •  Navigation by manual Joy-stick Control from the manned Mistral or

autonomously by Waypoint, Vector (speed/heading) or Relative Tracking.

Operational Scenario 3:"Waypoint Control with Convoy Auto-Follow Mode

•  One manned Mistral controls a squadron of unmanned Mistrals. •  USVs can be controlled individually or relative to one another. •  Navigation by manual Joy-stick Control from the manned Mistral or

autonomously by Waypoint, Vector (speed/heading) or Relative Tracking. •  Ideal for delivery or retrieval of cargo, equipment or personnel.
