Ranger vehicle provides the same complete autonomous capabilities as AN/BLQ-11. The L&R system releases the vehicle from a protective cage 100-150 ft underneath the air-water interface in up to SS4, and can recover the vehicle in the same way in up to SS5. The Echo Ranger vehicle is 50-in. high, 50-in. wide and 18 ft. long. It weighs 11,700 lb dry (including 977 lb. dry payload), and has a 10,000 ft. (3,000 m) working depth with speeds up to eight knots. While on deck, the topside C2 equipment downloads the mission plan to the vehicle over a detachable Ethernet cable. At the same time, the vehicle batteries are recharged for the next sortie. While deployed in the water, the vehicle and topside C2 communicate via a pair of COTS acoustic modems. A low speed acoustic modem is used for vehicle C2 (as needed), while a high speed acoustic modem is used for real-time payload data uplink. The deployed vehicle normally operates without topside intervention, and employs a high precision inertial navigation system with optional external LBL resets from pre-deployed bottom-moored Deep
UUV docked with SSN
Ocean Transponders (DOTS). For use as a UDNS mobile node, Echo Ranger meets all the key requirements as indicated in Table 0-2.
Scan Eagle
The Scan Eagle is a 40 lb. (18 kg) Unmanned Aerial Vehicle (UAV) designed for continuous mission of 15+ hours, cruising at speed of 50 knots at an altitude of 5,000m. The system was designed for autonomous field operation. Scan Eagle is 7-in. diameter by 48-in. long with a one ft wingspan. It weighs 39.6 lb. with fuel, and carries a payload of 6 kg with an operating ceiling of 5,000 m for over 16 hours (gas) or 28 hours (JP-5). Maximum level speed is 70 knots. It can be launched and retrieved over any terrain, including naval operations. Scan Eagle C2 is provided by a Harris SECNET11 radio (802.11b + Type I encryption), with 5 nm range @ 500 ft. The UAV is equipped with nose-mounted inertial-stabilized camera turret, designed to track an object of interest for extended periods of time. The gimbal carries either
