Future unmanned underwater craft to be the Navy’s development trend worthy of attention.

According to the China National Defense Science and Technology Information Network reported that the U.S. Navy Office of Naval Research program to promote the level of the unmanned AUVs. The Navy Unmanned Underwater Vehicles (UUS) near the operator control the aircraft, the task can be sustained for several hours. The appearance of large displacement unmanned underwater vehicle the (LDUUV) will be more automatic control ability, be able to for several months, long-range tasks. It as mothership deployment and operation of static, dynamic sensors, persistent surveillance of coastal waters, may end up weaponry. Most of the technology of the project has been verified.

Boeing Echo rangefinder is LDUUV the initial stage of Echo rangefinder was originally built in 2011, a diameter of 5.5 m (18 ft), displacement of five tons and can dive to 10,000 feet. The Navy required to work in shallow water without assistance state. LDUUV able to detect and avoid surface and underwater obstacles and hazards. LDUUV by sonar can detect close obstacles, and acoustic sensors would be a few miles outside of the enemy ship alarm.

LDUUV second feature is the persistence. Conducted in two phases: the first two years to verify LDUUV consecutive 30-day mission of the state, after the second stage was extended to 70 days.

Echo rangefinder “provided by the battery power, about 28 hours, although the diesel engine or fuel cell can extend the time, but these techniques may be difficult for small unmanned submersible, LDUUV power plant will and weighs 3.5 tons.

LDUUV research task is to solve the long task of reliability. Boeing project leader, said that with the Boeing flight satellite expertise, developers focus on redundant systems, improve the reliability of components and self-monitoring capabilities. The submerged needs to make up for the deficiencies of the sensor and measure the severity of the other issues. The

LDUUV, there will be a large payload bay, guarantee able deployed sensors, communications buoy, a smaller UUS and weapons. The Navy is currently the focus of persistent surveillance of the over-the-horizon. However, the most significant impact may be on mine warfare.

defection mine warfare, LDUUV will be able to detect and locate mines, and then the safety of mine. LDUUV can make the offensive mine laying more controllable, secret. Mines in the transformation of the concept, LDUUV laid in large areas of mesh sensor. Sensors to track and identify a vessels monitoring within each. Based on the specific situation, you can use stationary weapons, or from the UUV deployment torpedo attack any one ship. The advantages of using LDUUV is turned on or off the mined areas, or to change the minefield size. It can make cloth minefield but not enabled. Compared with the traditional laying of mines and mine, and not too much trouble.

Navy plans to seek proposals published in 2014 LDUUV. Last October, the Naval Undersea Warfare Officer Rear Admiral Barry Bruner procurement of 10 LDUUV, a supplement to manned submarines. (China Ship Song Yang)
