Figure 2.4: (a) Long-term Mine Reconnaissance UUV (Courtesy of The Boeing Company);  As with robots in the other services, UUVs come in various sizes, from man-portable to very larg “ig. 2.4a shows Boeing's Long-term Mine Reconnaissance System (LMRS) which is dropped into tk ocean from a telescoping torpedo launcher aboard the SV Ranger to begin its underwate surveillance test mission. LMRS uses two sonar systems, an advanced computer and its own inerti vavigation system to survey the ocean floor for up to 60 hours. The LMRS shown in the figure about 21 inches in diameter; it can be launched from a torpedo tube, operate autonomously, retur ‘0 the submarine, and be guided into a torpedo-tube mounted robotic recovery arm. A large UU' he Seahorse, is shown in Fig. 2.4b; this vehicle is advertised as being capable of ‘independer yperations’, which may include the use of lethal weapons. The Seahorse is about 3 feet in diamete 28 feet long, and weighs 10,500 Ibs. The Navy plans to move toward deployment of large UUVs k 1010. These vehicles may be up to 3 to 5 feet in diameter, weighing perhaps 20,000 Ibs.  2010. These vehicles may be up to 3 to 5 feet in diameter, weighing perhaps 20,000 Ibs.
