Perhaps uniquely among the military department, the Department of Navy may eventually acquire every major kind of unnamed vehicle (UV) Navy and Marine Corps programs for UVs to raise several potential issues for Congress. Recent U.S. military operations in Afghanistan, Chapman (2001) stressed, have highlighted the potential of unnamed vehicles (UVs) to alter U.S. military operations and improve the capabilities of U.S. military forces. Compared to equivalent manned systems, UVs are viewed as offering advantaged in a number of areas, including the following: lower procurement and operating cost. reduced risk to U.S. personnel. low observability. and the ability to operate in placed inaccessibly to people or manned platforms. Chapan (2001) describes the major roles envisaged for military UVs include various forms of intelligence, surveillance, and reconnaissance (ISR). communications relay. detection and neutralization of mines and other hazards. targeting. and strike (i.e., attack) operations. UVs may multiply the effectiveness of the manned ships and aircraft that deploy them by extending their “eyes and ears” and by permitting them to perform multiple missions in varied locations simultaneously. As the U.S. military evolves toward more distributed and networked arrangements of forces, UVs are expected to be served as “nodes” (i.e., constituent elements) in the network (Chapman 2001). O’Rourke (2002, p. 6) told that there might be distinctively among the military departments, the Department of Navy (DoN), which includes the Navy and Marine Corps, may eventually acquire major kind of UV, including unmanned air vehicles (UAVs), unmanned air combat vehicles (UCAVs), unmanned surface vehicles (USVs), unmanned underwater vehicles (UUVs ), and unmanned ground vehicles (UGVs). Various Navy and Marine Corps officers are involved in developing and acquiring naval UVs. much of the more basic development work is being conducted through the Office of Naval Research (ONR).
