The Office of Naval Research (ONR) contracted with the Naval Studies Board (NSB) of the National Research Council (NRC) to establish a committee to review ONR's Air and Surface Weapons Technology (ASWT) program. The committee convened on May 14 and 15, 2002, and reviewed more than 20 science and technology (S&T) efforts that were presented as constituting the ASWT program. The committee then met separately on May 16, 2002, to formulate its findings and recommendations. This report represents the consensus views of the committee and is based on the information presented prior to and at the review, as well as on the committee members' accumulated experience and expertise in military operations, systems, and technologies.
