These volumes have been prepared to provide information on the US Army Research, Development, Test and Evaluation Program for Congressional Committees during the Fiscal Year 1982 hearings. These volumes contain a descriptive summary for each program element to be financed furing FY 1982. Descriptive Summaries for projects within the program elements to be financed during FY 1982 for $5.0 million or more appear immediately following the applicable program element. Where there are several items under development within a project, a separate summary has been provided for each item that exceeds $5.0 million during FY 1982. A Test and Evaluation Section is provided for all major weapon systems. The formats and contents of these volumes are in accordance with guidelines and requirements of the Congressional Committees insofar as possible. Information previously provided in the SAC Data Book is consolidated into these volumes. The SAC Data Book information appears at the beginning of each program element descriptive summary. A direct comparison of FY 1980, FY 1981, FY 1982, and FY 1983 data in this Program Element Listing with data shown in the Program Element Listing dated January 1980 will reveal significant differences. Many of the differences are attributable to the following factors: (a) Restructuring of the FY 1980 and FY 1981 programs for comparability to the FY 1982 program structure; (b) Reclassification to provide greater visibility and contribute to the effective management of the RDTE program. The funding information used in these volumes corresponds to that contained in the President's Budget except for FY 1980.
