The report describes a computer program for calculating static forces and moments on canard-body-tail configurations. The program is applicable in the Mach number range, 0 or M sub infinity or 3, and angle of attack range, 0 or alpha 20 degrees. The theoretical development of the methods used in the program is given in Part I of the report however, for reference purposes, the various theories used are listed herein. A detailed description of the program usage, including input and output quantities, is also given. Several example cases are considered and the calculated aerodynamics compared with experimental data. In general, accuracies of plus or minus 10 can be expected for normal force and drag and the center of pressure is expected to be accurate to within plus or minus 8 of the body length.
