A Three-Body, Three-Dimensional Intercept Simulation Program
TACTICS is a computer program written in FORTRAN IV which mathematically simulates the dynamics of flight in three-dimensional space of as many as three vehicles simultaneously. The purpose of the Memorandum is to acquaint users with the capabilities and basic theory of the program and to serve as a reference manual for those who wish to use the program. The first part of the Memorandum describes the theory of operation and is oriented toward those with a mathematical or technical background. The second part is concerned with how to use the program, i.e., how to provide input data, select options, and develop a flight program. A number of illustrative examples of a wide variety of problems are given in detail, including data and FORTRAN listings. In many cases it should be possible to set up a specialized problem by modifying or combining various features of the examples.
