The analysis of the performance of a rocket-boosted missile during the boost-phase portion of its flight generally requires that one solve a set of simultaneous differential equations with variable coefficients for a large variety of initial conditions. Analytical methods of solution are formidable if not impossible and consequently ways and means have been developed to accomplish the task with minimum possible effort while maintaining sufficient accuracy and reliability. This paper consists of a collection of four approaches to the problem and is presented with the hope that future analysts will not have to tread the same ground again. The particular treatment outlined here is for a cruciform missile-booster combination, completely symmetrical with respect to any two normal planes passing through the longitudinal centerline. The extension of the methods to unsymmetrical configurations is simple since it merely adds one more equation. The additional volume of calculations is another matter. Since the paper is concerned only with the boost phase performance, the word missile is used in the text to mean the missile-booster combination.
