Understanding past military technological successes is crucial to defense science and technology investment and management. This study is the second in a series that examines some of the key factors that have led to meaningful technology generation and ultimate incorporation into the U.S. Army weapons systems we see in the field today. The first report covered the development of the Abrams tank.1 Analysis of the development of the Javelin and Stinger missiles will follow. The results of all studies will be compiled in a wrap-up report that will include a look at the implications of the findings for today's science and technology environment.
