Missile Datcom
From Infogalactic: the planetary knowledge core
Missile DATCOM is a widely used semi-empirical datasheet component build-up method for the preliminary design and analysis of missile aerodynamics and performance. It has been in continual development for over twenty years with the latest version released in March 2011.[1] It has traditionally been supplied free of charge by the USAF to American defense contractors. The code is considered ITAR and should not be distributed outside the country.[2]
