The Navy Radio and Sound Laboratory was originally built in San Diego during World War II to study radiowave and underwater acoustic propagation effects. The laboratory has grown over the years and has undergone many organizational and name changes since then to become what is currently the Space and Naval Warfare Systems Center San Diego SSC San Diego. What is now the Atmospheric Propagation branch at SSC San Diego has been in the business of researching and modeling effects due to atmospheric conditions on radiowaves since the 1940s. Primarily funded by the U.S. Navy, much of the work we do in the Atmospheric Propagation branch has been not only in the propagation research area but also in the development of applications displays and assessment tools specifically for use by the U.S. Navy. However, a software package with the fanciest GUI wrapped around the most scientifically accurate propagation model in the world will not be used by many if the model executes slowly. Therefore, we spend a great deal of effort in designing an efficient model, automating much of the input parameters needed to get meaningful results from the model. This paper will focus primarily on the Advanced Propagation Model APM, developed by the Atmospheric Propagation branch at SSC San Diego, and looks at initial developments of the model along with approximations made in its design for consideration of the operational user.
