Aerospace, Defense & Outsourcing Corporations
last updated 10-Aug-2021

In this directory/list you find companies at the intersection of hardware and software development –some firms are closer to either side of this spectrum while some other, as systems integrators, are right in the middle. This directory focuses on bespoke, distinctive and niche businesses. While it can be argued that to some extent many of the large firms listed in our Aerospace, Defense & Outsourcing Corporations section cover this area, we want to emphasize here not the overly generic but the cutting-edge of the generically specific.
