Finding pictures for escort ships was rather difficult. They only appear near the end of the show's run, and even then, only for very brief moments. This is my interpretation of some of the escort ships. The smallest one is the Connestoga escort. My concept is this is a first generation UNSC ship designed for close escort duty. It has limited range, however, is heavily armed. It is gradually being phased out for the second generation modular ships, however, is still useful in protecting the JFK carriers from other ships.
