HS 3 ships

Apart from the Assault Scout, are there any other examples of HS3 ships? Also, would it possible for an HS 3 ship to carry a shuttle externally? I ask as I am currently mulling over ideas for an adventure. My RPG group is planning on playing Star Frontiers for the first time since the late 1980s, and I was wondering whether some sort of HS 3 ship design might be out there. At some point they may be able to use such a ship, being a small group, and possibly by using a slightly militarised civilian example.
