I have notice a problem with some of the AI shuttle, early in the game. They do not have life support, cockpit or engines. The interesting thing was the federation's first shuttle had only weapons, later on in the game the shuttles were fully equiped with life support, cockpit, engines and weapons. What I think happen was that the AI researched regular shuttle technology first and later research they own race's ship technology, that includes shuttle technology too.
