The Coril shuttle is a venerable design, originally built by the Tarbotians in the 2070s, but copied by many nations and built since including by the DDS/NS/UNDF. Although it continues to be a highly useful ship, DF are now looking into a replacement which could enter service in the early 2130s.
At the moment the project is known as the Next Generation Utility Shuttle (NGUS) though DF projects tend to change name as they progress. NGUS will be of a similar size to the Coril, DF are said to be looking at a common core for the ship with a range of different crew compartments for different roles. DF have approached Consolidated Spacecraft and other commercial spaceship builders to assist.
