Neither the Fesarius nor any other vessel of the First Federation has been seen since 'The Corbomite Maneuver'.Д«ased on Star Trek: Star Charts (p. The final draft elaborated that the Fesarius' 'cell-like sections' were to be 'vari-colored' and the same script further stated, ' Not only is it formidable in size, but it is also visually impressive, looking all-powerful and frighteningly superior.' Both scripts characterized the vessel as a 'colossus' that dwarfed the Enterprise. It is in the shape of a round cluster of grapes (or fish eggs or lead shot or a honeycomb), but it looks very functional Some of its cell-like sections pulse with an inner light.' In the second revised draft of the script (dated ), this description was simplified, with the Fesarius said to be 'in the shape of a round cluster of balls.' Also, the ship wasn't referred to as seeming 'very functional', and the words 'some of' were omitted. In the final draft script of 'The Corbomite Maneuver' (dated ), the Fesarius was described thus ' No appraisal is possible, for this object is completely alien in appearance. The vessel was able to scan the entirety of the USS Enterprise in a few seconds, in sufficient detail to then override and shut down some of its systems, a level of control that was described as 'extremely sophisticated' and 'brilliant.' ( TOS: ' The Corbomite Maneuver') Even at a distance of 5,000 meters, the Fesarius still filled the entirety of the Enterprise viewscreen at normal magnification. Commander Spock estimated the vessel to be 'a mile in diameter.' However, the screen shots showing both ships indicate that the Fesarius clearly is much larger than Spock's estimate, because one mile would be approximately 5.5 times as long as the 947-foot Enterprise. The mass of the Fesarius was beyond the ability of 23rd century Starfleet instruments to register. The ship was able to dispatch at least one small craft, described as a ' pilot vessel', and could be controlled by just one crewman using a very simple-looking interface. The Fesarius was very large and spherical, with the surface made up of smaller, dome-like features, arranged in a distinct pattern based on triangles. The Fesarius and the Enterprise at 5000 meters
