The Advanced Starship Design Bureau was a branch of the Federation that, in conjunction with Starfleet, oversaw the creation of new starships. The ASDB administered several shipyards throughout the Federation, including Utopia Planitia Fleet Yards. The Bureau was frequently credited on starship dedication plaques.
Numerous technical fan websites have taken the name "Advanced Starship Design Bureau." See Advanced Starship Design Bureau (websites) for more information. One such website existed at http://techspecs.acalltoduty.com and was run by a group of fans including Bernd Schenider whom also created the Ex Astris Scientia website.
