The Trauerschwan (トラオアシュヴァーン, Toraoashuvān?) is a prototype railgun developed by the Federal Republic of Giad's Advanced Technology Research Bureau as a hypothetical counterpart to the Morpho. It has many operational issues, such as exposed wiring, an unfinished FCS and cooling system, as well as requiring 200 seconds to reload. Despite its shortcomings, it is still considered one of the trump cards of humanity. When firing, a Reginleif is required to provide fire control.
