Star Trek: Deep Space Nine

In 2370, the Bok'Nor, an ill-fated Cardassian freighter feel victim to an explosive sabotage at the hands of Maquis member, Bill Samuels. All 78 persons aboard were killed.

During a scan of the ship's debris, components included its fusion-based impulse generator, which imploded when an undetected proto-matter device caused an overload, and thus a resulting fusion shock. The Bok'Nor's holds were empty when it arrived at Deep Space Nine, having off-loaded 14 metric tons of golside ore within the Regulon system.

As with most Cardassian ships, kelindide and rhodinium are major component materials — but mercassium, a unique United Federation of Planets synthetic, is not.
