Not long before the onset of the Brood War, the Bismarck was part of an Alpha Squadron force under General Edmund Duke carrying out survey missions, mapping potential colony worlds and re-establishing contact with isolated colonies. This changed with orders from Arcturus Mengsk, Duke leading Alpha Squadron to the world of Bhekar Ro to secure an alien artifact. Upon arrival, protoss and zerg forces were observed in battle against each other. With the arrival of Alpha Squadron, the battle soon became a three-way one.
Things went bad for the Bismarck from the onset, trapped in a stasis field by a protoss Arbiter. Upon the field's dissipation, the Bismarck was quickly crippled by a flight of interceptors. Before long, it had been reduced to nothing but a burning hulk in space.
