1 appearances
Purpose
To temporarily divide internal spaces and delay structural compromise during an emergency evacuation.
Significance
The Ark's bulkheads represent the premature failure of human defenses against the Wirrn, turning a standard naval design into a critical vulnerability. Their inadequacy underscores the facility's hasty construction and the dire consequences of underestimating the alien threat. The Doctor's urgency stems directly from their inability to withstand the swarm's advance.
