Maximum reinforced bulkheads improve the ship's ability to contain fire and flooding. That internal subdivision adds hull weight, which must be recovered elsewhere in the design. The extra weight reduces the margin available for fuel and other capabilities. Damage control therefore belongs inside the ship's overall weight balance.

Maximum reinforced bulkheads help contain flooding and fire, but their weight reduces the margin available for fuel and other design choices.
