Which statement best describes the design features of the casualty power system?

• A. Maintain WT integrity; Flexibility; Interchangeability; All of the above
• B. Maintain WT integrity only
• C. Flexibility and Interchangeability
• D. None of the above

Answer: (A)

Designing a casualty power system centers on keeping critical functions powered while staying safe under damage. Maintaining watertight integrity is essential because it prevents flooding from spreading when compartments are compromised; the system is built to route power without breaching separating bulkheads or seals. Flexibility is also built in so the system can adapt to different casualty scenarios—reconfiguring feeders, using alternate power sources, and directing power to different equipment as conditions change. Interchangeability means components are standardized and can be swapped quickly in the field, reducing downtime and easing maintenance. When you put these features together, you get a comprehensive capability: the system remains operable, adapts to the damage situation, and can be repaired or reconfigured rapidly. That combination is why the description listing all three characteristics is the best.
