What is the role of redundancy in passive defenses for space assets?

• A. Redundancy increases signal strength during jamming.
• B. Redundancy is primarily used to increase data rate.
• C. Redundancy provides backup capabilities to maintain operation during component failure or jamming, reducing vulnerability.
• D. Redundancy only adds cost with no benefit.

Answer: (C)

Redundancy in passive defenses means building in backup components and pathways so the system can keep functioning even if parts are damaged or blocked by interference. For space assets, repair or replacement isn’t quick, so having spare processors, duplicate communication links, extra antennas, and alternative power or data routes allows the mission to continue when a element fails or is jammed. This approach focuses on continuity and resilience rather than increasing signal strength or data rate. By removing single points of failure, redundancy lowers vulnerability and improves survivability in a contested space environment, even though it adds mass and cost.
