What are the four effect categories SEW aims to achieve against space-based systems?

• A. Denial, degradation, disruption, or deception
• B. Acceleration, cooling, shielding, optimization
• C. Encryption, routing, handover, synchronization
• D. Taxation, regulation, licensing, procurement

Answer: (A)

In space electromagnetic warfare, the aim is to affect space-based systems through four outcome types: denial, degradation, disruption, or deception. Denial blocks or prevents use of the asset, such as jamming a downlink to stop data from getting through. Degradation reduces performance while the system remains active, like increasing error rates or lowering sensor quality. Disruption interrupts an ongoing operation for a period, causing a temporary loss of capability or command flow. Deception feeds the system false information, such as spoofing a navigation or sensor signal to trigger incorrect actions.

The other groupings don’t fit this framework: acceleration, cooling, shielding, and optimization relate to physical or thermal design rather than adversarial effects on space systems; encryption, routing, handover, and synchronization describe networking or security processes rather than EW outcomes; taxation, regulation, licensing, and procurement concern policy and governance rather than technical effects.
