What was the designed lifespan of DSP satellites?

• A. 10 years
• B. 5 years
• C. 15 years
• D. 20 years

Answer: (B)

The designed lifespan of Defense Support Program (DSP) satellites is five years. This timeframe reflects the engineering and operational considerations taken into account during the satellite's development. DSP satellites were intended to provide early warning of missile launches, and while they were designed for a lifespan of five years, many of them exceeded this timeframe in actual operation, continuing to function well into their extended years through robust engineering and careful management of resources. Thus, while the initial expectation was set at five years, the effectiveness and longevity of these satellites often surpassed that baseline, contributing significantly to national security and operational capabilities.
