What is the maximum nominal range for Strategic Air Defense?

• A. 50
• B. 75
• C. 100
• D. 125

Answer: (C)

Maximum nominal range is the farthest distance at which Strategic Air Defense can be expected to detect, track, and engage threats under standard conditions. It reflects the combined limits of sensors, fire control, and interceptor reach, along with the time needed for identification and command actions. Among the options, the correct one is the value that represents the upper bound of that defensive envelope—the highest of the presented options. Choosing a smaller value would leave gaps in coverage, while choosing a value beyond the defined envelope would exceed the established limits. So this upper-end value is the best choice.
