Which statement best describes the difference between early warning radar and fire control radar?

• A. Early warning radar detects targets at long range while providing initial track data.
• B. Fire control radar is used to provide long-range target detection.
• C. Early warning radar and fire control radar perform weather mapping.
• D. Early warning radar detects targets at long range and provides initial track data; Fire control radar locks onto a target for engagement and guiding the interceptor.

Answer: (D)

The difference hinges on the roles of two radar types in air defense: detection versus engagement guidance. Early warning radar scans wide airspace, detects targets at long range, and provides an initial track to cue other sensors and weapons. Fire control radar, once a target is chosen for engagement, locks onto that target and supplies precise tracking data to guide the interceptor or missile, including lead and pointing information for a hit. The statement that combines both functions—long-range detection with initial track data, plus locking onto and guiding the interceptor for engagement—accurately captures their distinct roles. Other options either misattribute long-range detection to the fire control radar, suggest weather mapping, or omit the engagement-guidance function altogether.
