Which sequence best describes the 'kill chain' concept in maritime air defense?

• A. Sensor-to-shooter sequence that integrates detection, tracking, classification, cueing, and engagement across layers to maximize interception opportunities.
• B. A simple incident-response flow with a single sensor.
• C. A logistical supply chain for ammunition.
• D. A maintenance routine for shipboard weapons.

Answer: (B)

The kill chain in maritime air defense is the end-to-end sequence from detection to engagement, designed to bring a threat down by coordinating sensors, decision-making, and weapons across multiple defense layers. It starts with detection from radar and other sensors, then moves to tracking and identification to determine threat priority, followed by cueing a shooter with a targeting solution. Decisions to engage are made with ROE and risk assessment in mind, and the engagement is carried out by the appropriate weapons system across the layered air defenses, with data fused from multiple sources to maximize intercept opportunities.

This description is superior because it captures the full, integrated process rather than a single-step or isolated task. Treating the kill chain as a simple incident-response flow with one sensor misses the multi-sensor fusion, cross-layer coordination, and rapid decision-making required to counter modern sixes and saturation attacks. Describing it as a logistical supply chain or a maintenance routine misses the operational sequence that connects sensing, targeting, and shooting in real time, which is essential for effective maritime air defense.
