Which airspace is defined as a joint engagement zone where multiple air defense systems engage air threats?

• A. JEZ Joint Engagement Zone
• B. HIDACZ High-density airspace control zone
• C. LOMEZ Low altitude missile engagement zone
• D. SAAFR Standard-use Army Aircraft Flight Route

Answer: (A)

A joint engagement zone is airspace designated for coordinated engagement by multiple air defense systems against air threats. In this zone, sensors and shooters from different platforms work together under a unified fire-control solution, allowing a threat to be engaged by more than one system as needed. This coordination helps maximize engagement effectiveness and reduces the chance of a threat slipping through gaps by leveraging the strengths of diverse weapons and radars.

Other zones serve different purposes: a high-density airspace control zone is about managing and controlling traffic in congested airspace, not specifically coordinating joint engagements; a low altitude missile engagement zone targets engagements at low altitudes under specific rules of engagement; and a standard-use Army Aircraft Flight Route is simply a designated path for aviation operations, not an engagement zone.
