What does ADSI stand for?

• A. Air Defense Systems Integrator
• B. Air Defense Surveillance Interface
• C. Automatic Data Systems Interface
• D. Allied Defense Signals Integration

Answer: (A)

In air defense command and control, ADSI is about bringing together diverse sensors, command nodes, and weapons into one cohesive system. The best choice is Air Defense Systems Integrator because it captures the role of linking these different components so they can share data, maintain a common picture, and coordinate engagements across the battlefield.

The other options describe narrower or different ideas: a surveillance interface would focus only on presenting detection data, not on integrating multiple systems; a generic automatic data systems interface is too broad and not specifically about tying air defense assets together; and Allied Defense Signals Integration implies a multinational or signals-operations focus that isn’t the standard term for the integrated defense system itself.
