How quickly can the AN/MPQ-64A3 be emplaned?

The AN/MPQ-64A3, also known as the Sentinel radar system, is designed for rapid deployment and emplaning. The correct answer is that it can be emplaned in 25 minutes or less. This quick emplaning capability is crucial for air defense operations, as it allows military units to respond swiftly to threats and reposition as necessary in dynamic combat scenarios.

The system is engineered to facilitate timely operations, enabling it to be set up and operational in a minimal amount of time. This ability enhances the overall effectiveness of the air defense command and control structure, allowing for persistent surveillance of airspace and timely engagement of aerial threats.

In contrast, the other options reflect longer timeframes for emplaning, which would not align with the operational requirements of rapid response inherent to the design and purpose of the AN/MPQ-64A3 system. Ensuring that such sophisticated equipment can be transported and set up quickly is a fundamental aspect of maintaining air superiority in a rapidly changing battlefield environment.
