Which aircraft has a maximum speed of 140-145 knots?

The AH-64A Apache has a maximum speed of approximately 140-145 knots, making it one of the fastest helicopters in the U.S. Army's inventory for attack missions. This speed is significant because it allows the Apache to perform its primary functions effectively, such as reconnaissance, close air support, and engaging ground targets. The aircraft's speed, combined with its agility and advanced avionics, enhances its operational capabilities on the battlefield, allowing it to maneuver quickly and respond to changing tactical situations.

In contrast, the other aircraft listed have different performance specifications. The CH-47 Chinook, for example, is primarily designed for cargo transportation and has a lower maximum speed suited to that role. The UH-1 Huey, while historically significant and also versatile, typically operates at lower speeds compared to the Apache. Lastly, the AH-1 Cobra, while an attack helicopter like the Apache, generally has a different speed profile and is not typically classified with the same maximum speed. Understanding these distinctions is crucial for recognizing the varying roles and capabilities of these helicopters within military operations.
