What recovery method is used for the RQ-11 Raven?

The RQ-11 Raven utilizes a hand launch recovery method, which is specifically designed for ease of use by operators in the field. This type of launch allows for quick deployment in various environments, making it suitable for missions that require rapid reconnaissance capabilities. The hand launch method emphasizes portability and simplicity, as the operator simply tosses the Raven into the air, where it automatically transitions to flight mode.

This method is advantageous in situations where a catapult or more complex launching apparatus may not be available or practical. Additionally, the hand launch helps in reducing the logistical footprint and simplifies the setup process, which is critical for operations where mobility and rapid installation are essential.

In contrast, the other options do not apply to the Raven's operational design. A catapult launch typically requires more infrastructure and is not suited for the Raven's design. Wheeled recovery is not applicable since the Raven does not land on wheels but rather descends to a controlled landing via a parachute. An air retrieval system is also not utilized by the Raven, as it is specifically designed for hand launching and recovery. Thus, hand launch is the most effective and appropriate recovery method for the RQ-11 Raven.
