Which UAV uses a pneumatic launcher and recovery system?

• A. MQ-4C Triton
• B. RQ-2A Pioneer
• C. RQ-21 Blackjack
• D. X-47B

Answer: (C)

The RQ-21 Blackjack is known for its use of a pneumatic launcher and recovery system. This type of system utilizes compressed air to propel the UAV into the air, making it suitable for short takeoff and landing operations without the need for a traditional runway. This capability is particularly valuable for maritime operations, where space might be limited on naval vessels.

In the context of unmanned aerial vehicles (UAVs), pneumatic launchers provide rapid deployment options and can operate in varied environments, enhancing the flexibility of the platform. The use of a recovery system, often involving a net or similar device, ensures the UAV can be safely recovered without extensive infrastructure, allowing for operations in remote and diverse settings.

While other UAVs, like the MQ-4C Triton or X-47B, have different launch and recovery systems (such as catapults or carrier landings), the specific design and use of the pneumatic launcher and recovery system are characteristic features of the RQ-21 Blackjack, ultimately making it the correct choice in this context.
