What UAS is designed to conduct ISR operations with ground and water landing capability?

The correct choice is the Puma, which is specifically designed for intelligence, surveillance, and reconnaissance (ISR) operations while also having the capability to land on both ground and water. This versatility allows the Puma to be utilized in various environments and scenarios, making it a valuable asset in military and civilian operations. It is equipped with sensors and payloads suited for ISR tasks, enabling operators to gather critical information effectively.

In contrast, the other unmanned aerial systems (UAS) listed, such as the MQ-1 Predator, Raven, and ScanEagle, do not possess the same capability for both land and water operations. The MQ-1 Predator is primarily focused on longer-range ISR and combat operations but does not have landing capabilities on water. The Raven is a small, portable UAS primarily used for short-range ISR missions, but it is also limited to terrestrial landings. Similarly, the ScanEagle is designed for ISR and can operate in maritime environments but typically does not have the capability to land on water as a standard function. The Puma's unique features make it stand out for roles requiring dual-landing capabilities, enhancing its operational flexibility.
