What UAS is designed to conduct ISR operations and is capable of both ground and water landings?

The correct choice is the Puma, which is specifically designed for Intelligence, Surveillance, and Reconnaissance (ISR) operations. One of its outstanding features is its versatility in landing, as it is capable of operating on both ground and water surfaces. This adaptability makes the Puma particularly valuable for military and reconnaissance missions, where it can be deployed in a variety of environments without the need for extensive infrastructure.

The Puma UAV is lightweight and portable, which contributes to its effectiveness in field operations. Its design allows for easy transport and deployment, enabling rapid response in various situations, including maritime environments. This capability sets it apart from larger systems that may require airstrips or other specific landing facilities.

Other UAS options, such as the RQ-7B Shadow, MQ-9 Reaper, and Global Hawk, are indeed advanced platforms for ISR but do not possess the same ability to land on both ground and water. The RQ-7B Shadow and MQ-9 Reaper are primarily designed for land-based operations and do not offer this dual landing capability, while the Global Hawk is focused on high-altitude, long-endurance missions and is not structured for ground or water landings.
