Which of the following aircraft is used for surveillance and reconnaissance?

The Sentinel is designed specifically for surveillance and reconnaissance missions, making it the correct choice for this question. This aircraft excels in providing real-time intelligence and has advanced sensors that allow it to gather information over large areas. Its capabilities are particularly valuable for monitoring land and maritime activities, assessing threats, and supporting operational planning by providing commanders with situational awareness.

The Typhoon, while a multirole combat aircraft, is primarily focused on air superiority and ground attack rather than dedicated reconnaissance. The Lightning, representing the F-35 stealth fighter, also serves primarily in combat roles but includes some surveillance capabilities within its multi-role functions. Atlas, typically referring to the Airbus A400M, is a tactical airlifter designed for transport rather than surveillance. Therefore, the Sentinel stands out as the aircraft specifically purpose-built for surveillance and reconnaissance missions.
