Intelligence on an Opponent s War Preparations, Exercises and Tests Submarine-gathered intelligence helps maintain peace, focuses military planning and operations, and minimizes battle casualties. Submarines provide the nation with a crucial intelligence gathering capability that cannot be replicated by other means. Employing multiple sensors and operating covertly, submarines can monitor any event in the air, surface, or subsurface littoral domain, providing a complete picture of the event across the full spectrum of intelligence disciplines. Reliably confirming the absence of a threat or specific activity allows planners to confidently allocate resources elsewhere, while keeping an alert watch to detect any subsequent emergence of the potential threat.
Submarines respond on short notice to taskings from civilian and military leaders.
Submarines, with their stealth, are employed to closely and continuously observe an adversary s activities without the adversary s knowledge or use of discretion.
