What is the role of a fast attack submarine (SSN)?

A fast attack submarine (SSN) is primarily designed for anti-submarine warfare, which involves hunting and destroying enemy submarines. These submarines are equipped with advanced sonar systems and torpedoes that allow them to detect, track, and engage enemy submersible threats effectively. In addition to their primary role, fast attack submarines can also perform various other missions such as intelligence gathering and supporting special operations, but their core purpose is to combat other submarines and protect carrier strike groups from underwater threats.

While fast attack submarines have capabilities that can come into play in ballistic missile attacks or surface naval battles, these missions are not their main focus. Fast attack submarines excel in stealth, speed, and maneuverability, making them ideal for underwater combat scenarios against other submarines rather than engaging surface vessels directly or launching missile attacks from the sea.
