Anechoic coating: A type of sonar-absorbing material applied to submarines to reduce their acoustic signature. It consists of rubber or other materials with properties that minimize sound reflection.

Anti-ship missiles are guided missiles designed to engage and destroy naval vessels. They are typically used by aircraft, ships, or submarines to attack enemy ships.

Cruise missiles are self-propelled, guided weapons launched from platforms like attack submarines (SSNs) to deliver warheads over long distances with precision.

Electronic Support Measures/ELectronic INTelligence suite: a sensor system on submarines that detects, identifies, and locates radar and communication emissions for passive threat assessment and tactical advantage.

Sonar system mounted on submarine's flanks to detect targets.

Relating to or using nuclear energy, typically fission, for propulsion or power generation in military vessels.

A pump-jet propulsor is a type of propulsion system used in submarines, utilizing a pump-jet to generate thrust.

A system of hydrophones towed behind a vessel to detect submarines and torpedoes, minimizing interference from the ship's self-noise.
