A Los Angeles-Class Sub Tied to the Pier Was Louder Than a Seawolf at 20 Knots. 70 Times Quieter, It Dove Past 2,000 Feet to Hunt Typhoons Under Arctic Ice

Automatically curated summary from 19FortyFive.

According to an article by Sean Spoonts published in 19FortyFive, the U.S. Navy developed the Seawolf-class submarine in the 1980s specifically to counter Soviet Typhoon-class ballistic missile submarines under Arctic ice. Designed for extreme stealth, the Seawolf featured a pump-jet propulsion system, HY-100 steel hull, and an operational depth exceeding 2,000 feet. It was reportedly up to 70 times quieter than the preceding Los Angeles class. However, post-Cold War budget cuts capped production at three hulls, including the specialized USS Jimmy Carter.

Context and limitations

Acoustic performance claims (e.g., being 70 times quieter than the Los Angeles class) and specific covert capabilities (such as USS Jimmy Carter tapping undersea fiber-optic cables) reflect estimates, unverified beliefs, or informal assertions rather than official confirmed Navy technical specifications.
