How USS Nautilus changed the anti-submarine problem

How much did USS Nautilus change anti-submarine warfare?

The answer sees a major capability change within a problem navies were already anticipating, with national and allied exercises used to test their responses.

Nautilus's sustained underwater speed and endurance are placed alongside an ASW problem navies were already anticipating. Fast, deep-diving Soviet conventional submarines developed from German information had encouraged work on methods to counter more capable boats. Once nuclear submarines became available, navies could test tactics against their own boats or through exercises with an ally. The discussion briefly struggles to recall the first boat's name before Nautilus is supplied later. The account emphasizes continuity in ASW preparation while acknowledging the new capability.
