How many parts in a submarine?

A submarine typically consists of several key parts, including the hull, which provides structural integrity; the sail or conning tower, which houses navigation equipment; the propulsion system, usually consisting of diesel-electric or nuclear power; and various systems for life support, weapons, and sonar. Additionally, there are internal compartments for crew living quarters, control rooms, and storage. The exact number of parts can vary significantly depending on the submarine's design and purpose.
