Which submarine feature is associated with the USS Jimmy Carter (SSN-23)?

• A. 100-foot hull extension
• B. Nuclear propulsion
• C. Ballistic missile capability
• D. Most advanced sonar

Answer: (A)

The submarine is known for a distinctive physical modification: a 100-foot hull extension. This extra length was added during a refit to create substantial internal space, enabling the ship to carry mission-specific equipment and serve as a testbed for advanced systems and special operations support. That extended hull is what uniquely identifies the USS Jimmy Carter among submarine designs. Nuclear propulsion is standard for this class, ballistic missile capability belongs to a different type of submarine, and while it might carry advanced sensors, the hull extension is the standout, defining what this vessel is most closely associated with.
