What describes the Akula class submarine?

• A. A diesel-electric attack submarine with a single hull.
• B. A ballistic missile submarine.
• C. A nuclear-powered fast-attack submarine with a shield hull.
• D. A nuclear-powered attack submarine with a double hull.

Answer: (D)

Submarine classes are defined by propulsion and hull design. Akula class submarines are nuclear-powered, built for fast-attack roles, and use a double-hull design. The nuclear reactor gives the vessel long underwater endurance and high speed, which suits anti-ship and anti-submarine warfare rather than strategic deterrence. The double hull—an inner pressure hull plus an outer light hull—provides structural strength and buoyancy characteristics typical of this design. This combination distinguishes it from diesel-electric subs, which rely on batteries and are not nuclear-powered, and from ballistic-missile subs, which are built primarily for carrying strategic missiles. The idea of a shield hull isn’t the standard description for this class; the known configuration is double-hulled. So the best fit is a nuclear-powered attack submarine with a double hull.
