Which class uses diesel-electric propulsion?

• A. Yasen class.
• B. Borei class.
• C. Akula class.
• D. Varshavyanka class.

Answer: (D)

Diesel-electric propulsion means the submarine uses a diesel engine to run a generator that charges onboard batteries, and when submerged it powers the propeller with electric motors from those batteries. This setup is quiet and cost-effective, but submerged endurance is limited by battery capacity. The Varshavyanka class is the Russian designation for the improved Kilo-class, a conventional submarine built around this diesel-electric propulsion system. It relies on diesel engines to recharge its batteries and then operates underwater on electric power, which is characteristic of non-nuclear submarines. The other classes listed are nuclear-powered, using a reactor to provide propulsion energy, giving them much longer submerged endurance and greater speed. Therefore, the class that uses diesel-electric propulsion is the Varshavyanka class.
