What class is the Varshavyanka?

• A. A nuclear-powered attack submarine.
• B. A diesel-electric stealth submarine.
• C. A ballistic missile submarine.
• D. A fast attack submarine with air independent propulsion.

Answer: (B)

Varshavyanka is the Russian Project 636 class, commonly called the Kilo-class, a diesel-electric submarine. It runs diesel engines on the surface or at snorkel depth to recharge its batteries and then operates submerged on electric power, which makes it exceptionally quiet and stealthy in coastal waters. This propulsion setup distinguishes it from nuclear-powered attack submarines and from ballistic missile submarines, which are typically nuclear-powered and carry strategic missiles. Some diesel-electric boats use air-independent propulsion to extend submerged endurance, but Varshavyanka does not rely on AIP. So the best description is a diesel-electric stealth submarine.
