The Navy could hear an Alfa-Class submarine coming, but could it outrun one?

The Project 705 Lira—better known abroad as the Alfa-class submarine by NATO—was basically a submarine race car, and looked the part with svelte tear-drop shaped hull, rakishly trimmed-down sail designed to minimize aquadynamic drag, and even its convertible-style pop-up windshield.     Military vehicles are generally designed out of a relentless quest for efficiency, but the Alfa’s iconic shape exemplifies how kinematically optimal designs often possess a striking aesthetic of their own.  This first appeared earlier and is being reposted due to reader interest.

Speed has often held a mixed appeal in submarine warfare. After all, even very quiet submarines become noisy when they're tearing through the ocean at their maximum speed of 20 to 30 knots. As typically the goal in submarine warfare is to detect an unaware adversary and launch torpedoes without being detected in return, many submarines cruise at little more than a brisk jog to minimize noise. However, speed also enables more aggressive maneuvers against alert enemies and incoming torpedoes, and the ability to close with or disengage from adversaries as the situation dictates. And sometimes sp...

Soviet nuclear-powered attack submarines tended to be faster and deeper-diving than their Western counterparts. Here's What You Need to Remember: The Alfa’s low reliability and maintainability at sea meant the submarine was conceived of as a sort of “interceptor,” kept ready at port to dash after key surface warships targets. In this role the Alfa amounted to a formidable foe to NATO submariners.
