From Foxtrot Alpha a blast from the past.
Russian Alfa [not alpha] class submarine to be resurrected?
"Russia May Revive Its High Performance Cold War Alfa Class Sub With Modern Upgrades"
"Russia’s Alfa Class fast attack submarine was the SR-71 of the undersea world during the Cold War. The Alfas were largely constructed of titanium, used a liquid-metal cooled nuclear power plant to obtain extreme speeds, and could reach depths far deeper than their competitors. Now Russia is floating the idea of building a modernized version of the design, one that leverages 40 years in technological advancement to take combat submarine automation to a whole new level."
An image of a Soviet Alfa class submarine on the surface. From that era of the Cold War this vessel causing much trepidation and the "willies" among American naval planners at the Pentagon.
Alfa as constructed those positive attributes to include:
* Titanium hull. Allowing for amazingly deep operational depth.
* Liquid-metal cooled reactor. Allowing for amazingly high under-water speed.
EVEN THE ALFA AT TOP-SPEED FASTER THAN THE FASTEST AMERICAN TORPEDO! THE LIQUID-COOLED REACTOR ABLE TO PROVIDED MORE POWER IN A SMALLER PACKAGE AND REACH HIGHER POWER IN A QUICKER MANNER! ALL DEFINITE ADVANTAGES DURING UNDERSEA WARFARE!
NO REAL WORD IF THESE ARE TO BE REFURBISHED ALREADY EXISTING HULLS OR BRAND-SPANKING NEW VESSELS! I WOULD IMAGINE SUCH SUBMARINES NOT CHEAP AND TAKING YEARS TO CONSTRUCT!
