Russia’s Alfa-Class Submarine Was a Fast ‘Titanium Terror’ with 1 Flaw
Key Points and Summary – The Soviet Union’s Project 705 Lira, or Alfa-class, was a technologically brilliant but deeply flawed submarine.
-Thanks to its revolutionary titanium hull and a compact lead-bismuth cooled reactor, the Alfa was the fastest submarine ever built, reaching speeds over 40 knots.
-The Flaw: However, this pursuit of speed created a vessel that was incredibly noisy.
-It was easy to detect due to its lack of stealth, and it had a dangerously unreliable reactor.
-The program was a costly failure, but its legend was so potent that the U.S. and U.K. had to develop new, faster torpedoes just to be able to catch it.
