Alex Betley writing in 19FORTYFIVE makes the following points:
- Early Cold War | Summary, Causes, History, Years, Timeline, & Facts | Britannicahttps://www.britannica.com/event/Cold-War Soviet nuclear submarines were less stealthy and reliable than Western submarines.
- The Soviet Lira-class (NATO ALPHA Class) had a titanium hull and unique reactor, making it the fastest, deepest-diving submarine ever.
- Titanium is as strong as steel but half the weight enabling deeper dives; however, it’s three to five times more expensive.
- The Soviet Union scrapped the titanium-clad submarine in the early nineties as they were expensive to maintain and easy to detect.
