Titanium Submarines: The Powerhouse Subs Russia Built (The Navy Said No Way)
 
Summary and Key Points: During the Cold War, the Soviet Union sought an edge in undersea warfare by designing the Lira-class submarines with titanium hulls. These submarines were intended to be faster, quieter, and capable of deeper dives than their American counterparts.


-However, despite the advantages of titanium—such as strength, lightweight, and corrosion resistance—the U.S. Navy chose not to follow suit. The decision was driven by the high cost, technical challenges, and welding difficulties associated with titanium. Instead, the U.S. focused on improving undersea warfare capabilities, such as developing advanced torpedoes.
 
-The Soviet Union only produced seven Lira-class submarines, which faced maintenance issues and were ultimately decommissioned. The U.S. Navy’s decision not to pursue titanium submarines proved to be wise, as the material’s benefits did not outweigh the significant drawbacks.

Well, it doesn't need to be lightweight if it's supposed to sink, as long as you can get it to float again.

Called the Alfa class by Nato, they were in commission 20-25 years (1971-1996). They were nuclear powered and carried torpedoes and/or mines. Their armament was roughly similar to late 1950s USN Skipjack class boats.

Other than 10 boats decommissioned by Clinton after ~18 years' service and a few more by GWB after a bit over 20 years' service, most Los Angeles class attack submarines served well over 30 years (a couple for 40), with 24 in service, approaching 40 years of service. The Los Angeles class were nearly triple the displacement of the Alfas and carry cruise missiles and Harpoon anti-ship missiles as well as torpedoes and/or mines.
