The Fastest Submarine Ever Built — And Why It Failed

Why is the fastest combat submarine ever built still the fastest — decades later — and nobody tried to beat it? Why would a navy retire a weapon that nothing in the world could catch? How can speed be a fatal flaw? And why would sailors nickname their own ship "Port Queen" — a vessel designed to be the most feared machine in the ocean? The Cold War leaves long shadows, and much of what surrounded the Alfa Class, Project 705 Lira, remains disputed or classified. This is an engineering breakdown — not a history verdict. The numbers don't lie. The rest is still smoke. RIGSILENT explores the engineering, history, and psychology of submarines — told with the precision they deserve.
