The video is a historical presentation on the Soviet Project 705 'Alfa' attack submarines. It explains how designers used titanium hulls and lead–bismuth reactors to produce tiny, fast boats capable of ~40+ knot bursts and extreme depths, and covers the tradeoffs: superb tactical performance, small crews (~30–35), and high acceleration contrasted with costly construction, reactor maintenance hazards, and limited numbers (seven boats built), which kept the class from revolutionizing naval warfare.
Project 705 'Alfa' submarines (NATO: Alfa) used titanium hulls and lead–bismuth liquid‑metal–cooled reactors to achieve extreme performance: submerged speeds of about 40–41 knots and claimed test depths on the order of ~1,000 meters.
Built to outrun torpedoes and dive deeper than any weapon, the Alfa Class was the most ambitious submarine the Soviet Union ever built. It was supposed to fundamentally change naval warfare and render the American submarine fleet obsolete.
