Alfa: Russia's Cold War Submarine Wonder Weapon That NATO Feared

It could outrun torpedos. It could dive to record depths. But was this Soviet super sub simply a bust?
The Soviet Union began the Cold War well behind the United States in submarine technology. Although the Soviets acquired several of the most advanced German submarine types towards the end of the war, the United States had amassed a wealth of experience in submarine and antisubmarine practice from the Pacific War and the Battle of the Atlantic. Combined with other technological advantages, the United States leapt out to a significant lead in submarine tech (especially nuclear submarines) in the first two decades of the Cold War.
In particular, early Soviet nuclear submarines struggled to compete with the West in stealth and reliability. After the first few designs came to fruition, the Soviets decided to undertake a combination of brute force and extremely risky high technology. The brute-force part meant building a submarine that could move faster and dive deeper than any Western counterpart; the high-tech part meant innovative hull design, reactor design and material manipulation. The result was the Type 705 Lyra (known as Alfa in NATO), a submarine that the West regarded as a profound, if short-lived, threat to its undersea dominance.
Inception:
With the Lyra class, the Soviets sought to accomplish two goals. First, they wanted to produce a weapon capable of changing the character of naval warfare in the North Atlantic and the Arctic, a weapon that could threaten the overwhelming surface advantages of the NATO navies. Unlike their Western counterparts, which preferred multirole platforms, the Soviets were fine submarines dedicated to a single mission: the high-speed “interception” of NATO surface squadrons, especially carrier battle groups. Second, they wanted to jumpstart technological development, producing innovations that future submarines would incorporate, if only in piecemeal fashion. An incidental third goal was to force NATO navies to spend money and time adapting to the threat that the Lyras would present.
