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.
