What was the name of the first nuclear powered submarine?

The first nuclear-powered submarine was the USS Nautilus, which made its historic maiden voyage on January 21, 1954. The Nautilus represented a significant technological advancement in naval engineering, as it was powered by a nuclear reactor, allowing it to stay submerged for extended periods without the need for surfacing to recharge batteries. This capability greatly enhanced the submarine's operational range and strategic versatility during the Cold War.

The success of the USS Nautilus paved the way for the development of more advanced military submarines and underscored the potential of nuclear propulsion in naval operations. This milestone in naval history marked the beginning of a new era in underwater warfare, fundamentally transforming naval tactics and capabilities.

In contrast, the other submarines listed in the options, while notable in their own right, were not the first to utilize nuclear power.
