The Hotel-class submarines were the first Soviet nuclear subs equipped with ballistic missiles. The Hotel design was very similar to that of the November class, but with a compartment added to accommodate missiles.

The K-19, nicknamed “The Widowmaker” and “Hiroshima,” was the first in the Hotel class and experienced a variety of fatal accidents.
