One Russian Cruise Missile Submarine Made History (By Sinking Twice)

Robert Farley

Security,

It sank twice.

The ensuing disaster was altogether predictable. Suvorov was unaware that the overhaul process had locked the ventilation system open. Instrumentation on the boat was not properly set up, and in any case the crew had little experience with the boat, or with each other. The captain ordered a test dive, which resulted in an extremely fast descent because of misunderstandings about the ballast tanks. At that point, one compartment of the boat began to flood quickly. Response procedures were slow because of crew inexperience, and fourteen sailors quickly died. Shortly afterward, the boat hit bottom, about 160’ below the sea.

The Cold War saw numerous submarine accidents, especially on the Soviet side. For much of its existence, the USSR tried to maintain a world-beating military with a second-rate economy. Throughout the era, the Soviets struggled to maintain their magnificent weapons of war. In the effort to close this gap, the crews of Soviet submarines often paid with their lives.

But only one submarine had the poor luck to sink twice.

The Charlie class (Project 670) was the third class of cruise-missile submarines (SSG) deployed by the Soviet Union, and the second to use nuclear propulsion (SSGN). The Soviet Navy expected to use early SSGs and SSGNs to attack American land targets, primarily cities and naval bases, with conventional and nuclear warheads. The cruise missiles of the time lacked sophisticated guidance mechanisms, making attacks against the interior impossible. Over time, the improvement of radar-homing technology (as well as improvements in ballistic-missile technology) allowed the Soviets to reconceptualize the use of cruise missiles. The Echo II class, the immediate predecessor to the Charlies, were built with an anti-shipping role in mind. Antiship missiles appealed to the Soviets because of the noise of their submarines; the Soviet Navy did not expect that its boats could close within sufficient range to hit American capital ships with torpedoes.
