Reactor incident

On December 28, 1978, while in the Pacific Ocean, K-171 had a reactor failure. Radiation exposure resulted in the deaths of three crew members on board.[3]

Retirement

Like most Soviet Delta I and Delta II-class submarines that were in service after the Cold War, the submarine was scrapped to comply with new treaties. It was decommissioned from the Russian Navy in 2003.[4]
