Chinese submarine Changzheng 1, type 091 nuclear submarine
The Chinese submarine Changzheng 1 is a historic warship now serving as a museum exhibit at the Qingdao Naval Museum. Its gray, streamlined hull features a compact conning tower and displays the functional design of the 1970s, with six torpedo tubes at the front and an overall length of approximately 98 meters.
The submarine was built in the late 1960s, launched in 1970, and entered service in 1974 as China's first nuclear-powered naval vessel. It represented a major breakthrough for Chinese military technology during a period when the country had to develop its nuclear capabilities without Soviet assistance.
The submarine is named Changzheng 1, after a famous Chinese space rocket series. For many people, this vessel represents their country's transition to a modern naval power and inspires pride in the engineering achievements made during this transformative period.
The submarine is located at the Qingdao Naval Museum and is accessible during museum hours. Visitors should wear comfortable shoes, as the walkways are narrow and the interior features many steps and low passages.
The vessel was notorious for its loud acoustic signature underwater, making it easy for adversaries to detect compared to later, quieter models. Despite this limitation, the ship proved reliable over many years and played a role in advancing China's submarine fleet development and modern detection systems.
