When stationed in the base, captains and their crewmembers must check equipment on the boat on a weekly basis so that hazards can be discovered and fixed before the submarine leaves the base, said Peng Weihua, head of equipment supervision at the Qingdao base.
Ever since it was founded, the elite unit has been maintaining a low profile. Military observers and analysts have had few opportunities to look inside the deterrence force.
The official debut of the fleet was in 2009, when the PLA navy celebrated the 60th anniversary of its founding with a spectacular parade that included warships from China and 14 other nations.
Two nuclear submarines of the Chinese navy led the parade and attracted much attention from the international media and the public, with many foreign military observers speculating that China's nuclear submarine force had become strong and confident enough to show its muscle.
However, the force had chosen to continue a low profile until a recent open house for Chinese journalists.
"After more than 40 years of development, now is the time for us to show the world our determination and ability to safeguard peace and tell our people about this ‘mysterious' force," said Rear Admiral Li Yanming, political commissar of the Qingdao base.
