Saint Petersburg, as the original birthplace of the Russian Navy, holds Russia's oldest shipyard—Admiralty Shipyard.
This is a three-century-old factory established in 1704, having survived Tsarist Russia, the Soviet Union, and Russia, constructing various vessels from sail battleships to nuclear submarines, and remains a crucial military shipyard producing nuclear submarines for the Russian Navy today.
It is also one of the only two Russian shipyards capable of fully assembling titanium alloy submarines.
Despite facing difficult times post-Soviet Union dissolution, once on the verge of bankruptcy and demise, this historic shipyard was revived with Russia's 2002 receipt of China's order for eight Kilo-class nuclear submarines, securing the construction quota for five of them.
