Two of the first submarines to serve in the US Navy, the USS Porpoise and the USS Shark, both of the Plunger or A class, were built in nearby Elizabethport, New Jersey at the Crescent Shipyard. Both were commissioned in September 1903, and both spent time in the Brooklyn Navy Yard dry docks. Only one year after being put to sea, they were sent to Brooklyn for extensive maintenance and refitting. In 1908, the Porpoise and the Shark were disassembled and transported via the Suez Canal to the Philippines, where they served until being decommissioned in 1919.
The next tour of the Brooklyn Navy Yard will be Sunday, September 13, and tickets are still available (at the time of this posting, so act fast!)
