The first USS "Pocahontas, a screw steamer built at Medford, Massachusetts in 1852 as "City of Boston", and purchased by the Navy at Boston, Massachusetts on 20 March 1855, was the first United States Navy ship to be named for Pocahontas, the Algonquian wife of Virginia colonist John Rolfe.
 She was originally commissioned as USS "Despatch — the second U.S. Navy ship of that name — on 17 January 1856, with Lieutenant T. M. Crossan in command, and was recommissioned and renamed in 1860, seeing action in the American Civil War.

 In July 1905, the shipyard housed the Russian battleship "Potemkin" and refloated her after she was half scuttled by her mutinous crew.
 The first ship ever constructed by the shipyard and launched to sea on May 31, 1936 was a 12 m long yacht named "Crai Nou", designed and built by Alexandru Theodoru a student at the Naval School in Constanţa and graduate of the French Naval School.
 During World War II, the shipyard provided repair and maintenance to the Italian flotilla of midget submarines operating in the Black Sea.
 Together with the Galați shipyard, it also rebuilt, maintained and repaired numerous German R-boats during the War.
 1950 the shipyard began to construct ships, pontoons, tugboats and towboats.
 In 1975 the shipyard constructed one bulk carrier of  DWT which was the first large ship ever constructed in Romania.
The second USS Portsmouth was a wooden sloop-of-war in the United States Navy in service during the mid-to-late 19th century.
 She was designed by Josiah Barker on the lines of a French-built privateer, and built at the Portsmouth Navy Yard, directly across the Piscataqua River from Portsmouth, New Hampshire.
 She was described as an improvement over the USS "Saratoga" built in the same shipyard a year earlier.
 The "Portsmouth" was launched on 23 October 1843 and commissioned on 10 November 1844, with Commander John Berrien Montgomery in command.
The Black Sea Shipyard (Ukrainian: Чорноморський суднобудівний завод ; Russian: Черноморский судостроительный завод ) is located in Mykolaiv, Ukraine.
 It was founded in 1895 by Belgian interests and began building warships in 1901.
 At the beginning of World War I in 1914, it was one of the largest industrial facilities in the Russian Empire.
 The shipyard was moribund until the Soviets began building up the fleet in the 1930s and it began building surface warships as well as submarines.
 The yard was badly damaged during World War II and took several years to be rebuilt.
 Surface warship construction temporarily ended in the mid-1950s before being revived in the mid-1960s and submarines were last built in the yard in late 1950s.
 The Black Sea Shipyard built all of the Soviet Navy's aircraft carrying ships and continues to build large commercial ships.
