The '''Philadelphia Naval Shipyard''' was the first [[United States Navy]] [[shipyard]] and was historically important for nearly two centuries.<ref>{{cite web |url=http://www.philly-yardbird.com/ |title=Philadelphia Naval Shipyard ex-YardBird |website=www.philly-yardbird.com}}</ref>

Construction of the original Philadelphia Naval Shipyard began during the [[American Revolution]] in 1776 at [[Front Street (Philadelphia)|Front]] and Federal Streets in what is now the [[Pennsport, Philadelphia|Pennsport]] section of Philadelphia. In 1871, it was replaced by a new, much larger yard developed around facilities on [[League Island]], at the confluence of the [[Delaware River|Delaware]] and [[Schuylkill River|Schuylkill]] rivers. The Navy Yard expansion stimulated the development over time of residences and businesses in [[South Philadelphia]], where many shipyard workers lived. During [[World War II]], some 40,000 workers operated on shifts around the clock to produce and repair ships at the yard for the war effort.

The U.S. Navy ended most of its activities at the shipyard in the 1990s, closing the base after recommendations by the [[Base Realignment and Closure]] commission. In 2000, the Philadelphia Industrial Development Corporation, on behalf of the City of Philadelphia, acquired it and began to redevelop the land. First called '''Philadelphia Naval Business Center''', it is now known as '''The Navy Yard'''. It is a large mixed-use campus where nearly 15,000 people are employed by more than 120 companies representing a mix of industries, including cell therapy production facilities, global fashion companies, and a commercial shipyard. The U.S. Navy still operates a [[Naval Inactive Ship Maintenance Facility]] and a few engineering activities at the site.

===18th and 19th centuries===

The yard has its origins in a commercial shipyard founded in 1776 on [[Philadelphia]]'s [[Front Street (Philadelphia)|Front Street]] on the [[Delaware River]]; it was designated an official [[United States Navy]] site in 1801.

From 1812 until 1865, it was a large ship production center. The first ship launched to the water was the [[USS Franklin (1815)|USS ''Franklin'']]. This event was watched by more than 50,000 spectators. The rapid development of other shipbuilding companies pledged Philadelphia to improve production processes. This was the first shipyard in the world to use floating dry docks in the building process to improve an operating time of the ships.<!-- unclear - improve delivery time in producing ships? --><ref name=TheNavyYard>{{cite web|title=The Navy Yard Philadelphia|url=http://www.navyyard.org/about-the-campus/history|access-date=8 July 2016}}</ref>

After the advent of ironclad warships made the site obsolete, new facilities were built in 1871 on [[League Island]] at the confluence of the [[Delaware River|Delaware]] and [[Schuylkill River|Schuylkill]] rivers.<ref>{{Cite web |last=Hutto |first=Cary |date=2012-08-22 |title=League Island before the Navy Yard {{!}} Historical Society of Pennsylvania |url=https://hsp.org/blogs/fondly-pennsylvania/league-island-before-the-navy-yard |url-status=live |archive-url=https://web.archive.org/web/20220422151636/https://hsp.org/blogs/fondly-pennsylvania/league-island-before-the-navy-yard |archive-date=2022-04-22 |access-date=2023-01-12 |website=Historical Society of Pennsylvania}}</ref>

Beginning in the early 19th century, many Philadelphia workers agitated for a reduction in the arduous twelve-hour workday. Prior to 1835, the workday in the Philadelphia Navy Yard was sunrise to sunset, with time off for breakfast.<ref>Sharp, John G.M., ''The Philadelphia Navy Yard in 1835 & the Birth of the Ten-Hour Day'', http://www.usgwarchives.net/va/portsmouth/shipyard/sharp/philany.html {{Webarchive|url=https://web.archive.org/web/20220301151126/http://www.usgwarchives.net/va/portsmouth/shipyard/sharp/philany.html |date=1 March 2022 }}</ref> In the summer of 1835 Philadelphia Navy Yard shipwrights, joiners and other workers led the effort to reduce the workday by combining the direct action of a strike, with political pressure to the executive branch. After first seeking workday reduction by a request to the Secretary of the Navy via shipyard Commandant Commodore James Barron, on 29 August 1835 they appealed directly to President [[Andrew Jackson]]. Commodore Barron endorsed his workers' request with the following acknowledgment "I would respectfully observe – Seems to be inevitable, sooner or later, for as the working man are seconded by all the Master workmen, city councils etc. there is no probability they will secede from their demands."<ref>{{cite web | url=http://genealogytrails.com/penn/philadelphia/phlbios_a-b.html | title=Philadelphia Pennsylvania Biographies }}</ref>

Their petition was granted and on 31 August 1835 the president ordered the Secretary of the Navy to grant the ten-hour work day, effective 3 September 1835. However, the change was applicable only to the Philadelphia Navy Yard. On 29 August 1836, a committee of Philadelphia Navy Yard mechanics appealed to President Andrew Jackson to extend the law, 
<blockquote>"The Committee are sure that if the example is set in Philadelphia it will be [illegible] required in other places and they will not attempt to disguise the pleasure it would give them as Citizens and as Workingmen to see a reformation taking place under the auspices of the Government."<ref>Sharp, Ibid</ref></blockquote> 
It was five years before the ten-hour day was extended to all government employees engaged in manual labor; this was accomplished via an executive order by President [[Martin Van Buren]] on 31 March 1840.<ref>{{Cite book|title=Our Own Time: A History of American Labor and the Working Day|last1=Roediger|first1=David R|last2=Foner|first2=Phillip Sheldon|publisher=Verso|year=1989|isbn=0860919633|location=London|pages=[https://archive.org/details/ourowntime00davi/page/39 39–41]|url-access=registration|url=https://archive.org/details/ourowntime00davi/page/39}}</ref>

===20th century===
[[File:Mustin Field NAMC Phili NAN9-48.jpg|thumb|An aerial view of [[Henry C. Mustin Naval Air Facility|Mustin Field]] and the shipyard with [[John F. Kennedy Stadium (Philadelphia)|Philadelphia Municipal Stadium]] visible behind the runways in September 1948]]
The [[Naval Aircraft Factory]] was established at the League Island site in 1917. Just after of the end [[World War I]], a 350-ton capacity [[Crane (machine)|hammerhead crane]] was ordered for the yard. Manufactured in 1919 by the [[McMyler-Interstate Company]] in [[Bedford, Ohio]], the crane was called the '''League Island Crane''' by its builder. Weighing 3,500 tons, the crane was shipped to the yard in sections. At the time, it was the world's largest crane.<ref name=bhs>"McMyler-Interstate Co.." Bedford Historical Society. N.p., n.d. Web. 19 June 2010. <http://www.bedfordohiohistory.org/build/mcmyler.php>.</ref> For many years, the "League Island Crane" was the Navy's largest crane.{{citation needed|date = March 2016}}

[[Mustin Field]] opened at the Naval Aircraft Factory in 1926 and operated until 1963.{{citation needed|date = March 2016}}

The shipyard's greatest period came in [[World War II]], when the yard employed 40,000 people who built 53 ships and repaired 574. During this period, the yard built the famed battleship [[USS New Jersey (BB-62)|''New Jersey'']] and its 45,000-ton sister ship, [[USS Wisconsin (BB-64)|''Wisconsin'']]. In the Naval Laboratory, [[Philip Abelson]] developed the liquid thermal diffusion technique for separating [[uranium-235]] for the [[Manhattan Project]].<ref>{{Cite journal|date=24 January 2011|title=Resource Letter MP-2: The Manhattan project and related nuclear research|url=http://aapt.scitation.org/doi/10.1119/1.3533209|journal=American Journal of Physics|volume=79|issue=2|pages=151–163|doi=10.1119/1.3533209|issn=0002-9505|last1=Reed|first1=B. Cameron|bibcode=2011AmJPh..79..151R|s2cid=209834575 |url-access=subscription}}</ref>

The memorial chapel to the [[Four Chaplains]] is located on the grounds.<ref name="alm2015">{{cite news|last1=Grills|first1=Matt|title=More than a story|url=http://www.legion.org/magazine/225769/more-story|access-date=30 March 2016|work=American Legion Magazine|date=20 January 2015}}</ref>

After World War II, the workforce dropped to 12,000, as the Navy stabilized its fleet. In the 1960s, the Navy began to contract with private companies to construct new ships. The yard built its last new ship, the command ship [[USS Blue Ridge (LCC-19)|''Blue Ridge'']], in 1970.<ref name=sbhistory/>

Because of foreign competition and reduced needs due to the end of the [[Cold War]], the defense [[Base Realignment and Closure]] Commission recommended closure of the yard in 1991. The city and state struggled to keep the facility operational, and the planned closing was unsuccessfully litigated to the US Supreme Court in ''[[Dalton v. Specter]]''. When the yard finally closed in 1995, it cost the region 7,000 jobs. This followed years in which the region had lost industrial jobs to restructuring and movement of manufacturing overseas. US Senator [[Arlen Specter]] charged that the [[United States Department of Defense|Department of Defense]] did not disclose the official report on the closing. This resulted in a controversy that led to further legal disputes, but no actions.

Since its transfer from the government to the City of Philadelphia, the west end of property has been leased to [[Aker Kværner]], a tanker and commercial shipbuilding firm.{{citation needed|date = March 2016}}

==Notable ships==
* [[USS Franklin (1815)|''Franklin'']], a 74-gun [[ship of the line]] launched in 1815, the first vessel laid down at the shipyard. It was started as part of the United States' massive construction program of ships for the [[War of 1812]], including twelve ships completed at [[Sackets Harbor, New York]] for use on the [[Great Lakes]].
* [[USS New Jersey (BB-62)|''New Jersey'']], an {{Sclass |Iowa|battleship}} used in [[World War II]] and later
* [[USS Wisconsin (BB-64)|''Wisconsin'']], the last keel laid for a completed battleship of the [[United States Navy]], 25 January 1941<ref>BB-64 was launched and commissioned before BB-63, in spite of a later keel-laying.{{citation needed|date = March 2016}}</ref>
* [[USS Blue Ridge (LCC-19)|''Blue Ridge'']], an amphibious command ship. This was the last vessel built at the shipyard.

==Atlantic Reserve Fleet, Philadelphia ==
'''Atlantic Reserve Fleet, Philadelphia''' opened at the Philadelphia Naval Shipyard in 1946 to store the many surplus ships after World War II. As part of the [[United States Navy reserve fleets]], the fleet "mothballed" ships and submarines. Many of the ships in the fleet were reactivated for the [[Korean War]] and some for the [[Vietnam War]].<ref>[https://www.youtube.com/watch?v=MqNKreV8KGg youtube.com The USN Mothball Fleet - Storing up for a rainy day]</ref><ref>[https://www.thetravel.com/visit-the-philadelphia-naval-shipyard-mothball-fleet/ This Is What's Left Of Philadelphia's Once Mighty Mothball Fleet By Aaron Spraym Feb. 20, 2022]</ref> The control of the [[reserve fleet]] was later transferred to the [[Naval Inactive Ship Maintenance Facility]] (NISMF). The {{USS|Chandeleur|AV-10}} was used as a [[barracks ship]] for the crew at the Atlantic Reserve Fleet, Philadelphia.<ref>[https://www.youtube.com/watch?v=uHzD1habYBo youtube.com, The Mothball Fleet]</ref><ref>[https://www.history.navy.mil/our-collections/photography/numerical-list-of-images/nara-series/80-g/80-G-600000/80-G-668656.html US Navy Reserve Fleet Basin, Philadelphia]</ref><ref>[https://www.loc.gov/resource/hhh.pa3415.photos/?sp=3 LOC Reserve Fleet, Philadelphia]</ref><ref>''USS Chandeleur AV-10: Sailing Airbase for Flying Boats'', by Turner Publishing Company</ref>

==League Island after the naval shipyard==
The City of Philadelphia became the landlord and owner of the League Island site in March 2000, when the Philadelphia Authority for Industrial Development (PAID) took title to roughly 1,000 acres from the Navy.  Today, the site is operated as a mixed-use industrial park under the name "The Navy Yard". The Philadelphia Industrial Development Corporation (PIDC) manages the planning, operation, and development of The Navy Yard on behalf of PAID and the City of Philadelphia; its offices are now located at The Navy Yard.

A comprehensive master plan was completed in 2004 to redeveloped the former industrial yard to a mixed-use campus.{{citation needed|date = March 2016}} It proposed adaptive reuse of some Navy buildings as office space; maintenance of buildings and campus elements with strong historic interest, such as the Navy Yard Marine Parade Grounds; and construction of new buildings for offices and other purposes as needed for new tenants. This construction has been in the section called the Corporate Center.

As of 2010, US Navy activities include [[Naval Support Activity Philadelphia]], the Naval Surface Warfare Center Ship Systems Engineering Station, Naval Facilities Engineering Command Mid-Atlantic Public Works Department Pennsylvania (NAVFAC MIDLANT PWD PA), and the [[Naval Inactive Ship Maintenance Facility]] (NISMF). This last  stores decommissioned and mothballed warships and auxiliary naval vessels.

[[File:Broad Street Navy Yard Marine parade grounds.jpg|220px|right|thumb|Navy Yard parade grounds in 2024]]
The Navy Yard is now the site of 120 companies with 10,000 employees. New businesses continue to be attracted to the campus, and existing ones expand. Clothing retailer and manufacturer [[Urban Outfitters]] consolidated its Philadelphia headquarters on the site. [[Tasty Baking Company]], makers of [[Tastykake]]s, has moved their bakery to the 26th Street side of The Yard. Other occupants include Rittenhouse Ventures, [[Hanwha Philly Shipyard]], [[Rhoads Industries|Rhoads Industries Inc.]] in Navy Building 57,<ref>{{Cite press release|url=https://www.bizjournals.com/philadelphia/press-release/detail/5916/ccg-pace-funding-llc|title=CCG PACE Funding Closes $15 Million in C-PACE Financing in Philadelphia|access-date=2021-09-07|website=Philadelphia Business Journal}}</ref> Energy Efficient Buildings Hub (EEB Hub), [[RevZilla.com]], and Mark Group, Inc.{{citation needed|date = March 2016}}

In January 2013, PIDC announced its intention to increase the number of apartments on site for employees (near 1,000) and additional infrastructure development. This is made possible by the public financing of shipyards and investments of private companies. According to the plan for 2013, the number of employees at the shipyard amount to around 30,000 people.<ref>{{cite web|title=Business booms at old naval shipyard in Philadelphia|website=[[Fox News]] |date=25 March 2015|url=https://www.foxnews.com/us/business-booms-at-old-naval-shipyard-in-philadelphia|access-date=8 July 2016}}</ref>

In March 2013, the Canadian Pacific – Bulkmatic Transport transload site on Langley Ave was closed.

The [[Athletic Base Ball Club of Philadelphia]] hosts the annual Philadelphia Base Ball Fair & Exhibition at the Navy Yard Marine Parade Grounds.{{citation needed|date = March 2016}}
