; it was designated in 1801 as an official

site in 1801. From 1812 until 1865 it was a big ship production center. The first ship launched to the water was the 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. After the advent of ironclad warships made the site obsolete, new facilities were built in 1871 on

at the confluence of the Delaware and Schuylkill rivers. From early in the nineteenth 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. 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

. 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." 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,

"The Committee are sure that if the example is set in Philadelphia it will be llegiblerequired 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."

It was 5 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

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. 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
