William Cramp & Sons

William Cramp was born in the Kensington district of Philadelphia in 1807. In 1855, his sons Charles Henry (born 1828)^[1] and William C., became partners with their father. In 1872, his other sons Samuel H., Jacob C., and Theodore were taken into the firm. The company was incorporated under the name "The William Cramp and Sons' Iron Shipbuilding and Engineering Company."^[2]

The pilot boat Thomas Howard was built by the Cramp shipyard in 1870 for the Delaware Bay & River pilots. She was one of the Philadelphia port's fastest pilot boats.^[3]

In 1890 the company built the battleships USS Indiana and USS Massachusetts, armored cruiser USS New York, and protected cruiser USS Columbia. Three of these ships took a part in the defeat of the Spanish fleet in 1898 at Santiago de Cuba. The victory in this battle heralded America's emergence as a great power.^[4] In 1896 Cramps united their artillery arm, the Driggs-Schroeder Ordnance Company, with its main competitor Hotchkiss Gun Company and a projectile manufacturer from Massachusetts into American Ordnance Company.^[5] The American Shipping and Commercial Corporation bought the yard in 1919 but closed it in 1927^[6] as fewer ships were ordered by the U.S. Navy after the adoption of the Naval Limitations Treaty in 1923.

 

In 1940, the Navy spent $22 million to reopen the yard as Cramp Shipbuilding to build cruisers and submarines. Cramp used the long slipways to construct two submarines at a time, with the intention of launching them simultaneously. However, the shipyard's submarine construction program was not especially successful, as poor management hindered the delivery of the boats.^[7] The first delivery was made two years after keel laying, and fitting out was then done by Portsmouth Navy Yard. The best construction time for a submarine was 644 days.^[8]

Cramp closed in 1947 and the site, on the Delaware River in Philadelphia's Port Richmond neighborhood, was turned into a residential estate in early 2020s.

 

 

• SS Valencia, a small ocean liner built for the Red D Line in 1882.^[9] She was wrecked on the coastline of Vancouver Island, on January 22, 1906, killing around 116 people.^[10] Valencia's loss is considered one of the worst shipwrecks in the region known as the Graveyard of the Pacific.^[11][12]
• Atalanta (1883) Atalanta was built for financier Jay Gould in the same year that the American Yacht Club was founded.
• SS Philadelphia, a small ocean liner of 2,499 tons built for the Red D Line in 1885

On 22 April 1943, Oklahomans were outraged, having just learned that the Japanese had executed the captured American pilots from Jimmy Doolittle's bombing raid over Tokyo. That same day, booths were set up in Oklahoma City with a goal to sell $40 million in War Bonds to fund the construction of a cruiser. That goal was topped by $5 million when the booths closed that night. CL-91 then became the USS Oklahoma City.
