History of Drydock Number One
Drydock Number One has been the mainstay of the Norfolk Naval Shipyard since its construction began in 1918. It was built to accommodate the largest battleships of the time.
The drydock was designed to be 1,000 feet long and 165 feet wide, with a depth of 35 feet. These dimensions allowed it to accommodate the massive battleships of the era.
The drydock was officially commissioned in 1923 and has since played a crucial role in the repair and maintenance of numerous naval vessels.
Construction and Opening
Construction on Drydock Number One began in 1919 and was completed in 1920, taking only a year to build.
The drydock was designed by the renowned naval architect, John L. Gillingham, who was responsible for several notable shipbuilding projects in the United States.

It was built by the Newport News Shipbuilding and Drydock Company, a prominent shipyard at the time.
The drydock was initially used to repair and maintain the US Navy's fleet, and it quickly became an essential facility for the naval base.
The drydock's construction was a significant undertaking, requiring over 3,000 tons of steel and 1,000 tons of concrete.
Notable Repairs and Upgrades
Drydock Number One underwent a major overhaul in 1935, which included replacing its original steam engines with more efficient diesel engines.
This upgrade significantly improved the drydock's capacity and reduced operating costs.
In 1942, the drydock received a new set of cranes, increasing its ability to lift and move heavy equipment.
The drydock's hull was also repaired and reinforced during this time to withstand the stresses of wartime operations.
After the war, the drydock underwent a major modernization program, which included the installation of new electrical and mechanical systems.
This upgrade allowed the drydock to operate more efficiently and safely, and it continued to serve as a vital facility for naval repairs and upgrades.
In 1958, the drydock was renovated to accommodate larger ships, including aircraft carriers and submarines.
The renovation included the installation of a new floating dock and improved crane systems.
Historical Significance
Drydock Number One's historical significance is rooted in its construction during the American Civil War. The dock was built between 1861 and 1862.
It was a massive undertaking that required the labor of over 1,000 workers to complete. The dock's size and complexity were unprecedented at the time.
The dock was designed to accommodate the largest ships of the era, including the USS Monitor, which was built in the adjacent shipyard. The Monitor played a pivotal role in the Battle of Hampton Roads.
The dock's construction was overseen by engineer and naval architect, John Lenthall. Lenthall's expertise was instrumental in bringing the project to fruition.
The dock's significance extends beyond its construction, as it played a crucial role in the Union Navy's efforts during the Civil War.
Impact and Significance
Drydock Number One at Norfolk Naval Shipyard is a significant facility, with its construction beginning in 1904 and taking several years to complete. It was finally completed in 1910.
The shipyard's drydock was used for the first time in 1910, with the USS South Carolina being the first ship to be repaired and maintained there. This marked the beginning of a long history of ship repair and maintenance at the facility.
The drydock's size and depth allowed for the repair of large ships, including battleships and aircraft carriers, which was crucial for the US Navy during World War I and World War II.
