The United States Navy (USN) is the naval warfare service branch of the United States Armed Forces and one of the seven uniformed services of the United States. It is the largest and most capable navy in the world and it has been estimated that in terms of tonnage of its active battle fleet alone, it is larger than the next 13 navies combined, which includes 11 U.S. allies or partner nations. with the highest combined battle fleet tonnage and the world's largest aircraft carrier fleet, with eleven in service, and two new carriers under construction. With 319,421 personnel on active duty and 99,616 in the Ready Reserve, the Navy is the third largest of the service branches. It has 282 deployable combat vessels and more than 3,700 operational aircraft as of March 2018, making it the second-largest air force in the world, after the United States Air Force.

Alameda is a city in Alameda County, California, United States. It is located on Alameda Island and Bay Farm Island, and is adjacent to and south of Oakland and east of San Francisco across the San Francisco Bay. Bay Farm Island, a portion of which is also known as "Harbor Bay Isle", is not actually an island, and is part of the mainland adjacent to the Oakland International Airport. The city's estimated 2017 population was 79,928. Alameda is a charter city, rather than a general law city, allowing the city to provide for any form of government. Alameda became a charter city and adopted a council–manager government in 1916, which it retains to the present.
