The ceremonies involved in naming and launching naval ships are based in traditions thousands of years old.

There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching." The oldest, most familiar, and most widely used is the end-on launch, in which the vessel slides, usually stern first, down an inclined slipway. The side launch, whereby the ship enters the water broadside, came into 19th-century use on inland waters, rivers, and lakes, and was more widely adopted during World War II. The third method is float-out, used for ships that are built in basins or dry docks and then floated by admitting water into the dock.

A Babylonian narrative dating from the 3rd millennium BC describes the completion of a ship:

Openings to the water I stopped;
I searched for cracks and the wanting parts I fixed:
Three sari of bitumen I poured over the outside;
To the gods I caused oxen to be sacrificed.

Elon Musk (born June 28, 1971) is a South African-born American business magnate, engineer and inventor. He is best known for co-founding SpaceX, Tesla Motors and X.com, which later became Paypal after acquiring the service. He is currently the CEO and Chief Designer of SpaceX, CEO and Product Architect of Tesla Motors and Chairman of SolarCity. While at those companies, Musk co-designed the first viable electric car of the modern era, the Tesla Roadster, a private successor to the Space Shuttle, Falcon 9/Dragon, and the world's largest Internet payment system, PayPal.

Elon Musk was born in Pretoria, South Africa, the son of a Canadian-American mother and a South African father. His maternal grandfather was from Minnesota, and had moved to Saskatchewan, where Musk's mother was born. His father is an engineer and his mother is an author, nutritionist and model, appearing on the cover of New York Magazine in 2011 and a Time Magazine supplement in 2010.

Musk bought his first computer at age 10 and taught himself how to program; by the age of 12 he sold his first commercial software for about $500, a space game called Blastar.
