Shipyard
A shipyard (also called a dockyard) is a place where ships are built and repaired. These can be yachts, military vessels, cruise liners or other cargo or passenger ships. Dockyards are sometimes more associated with maintenance and basing activities than shipyards, which are sometimes associated more with initial construction. The terms are routinely used interchangeably, in part because the evolution of dockyards and shipyards has often caused them to change or merge roles.
Secretary of The Navy Shipyards
The Astilleros de la Secretaría de Marina (Mexican Secretary of The Navy Shipyards), are also known as ASTIMAR. The yards are dependent on the Mexican General Directorate of Naval Construction of the Mexican Navy, which carries out various types of naval construction and repairs in the Mexican territory.
