Legend:

Laid down means that the ship's construction was officially started by laying down the keel (often just a single steel beam but could also mean the first of many pre-fabricated sections).

Launched means that the ship was launched from its shipyard, it then began its fitting out period (installation of smaller systems, weapons etc.) - in many yards the ships were launched very complete and needed little work afterwards.

Commissioned is when the navy takes the ship officially over and gives command of it to its new captain.
