Final completion is still far into the future. What the article mentions, and is supported by the photos, is that the "outer hull" has been painted and the ship ready to be floated pierside. This is normal for ships in overhaul or fitting out. It can then spend an infinite period pierside until all work is completed.
Referring to the photos again, we can only see the outer hull and outer superstructure, the latter still in need of it's primer and paint. What we do not see are the interior spaces which in a warship are very complex with miles and miles of piping and wiring runs. Here is the root of why this ship is in the midst of delays and cost overruns. Problems we can not see in the photos, however, believe me they are there, inside this ship.
