That's really fast. Just two years ago we saw satellite images from the empty dry dock. Now she is ready to be launched. It will probably take another two years for her to be fully deploy-able.
My guess is the ship will run builder's sea trial in late 2018, delivered to the navy by end of 2018, navy trials including deck operation, arrested landing, etc, through the first half of 2019, and training throughout 2019, with 1-2 work up cruises, and ready for actual operation sometime first half of 2020.
