See the newest American aircraft carrier under construction
The USS John F. Kennedy, the second of the Navy’s Gerald R. Ford-class advanced nuclear-powered aircraft carriers, reached 70% completion in late February 2018, according to shipbuilder Huntington Ingalls.
Like the first-in-class Gerald R. Ford, the Kennedy’s construction is being done with a modular technique, in which smaller parts of the ship are welded together to form larger chunks, called superlifts, that are then hoisted together.
The latest construction milestone came when crews at Huntington Ingalls’ Newport News Shipbuilding dropped an 888-ton superlift — a 171-foot long, 92-foot wide section composed of berthing areas, electrical-equipment rooms, and workshops — into place between the carrier’s bow and midship.
Below, you can see footage of the superlift being moved into place by the company’s 1,157-ton gantry crane at Dry Dock 12.
The latest superlift took 18 months to construct and it “represents one of the key build-strategy changes for Kennedy: building superlifts that are larger and more complete before they are erected on the ship,” Mike Butler, the program director for the Kennedy, said in a Huntington Ingalls press release.
Construction on the Kennedy started in February 2011, with the “first cut of steel” ceremony at Newport News. The ship’s keel was laid in August 2015, and it hit the 50%-constructed mark in June 2017, when crews moved the 1,027-ton lower-stern section — containing rudders, tanks, steering-gear rooms, and electrical-power-distribution rooms — into place.
“We are pleased with how construction on the Kennedy is progressing, and we look forward to additional milestones as we inch closer to christening of the ship,” Butler said in the February 2018 release. The Kennedy is set to launch in 2020.
Like the Ford, the Kennedy contains an array of advanced features, including the Electromagnetic Launch System and Advanced Arresting Gear, both of which assist with launching and landing aircraft. (The Ford lacked one notable feature: urinals.)
The Ford, however, was delivered to the Navy two years later than planned and cost about $12.9 billion — 23% more than originally estimated.
The Government Accountability Office warned in summer 2017 that the $11.4 billion budget set for the Kennedy was unreliable and didn’t address lessons learned during the building of the Ford. The Pentagon partially agreed with those conclusions.
In August 2017, Huntington Ingalls completed the first-cut-of-steel ceremony for the third Ford-class carrier, the USS Enterprise.
