U.S. Navys Costliest Carrier Was Delivered Without Elevators to Lift Bombs

By Anthony Capaccio

November 2, 2018, 10:00 AM GMT+2


The $13 billion Gerald R. Ford aircraft carrier, the U.S. Navys costliest warship, was delivered last year without elevators needed to lift bombs from below deck magazines for loading on fighter jets.

Previously undisclosed problems with the 11 elevators for the ship built by Huntington Ingalls Industries Inc. add to long-standing reliability and technical problems with two other core systems -- the electromagnetic system to launch planes and the arresting gear to catch them when they land.


The Advanced Weapons Elevators, which are moved by magnets rather than cables, were supposed to be installed by the vessels original delivery date in May 2017. Instead, final installation was delayed by problems including four instances of unsafe uncommanded movements since 2015, according to the Navy.

While progress was being made on the carriers other flawed systems, the elevator is our Achilles heel, Navy Secretary Richard Spencer told reporters in August without providing details.

Technology Risk
The elevator system is just another example of the Navy pushing technology risk into design and construction -- without fully demonstrating it, said Shelby Oakley, a director with the U.S. Government Accountability Office who monitors Navy shipbuilding.

Problems with the elevators add to questions about the Navys plan to bundle the third and fourth carriers in the $58 billion Ford class into one contract. Its part of the services push to expand its 284-ship fleet to 355 as soon as the mid-2030s.

Congress gave the Navy permission for the two-at-once contract in this years defense spending and policy bills despite the unresolved technical issues and the lack of a Navy estimate so far of how much money it would save the service. Deputy Defense Secretary Pat Shanahan continues to review the contracting plan.

The Navy says that the first carrier will be fully combat-capable, including the elevators, by July -- the end of its current 12-month pier-side shakedown period in Virginia.

Navy weapons buyer James Geurts cited what he called considerable progress on the Ford, including on the elevators, in a July 6 memo to Pentagon acquisition head Ellen Lord.

The Navy in May requested permission from Congress in May to increase the Fords cost cap by $120 million, partly to fix elevator issues to preclude any effect on the safety of the ship and personnel. The safety issues related to the uncommanded movements, the Navy said in an email.

First-in-Class Issues
Beci Brenton, a spokeswoman for Newport News, Virginia-based Huntington Ingalls, said all the elevators are installed. She said the weapons elevator is among the most advanced technologies being incorporated into the carrier and its completion has been delayed due to a number of first-in-class issues, Brenton said.

We are committed to working through the remaining technical challenges, she said.

William Couch, a spokesman for the Naval Sea Systems Command, said the elevators are in varying levels of construction and testing.

Six are far enough along to be operated by the shipbuilder, and testing has started on two of those, he said. All 11 should have been completed and delivered with the ship delivery, according to Couch.

He said the contractor has corrected all issues, including the four uncommanded movements over the last three years that were discovered during the building, operational grooming, or testing phases.

Elevator of Tomorrow
A November 2010 program on PBSs Nova science series extolled the Elevator of Tomorrow being developed by Federal Equipment Co., a Cincinnati-based subcontractor to Huntington Ingalls.

In the not-too-distant future the Advanced Weapons Elevator will be lifting bombs to the flight deck of a new aircraft carrier, the narrator said. If it survives the rigors of Navy life, someday we might all be passengers on elevators powered like this one.

Doug Ridenour, president of Federal Equipment Co., said the elevators key technologies have been consistently demonstrated for years in a test unit in the companys plant and any programming or software-related issues have been fixed.

But shipboard integration involves many other technology insertions not controlled by his company, he said.
