28 Jun 19 - 3 Apache AH MK1 Aircraft of 656 Sqn AAC are now aboard the QE for SHOL trials over the coming 2 weeks out to mid July 19.
656 Sqn is the assigned UK AAC Apache unit for future ops from the QE carrier class.
For the SHOL trials personnel from 657 (D&T) Sqn AAC and QinetiQ Boscombe Down are also involved with the trials flying and planning and data gathering and analysis.

You may wonder why HIFR is necessary with such a large flight deck, as the technique was first used by the RN in the 70s to extend the range of Sea Kings when on patrol by refuelling from frigates at the edge of a task group whose fight decks were too small for such a large helicopter. The technique was used in the Falklands War supplemented by dropping off a relief crew on the frigate on the outbound leg of the sortie who would take over when the helo came back to refuel. The main value is that if the helo lands on the flight deck, it has to be shut down and secured before it can be refuelled, then checked over before it can be relaunched, which all takes time. This way the helo can be kept 'on task' with minimum disruption:65054406_2277130112603312_1325385375211847680_n.jpg 65029546_2277130149269975_8264185606343491584_n.jpg 65392492_2277130142603309_4477728496726048768_n.jpg 65386763_10156166846956481_2211653431519608832_n.jpg It also means minimum disruption when the flight deck is busy. The ASW screen )and AEW helos) can maintain round the clock protection for the fleet/

91 here, but this cool wet spring made a big wimp out of me?? I thought I was suffocating when I got out of the truck and on my tractor, but I felt so good I went and burnt a big brush pile!

yeah I'm no expert, but I would've thought the elevators speed hadn't been limiting combat ops!

I'm not in the MIC Conspiracy though I think ridiculously fast elevators which don't work is an example of creating over-engineered and overpriced 'solutions' to make the Pentagon pay even more;

the companies sure have teams of spin-doctors who come up with fancy 'products' like LCS mission modules concept, so called stealthy 16k-displacing Zumwalts and other game-changers, for example recently the USN asked for like 3b for unmanned 'fleet' without having ConOps! I don't believe it's Admirals creating this type of nonsense, I think it's marketing departments and their consultants in action, selling EDITED

The Navy’s new plan to fix Ford’s elevator failures

.

“We have a full court press on the advanced weapons elevators,” said

, the assistant secretary of the Navy for research, development and acquisition in a Monday press release.

With only two of Ford’s 11 elevators operating — and no firm schedule for delivering the remaining nine — the Navy brought a “team of experts” from both the government and private industry on board the Ford to fix the snafus, according to Geurts.

The sea service also announced Monday that officials will build a pair of testing facilities to help engineers fix problems and prep sailors to operate and maintain the elevator technology.

Navy spokesman Capt. Danny Hernandez told Navy Times on Monday that the ongoing bugs include “construction challenges” caused partly by “very tight tolerances, physical structural adjustments and software refinement” needed to make “weapons movement sustainable and reliable."

“Getting the doors and hatches installed was not enough. There has been learning on the sequence of building them,” Hernandez said.

He said that operations must be checked and rechecked to ensure they’re “working according to specs,” as when the elevators need to maintain “holding water tightness” as they move through the decks.

“Doors and hatches have to be moving in the right sequence and as you’d expect. They have to be aligned,” Hernandez said. “Mr. Geurts feels once we get the uppers and lowers working, it’s just a matter of improving efficiency.”

Guerts told

that Ford’s expected yearlong post-shakedown maintenance availability would be extended three months. That will delay the carrier’s return to sea until October.

Officials wanted all the

so the Navy could begin to fully test the $13 billion Ford’s flight deck capabilities.

On Monday, Geurts indicated that the team of experts, working with Huntington Ingalls Industries, will find “the most efficient timeline possible” for getting Ford’s elevators to work.

They will identify systemic problems and “recommend new design changes” for the installation of the elevators on board other Ford-class carriers, he added.

If the team can get the elevators to work in concert with Ford’s revolutionary arresting gear and electromagnetic catapults, officials hope to hike the number of aircraft sorties by 33 percent compared to the previous Nimitz class of warships.

Those elevators are expected to tote 24,000 pounds of ordnance at 150 feet-per-minute compared to a Nimitz carrier’s 10,500 pounds at 100 feet-per-minute.

Ford’s elevators rely on electromagnetic technology instead of cables and pulleys.

For testing and virtual technology training, officials want to replicate the Ford’s technology ashore at Naval Surface Warfare Center Division Philadelphia and a “digital twin” test site at the Newport News shipyard.

Increasingly concerned over technological problems plaguing its new $13 billion nuclear-powered aircraft carrier, the Navy has dispatched a unique team of civilian and government experts to the USS Gerald R. Ford in a new attempt to understand what is happening.

The experts, pulled from outside the defense industry in order to provide a fresh perspective, were selected for their expertise in working with complex electromagnetic systems, a technology that has proved daunting for the Navy and shipbuilder Huntington Ingalls at its Newport News Shipbuilding facilities in Virginia.

The team, which Navy officials have declined to identify, started work last month on getting the ship’s 11 electromagnetic weapons elevators up and running, a task that the Secretary of the Navy has

on, telling President Trump he can fire him if they’re not in working order.

Currently, only two of the ship’s new weapons elevators are operational, meaning sailors are unable to quickly move munitions from belowdecks to aircraft ready to take off.

“We have a full court press on the advanced weapons elevators,” said James Geurts, assistant secretary of the Navy for acquisition, in a statement. “We’ve gathered a team of experts on the carrier right now, which will work with the shipbuilder to get Ford’s weapons elevators completed in the most efficient timeline possible.” Significantly, Geurts said, the team “will also recommend new design changes that can improve elevator activities for the rest of the Ford class.” The group, the Navy said, has worked in electromagnetic systems, fabrication and production control, software, systems integration, and electrical engineering in the commercial sector.

The admission of serious design flaws with one of the carrier’s most vaunted new technologies is another acquisition and maintenance-related black eye for the Navy, which is

in the missile tubes aboard its next-generation Columbia-class nuclear submarines.

Navy officials point out that the electromagnetic elevators are a significant new technology that has proven reliable in early testing, and should be viewed as a leap-ahead effort that will come with some expected growing pains. The new elevators are designed to lift 20,000 pounds of munitions at a rate of 150 feet per minute, as opposed to the current Nimitz-class elevators which move 10,500 pounds at 100 feet per minute.

But perfecting that new technology has so far proven difficult.

Earlier this year, the Navy

the schedule for getting the Ford to sea for its next round of trials, moving the tests from July to October, due to a number of issues, including the elevators.

The schedule slip has put Navy Secretary Richard Spencer in an awkward position, as

President Trump, “I asked him to stick his hand out; he stuck his hand out. I said, let’s do this like corporate America. I shook his hand and said, the elevators will be ready to go when she pulls out or you can fire me.”

The issues with the Ford have also caught the attention of Sen. Jim Inhofe, chairman of the Senate Armed Services Committee,

that delays with the elevators present a “serious readiness gap” if they eventually delay the ship’s first deployment slated for 2021.

There is little chance the ship gets the elevators working by October, as the problems continue to vex engineers.

Overall, the eleven weapons elevators on the ship consist of four upper elevators and seven lower elevators, with the two working lifts among the upper elevators. The lower elevators are a more difficult problem, as they pass through several decks, have a number of hatches to move through, and must repeatedly hold water tightness as they move through a series of sequences to align with one another.

“The two upper stage elevators have absolutely operated as designed,” said Lt. Cmdr. Chabonnie Alexander, Ford’s Ordnance Handling Officer, in a statement. “We operate the elevators 10 times a day, five days a week” and the ship’s crew is becoming “better able to anticipate and diagnose any technical issues that may arise.”

The priority is to get two of the lower elevators running next, so whatever fixes are made can hopefully be repeated in the rest of the lower elevators as soon as possible.

One of the issues, however, is that the Navy installed the elevators without first refining their operation on a land-based prototype, meaning their installation on the first ship in the class has, in effect, acted as the prototype for the entire class of ships.

To get at some of those issues, the Navy is constructing a land-based test site at a naval facility in Philadelphia slated to be finished next year, and it is building what service officials are calling a “digital twin” — a detailed computer model constantly updated with data from the real-world systems — in Newport News that will be used for troubleshooting issues. “Both systems will allow the Navy and shipbuilder to mature the technology and aide in troubleshooting,” Navy spokesman Capt. Danny Hernandez said.

That extra work on the forthcoming ships in the class is critical, as the Navy

to start work on the third and fourth carriers of the class.

No its not just the Ford, but Richard Spencer should probably be looking for a new job. We'll see, he took responsibility for the elevator repair, but went further and offered his job as assurance that they would be fixed???
