President Trump Wants Gerald Ford Carriers to Use ‘Goddamned Steam’ Catapults Instead of ‘No Good’ Electromagnetic Launchers
11 May 2017 Sam LaGrone and Megan Eckstein

"...The following is the excerpt from the Time magazine interview on the subject of the Ford-class carriers.

On the future USS Ford-class carriers

You know the catapult is quite important. So I said what is this? Sir, this is our digital catapult system. He said well, we’re going to this because we wanted to keep up with modern [technology]. I said you don’t use steam anymore for catapult? No sir. I said, “Ah, how is it working?” “Sir, not good. Not good. Doesn’t have the power. You know the steam is just brutal. You see that sucker going and steam’s going all over the place, there’s planes thrown in the air.”

It sounded bad to me. Digital. They have digital. What is digital? And it’s very complicated, you have to be Albert Einstein to figure it out. And I said–and now they want to buy more aircraft carriers. I said what system are you going to be–”Sir, we’re staying with digital.” I said no you’re not. You going to goddamned steam, the digital costs hundreds of millions of dollars more money and it’s no good."


"EMALS is already installed on Gerald R. Ford (CVN-78), and in 2015 the Navy began buying materials for EMALS on the follow-on John F. Kennedy (CVN-79). In January, the service awarded a $527 million contract to General Atomics for EMALS on the third Ford-class carrier, Enterprise (CVN-80).

While early EMALS development was challenging for the service and slipped in cost and schedule, the Navy has been a vocal supporter of the launching system in the last several years....

...From the transcript published by Time, it’s unclear with whom Trump spoke about the EMALS system and when....

...With EMALS, though, the electromagnetic field creates a smoother acceleration and doesn’t subject the aircraft to steam. Along with the new AAG, which refines how it stops an airplane based on its weight, “what it also does is open up … the envelope for lower-weight aircraft. So as we start exploring where we’re heading with unmanned aircraft, it gives us a lot of flexibility from a warfighting standpoint that the (legacy system) doesn’t,” Moore said.

“You can now start to do things with aircraft design that you couldn’t do before. It might allow us some more margin in weight, in size, and in structure and capability,” Manazir added...."

MV-22 Ospreys Could Be Next to Get F-35’s Precision Landing System
21 Jun 2017 Hope Hodge Seck

"SALON DU BOURGET, Paris — The system that helps the F-35 Joint Strike Fighter achieve safe and precise landings in any weather could be coming next to the Marine Corps’ prized tiltrotor MV-22 Osprey.

The Raytheon-built Joint Precision Approach and Landing Systems, or JPALS, is a GPS-based system that triangulates between an aircraft and pieces of hardware on a ship or landing zone to create a cyber link as far as 200 nautical miles out.

The shipboard software can interact with the plane to assist in landings and navigate through challenges that might render other aircraft unable to operate, such as severe weather or an environment in which communications are jammed.

JPALS capability is embedded in all three F-35 variants as part of the Joint Strike Fighter’s 3F software block, although the Air Force has not opted to pursue the capability for its F-35A conventional landing variant.

By 2018, the Navy plans to install JPALS hardware on two amphibious assault ships, the Essex and the Wasp, just in time for the ships to depart on ocean deployments with a contingent of F-35s aboard for the first time.

Meanwhile, Raytheon is eyeing its next potential customer.

“The Osprey, it’s in their requirements that they want to make that happen,” Bob Delorge, Raytheon’s vice president for Transportation and Support services, told Military.com in an interview here at the Paris Air Show on Tuesday. “It makes a lot of sense in terms of the Marines. We’re looking at where do you go now from an expeditionary point of view, how do you get that on board.”...

...To accommodate JPALS for Ospreys, which take off and land on amphibious ships, Delorge said Raytheon is working to shrink down the hardware the system requires. Today, that’s about four cabinets’ worth of computer equipment, plus dinner plate-sized GPS devices. “You can probably shrink down to something smaller, try to get expeditionary with the Marines,” he said.

If the Marine Corps or the Navy pursues JPALS for Ospreys, fielding would still likely be years out, Delorge said. But the Osprey isn’t the only aircraft Raytheon has in its sights for JPALS. The company is also hoping to attract international buyers.

“The conversations that we have had with the Navy is, how do we now start thinking about international,” Delorge said. “When you talk to the captain, a big part of what he’s thinking through is interoperability. There are very few missions where the U.S. is operating by itself. As you put out F-35s, you want to ensure you have that interoperability.”"

.....with JPALS the Corp will be able to bring the vertical landing fleet (H-1 to H-53) to any ship (LHA to LCS) from 200 miles out to a 1 ft. by 1 ft. landing accuracy in all weather. A mobile JPALS could bring a F-35B in to a temporary FOB ( "a bush near you" ) for rearming/ refueling in any weather by dropping off a Humvee (H-53/ MV-22) with the mobile JPALS mounted on the rear deck. ...thus bringing expeditionary to Marine aviation where it is needed.

,,,,I've heard recently the Brits are considering JPALS for the new QE... :wink:

ON page four of this thread there is a bunch o'stuff about OUIJA Boards so I'll stuff it here. Search on OUIJA for more scary bits o'info. viewtopic.php?f=22&t=14115&p=233955&hilit=OUIJA#p233955
Old School Meets New School: Flight Deck Ouija Boards Go Digital
15 Jun 2017 Warren Duffie ONR

"ARLINGTON, Va.—The flight decks of aviation-capable vessels like aircraft carriers bustle with noise and danger—screaming jets, snapping steel cables and powerful tractors and forklifts. Planning and orchestrating this high-octane dance requires precision and accuracy from those responsible for directing deck traffic.

To make the jobs of aircraft handlers easier, the Office of Naval Research’s (ONR) TechSolutions program has sponsored the development of the Deployable Ship Integration Multitouch System—DSIMS, for short.

DSIMS is a mobile software package that features a digital, touchscreen image of a ship’s flight deck or hangar bay, and can be used on a laptop or desktop computer. It enables aircraft handlers to change flight deck configurations anywhere on the ship, plan operations before deployment, and share information digitally with other DSIMS users for improved collaboration.

“This interactive, computerized system is a leap forward for naval aviation,” said ONR Command Master Chief Matt Matteson. “It’s a fairly straightforward technological solution that brings with it tremendous functionality and saves time.”

To track the movements of aircraft and equipment on the flight deck, handlers currently use a tool informally called a “Ouija board”—a waist-high, six-feet-long physical replica of the deck. Located in the ship’s flight deck control center, the board is covered with toy-like plastic models of aircraft, each marked with colored thumbtacks to designate maintenance, fuel or flight status.

The Ouija board’s design has barely changed since World War II. Despite its effectiveness, however, it does have limitations. For example, if aircraft handlers need to plan for upcoming or unexpected scenarios—bad weather or a surprise VIP visit—they must do so while underway, and change the Ouija board back to its original layout after completing the planning session.

By contrast, DSIMS can help plan such situations months before a ship leaves port. When playing out various flight deck situations—called “evolutions”—on the DSIMS touchscreen, participants can use their fingertips or a computer mouse to move around digital aircraft, to show which aircraft need to be in which location and where crates and other equipment should be positioned.

There also are special screen modules denoting aircraft fueling needs, maintenance requests and availability for flight. Each evolution can be saved and recalled during operations, or used for briefings and training.

“DSIMS allows for planning of future evolutions,” said Tim Zieser, an engineer at Naval Air Warfare Center Aircraft Division, Lakehurst, New Jersey. “It also enables aircraft handling officers to create briefs that can be used to inform the chain of command, and train their people before a complex evolution, so everyone is on the same page.”

Zieser recently demonstrated DSIMS at Lakehurst’s Carrier Analysis Lab for Sailors and Marines from the USS Iwo Jima (LHD-7), before the amphibious assault ship deployed.

“The technology is fantastic,” said Lt. Timothy Sullivan, stationed aboard the Iwo Jima. “It lets us make time-critical decisions today, so we don’t have to months from now, over the Ouija board on the ship. It will save us man hours down the road as we execute the mission.”

DSIMS originated in 2016, when a request from Commander, Naval Air Forces, was sent to ONR’s TechSolutions program for a digital, mobile version of the Ouija board. TechSolutions is ONR’s rapid-response science and technology program that develops prototype technologies to address problems voiced by Sailors and Marines, usually within 12-18 months.

Later this year, TechSolutions will deliver a prototype DSIMS for testing and evaluation on several ships, including the Iwo Jima. Zieser and his team hope to see the system issued throughout the fleet next year."

This article seems like OLD NEWS to me but hey - whatever....
USN reveals source of EMALS mechanical issues
25 Jun 2017 Anika Torruella

"The General Atomics-built Electromagnetic Aircraft Launch System (EMALS) installed on the first-of-class nuclear-powered aircraft carrier USS Gerald R Ford (CVN 78) is being "fine-tuned" to overcome a vibrational issue associated with optimising the launch and recovery of different aircraft appropriate for their configuration, Acting Secretary of the US Navy (USN) Sean Stackley stated at a congressional hearing on 16 June 2017.

"What we're going through right now is developing the bulletin for launch and recovery of the various type, model, series aircraft in the fleet that will be operating off of the carrier," Stackley said.

EMALS is intended to enable a higher degree of computer control, more accurate end-speed control, and smoother acceleration when launching carrier-based fixed-wing aircraft, such as F/A-18E/F Hornets and Super Hornets, EA-18G Growlers, and C-2A Greyhounds. It is also intended to be able to adapt to future carrier air-wing platforms, such as lightweight unmanned systems or future heavy strike aircraft.

US lawmakers noted that the issue with the new catapult system had been previously described as a problem with "its ability to launch aircraft – particularly aircraft that have all their fuel tanks in place".

"We started [at the test site in Lakehurst, New Jersey], where we have the land-based system, and they basically start slow and build up in terms of launching and recovering the aircraft," Stackley said. "In that process, with F-18s with fuel tanks attached, vibration was detected. And so now what they're doing is going back through the software and adjusting the system to remove that vibration."

"Today they're renewing that testing at Lakehurst in advance of when we'll first do launch and recovery operations on the Ford, later [in mid- to late-2017]," Stackley said...."

Navy validates software fix for EMALS
25 Jul 2017 Lee Hudson

"The Navy recently validated a software fix for the Electromagnetic Aircraft Launch System, despite negative comments about the program from President Trump. Following a review in April 2014 of aircraft instrumentation data, a problem was discovered after testing. The testers found holdback release dynamics exceeded current fleet allowances during launches of these aircraft configured with wing-mounted external fuel tanks.

"We were confident since the day that the issue was uncovered that it was solvable," EMALS integrated program team lead George Sulich said in a July 24 statement. The final step of testing the fix with instrumented aircraft launches was delayed a year because of competing test priorities, according to a service statement.

"The subsequent software will be incorporated on board CVN-78 to support shipboard launches of F/A-18s with EFTs in 2019, following the ship's Post Shakedown Availability," the statement reads...."

Navy’s new launch system eliminates concerns with latest testing
24 Jul 2017 PEO(T) Public Affairs

"NAVAL AIR SYSTEMS COMMAND, PATUXENT RIVER, Md. – The Electromagnetic Aircraft Launch System (EMALS) team completed testing at Joint Base McGuire-Dix-Lakehurst, New Jersey, early this summer, validating a software fix that will ensure safe launches.

A total of 71 EMALS launches were conducted by the EMALS Team and the Air Test and Evaluation Squadron (VX) 23 to confirm F/A-18E/F Super Hornet and EA-18G Growler outfitted with wing-mounted, 480-gallon external fuel tanks (EFTs) can launch without exceeding stress limits on the aircraft.

The post-test review of aircraft instrumentation data, following the manned aircraft testing, indicates that software control algorithm updates have corrected the issue....

...“We were confident since the day that the issue was uncovered that it was solvable,” said George Sulich, EMALS integrated program team lead. “The beauty of the system is that issues such as these can be accomplished with software updates instead of major hardware changes to machinery.”

He explained that the EMALS team promptly planned a resolution for further tuning of the system’s control algorithm, which would reduce the loads on the EFTs to within established operational limits. All design, development, software coding, laboratory testing and dead-load testing, using weighted, aircraft-representative sleds, was completed in 2015.

Since several other software updates had occurred since the fix was originally established, in April of this year, the team loaded the software build intended to correct the deficiency and conducted an additional 152 dead-load launches at the System Functional Demonstration Site to support flight test readiness.

The final step of testing the fix with instrumented aircraft launches was delayed a year due to competing test priorities, but is now complete. The subsequent software will be incorporated on board CVN 78 to support shipboard launches of F/A-18s with EFTs in 2019, following the ship’s Post Shakedown Availability...."
