Pentagon Directs Shock Tests on Carrier Ford

Experts say Ford delay to cause more deployment flux
New tests for the first-in-class supercarrier are likely to delay the ship's arrival in the fleet, and experts say the delays will lead to less presence overseas or the last-minute ship schedule changes that officials have been trying to avoid.

Pentagon leaders have ordered the Navy to run the carrier Gerald R. Ford through shock tests, where explosives are set off close to the ship to test the soundness of the design. The tests, Navy leaders say, will push the Ford's first deployment back by half a year at least, according to a report in Navy Times' sister publication Defense News.

That forces the fleet to operate with 10 flattops even longer, a setup where the slightest setback will force officials to take up unpopular moves like extended deployments or temporarily lower carrier force levels overseas.

It's just the latest hitch in the implementation of the new deployment scheme that promises sailors more predictable schedules but has suffered repeated setbacks.

Chief Of Naval Operations Adm. Jon Greenert has stated that the Navy is seeking to return to 7-month deployments, calling repeated eight, nine and 10-month deployments unsustainable.

But with 10 carriers, and a standing requirement to have a carrier in the Pacific and one in the Middle East, the Navy has no more room for error, said Bryan Clark, a retired commander and analyst at the Center for Strategic and Budgetary Assessments.

"You can just barely provide 2.0 [carrier] presence in PACOM and CENTCOM, and that's with the [forward deployed] carrier in Japan," Clark said. "You can't account for any additional presence, like a three-week excercise somewhere, there is no time for that. And if somebody breaks or there are maintenance delays in the yards, there is no time for that either."

"You are basically in a heel-to-toe deployment cycle from now to the time that Ford enters the fleet," Clark added.

A day after news of the shock testing emerged, Navy spokesman Lt. Tim Hawkins was unable to elaborate on the delay's ramifications for the fleet but said the service is committed to predictable deployments.

"We were aware of the implications when the decision was made and we're prepared to manage our way through this," Hawkins said. "It is too early to speculate on future force-wide impacts, but we remain committed to implementing the Optimized Fleet Response Plan and scheduling regular deployments that are seven months in length."

Bryan McGrath, a retired destroyer skipper and head of the Ferrybridge Group, agreed, saying that as long as there were 10 carriers, the Navy's options for fulfilling the standing requirements are narrow.

McGrath pointed to the looming carrier shortage in the Middle East — and amid the campaign against the Islamic State militants — as a symptom of the delays in getting the Ford to the front. Navy Times reported in June that the Navy planned to pull its carrier from Central Command in the fall.

"The carrier gap is a fact of life with a 10-carrier Navy, which we essentially are until Ford joins the fleet," he said. "So the longer it takes for the Ford to take its place in the fleet, the more likely we will be to have either gaps in presence and/or extended deployments."

The Navy has to fill the two standing requirements, McGrath explained. The carrier math is straightforward, he continued: at any given time, two carriers are deployed, two carriers are either returning or have just returned, two are just about to deploy, two are in workups, two are in regular maintenance periods and one is in a four-year complex overhaul and refueling.

The Ford was scheduled to be delivered in March 2016, and was tentatively slated for a 2019 deployment. Balancing the deployment requirements in a 10-flattop fleet will be a continuing struggle for Fleet Forces Command, led by Adm. Phil Davidson, and incoming Chief of Naval Operations Adm. John Richardson.

A very crude estimate based on 125Kts, a 200 foot long ramp, and a 30 degree exit angle gives me around 3-4 G's. This assumes an even G loaded curve profile to the ramp. Not too bad I guess. Are landing gears usually designed to a base load strong enough to take that?
That exit angle is not 30 degrees but about 12. That makes a lot of difference. That is still no reason to have a ski ramp at the end of the angle deck. You have to consider what is the advantage of accepting a higher landing weight and after a bolter leaving the deck at a lower speed, which wont happen often, against the damage if an aircraft misses the ramp after a bolter and the loss of spotting place in that area.

History of the Navy UCLASS Program Requirements: In Brief
(dated August 3, 2015)
Summary
During its development, the U.S. Navy’s Unmanned Carrier Launched Airborne Surveillance and Strike (UCLASS) aircraft and its predecessors have been proposed to fill a number of roles and operate in a variety of air defense environments. Over time, those requirements have evolved to encompass a less demanding set of capabilities than first envisioned. This report details the history of UCLASS requirements development through the program’s evolution to its current stage.

HII-to-Hold-Keel-Laying-for-John-F_-Kennedy.jpg

Naval Today said:
Huntington Ingalls Industries announced that it will host a keel-laying ceremony for the aircraft carrier John F. Kennedy (CVN 79).

The event will be held at the Company’s Newport News Shipbuilding division alongside Dry Dock 12 on Saturday, August 22.

The ship’s sponsor and daughter of the ship’s namesake, Caroline Kennedy, will participate via video.

Gerald R. Ford (CVN 78) is the first new design for an aircraft carrier since Nimitz (CVN 68). The ship will be equipped with two newly-designed reactors and has 250 percent more electrical capacity than previous carriers. The improvements will allow the ship to load weapons and launch aircraft faster than ever before.

Naval Today said:
In preparation for delivery later this year, NUSHIP Adelaide will start her final period of sea trials today.

The second of the Landing Helicopter Dock (LHD) ships being built for the Royal Australian Navy (RAN) will leave the BAE Systems’ Williamstown shipyard and head up the eastern coast of NSW to the Jervis Bay area.

About 200 BAE Systems employees, equipment/system subcontractors, RAN crew members and representatives from the Department of Defence Capability Acquisition and Sustainment Group will be on board to support the trials which are expected to last 10 days.

Pivotal to this period of sea trials will be testing of the ship’s combat and communications systems in a range of scenarios to validate the systems’ capabilities. Like her sister ship HMAS Canberra that was delivered by BAE Systems last October, HMAS Adelaide is the largest and most complex type of vessel that the RAN operates.

When she returns from sea trials, NUSHIP Adelaide will be prepared for delivery. The RAN will have the opportunity to perform various routine alongside exercises as it continues to build its capability for crewing the vessel while the ship compartments and systems are progressively handed over to the NUSHIP Adelaide crew.

The crew has already been trained for its role on the RAN’s second Landing Helicopter Dock ship.

Here are both of Australia's new LHDs, Canberra (L02), and Adelaide (L01), recently docked together before Adelaide began her latest sea trials. Very nice looking vessels.

Three US nuclear aircraft carriers in San Diego:

US Navy said:
SAN DIEGO (Aug. 15, 2015) The aircraft carriers USS George Washington (CVN 73), USS Ronald Reagan (CVN 76), and USS Carl Vinson (CVN 70) sit across from the USS Midway Museum in San Diego Bay.

Just think, the US Navy could have those three babies sitting there in San Diego...and have three more just like them sitting in two other places in the world, and then have another left over for change.

EMALS dead weight sled test completed successfully and she is looking good folks! She is preparing to be delivered to the US Navy (not commissioned, just delivered for naval trials) in March 2016...folks, that's only seven months away.

Can't wait to see her plowing the waves. As it is, right now she is looking good.
