The U.S. Marines Are Pulling Old F/A-18s Out of Desert Storage
F-35 delays mean desperate measures
by DAVID AXE

The U.S. Marine Corps has received the first two old F/A-18 Hornet fighters that Boeing is pulling out the U.S. military’s retired-warplane storage facility in Arizona and refurbishing for continued service.
Under a contract the U.S. Navy signed with Boeing in 2014, the Chicago plane-maker is “reconstituting” 30 first-generation F/A-18s that have been sitting for years in open desert storage at Davis-Monthan Air Force Base near Tucson.

The US Navy’s newest supercarrier, the USS Gerald R. Ford, may struggle to launch and recover aircraft, mount a defence and move munitions.

It has been reported that on-board systems for the previously mentioned tasks have poor or unknown reliability issues, according to a June the 28th memo obtained by Bloomberg News.

Michael Gilmore, the Defense Department’s director of operational test and evaluation, wrote:

“These four systems affect major areas of flight operations. Unless these issues are resolved, which would likely require redesigning, they will significantly limit the CVN-78’s ability to conduct combat operations.

Based on current reliability estimates, the CVN-78 is unlikely to conduct high-intensity flight operations at the outset of a war.”

In January 2014, the annual Director, Operational Test and Evaluation (DOT&E) report said that critical ship systems including the EMALS, Advanced Arresting Gear, Dual Band Radar, and weapons elevators were not reliable enough and needed more testing and improvements.

EMALS testing recorded 201 launch failures out of 1,967 launches, equaling a reliability rate of 240 mean cycles (launching of one aircraft) between critical failures. Testing of the Advanced Arresting Gear recorded 9 arresting failures out of 71 attempts, equaling a reliability rate of 20 mean cycles (recovery of one aircraft) between operational mission failure, a failure rate 248 times higher than should be expected.

Those systems performed at a fraction of their requirements for shipboard configurations, and even less of required standards. Radar and weapons elevator test data was not made available, but were also below expectations.

The US Navy maintains that further testing will resolve the problems.

Finalmente uma explicação lógica a explicar todo o programa LCS da Marinha Norte-Americana e porquê é que eles agora vão transformar esses navios em autênticas fragatas.

After the end of the cold war, the USN had a bit of soul-searching to do. The only navy in the world owned by a hostile power that could conceivably challenge the U.S had disappeared, it's former ships rusting ignominiously in dock. Besides the Soviet Union, no other power had anything even remotely close to the USN - remember that, in 1991, the Chinese (PRC) navy was still limited to a handful of hopelessly obsolescent destroyers and frigates. There seemed to be little need for a navy designed for conventional engagements. Frigates like the Perry class, being a vessel meant for high seas escort missions, were of very low priority when it seemed that there was no one left to challenge the USN out in the ocean.

Post Cold-War, the focus shifted to littoral waters - close to the shore - which was the only place where hostile powers such as Iran or North Korea could hope to inflict damage on the USN, through the use of Fast Attack Craft, midget submarines, or motorboats (a la Iran-Iraq War). Thus was borne the Littoral Combat Ship - a vessel that was explicitly designed for these types of environments. Many of the class' characteristics are specifically designed for fighting so-called 'asymmetric threats'; high speed (~45 kt) is pointless in missile combat, but useful for chasing down smaller boats. The (now-cancelled) NLOS missile, to be carried in the anti-surface role, was too small to pose a major threat to a frigate or destroyer, but it's promised (and ultimately unachievable) loiter mode would have made it effective in eliminating small craft. Finally, the substantial internal cargo space and helicopter facilities makes it possible to use the ships in an ad-hoc amphibious role, for commando raids.

Unfortunately for the USN, the future didn't quite turn out the way that the planners had expected. Russia began to rebuild and refurbish it's navy - not to Soviet standards, but enough to pose a credible conventional threat. Much more worryingly, China is rapidly phasing out it's obsolescent cold-war era ships, and replacing them with domestic designs that are increasingly coming closer to matching Western designs; the PLAN has thirteen Type 052D Destroyers in service or under construction, each resembling a Flight I / II Arleigh Burke. The conventional threat is rapidly moving back into the picture, and the LCS, as originally designed, was a very poor match for it.

As such, there's been a re-evaluation of naval strategy of late, and, lo and behold, the frigate is back:

SNA: Modified Littoral Combat Ships to be Designated Frigates

The remaining LCS' are to be build to a modified specification. Gone are the modular mission packages and littoral seas focus. Instead, the ships will get better radar, CIWS and anti-ship missile launchers. The new ships will get the FF hull designation.

Precision Aircraft Landing System (PALS) Tested on Ford-class Aircraft Carrier at HII Shipyard
 
Huntington Ingalls Industries announced that its Newport News Shipbuilding division has successfully tested the Precision Aircraft Landing System (PALS) on the aircraft carrier Gerald R. Ford (CVN 78). PALS is a radar system that provides final approach and landing guidance to aircraft to ensure successful landings on the flight deck.

A special instrumented F-18 Super Hornet flew within about 500 feet of Gerald R. Ford 10 times during the testing, which verifies the proper functionality, alignment and operation of the PALS equipment and its subsystems. While the PALS technology is used on Nimitz-class carriers, Gerald R. Ford’s system is upgraded and modified for the new class’ island location and other design and technology changes. The dual band radar, also new to the Ford class, supported testing of the PALS.

“Aircraft landing precision is at the core of an aircraft carrier’s mission,” said Rolf Bartschi, Newport News’ vice president, CVN 78 carrier construction. “This test program ensures that the systems are working together as they were designed to work before we take the ship to sea.”

Gerald R. Ford represents the next-generation class of aircraft carriers. The first-in-class ship features a new nuclear power plant, a redesigned island, electromagnetic catapults, improved weapons movement, an enhanced flight deck capable of increased aircraft sortie rates, and growth margin for future technologies and reduced manning. Ford has been under construction since November 2009 and was launched in 2013.

USS Fort Worth departs Singapore following repairs to propulsion damage

USS Fort Worth has begun its journey towards San Diego after repairs to its propulsion systems
Vessel's damage was not as extensive as initially suggested, said the US Navy
The US Navy's (USN's) Littoral Combat Ship (LCS) USS Fort Worth (LCS 3) has left Singapore's Changi Naval Base for San Diego after a deployment that was inadvertently extended by almost half a year due to issues with the platform's propulsion systems.

Fort Worth arrived in Singapore in November 2014 for a rotational deployment that was originally scheduled to last for 16 months, but the platform sustained damage to its propulsion systems in January 2016.

The US Pacific Fleet said at the time that initial indications suggest that the damage occurred because proper procedures were not adhered to during a test of the vessel's engines. A commanding officer who was responsible for the platform during the incident has been relieved of duty.

"Damage to the ship's combining gears was less extensive than initial investigations suggested," said the USN in a statement on the vessel's departure on 22 August. "A full assessment revealed that only three bearings needed to be replaced, and the repairs took less time and cost less than originally expected," the service added.

Fort Worth 's departure was cleared after it passed a number of assessments and validations to confirm that the platform has resumed a fully operational status following its repairs, said the USN. The ship will make the journey to San Diego with the use of both main propulsion diesel engines.

USS Coronado (LCS 4) is currently scheduled to replace Fort Worth as the rotationally deployed LCS in Singapore and the vessel is making preparations to transit over from Hawaii, the service has confirmed with IHS Jane's .
