The U.S. Navy’s newest and most high-tech destroyer is stuck in Panama after suffering an engineering casualty during a transit of the Panama Canal and just one month after the US Navy’s newest Littoral Combat Ship suffered damage in the canal during a return visit to shipyard after multiple engine failures.

Citar
The US Navy (USN) has grounded its fleet of Boeing F/A-18E/F Super Hornet and EA-18G Growler combat aircraft while it investigates the cause of a ground incident on 16 December that injured two flight-crew.

The incident at Naval Air Station (NAS) Whidbey Island in Washington state saw an EA-18G Growler from Electronic Attack Squadron (VAQ) 132 experience an unspecified "on-deck emergency" that required both crew members to be airlifted to hospital, a USN statement said.

As a consequence of the incident, the USN has ordered a temporary suspension of all Super Hornet and Growler flight operations while the Naval Air Systems Command and Boeing conduct their investigation. Exceptions to this grounding order will be made on a case-by-case basis.

Key Points
System testing on USS Gerald R Ford is more than 75% complete, says shipbuilder
Less than 10% of overall test programme remains to be finished
Systems testing aboard the US Navy's (USN's) new nuclear-powered aircraft carrier, lead ship the future USS Gerald R Ford , is more than three-quarters complete, according to Michael Petters, CEO of shipbuilder Huntington Ingalls Industries (HII).

"CVN 78 Ford is essentially complete, with less than 10% of the overall test programme remaining to be completed," Petters told a recent briefing on the company's earnings. "We are prosecuting the repairs on the main turbine generators and moving towards sea trials."

Resolving issues relating to the turbine generators has been a challenge as the company has worked towards delivering the ship. The navy had planned to take delivery of the ship in 2016; at this stage, no delivery date has been confirmed, although IHS Jane's understands that the navy may provide an update on progress towards this aim by the end of the year.

Two of the key systems currently undergoing additional testing are the Electromagnetic Aircraft Launch System (EMALS) and the Advanced Arresting Gear (AAG). These systems are central to the launch and recovery, respectively, of embarked aircraft.

Of the two, EMALS development, installation, and integration have kept mostly to schedule and expectation. The system has undergone nearly all testing planned before delivery, according to Michael Land, a spokesperson for Naval Air Systems Command, in response to questions from IHS Jane's . Once that testing is complete and the carrier is delivered, HII's team will turn the system over to Ford 's crew to test EMALS with aircraft onboard the ship.

AAG testing appears to be back on track following some setbacks, according to the USN. The navy is still testing the system, following a re-design of its water-twister components.

Citar
The US Navy (USN) has declared initial operating capability (IOC) for its AN/AES-1 Airborne Laser Mine Detection System (ALMDS), manufacturer Northrop Grumman announced on 12 January.

The milestone for the ALMDS comes under two-and-a-half years after operations with the helicopter-based system began in August 2014.

Fitted to a Sikorsky MH-60S Knight Hawk helicopter, the ALMDS is an airborne mine countermeasures (MCM) Light Detection and Ranging (LiDAR) sensor that is designed to provide rapid wide-area reconnaissance and assessment of mine threats in sea lanes, littoral zones, confined straits, choke points, and amphibious areas of operations.

According to Northrop Grumman, the ALMDS differs from previous airborne counter-mine systems in that the laser affords faster sweep and detection speeds to significantly improve the navy's mine detection capabilities, and the self-contained pod that houses the sensor can be rapidly fitted and removed from the host aircraft. The 36,505 kg sensor pod is mounted externally on the helicopter on a BRU-14 weapon station mount. It is 2.7 m in length, has a diameter of 53 cm, and has no moving parts.

The operator on board the helicopter is presented with a 3D image of the upper volume of the sea that indicates the position of objects detected in this observed volume. He or she views a computer-enhanced image of detected objects, and displays their characteristics for comparison and correlation of mine-like objects and mines.

The Navy awarded Newport News Shipbuilding $25.5 million to begin advance fabrication of aircraft carrier Enterprise (CVN-80).

After beginning advance construction planning activities last spring, initial structure fabrication and shop work on the third Ford-class carrier should last through March 2018, the company announced in a statement.

“This award authorizes us to begin fabrication of structural components, sub-components, sub-units and pre-assemblies in our manufacturing shops to support the 2018 construction of Enterprise,” Mike Shawcross, Newport News’ vice president of CVN-79 and CVN-80 construction, said in the statement.
“This is an important step in getting this next Ford-class ship off to a great start, as it allows us to continue implementation of lessons learned, and the initial steel work will allow us to utilize our aircraft carrier steel production line in an efficient manner.”

The Navy awarded Newport News Shipbuilding a $152-miliion contract in May 2016 to begin advance planning activities, and this week’s money was added as a contract modification. Construction on Enterprise should begin in 2018, and the ship is expected to deliver to the Navy in 2027. Enterprise will replace the USS Dwight D. Eisenhower (CVN-69) upon entering the fleet.

In its statement this week, Newport News Shipbuilding stated that “shipbuilders have captured thousands of lessons learned and developed new build approaches during construction of Gerald R. Ford (CVN 78), most of which are being implemented as cost-saving initiatives in building the second ship in the class, John F. Kennedy (CVN-79). These initiatives will also apply to Enterprise, and (parent company Huntington Ingalls Industries) will work with the Navy to identify additional cost-saving initiatives for future Ford-class carrier construction.”

In an early example of implementing lessons learned, the shipyard moved a 704-metric ton unit into John F. Kennedy’s dry dock as part of a unique “superlift” event.

“The superlift is part of an improved build strategy implemented on the second ship of the Gerald R. Ford (CVN-78) class, resulting in superlifts erected at a higher state of outfitting completion,” the company said in a Jan. 23 news release.
“Kennedy is being built using modular construction, a process where smaller sections of the ship are welded together to form large structural units, equipment is installed, and the large units are lifted into the dry dock using the shipyard’s 1,050-metric ton gantry crane.”

CVN-79 is about 25 percent complete and set for deliver in 2022, when it will replace USS Nimitz (CVN-68). The ship is on tract to be completed with 445 lifts, which is 51 fewer than Ford and 149 fewer than USS George H.W. Bush (CVN-77), the last Nimitz-class carrier, according to a company statement.
