The US Navy is set to christen the tenth San Antonio-class amphibious transport dock ship on 21 March at the Huntington Ingalls Industries' (HII) shipbuilding division visitor control centre.


The ship is being named in honour of late John P Murtha, who represented Pennsylvania's twelfth congressional district from 1974 to 2010.


Having served in the Marine Corps for 37 years, Murtha saw service in the Korean War and in Vietnam, and earned the Bronze Star with Valor device, two Purple Hearts and the Vietnamese Cross of Gallantry.


Launched on 30 October 2014, the LPD 26 is scheduled for delivery to the navy in 2016 and will join the first nine ships of the San Antonio-class.


USS Portland (LPD 27), the final ship of the current San Antonio-class, was keel laid in August 2013 and is currently under construction at HII.


Designed to serve as a key element of the navy's sea base transformation, the LPDs are being developed to enable deployment of the combat and support elements of marine expeditionary units and brigades.


Featuring a flight deck and hangar which can operate CH-46 Sea Knight helicopters and the Osprey tilt-rotor aircraft (MV-22), the LPD 26 will be equipped with a well deck capable of embarking and debarking landing crafts, air cushion, the Expeditionary Fighting Vehicle (EFV), to deliver marines ashore.


The 684ft-long San Antonio-class ships have a displacement capacity of 25,000t and more than 23,000ft2 of vehicle storage, capable of transporting a landing force of up to 800 marines and their equipment.


The 11 ships will functionally replace more than 41 ships across four classes, providing the navy and marine corps with modern, sea-based platforms.

Navy's Brand New Aircraft Launch System Embarks on Below-Deck Testing


Aug 12, 2014 ASDNews Source : Naval Air Systems Command


The Huntington Ingalls Industries (HII) shipyard in Newport News, Virginia is all abuzz as below deck-testing of the Navy’s newest aircraft launch system begins aboard USS Gerald R. Ford (CVN 78).


Following months of large-scale hardware deliveries containing critical components of the Electromagnetic Aircraft Launch System (EMALS) and shipboard installation by HII, teams from the government and industry partner General Atomics completed installation of the software — the brains of the new system. Below deck-testing began Aug. 11 with the Launch Control Subsystem, the first of many subsystem assessments on the path toward EMALS shipboard certification.

USS Abraham Lincoln receives final mast section

The US Navy's fifth Nimitz-class nuclear-powered aircraft carrier USS Abraham Lincoln (CVN 72) has received the 38ft upper mast section as part of its refuelling and complex overhaul (RCOH), at Huntington Ingalls Industries' Newport News Shipbuilding.


The installation marks a major milestone in the ship's RCOH programme.


Newport News Navy programmes vice-president Ken Mahler: "Since we began the refuelling complex overhaul, we've been working side-by-side on this project to recapitalise and modernise the entire ship, such that when she returns to service, Lincoln will continue to be one of the most capable and formidable ships in the world."


During the RCOH process, the company replaced the original round mast pole with a modified, tapered square pole, to increase strength and keep electrical piping systems enclosed.


The square pole includes waist-high rails and easier access to all areas via internal ladders.


The RCOH process, which is performed as part of the navy's $2.6bn cost-plus-incentive-fee contract awarded in April 2013, also includes the refuelling of the ship's reactors, painting of the hull, an upgraded system and a complete recapitalisation.


Armed with three Raytheon GMLS Mk29 eight-cell launchers for Nato Sea Sparrow surface-to-air missiles, the 317m-long Nimitz-class ships can accommodate more than 6,000 personnel and cruise at a maximum speed of over 30k.


Upon the scheduled redelivery in October 2016, the 102,000t USS Abraham Lincoln will continue to operate for another 25 years.

Huntington Ingalls Industries (HII) has begun fabrication of the US Navy's Aegis-equipped Arleigh Burke-class guided missile destroyer, USS Ralph Johnson (DDG 114), at its shipyard in Pascagoula, Mississippi, US.


More than 100t of steel has been cut for the fabrication of the vessel.


USS Ralph Johnson, which was named after Marine Pfc. Ralph Henry Johnson, who received the medal of honour for his heroic actions during the Vietnam War.


HII's DDG 51 programme manager, George Nungesser, said: "We have talented, experienced shipbuilders working on this programme, and they have provided excellent quality on Aegis destroyers since the programme's inception."


In September 2011, the US Navy had awarded a contract to HII for the construction of DDG 114, as a flight IIA Arleigh Burke-class (DDG 51) destroyer.


Powered by four gas-turbine propulsion engines, the Arleigh Burke-class ship will feature a SPY-1D multi-function phased array radar to support a variety of operations.


The 509ft-long Arleigh Burke-class vessels have a displacement capacity of 9,500t. They can cruise at a speed of 30k and are equipped with advanced sensors, as well as weapons systems to engage anti-ship missile threats.


Scheduled to be delivered to the navy in the first half of 2017, the USS Ralph Johnson multi-mission ship can support missions ranging from peacetime presence and crisis management to sea control and power projection, all in support of the US military strategy.


USS John Finn (DDG 113), the first of the DDG 51-class programme continuation ships, is scheduled for delivery to the US Navy in the third quarter of 2016.


The third and fourth ships of the Flight IIA programme, USS Rafael Peralta (DDG 115) and USS Thomas Hudner (DDG 116) respectively are currently undergoing construction.

Huntington Ingalls Industries and General Dynamics Bath Iron Works will build nine DDG 51 Arleigh Burke-class destroyers for the U.S. Navy.


The two separate, multiyear procurement contracts are together worth more than $5.1 billion.


The Navy said General Dynamics Bath Iron Works will design and build four DDG 51 class ships beginning this year and continuing into 2017. The contract includes an option for a fifth ship.


Huntington Ingalls Industries will construct five ships, one each year until 2017.


"These contract awards represent great value to the taxpayer and will ensure our warfighters have the ships and systems they need to prevail in any situation," said Secretary of the Navy Ray Mabus. "By leveraging competition in the DDG 51 class shipbuilding program, these shipbuilders will continue their proud histories in delivering these highly capable ships to the fleet while meeting critical operational requirements for integrated air and missile defense capability."


The Navy said the destroyers will be in a Flight III configuration in which Aegis AN/SPY-1D radar is replaced with Air and Missile Defense Radar, and improved weapons and sensor suites are installed.
