Acceptance Trials

Huntington Ingalls Industries (HII) announced on April 19 the successful completion of acceptance sea trials for the company’s 10th San Antonio-class amphibious transport dock, USS John P. Murtha (LPD-26). The ship, built at HII’s Ingalls Shipbuilding division, spent six days with the test and trials team performing more than 200 trial events that included both an in-port and underway portion.

«This was a significant test at sea for LPD-26, and the ship performed well», said Kari Wilkinson, Ingalls’ USS John P. Murtha (LPD-26) program manager. «The logistical performance it takes for our test and trials team to execute all of these events while underway is nothing short of phenomenal. Once again the Navy will be receiving a quality Ingalls-built ship that will be mission-ready and able to achieve whatever tasks the sailors and Marines require».

The U.S. Navy’s Board of Inspection and Survey (INSURV) spent time onboard evaluating the ship’s performance. Now shipbuilders will put the final fit-and-finish touches on the ship in preparation for delivery in May.

Major evolutions during acceptance trials include the anchor-handling demonstration, ballast/deballast demonstration, detect-to-engage exercise, running the ship at full power and steering.

«It took a lot of work for the folks to complete these sea trial evolutions, and the ship answered every task and performed well», said George S. Jones, Ingalls’ vice president of operations. «Every single skill needed to build this amphibious ship was on display for the INSURV board to see. Our people and this ship did not disappoint. I would also like to thank our partners at Supervisor of Shipbuilding, Gulf Coast for this joint effort».

LPD-26 is named in honor of the late John P. Murtha, who represented Pennsylvania’s 12th Congressional District from 1974 to 2010. In addition to his tenured history in the House of Representatives, Murtha was also a veteran of the U.S. Marine Corps and Reserves. He served for 37 years and received the Bronze Star with Combat «V», two Purple Hearts and the Vietnamese Cross of Gallantry for his service in the Vietnam War. He retired as a colonel in 1990.

Ingalls has built and delivered nine ships in the San Antonio-class. In addition to USS John P. Murtha (LPD-26), Ingalls has the 11th LPD, USS Portland (LPD-27), under construction. Portland launched on February 13 and will be christened on May 21. Ingalls has received advance procurement funding for long-lead-time material for the 12th ship in the class, USS Fort Lauderdale (LPD-28).

The San Antonio-class is the latest addition to the U.S. Navy’s 21st century amphibious assault force. The 684-foot-long/208 meter-long, 105-foot-wide/32-meter-wide ships are used to embark and land Marines, their equipment and supplies ashore via air cushion or conventional landing craft and amphibious assault vehicles, augmented by helicopters or vertical takeoff and landing aircraft such as the MV-22 Osprey. The ships support a Marine Air Ground Task Force across the spectrum of operations, conducting amphibious and expeditionary missions of sea control and power projection to humanitarian assistance and disaster relief missions throughout the first half of the 21st century.

«Overall the builder’s trial was successful, and the ship performed well», said Kari Wilkinson, Ingalls’ LPD-26 program manager. «This shipbuilding milestone is another accomplishment for a seasoned LPD production and test team that is ready to continue the learning on future LPD platforms. This team understands the important mission LPDs provide to our nation, and we look forward to delivering another fine, much-needed asset to our sailors and Marines».

Major evolutions during builder’s trials include the anchor-handling demonstration, ballast/deballast demonstration, detect-to-engage exercise, running the ship at full power and steering.

Shipbuilders will now prepare USS John P. Murtha (LPD-26) for acceptance trials in April to demonstrate the same tests and operational success to the U.S. Navy’s Board of Inspection and Survey (INSURV). The ship is scheduled to be delivered to the U.S. Navy in the second quarter of 2016.

«LPD-26 experienced an excellent builders trials», said George S. Jones, Ingalls’ vice president of operations. «This is another fine testament to the dedicated men and women of Ingalls shipbuilding and their shipbuilding talents. The USS John P. Murtha (LPD-26) is a quality ship, and the ability to deliver her on schedule later this year is a result of great craftsmen and the outstanding Navy partnership we have with the Supervisor of Shipbuilding, Gulf Coast».

LPD-26 is named in honor of the late John P. Murtha, who represented Pennsylvania’s 12th Congressional District from 1974 to 2010. In addition to his tenured history in the House of Representatives, Murtha was also a veteran of the U.S. Marine Corps and Reserves. He served for 37 years and received the Bronze Star with Combat «V», two Purple Hearts and the Vietnamese Cross of Gallantry for his service in the Vietnam War. He retired as a colonel in 1990.

Ingalls has built and delivered nine ships in the San Antonio-class. In addition to USS John P. Murtha (LPD-26), Ingalls has the 11th LPD, USS Portland (LPD-27), under construction. USS Portland (LPD-27) launched on February 13 and will be christened on May 21. Ingalls received a $200 million advance procurement contract for the 12th ship in the class, LPD-28, in December 2015.

The San Antonio-class is the latest addition to the U.S. Navy’s 21st century amphibious assault force.

«It takes a tremendous effort by all of our crafts personnel to accomplish this big milestone», said Bruce Knowles, Ingalls’ LPD-27 program manager. «The LPD program continues to improve with each ship, and LPD-27 falls into that same line of success proven by a hot production line. Our shipbuilders continue to build these ships more efficiently and affordably».

USS Portland (LPD-27) was translated via Ingalls’ rail car system to the floating dry dock prior to launch. The dock was moved away from the pier and then flooded to float the ship. With the assistance of tugs, Portland came off the dock on Saturday morning.

Ingalls has built and delivered nine ships in the San Antonio class of ships, with USS John P. Murtha (LPD-26) and USS Portland (LPD-27) remaining. Ingalls received a $200 million advance procurement contract for LPD-28, the 12th ship in the class, in December, 2015.

Christening of John

The USS John P. Murtha (LPD-26) was christened at Ingalls Shipbuilding on Saturday, March 21. The vessel is named after the late U.S. Rep. John Murtha, a Democrat from the 12th district, who was the longest-serving congressman in Pennsylvania history. His daughter, Donna Murtha, sponsored the ship and performed the traditional breaking of a bottle of American sparkling wine across the ship’s bow.

For safety reasons, the bottle of sparkling wine is encased in sheetmetal in the Ingalls shops and wrapped by a shipbuilder in decorative ribbons of red, white and blue

House Democratic Leader Nancy Pelosi, D-California, was the featured speaker at the ceremony. «Jack Murtha poured everything – everything he was, everything he had – into the service of our country and the lives of the American people», she said of her colleague, who represented Pennsylvania’s 12th Congressional District for 36 years until his death in 2010. «To watch Chairman Murtha legislate was to see a master at work, but more indicative of his character was to watch him communicate with our men and women in uniform, whether on the battlefield or at their bedside. He knew how serious a responsibility it is to send our men and women into harm’s way, and he was unwavering in his conviction that we must honor their sacrifice not only with our words but our deeds. Like its namesake, the John P. Murtha will provide our servicemen and women the means to enter the battle and to make their way back home», Pelosi continued. «Congratulations to Ingalls Shipbuilding and all of the hard-working men and women who have put their skill and determination into this ship and this special day».

Murtha’s daughter, Donna S. Murtha, is the ship sponsor. At the culmination of the ceremony, she smashed a bottle of sparkling wine across the bow of the ship, officially christening LPD 26 as the John P. Murtha. «May God bless this ship and all who sail in her», she said.

HII President and CEO Mike Petters also spoke at the ceremony. «Ingalls is building each ship better than the last, and the team’s performance – and the performance of the delivered LPDs – has strengthened the nation’s confidence in the LPD program», he said. «This was most recently demonstrated by the Navy’s request and the Congressional investment in the 12th San Antonio-class warship – and the Navy’s selection of this proven hull-form for its new LX(R) class of amphibious ships. Ingalls is making a difference».

«The ship we christen today honors Congressman John P. Murtha, who proudly served his country as both a Marine and a statesman for almost 40 years», said Ingalls Shipbuilding President Brian Cuccias. «I can’t imagine a more fitting namesake to represent the marvel of American technology, craftsmanship and strength that is LPD-26. Ingalls shipbuilders know that quality matters. We build our warships as though our own sons and daughters will take them into harm’s way – because they may. And because we owe our warfighters our very best. Our shipbuilders put their hearts and souls into every ship we build – as we have for generations. LPD-26 is no exception. Murtha was the most complete and lowest-cost LPD when she was launched, with many key systems finished months ahead of our historical best. So I’m extremely proud of our LPD-26 shipbuilders».

«Deep in the hull or on scaffolding hundreds of feet in the air – in the Deep South heat – these Mississippians are welding, painting and assembling the living quarters, galley, hospital and the command centers for those who serve», said Mississippi Lt. Gov. Tate Reeves. «You can see their commitment to a job well done – because they know the invaluable role they play in America’s national security».

John P. Murtha (LPD-26)

The amphibious transport dock ship John P. Murtha (LPD-26) is the tenth ship in the San Antonio Class. LPD-26 is named in honor of Congressman John P. Murtha, who represented Pennsylvania’s 12th Congressional District for 36 years – from 1974 until his death in 2010. In addition to his tenured history in the House of Representatives, Murtha was also a veteran of the United States Marine Corps and Reserves. He served a distinguished 37 years, receiving the Bronze Star with Combat «V», two Purple Hearts and the Vietnamese Cross of Gallantry for his service in the Vietnam War. He retired as a colonel in 1990.

Amphibious transport dock ships (LPD) are warships that embark, transport, and land elements of a landing force for a variety of expeditionary warfare missions. LPDs are used to transport and land Marines, their equipment and supplies by embarked Landing Craft Air Cushion (LCAC) or conventional landing craft (Landing Craft Utility, LCU) and Expeditionary Fighting Vehicles (EFV) or Amphibious Assault Vehicles (AAV) augmented by helicopters or vertical take-off and landing aircraft (MV-22). These ships support amphibious assault, special operations or expeditionary warfare missions and can serve as secondary aviation platforms for amphibious ready groups.

Collectively, the San Antonio LPD-17 class ships will functionally replace more than 41 amphibious ships (LPD-4, LSD-36, LKA-113 and LST-1179 classes of amphibious ships) providing the U.S. Navy and Marine Corps with modern, seabased platforms that are networked, survivable, and built to operate with 21st century transformational platforms, such as the MV-22 Osprey aircraft, the Expeditionary Fighting Vehicle (EFV), and future means by which Marines are delivered ashore.

A contract for final design and construction of San Antonio (LPD-17), the lead ship in the class, was awarded in December 1996; actual construction commenced in June 2000. USS San Antonio was delivered to the Navy in July 2005. LPDs 18-25 have also been delivered to the U.S. Navy. New York (LPD-21) is the first of three LPD 17-class ships built in honor of the victims of the September 11, 2001, terrorist attacks.

The ships bow stem was constructed using 7.5 tons of steel salvaged from the World Trade Center. The Navy named the 8th and 9th ships of the class – Arlington and Somerset – in honor of the victims of the attacks on the Pentagon and United Flight 93, respectively. Materials from those sites were also incorporated into Arlington and Somerset.

LPDs 26-27 are currently under construction at Huntington Ingalls Industries (HII) on the Gulf Coast, and will deliver over the next few years. The keel of LPD-27 was laid in August 2013, LPD-26 was launched in October 2014. In fiscal year 2015, the purchase of long lead-time materials for LPD-28 was approved.
