«Today is a great day for this collective industry and customer team», said Kari Wilkinson, Ingalls’ vice president, program management. «For many of the shipbuilders, Supervisor of Shipbuilding representatives and members of the U.S. Navy program office, this is the 11th ship they have built and delivered together. Their personal commitment to excellence has become the hallmark of the LPD program, and we are positioned to continue that tradition on future ships».

USS Portland (LPD-27) was delivered during an afternoon ceremony with shipbuilders, ship’s force and representatives of Supervisor of Shipbuilding Gulf Coast together in attendance. The signing of the DD 250 document officially transfers custody of the ship from HII to the U.S. Navy.

«I am amazed with the shipbuilders here at Ingalls», said Captain J.R. Hill, Portland’s prospective commanding officer. «There are thousands of them who have been working to build this ship and put it into service, and they’ve really done a great job. I’m very impressed with the team Ingalls has put together as well as the 370 crew members present today who are ecstatic about taking control of this ship. We look forward to what she can do in the future».

USS Portland (LPD-27) is named for the largest city in the state of Oregon. The state has a long history with the U.S. Navy, going back to the construction of hundreds of World War II Liberty and Victory ships at three Portland-area shipyards.

Ingalls has delivered 11 San Antonio-class ships to the U.S. Navy and currently has one more, USS Fort Lauderdale (LPD-28), under construction. In June, Ingalls received an advance procurement contract from the Navy to provide long-lead-time material and advance construction activities for LPD-29, the 13th ship of the San Antonio class.

The San Antonio class is the latest addition to the U.S. Navy’s 21st century amphibious assault force. The 684-foot-long, 105-foot-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.

Acceptance Sea Trials

Huntington Ingalls Industries (HII) announced on August 21 the successful completion of acceptance sea trials for the amphibious transport dock USS Portland (LPD-27). The San Antonio-class ship, built at HII’s Ingalls Shipbuilding division, spent last week with the U.S. Navy’s Board of Inspection and Survey (INSURV), performing more than 200 trial events that included both in-port and underway portions.

«These sea trials provide an opportunity to showcase the ship’s tremendous capabilities and the build and test skills of our shipbuilders», Ingalls President Brian Cuccias said. «The success of these milestones is important as we continue to remain competitive and keep our supplier base and production lines active in the construction of these quality amphibious warships».

Key demonstrations performed during acceptance trials for INSURV by the Ingalls’ test and trials team included: the anchor-handling demonstration, ballast/de-ballast demonstration, detect-to-engage exercise, running the ship at full power and steering. Now Ingalls’ shipbuilders will put their final touches on the ship in preparation for delivery this year.

«Our team puts in a lot of hard work and effort to make these sea trials successful», said George Jones, Ingalls’ vice president of operations. «We get better with every LPD we build, and we look forward to delivering a very complex and capable ship to our sailors and Marines. As always, this success was a joint effort between our shipbuilders, test and trials team and our partners at Supervisor of Shipbuilding, Gulf Coast».

USS Portland (LPD-27) is named for the largest city in the state of Oregon. The state has a long history with the U.S. Navy, going back to the construction of hundreds of World War II Liberty and Victory ships at three Portland-area shipyards.

Ingalls has delivered 11 San Antonio-class ships to the U.S. Navy, including USS John P. Murtha (LPD-26) in 2016. In June, Ingalls received an advance procurement contract from the U.S. Navy to provide long-lead-time material and advance construction activities for LPD-29, the 13th amphibious transport dock of the San Antonio class. Ingalls will lay the keel of the 12th San Antonio-class ship, USS Fort Lauderdale (LPD-28), this fall.

«Portland’s successful sea trial proves the dedication and quality of work our shipbuilders continue to provide to the LPD program», said Steve Sloan, Ingalls’ LPD program manager. «I’m proud of the performance of the shipbuilders and the ship during acceptance trials, and now we will continue to work the final fit-and-finish touches before LPD 27’s delivery this fall».

The San Antonio class is a major part of 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.

«This successful sea trial is another testament to the quality work our shipbuilders continue to provide in the LPD program», said Ingalls Shipbuilding President Brian Cuccias. «These are complex vessels, and I’m proud of our workforce, who have the skills and knowledge it takes to design, build and test these American warships».

Major testing conducted during builder’s trials include anchor-handling, ballast/de-ballast of the ship’s well deck, detect-to-engage, full power ahead and astern and steering demonstrations.

«We place great importance on our relationships with our customers and the responsibility we have to the sailors and Marines who will own this ship», said Kari Wilkinson, Ingalls’ vice president of program management. «The LPD team is strong and very prepared to continue providing these capable assets to our country».

Ingalls’ shipbuilders are now preparing Portland for acceptance trials in August, when the U.S. Navy’s Board of Inspection and Survey (INSURV) will conduct inspections and witness final demonstrations before the ship is delivered to the U.S. Navy.

«Our shipbuilders continue to work in concert with one another, and this ship is another example of their successes», said George Jones, Ingalls’ vice president of operations. «We have the best construction team in our industry today, and this team, along with the nationwide supplier base, will continue to see more successes with their winning behaviors and team spirit».

LPD-27 will be the third U.S. Navy ship named Portland, honoring both the Oregon seaport and Maine’s largest city.

Ingalls has delivered 10 San Antonio-class ships to the Navy, including USS John P. Murtha (LPD-26) in 2016. Ingalls will lay the keel of the 12th San Antonio-class ship, USS Fort Lauderdale (LPD-28), this fall. Last Friday, Ingalls was awarded an advance procurement contract for LPD-29.

The San Antonio class is a major part of the Navy’s 21st century amphibious assault force.

Christening of Portland

Huntington Ingalls Industries’ (HII) Ingalls Shipbuilding division christened the amphibious transport dock USS Portland (LPD-27) on May 21 in front of approximately 1,000 guests. U.S. Marine Corps Major General Christopher Owens, director of the U.S. Navy’s expeditionary warfare division, was the keynote speaker. «Marines love these ships», he said. «They are perhaps the most versatile ships in the fleet. And in this current era when the United States faces a variety of threats and potential crises across the globe, LPDs uniquely enable the Navy and Marine Corps team to adapt and respond to a full range of scenarios we might face».

USS Portland (LPD-27), the 11th San Antonio-class amphibious transport dock, is named for the largest city in the state of Oregon. The state has a long history with the U.S. Navy, going back to the construction of hundreds of World War II Liberty and Victory ships at three Portland-area shipyards. Bonnie Amos, wife of retired Marine Corps Commandant General James Amos, is the ship’s sponsor and smashed a bottle of sparkling wine across the bow of the ship, officially christening Portland. «Today is about Ingalls shipbuilders», she said. «Today is about the pride in what has transpired to make this ship, LPD-27, the greatest ship and the best in her class».

Ingalls has delivered 10 San Antonio-class ships to the U.S. Navy with the most recent, USS John P. Murtha (LPD-26), delivering on May 13. Ingalls has received more than $300 million in advance procurement funding for the 12th ship in the class, USS Fort Lauderdale (LPD-28).

«Portland is the 11th ship in the San Antonio class, and she is the best LPD to date», Ingalls Shipbuilding President Brian Cuccias said. «Working closely with our Navy partner, we continue to improve on each ship we build. We’re investing, along with the great state of Mississippi and the Navy, in modernizing our facilities. Combine that with a hot production line and our talented and experienced shipbuilders, and we are uniquely positioned to provide our country with the highest-quality, most capable ships in our Navy’s fleet».

LPD-27 is the third ship named Portland. The first USS Portland (CA-33) was the lead ship of a new class of heavy cruisers. Launched in 1932, it was named after the city of Portland, Maine, and saw battle during World War II. The second USS Portland (LSD-37), an amphibious landing ship commissioned in 1970, was named after both Portland, Maine and Oregon. She completed 14 deployments to the Caribbean, Mediterranean and North Atlantic.

«Our number one congressional responsibility is the common defense of this nation», said Representative Steven Palazzo, Republican Party-Mississippi. «Part of our national defense includes amazing ships like the LPD-27 San Antonio-class amphibious ship. With the daily occurrence of global threats, it’s obvious we don’t need just more ships, but ships that are survivable and capable. After all, they carry America’s most precious treasure, our men and women in uniform».

The San Antonio class is the latest addition to the 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.

«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.

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.
