Huntington Ingalls’ Newport News Shipbuilding division has partnered with 3D Systems to develop additive manufacturing technologies expected to accelerate the adoption of metal 3-D printing in the naval shipbuilding industry.
The joint effort is expected to support future qualification and certification programs necessary to implement 3D printing technology for the U.S. Navy and further revolutionize how shipbuilders build the next generation of warships. It is also part of a significant technological transformation underway at Newport News called integrated Digital Shipbuilding (iDS).
Additive manufacturing involves the layer-by-layer fabrication of raw materials into a finished product, as compared to traditional manufacturing which uses a subtractive processes, such as cutting or grinding metal.
“This is a game-changing and disruptive technology for our industry,” said Charles Southall, Newport News’ vice president of engineering and design. “In addition to our ongoing digital shipbuilding efforts, 3-D printing could transform our design standards, and this technology has the potential to be one of the most significant manufacturing innovations in our industry since we began building nuclear-powered ships in the 1950s.”
As part of the joint development agreement, 3D Systems delivered and installed the ProX DMP 320 high-performance metal additive manufacturing system at Newport News. The state-of-the-art machine is capable of making three-dimensional, marine-based, alloy parts for castings or other fabricated parts, such as valves, housings and brackets.
“3D Systems is pleased to play an integral role in transforming the naval shipbuilding industry,” said Kevin McAlea, executive vice president and general manager, metals and healthcare, at 3D Systems. “The ProX DMP 320 printer system, combined with our team’s expertise in metal 3-D printing technology, will bring new digitally enhanced geometries to Newport News Shipbuilding, enabling higher performing warship components and ultimately more efficient cost-effective parts delivery to the U.S. Navy.”
The partnership is said to represent a significant step forward in the fabrication of components and material for future warships. Compared to traditional manufacturing methods that involve the conversion of raw materials into a finished product through subtractive processes, such as cutting or grinding metal, additive manufacturing involves the layer-by-layer fabrication of raw materials into a finished product.
“One of our goals is to provide leadership to our supplier base that will help accelerate the adoption of additive manufacturing within our industry, which may improve efficiencies and quality,” Southall said. “We look forward to working with key technology leaders, such as 3D Systems, to help to break down technology adoption barriers and advance additive manufacturing in our industry and supply chain.”

United Kingdom-based maritime services provider Inchcape Shipping Services has agreed to pay $20 million to settle a U.S. government lawsuit alleging it had overbilled the U.S. Navy for ship husbanding services in ports around the world, the U.S. Justice Department announced Tuesday.
As a ship husbanding contractor, Inchcape and some of its subsidiaries provided U.S. Navy ships with food and other subsistence items, waste removal, telephone services, ship-to-shore transportation, force protection services and local transportation at ports in several regions, including southwest Asia, Africa, Panama, North America, South America and Mexico.
A lawsuit filed in 2015 alleged that from 2005 to 2014, Inchcape violated the False Claims Act by knowingly overbilling the Navy for these services by submitting invoices that overstated the quantity of goods and services provided, billing at rates in excess of applicable contract rates, and double-billing for some goods and services, the Justice Department said in a press release announcing the settlement.
“Federal contractors may only charge the government for costs allowed by their federal contracts,” said Acting Assistant Attorney General Chad A. Readler, head of the Justice Department’s Civil Division. “The Department of Justice will take action against contractors that knowingly submit inflated claims to the armed forces—or any other agency of the United States—as those inflated claims wrongfully divert taxpayer dollars.”
The original lawsuit was brought under the qui tam, or whistleblower, provisions of the False Claims Act by three former employees of Inchcape.
Under the act, a private citizen may bring suit on behalf of the United States and share in any recovery. As part of Tuesday’s resolution, the whistleblowers will receive approximately $4.4 million, the Justice Department said.
“This settlement demonstrates that the Department of the Navy will continue to hold contractors accountable for the agreements they make to supply our fleet,” said Secretary of the Navy Richard V. Spencer. “The Department expects strict adherence to higher standards within the Department and expects the same from its contractors.”

U.S. Pacific Command Changes Name in Symbolic Nod to India

By Idrees Ali PEARL HARBOR, Hawaii, May 30 (Reuters) – The U.S. military on Wednesday renamed its Pacific Command the U.S. Indo-Pacific Command, in a largely symbolic move underscoring the growing importance of India to the Pentagon, U.S. officials said.
U.S. Pacific Command, which is responsible for all U.S. military activity in the greater Pacific region, has about 375,000 civilian and military personnel assigned to its area of responsibility, which includes India.
“Relationships with our Pacific and Indian Ocean allies and partners have proven critical to maintaining regional stability,” U.S. Defense Secretary Jim Mattis said in prepared remarks.
“In recognition of the increasing connectivity between the Indian and Pacific Oceans, today we rename the U.S. Pacific Command to U.S. Indo-Pacific Command,” Mattis said.
He was speaking during a change of command ceremony. Admiral Philip Davidson was assuming leadership of the command from Admiral Harry Harris, who is President Donald Trump’s nominee to be ambassador to South Korea.
The renaming does not mean additional assets will be sent to the region at this time, but rather recognizes India’s increasing military relevance for the United States.
In 2016, the United States and India signed an agreement governing the use of each other’s land, air and naval bases for repair and resupply, a step toward building defense ties as they seek to counter the growing maritime assertiveness of China.
The United States is also keen to tap into India’s large defense market. It has emerged as India’s No. 2 weapons supplier, closing $15 billion worth of deals over the last decade.
Mattis has been pushing for a waiver for countries like India, after Trump signed a law last year which said that any country trading with Russia’s defense and intelligence sectors would face sanctions.
“I think India and the relationship with the United States is the potentially most historic opportunity we have in the 21st-century and I intend to pursue that quite rigorously,” Davidson, the incoming head of the command, said last month.
However, experts said the name change would mean little unless it was tied to a broader strategy.
“Renaming PACOM is ultimately a symbolic act … (it) will have a very limited impact unless the U.S. follows through with a significant array of initiatives and investments that reflect a wider aperture,” said Abraham Denmark, a former deputy assistant secretary of defense for East Asia under President Barack Obama.

Price Hikes, Production Delays Mark Navy Shipbuilding for Past Decade
By: Ben Werner

Navy shipbuilding has been plagued for the last decade by programs running over-budget and underperforming once completed, according to a new government report, resulting in a smaller fleet than previously planned.
However, the Navy’s pace of shipbuilding during the past decade barely kept pace with the rate of decommissioning ships. The Navy’s 283-ship fleet of today is a mere two hulls more than the 281-ships the Navy had at the end of 2006, and is 50 ships shy of the 330-ship fleet the Navy in 2007 predicted would be operating today, according to the report.
“Cost growth has contributed to the erosion of the Navy’s buying power with ship costs exceeding estimates by over $11 billion during this time frame. Additionally, the Navy’s shipbuilding programs have had years of construction delays and, even when the ships eventually reached the fleet, they often fell short of quality and performance expectations,” the report states.
The report evaluated the cost and outcomes of 11 shipbuilding programs, including both variants of the the Littoral Combat Ship, the Arleigh Burke-class guided-missile destroyer (DDG-51), the Zumwalt-class destroyer (DDG-1000), the America-class amphibious assault ship (LHA-6), the San Antonio-class amphibious transport dock (LPD-17), the Virginia-class attack submarine (SSN-774), the Gerald R. Ford-class nuclear aircraft carrier (CVN-78), the Expeditionary Fast Transport (EPF), the Expeditionary Transfer Dock/Expeditionary Sea Base (ESD/ESB), and the Lewis and Clark-class dry cargo/ ammunition ship (T-AKE).
The GAO studied the outcomes of eight first-in-class ship designs and found all were provided to the fleet behind schedule, with four of these ships arriving more than two years late. USS Zumwalt (DDG-1000) was the tardiest, arriving six years behind schedule.
During the past decade, the GAO has issued 26 reports, identified shipbuilding best practices for the Navy to implement, testified before Congress on several occasions, and made 67 recommendations to help the Navy improve its shipbuilding programs. The Navy has implemented 29 of the 67 recommendations. As for the shipbuilding best practices identified by the GAO, in many cases the Navy has agreed with these GAO suggestions but has yet to implement the ideas, the report states.
The result of this failure to take actions is that eight of the ship programs studied blew through their initial budgets. CVN-78, DDG-1000, LHA-6, SSN-74, T-AKE-1, LCS-1, LCS-2, and LPD-17 were all over-budget, with three programs – the LCS-1, LCS-2, and LPD-17 – exceeding their initial budgets by 80 to 150 percent.
The GAO found the Navy’s anticipated cost-savings were often overly optimistic. Construction delays due to the Navy changing requirements caused costs to increase. The Navy practice of accepting delivery of ships with significant deficiencies also drove up costs because these ships required extensive work, and more money, before being deemed combat-ready.
In the case of the first-in-class USS Gerald R. Ford (CVN-78), the GAO report found the Navy’s original cost and schedule estimates did not fully account for the risks associated with building a first-in-class ship using new technology, nor did the Navy account for how long new technologies would take to install. The Navy even under-calculated the amount of labor needed to build the ship, estimating fewer labor hours than required for the last two Nimitz-class carriers, the GAO states.
“The Navy took delivery of CVN-78 in May 2017, but the carrier will not be ready to deploy until 2022 as significant development, construction, and testing continues,” the GAO report states.
While cost-overruns are an expected part of building a first-in-class ship, the GAO report found follow-on ships in several classes also cost more than originally expected. In the case of Ford-class carriers, the GAO report states, “Costs for CVN-79 are likely to exceed the $11.4 billion estimate.”
A more disciplined approach to shipbuilding will help control costs in the future, the GAO report states. Suggestions include aligning achievable capabilities with available funding and allowing new technologies to mature before incorporating them into ship programs.
Despite all the recommendations, the GAO does not consider the Navy’s current shipbuilding plans to have changed much from the past.
“Though the Navy has started to make some improvements, its current approach to shipbuilding leaves it at risk of continually losing buying power and jeopardizes its ability to achieve its long-range shipbuilding goals,” the GAO report states.
