BAE shipyard sues Navy over extra work on USS Bataan
BAE Systems' Norfolk shipyard is suing the Navy's Mid-Atlantic Regional Maintenance Center, claiming the yard is owed nearly $1.1 million for work it did on USS Bataan.
The lawsuit contends that the Navy is refusing to pay for extra work that BAE and its subcontractors had to perform because the Navy didn't provide necessary supplies or complete needed work while Bataan was in the BAE shipyard.
BAE won a $51.6 million, fixed-price contract to repair and modernize Bataan in September 2017. It was originally supposed to complete the work in July 2018, but that was extended to November 2018.
When the ship was not delivered by then, the Navy declared BAE in default of the contract. BAE continued to work on the ship until March 2019.
The lawsuit alleges that the Navy's challenges securing funds for additional work delayed completion. In addition, the lawsuit says the Navy's continued dumping of liquids into the bilge spaces prevented BAE from completing cleaning and pumping work.
It also alleges that the Navy also expanded the work required, as when it directed the yard to add multiple pendant and wire installations on the Flight Deck Safety Nets.
BAE said most of its claims for payment for the additional work were denied by the Navy's Contracting Officer in a formal final decision, prompting the shipyard to sue for the funds it claims it is owed.
The Navy maintenance center has not yet filed a formal response to the BAE complaint. A spokesman was not immediately available for comment.

Northrop to build 3D-printed scramjet engine for Raytheon hypersonic weapon
By: Valerie Insinna LE BOURGET, France — Raytheon has partnered with Northrop Grumman on its air-breathing hypersonic weapon, which will be powered by a Northrop-made scramjet made entirely of 3D-printed parts, the company announced Tuesday. Raytheon and Northrop's weapon is one of the competitors in the U.S. Defense Advanced Research Projects Agency's HAWC project, short for Hypersonic Air-Breathing Weapon Concept. The companies' offering — which comprises Northrop's scramjet engine and Raytheon's air vehicle — is ready to make its first flight, said Tom Bussing, vice president of Raytheon's advanced missile system segment. “We have a flight test planned for the near future where we will begin flying this particular class of weapon system,” he said during a briefing at Paris Air Show. While the exact schedule is classified, Bussing noted that the companies have already conducted “significant” ground tests “The combustor, everything that we do now is done by additive manufacturing, so its driving affordability into the hypersonic boost missile's scramjet engine. We are also looking at ways to reduce the weight so we can have more fuel, more payload,” he said. The entirety of Northrop's scramjet is 3D printed using advanced materials, said John Wilcox, the company's vice president of advanced programs and technology. “There gets to be points where you have to weld additive manufactured parts, but right now even the full combustor [is printed],” he said. “We think we're the first to ever 3D print a full combuster for an air-breathing scramjet engine. That's what's going to drive the affordability for air-breathing scramjet missiles.” According to Raytheon, scramjet engines use high vehicle speeds to then compress air moving into its inlets before combusting it. The process allows a vehicle to maintain hypersonic speeds — more than five times the speed of sound — over longer periods of time. The Raytheon-Northrop team is competing against Lockheed Martin for the final HAWC contact. https://www.defensenews.com/digital-show-dailies/paris-air-show/2019/06/18/northrop-to-build-3d-printed-scramjet-engine-for-raytheon-hypersonic-weapon/
