BAE wins Marine Corps contract to build new amphibious combat vehicle
WASHINGTON — BAE Systems has won a contract to build the Marine Corps' new amphibious combat vehicle following a competitive evaluation period where BAE's vehicle was pitted against an offering from SAIC.
The contract allows for the company to enter into low-rate initial production with 30 vehicles expected to be delivered by fall of 2019, valued at $198 million.
The Marines plan to field 204 of the vehicles. The total value of the contract with all options exercised is expected to amount to about $1.2 billion.
The awarding of the contract gets the Corps “one step closer to delivering this capability to the Marines,” John Garner, Program Executive Officer, Land Systems Marine Corps, said during a media round table held Tuesday.
But the Corps isn't quite done refining its new ACV. The vehicle is expected to undergo incremental changes with added new requirements and modernization.
The Corps is already working on the requirements for ACV 1.2, which will include a lethality upgrade for the amphibous vehicle.
BAE's ACV vehicle will eventually replace the Corps' legacy amphibious vehicle, but through a phased approach. The Assault Amphibious Vehicle is currently undergoing survivability upgrades to keep the Cold War era vehicle ticking into 2035.
BAE Systems and SAIC were both awarded roughly $100 million each in November 2015 to deliver 16 prototypes to the Marine Corps for evaluation in anticipation of a down select to one vendor in 2018.

All government testing of the prototypes concluded the first week of December 2017 and the Marine Corps issued its request for proposals the first week in January 2018. Operational tests also began concurrently.
Government testing included land reliability testing, survivability and blast testing and water testing — both ship launch and recovery as well as surf transit.
Operational evaluations included seven prototypes each from both SAIC and BAE Systems, six participated and one spare was kept for backup.
BAE Systems' partnered with Italian company Iveco Defense Vehicles to build its ACV offering.

Some of the features BAE believed were particularly attractive for a new ACV is that it has space for 13 embarked Marines and a crew of three, which keeps the rifle squad together. The engine's strength is 690 horsepower over the old engine's 560 horsepower, and it runs extremely quietly. The vehicle has a V-shaped hull to protect against underbody blasts, and the seat structure is completely suspended.
SAIC's vehicle, which was built in Charleston, South Carolina, offered improved traction through a central tire-inflation system to automatically increase or decrease tire pressure. It also had a V-hull certified during tests at the Nevada Automotive Test Center — where all prototypes were tested by the Marine Corps — and had blast-mitigating seats to protect occupants.
The 3rd Assault Amphibian Battalion, 1st Marine Division out of Camp Pendleton, California, is expected to receive the first ACV 1.1 vehicles.

US Air Force may have accidentally revealed interest in hypersonic nuke
By: Valerie Insinna WASHINGTON — The U.S. Air Force has issued, and quietly revoked, a solicitation to industry seeking technologies that would support a hypersonic glide vehicle capable of traversing intercontinental ranges, potentially signaling the military's interest in a hypersonic nuclear weapon. According to an Aug. 12 request for information first reported by Aviation Week, the Air Force Nuclear Weapons Center sought ideas for potential upgrades to intercontinental ballistic missiles, including a “thermal protection system that can support [a] hypersonic glide to ICBM ranges.” The items listed as potential ICBM upgrades were all marked “unclassified/for official use only,” which notes information that — while not secret — is not normally released to the public. The RFI was then withdrawn after Aviation Week began inquiring about it, the report noted. Asked about the RFI on Wednesday, Lt. Gen. Richard Clark, the Air Force's deputy chief of staff for strategic deterrence and nuclear integration, said the service's next-generation ICBMs — known as the Ground Based Strategic Deterrent — will not be available as a hypersonic variant when it is fielded in the late 2020s. “With a weapon system that's going to be fielded until the 2070 time frame, it's hard to know exactly where we may go with that down the road,” he during an event hosted by the Mitchell Institute for Aerospace Studies. “Right now, though, the threshold warhead does not include hypersonic glide vehicles. I think I can say that safely without talking too much about what the warheads will look like.” However, he noted that GBSD's open-architecture backbone makes it able to adopt emerging technologies. He did not comment specifically on whether a hypersonic glide vehicle was under consideration. As we bring the system online, we will ensure that we have the ability to roll different technologies in and to incorporate that into GBSD,” he said. “And that's one of the, I think, best features ... of GBSD, is that it's going to give us that flexibility. So that if we decide down the road that there's a particular technology that needs to be incorporated, we'll be able to do that.” As the sole bidder in the GBSD competition, Northrop Grumman is expected to win an estimated $85 billion over the life of the program. A contract award is slated to occur by September, although Northrop CEO Kathy Warden said in April that she expected a decision this month. https://www.defensenews.com/smr/nuclear-arsenal/2020/08/19/the-air-force-might-be-eyeing-a-hypersonic-nuclear-weapon/
