BAE wins Marine Corps contract to build new amphibious combat vehicle
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.
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. ... t-vehicle/

April 2018
Program Should Take Steps to Ensure Manufacturing Readiness
With regard to schedule, the ACV program has made no major changes to the acquisition schedule since GAO previously reported on the program in April 2017. ACV 1.1 program officials are in the process of preparing to down-select to a single contactor and enter low-rate production in June 2018, start a second round of low rate production the following year, and begin full-rate production in 2020. ACV 1.1 may be followed by the acquisition of other versions (ACV 1.2 and ACV 2.0) with advanced capabilities such as higher water speeds.

The ACV program is preparing to start production of ACV 1.1, which includes determining that the contractors’ manufacturing capabilities are sufficiently mature. However, program officials are considering entering production with a lower level of manufacturing maturity than called for in Department of Defense (DOD) guidance or GAO identified best practices.

The ACV is being developed as a partial or full replacement for the AAV, which is a tracked (non-wheeled) vehicle with capability to launch from ships to reach the shore carrying up to 21 Marines at a speed of up to approximately 6 knots. This speed effectively limits its range for traveling from ship to shore to no farther than 7.4 nautical miles. In order to upgrade the AAV to meet current threats and establish a path toward an enhanced platform, DOD and the Marine Corps implemented an incremental approach. The first step was to improve the AAVs’ protection from threats such as improvised explosive devices by installing enhanced armor and other equipment—referred to as survivability upgrades—efforts which are currently underway. The second step was to establish a plan to replace the AAV with a new vehicle, the ACV, which would develop and enhance capabilities in three incremental steps:
  • ACV 1.1 would be a wheeled vehicle that provides improved protected land mobility but limited amphibious capability. In operations, it is expected to be part of an amphibious assault through the use of a surface connector craft to travel from ship to shore. This increment would leverage prototypes, demonstration testing, and other study results from the previously suspended Marine Personnel Carrier program.
  • ACV 1.2 would have improved amphibious capability, including the ability to self-deploy and swim to shore. The development phase of the second ACV increment (ACV 1.2) is scheduled to begin in February 2019.
  • ACV 2.0 would focus on exploring technologies to attain higher water speed capability.

Gerade erst ausgewählt - und schon wird herumgesudert:

The USMC Is Buying New Amphibious Vehicles That Can't Swim Faster Than What They Have Now
But the wheeled design isn't any faster than that the service’s Cold War-era tracked Assault Amphibious Vehicle family in the water and there are serious questions about whether it offers enough other improvements to avoid having to buy a third type in the near future.
The 8x8 SuperAV has a weight of around 20 tons depending on its configuration and can hit top speeds of up to 65 miles an hour on improved roads, which makes it significantly faster than the AAV on land. The two vehicles have similar speeds – both less than 10 miles per hour – in the water and the old tracked design may actually turn out to be marginally faster.

The ACV 1.1 will be able to carry a full squad of 13 Marines, which was an important selling point over Terrex, but this is almost half the capacity of one AAV. The vehicle does offer superior protection against mines and roadside bombs over the tracked vehicles thanks to a V-shaped underbody that deflects the blast away from the hull and a suspended, flexible seating system that better absorbs the shock.
It’s not clear that the SuperAV is the most cost-effective option, though. Each one has a price tag of at least $4 million and it’s not clear what weapons, defensive systems, or other equipment that figure includes.
There’s no guarantee that the ACV 1.1 will retain its performance advantages over the AAVs as it will almost certainly end up burdened by additional defensive systems and other equipment. Wheeled vehicles also traditionally have mixed performance on softer ground, such as sandy beaches, to begin with.

The U.S. Army has already experienced similar issues over the years with its Stryker 8x8 wheeled vehicles as they have received additional weapons and armor. Extra weight and bulk could limit the ACV 1.1's ability to maneuver in dense urban areas and cross gaps using existing civilian bridges once they get ashore, too.

Any added systems, especially remote weapon stations or manned turrets, could also impact the total number of Marines each ACV 1.1 can carry at a time. In addition, the Corps says it is only now investigating a “lethality upgrade” as part of the ACV 1.2 increment, but the limitations of the base SuperAV chassis will now be a primary factor in determining any future weaponry requirements.

Furthermore, unlike the AAVs, which shares engine and chassis components with the Army's Bradleys, the ACV 1.1s have no clear commonality with any existing systems. This could make them more difficult and expensive to operate and sustain in the long term.

More importantly, the need for a higher speed vehicle more capable of operating in the open ocean to allow amphibious ships to stage further away from enemy defenses hasn’t gone away. That concerns that led to the EFV program have only become more pronounced, especially given China’s continued militarization of the South China Sea and deployment of longer-range anti-ship and anti-aircraft systems on its man-made outposts in that region.
What it’s left with at the moment is a wheeled vehicle that is faster and has better underbody protection than the older tracked types, but is also slower in the water, has a far more limited payload capacity, and a significantly higher price tag. And since the Marines do not plan to purchase enough ACVs to replace all of the AAVs at present, the two vehicles will be expected to work together for the foreseeable future anyway.

All told, it appears that the ACV 1.1s could be an important supplement to or substitute for the AAVs in certain situations, but whether they’ll ever be able to actually replace the existing vehicles completely remains to be seen. ... y-have-now

Der Autor war sich wohl nicht bewusst, dass die aktuelle Variante des AAV keine 28 Personen (3+25) mehr transportieren kann:

PM Advanced Amphibious Assault
Programmed for eventual replacement by a new Amphibious Combat Vehicle (ACV), the AAV7A1 RAM/RS FoV will continue to serve the Marine Corps until at least 2035. It is perhaps noteworthy that the new 2035 lifespan projection for the FoV is 10 years longer than service projections made as little as one year ago.

The AAV Survivability Upgrade Program, which will affect 392 of the Personnel variants, will further improve force projection while maintaining the current land and water mobility of the AAV, serving as a capability bridge to fielding and replacement by the new ACV. The 392 platforms included in the AAV Survivability Upgrade will provide the Marine Corps operational forces with four battalions of lift plus some additional support capabilities.

The Survivability Upgrade initiative will improve force protection and platform survivability by integrating technically mature upgrades into the existing hull. These upgrades include belly and sponson armor, blast-mitigating seats, and spall liners. The upgrades may also include fuel tank protection, and automotive and suspension upgrades to maintain current land and water mobility characteristics despite increased weight growth.
The redesign will take the vehicle from approximately 21 bench seat spaces to 17 blast-mitigating seats. ... n_12-2.pdf

Wenn für das AAV eine höhere Geschwindigkeit im Wasser gefordert worden wäre, hätte man eine komplette Neuentwicklung gebraucht. Mit allen damit verbundenen Risiken. Und keiner der Kandidaten aus dem aktuellen Wettbewerb hätte zum Zug kommen können.

Armour-maker Armatec slashes workforce as defence sector takes hit (6. September 2018)
London’s defence sector has suffered another blow as armour-maker Armatec has slashed up to 50 workers at its Dorchester plant.

The manufacturer lost a contract with a supplier to the U.S. Marines, providing armour kits for a fleet of amphibious vehicles, forcing the layoff of about half its workforce Tuesday.

General Dynamics Land Systems Canada, the armoured vehicle manufacturer in London, also announced 28 layoffs this week.
Armatec supplied Science Applications International Corp. (SAIC) in Virginia with armour kits to be applied to the Marine Corps’ assault amphibious vehicle (AAV) personnel carrier.

The Marines cancelled that order as it has decided to stop re-armouring older vehicles and focus instead on buying new, replacement ones, called the amphibious combat vehicle (ACV), said Manny Pacheco, spokesperson for Marine Corps land systems in Virginia.

“We have decided to cancel that program. We decided to focus on modernizing rather than investing in legacy systems,” said Pacheco. “The ACV has performed much better.”

“The decision had nothing to do with the armour or the vehicle, but it was strategic. We want to focus on modernization and this is a 40-year-old system.” ... -workforce

CONFIRMED! SAIC got a stop work order from the govt on the AAV-SU! (28. August 2018)

What does this mean?

I'm really not sure. Could they be forgoing the upgrade to buy more ACVs? Could this be a problem with SAIC executing on the AAV-SU program?

Not sure.

What I do know is that this is a savage body blow to SAIC. Their attempt to enter the armored vehicle market might be forever doomed with this news. ... -from.html

Noch im Juni war die Rede davon, das AAV bis 2035 (!) weiter zu betreiben und teilweise über FMS an ausländische Nutzer zu verkaufen:

U.S. Marine Corps orders more Amphibious Combat Vehicles
BAE Systems has received a $120 million contract from the U.S. Marine Corps for additional Amphibious Combat Vehicles under a third order for Low Rate Initial Production (LRIP).

This award is an important next step on the path to full rate production. This latest contract is for the ACV personnel carrier variant (ACV-P), an eight-wheeled amphibious assault vehicle capable of transporting Marines from open-ocean ship to shore and conducting land operations. Each vehicle embarks 13 Marines in addition to a crew of three.
Current low-rate production is focused on the ACV-P variant. More variants will be added under full rate production to include the command and control (ACV-C), 30mm medium caliber turret (ACV-30) and recovery variants (ACV-R) under the ACV Family of Vehicles program. BAE Systems previously received the Lot 1 and Lot 2 awards.
ACV production and support is taking place at BAE Systems locations in Stafford, Virginia; San Jose, California; Sterling Heights, Michigan; Aiken, South Carolina; and York, Pennsylvania. ... ae-systems
