Procurement officials also pointed out that there were
many different models of wheeled combat personnel
carriers, some with amphibious capabilities, operating
around the world, which could be acquired faster and at
lower cost than developing a new tracked vehicle. The
Request for Proposals (RfP) specified the offerings had
to be based on vehicles currently in production.
The RfP drew five strong offerings, from which
Land Systems selected BAE’s and SAIC’s, both of which
were eight-wheeled vehicles in service with partner
nations. On Nov. 24, 2015, the Marines awarded BAE
$103.7 million and SAIC $121.5 million to produce and
support the test vehicles during the ACV’s engineering,
manufacturing and development phase.
SAIC’s ACV is based on the TERREX II produced by
ST Kinetics in Singapore and in service with its security
forces. It has been upgraded and modified to meet the
Marines’ requirement. Company officials said their ACV
can carry a crew of three and 11 combat-loaded Marines.
Powered by a 625-horsepower Caterpillar diesel
engine, it can travel at 7 mph in the water and at least 55
mph on land. It offers a “V-over-V” hull design to deflect
the effect of IEDs, underbody armor and blast-mitigating
seats to help shield troops from the explosive force.
BAE’s ACV is derived from the SUPERAV 8x8, produced by Iveco Defense System of Italy and in use by
several nations. It can carry a crew of three and 13
Marines, which is a normal rifle squad. With a 690-
horsepower Cummins diesel engine, the company says
it can swim at 6 mph and hit 70 on land.
The vehicle has no axles, which BAE says allows it
to have additional ground clearance and a “V”-shaped
hull to mitigate IED effect. It also has composite armor
and shock-absorbing seats.
To meet Marine requirements, both vehicles have
a Remote Weapon System on top with a .50-caliber
machine gun and 40mm grenade launchers.
Both companies have amphibious vehicle experience.
BAE built the original AAVs and SAIC has the current
Survivability and Upgrade contract to substantially
improve and extend the life of 392 AAVs, which are
expected to augment the ACVs when the new vehicles
enter service in 2020. The remaining AAVs either will
continue operating with earlier upgrades or be retired
as ACVs become operational.
The Marines call the first group of vehicles ACV 1. 1,
which initially were not expected to be truly amphibi-
ous, with the ability to go on and off amphibious ships.
But Col. Kirk Mullins, ACV 1. 1 program manager, said
both contractors have shown their vehicles have that
capability, “so were going to test that.”
The contractors are required to put their vehicles
through a break-in and test process, with 500 miles of
land mobility trials over varied terrain and five hours
in the water, before presenting them to the Marines for
a functional test, physical inspection and acceptance,
The Science Applications International Corp. (SAIC) team unveiled its first Amphibious Combat Vehicle (ACV) 1. 1 prototype Feb. 21. Its prototype
is based on the TERREX II produced by ST Kinetics in Singapore and can carry a crew of three and 11 combat-loaded Marines.
