U.S. Army Chief Of Staff Wants Lighter GCV

The U.S. Army’s chief of staff wants to put the service’s Ground Combat Vehicle program on a diet.
Gen. George Casey said he thinks the future replacement for the Bradley
Fighting Vehicle needs to be much lighter than the estimated 70 tons
program officials are projecting that the new GCV will weigh.
“I keep saying, ‘Look, man, an MRAP [mine-resistant ambush-protected] is about 23 tons, and you’re telling me this is going to be 70 tons,
which is the same as an [M1] Abrams. Surely we can get a level of
protection between that, that is closer to the MRAP than it is the M1,’
” Casey said June 7. “It’s not going to be a superheavyweight vehicle.”

Casey’s comments come less than a month after Army Vice Chief of
Staff Gen. Peter Chiarelli said at the Armor Conference at Fort Knox,
Ky., that the GCV would weigh 50 to 70 tons.
Critics point out
that a 70-ton GCV would be the world’s heaviest infantry fighting
vehicle. By contrast, the heaviest vehicle for the Marine Corps is the
Expeditionary Fighting Vehicle, an amphibious armored personnel
carrier. Still in development, it is expected to weigh 38 tons.
The Bradley can weigh up to 36 tons.
firms submitted their proposals for the first phase of the GCV in late
May. Program officials expect to award up to three contracts for the
technology development phase in September.
The Army launched
the GCV program in April 2009 as part of a larger Army Brigade Combat
Team Modernization program, formerly known as Future Combat Systems.
effort stood up quickly after a decision by Defense Secretary Robert
Gates to kill the Manned Ground Vehicles portion of the Army’s FCS
program in the fiscal 2010 defense budget. Gates spared the high-tech
communications network and the spin-out technologies slated for
fielding in 2011, but canceled the program’s family of 27-ton MGVs,
criticizing the design as ill-suited to survive current battlefield
The Army wants the GCV to have the underbelly armor of
the MRAP, better side protection than the Bradley, some type of
automatic cannon and an anti-tank missile system.
The V-shaped
hull on the MRAP allows the vehicle to withstand blasts from roadside
bombs and protect soldiers inside. The Bradley has side armor that can
stop 20mm and other potent calibers. Newer Stryker vehicles can stop
14.5mm projectiles.
Officials want the GCV to perform well in open country, on roads and in urban areas.
officials stress the importance of the GCV since the service continues
to rely on its fleet of 16,000 combat vehicles on a battlefield
dominated by powerful improvised explosive devices.
“The Ground
Combat Vehicle is going to be the first vehicle designed to operate in
the environments that we’re operating in today, particularly in IED
environments,” Casey said. “None of the vehicles that we have now,
except possibly the MRAPs, are designed for that. … With the Bradley
and the tank, they started back in the late 60s and early 70s, and they
have been great, but as we built out the Bradley, it’s at the limits of
size, weight and power.”
The Bradley can carry up to seven infantrymen in addition to a commander, gunner and driver.
GCV is being designed to carry a complete nine-man infantry squad and a
three-man crew and provide them with MRAP-like protection – that’s at
least 50 tons using today’s technology, Chiarelli said at the Armor
But Casey said that soldiers who have served in Iraq
and Afghanistan have told him that big, heavy vehicles just aren’t
practical in urban combat.
“They’ll tell you, we stopped using
tanks and Bradleys on the streets of Baghdad just because of the size,”
Casey said. “We have to work the tradeoffs between protection and size.”
for wheels or tracks, the Army did not specify in its request for
proposals, but Chiarelli and other senior Army officials have said the
GCV would likely have to be tracked based on the current weight
For now, the plan is to ensure that the new vehicle
can be transported by C-17 aircraft, rail and ship. An Army “analysis
of alternatives” will attempt to provide some type of recommendation
sometime this summer.
It is unusual for an analysis of
alternatives to be done in parallel with the request for proposals
process, but Army officials have said it’s being done that way to save
Army officials have said the five- to seven-year
development timeline is in place to follow Pentagon acquisition-reform
guidelines that call for more testing and competitive prototypes. The
decision to build a new vehicle or buy a current design will be up to
the Defense Department.
Casey said the Army has the time to
work through these issues. The service aims to have a prototype in hand
by 2015, and field the new infantry fighting vehicle in 2017.
“We’re at the beginning of the process,” Casey said. “This thing is going to take about seven years to get on the street.”
