“Rather than following a traditional TD test program, the JLTV program has adopted a more comprehensive approach. The JLTV approach will enable the services to gauge technical potential against JLTV key perfor- mance parameters, placing emphasis on modeling and simulation, systems component testing, risk reduction, and increased readiness for the Engineering and Manufacturing Development [EMD] phase,” added LTC Wolfgang Petermann, the Army’s Product Manager JLTV.
The expanded JLTV TD will include more emphasis on system evaluation, system performance testing (rather than component testing), reliability testing, ballistic testing (coupons, ballistic hulls, prototypes), limited transportabil- ity demonstrations using operational assets, and early warfighter evaluations.
Vehicles will undergo performance and ballistic testing at APG and reliabil- ity and maintainability testing at YPG. Once performance testing is complete on JLTV Category A, B, and C vehicles at APG, the vehicles will be subjected to a limited user test with Soldiers and Marines, running the vehicles through a series of vignettes and soliciting feed- back from the user jury. Both JLTV Category A and B vehicles with full
JLTV has taken the traditional TD phase testing and expanded it to focus more on system-level testing rather than the traditional component-level testing.
B-kit configurations will run at YPG for the entire test duration.
The Australian vehicles are scheduled for delivery during June–July 2010 and will concurrently undergo test- ing with the U.S. vehicles, enhancing global interoperability between the U.S. and Australian forces. The Australian vehicles feature right-hand operation; commonality with the left-hand opera- tion vehicles is around 95 percent for all three TD contractors. Different design approaches among the three TD contractors have shown no weight increase for one contractor, as they have only modified existing parts with- out adding parts. The two other TD contractors have added parts, which resulted in a 20-pound weight increase for one contractor and a 40-pound weight increase for the other.
JLTV TD contractors will also deliver one ballistic hull and vehicle proto- type with enhanced protection, called JLTV-A Enhanced Protection (EP),
during the TD phase. This vehicle modification will increase the inher- ent protection requirements originally required for the JLTV Category A General Purpose vehicle by improv- ing its side and underbody protection capabilities. The Essential Combat Configuration weight requirement for the JLTV-A EP modification is 15,300 pounds. The government will take delivery of the JLTV-A EP vehicle in October 2010.
Rebalancing the Future of the LTV Fleet
Developing the JLTV reinforces the Army’s approach to interoperable plat- forms that provide expeditionary and protected maneuver to forces currently supported by high-mobility multi- purpose wheeled vehicles. The intent of the JLTV is to facilitate brigade combat teams’ (BCTs’) symmetric and asymmetric approaches to tactical and operational maneuvers by improving their versatility and agility. The JLTVs also improve payload efficiency through chassis engineering, enabling the vehi- cles to be deployed with the appropriate amount of force protection through scalable armor solutions.

The capability gaps within the existing light tactical wheeled vehicle fleet are the result of an imbalance in protec- tion, payload, and performance. The JLTV Family of Vehicles (FOV) will be able to deliver all of these capabilities within a transportable and expedition- ary vehicle, meeting the Army and USMC rotary- and fixed-wing air, sea, and overland transport require- ments—something no existing light tactical wheeled vehicle can do. “The JLTV FOV is expected to achieve
