Lockheed Martin developed its first JLTV Combat Tactical
Vehicle prototype in 2007. The next year the company successfully competed for the JLTV Technology Demonstration
contract, which it used to continue developing the technology.
In 2014, after successfully completing the U.S.
Government’s Production Readiness Review (PRR), in which
they demonstrated assembly, integration, and production
capabilities, Lockheed Martin submitted their production proposal.
Joining Lockheed Martin, however, is AM General LLC (who
builds the current Humvee) and Oshkosh Defense, the two
other companies vying for the contract to produce the next

The Lockheed Martin JLTV Team is made up of various
companies with decades of military vehicle production experience, including production partner BAE Systems, which is
responsible for the JLTV’s occupant-centric protection system.
Additionally, the vehicle is equipped with an independent air bag suspension from Meritor, and a unique scalable power generation/exportable power solution from L- 3
Communications. The 4.5-liter, 4-cylinder engine is provided
by Cummins, and an Allison six-speed transmission completes the drive train.
Even with this impressive lineup of partners, the design
process began with a simple blank sheet of paper, as the
vehicle was designed from the ground up to meet the JLTV’s
“Our design and prototyping efforts were extensive, as we
knew we had to design in not only new technologies, but
also allow for growth and expansion in the future,” explains
Kathryn Hasse, Lockheed Martin JLTV program director.
From day one, sustainability was one of the key consid-
erations in the JLTV’s design. “We realized early on
that we had to design and produce a vehicle that was
sustainable over decades, so we designed in modu-
larity and expandability in every possible aspect of
the vehicle,” says Hasse.
To facilitate a smooth design process, the team
applied robust systems engineering and lean
manufacturing techniques to the entire design
and production chain. Hasse explains that the
processes were even applied down to the indi-
vidual component manufacturers to ensure
that all of the parts could handle the rigors
of a military grade vehicle. Various software
tools were also used for simulation and model-
ing purposes prior to drawing generation. The
production system for the factory layout and the
production processes were also modeled.
REPLACING THE HUMVEE
After 25 years, the U.S. Army and Marine Corps are upgrading the iconic Humvee.
Lockheed Martin began its foray into the tactical wheeled vehicle market in
2004. Two years later, after
purchasing HMT vehicles LTD,
Lockheed Martin was awarded
a contract for the Army
Future Tactical Truck System
Army Concept Technology
Demonstration (ACTD). The
JLTC program was born soon
after when the U.S. Congress
directed the U.S. Army and
Marine Corps to replace the High
Mobility Multipurpose Wheeled
Vehicle (HMMWV) – the vehicle
commonly known as the Humvee
– which has been in use since
