JLTV - Capability Without Compromise

Capability Without Compromise

Driving along a dirt road in Afghanistan, soldiers aren’t just worried about taking the shortest route from point A to point B. They are worried about their safety and the possible roadside bombs or improvised explosive devises (IEDs) that may lie in their path. For these soldiers, protection is a must, and their vehicle could be the difference between life and death.

The emerging IED threat became apparent in Iraq and Afghanistan, demanding an immediate solution. To protect soldiers, the Army quickly up-armored many of their Humvees and purchased thousands of mine-resistant, ambush-protected vehicles (MRAPs). But the increase in protection had a downside: Heavier vehicles with severely compromised off-road performance that were more difficult to transport.

Lockheed Martin’s Joint Light Tactical Vehicle meets the IED problem head-on, returning crucial mobility and protection to Soldiers and Marines by creating a common family of vehicles that effectively balances payload, protection and performance.

Designed from the ground up to be a combat vehicle and supplement or replace the existing fleet of Army and Marine Corps Humvees, the Lockheed Martin JLTV offers outstanding overall capability while remaining affordable.

The Team

Formed in 2005, the Lockheed Martin JLTV team draws from more than three decades of experience in vehicle concept design, development, production and sustainment across a range of products, from manned to unmanned ground systems. Lockheed Martin’s vehicles are the bridge between rugged and high-tech, offering proven and intelligent capabilities for the end user.

The vehicle’s capabilities include:

  • Lockheed Martin is the prime contractor and design agent, providing systems engineering, platform integration, design expertise, and program and supply chain management.

  • BAE Systems brings its expertise in advanced armor solutions and high-volume manufacturing, along with years of experience delivering battle-proven systems.

  • Tier 1 Suppliers include Allison Transmission, Cummins Engine, L-3 Combat Propulsion Systems, Meritor Defense, Robert Bosch LLC and Vehma International of America.

The Innovations

The Technology and Development (TD) phase helped the U.S. military to identify possible risks and establish a set of requirements prior to entering the Engineering Manufacturing Development (EMD) Phase of the JLTV program. After the TD phase, the Lockheed Martin team optimized its design for EMD, creating a lighter, stronger and more efficient vehicle system through the use of digital engineering analysis, virtual design builds, component tests and physical stress testing. Team member BAE systems also brought their expertise in high-volume assembly to help develop the production process verified by the virtual design build.

Through rigorous testing and ongoing improvement, Lockheed Martin is delivering the best JLTV solution to protect the men and women who go into harm’s way to defend our freedom.

The vehicle’s capabilities include:

  • Crew Protection: Government tests in the program’s Technology Demonstration phase showed the Lockheed Martin JLTV exceeds threshold requirements for force protection in blast tests, and provides protection levels similar to much heavier and less mobile Mine Resistant Ambush Protected (MRAP) vehicles.

  • Best Value: The JLTV provides the most capability while staying within the program’s target cost with room for sufficient margin. Superior fuel efficiency, high reliability, and low logistical support costs reduce the total lifecycle cost of the vehicle.

  • Fuel Efficiency: A proven power train comprising a Cummins turbodiesel engine and Allison transmission contribute to tremendous improvements in fuel efficiency and reduced operating costs compared to existing general-purpose vehicles.

  • Transportability: With a focus on remaining light, the Lockheed Martin team removed more than 40 percent of its original weight. The JLTV is light enough for CH-47 and CH-53 lift.

  • Power Generation: The Lockheed Martin team's JLTV power is scalable to ~75kW, which significantly exceeds the Government’s required minimum power generation of 10 kilowatts.
  • Ride Quality: The JLTV covers more ground faster, and with less road shock and vibration for greatly improved crew comfort, protection of vital electronics systems, and high speed driving in off-road conditions.

  • Suspension System: The Meritor ProTecTM adjustable air suspension underpinning the Lockheed Martin JLTV provides significant enhancements to handling and ride quality, decreasing fatigue and increasing the crew’s combat effectiveness, and enabling multiple transport options.
