The Joint Light Tactical Vehicle (JLTV) is a United States military (specifically U.S. Army, USSOCOM, and U.S. Marine Corps) program to replace the Humvee that is currently in service[1] with a family of more survivable vehicles with greater payload. In particular, the Humvee was not designed to be an armored combat and scout vehicle but has been employed as one, whereas the JLTV will be designed from the ground up for this role. Production is planned for 2015. The U.S. Army planned to buy 60,000 and the U.S. Marine Corps planned for 5,500 vehicles in 2010.[2]

The JLTV program is related to, but not the same as, the Future Tactical Truck Systems (FTTS) program. Lessons learned from the FTTS have been fed into the JLTV requirements. The future family of vehicles will comprise five armored versions, ranging from light armored vehicle, infantry fighting vehicles, command post vehicles, reconnaissance vehicles, and armored utility vehicles.

There will probably also be an armored personnel carrier and a number of other non-armored versions for other purposes such as ambulances, utility vehicles and general purpose mobility. Such a design could also be used in place of an armored personnel carrier or unarmored trucks. However, the JLTV program was in danger of being outpaced by the rapid development of lightweight MRAPs.[3]

It appeared the U.S. Army had reduced its support for the program, since JLTV numbers were omitted from its tactical vehicle strategy published in June 2010.[4][5] However, the U.S. Army clarified that JLTVs are slated to both replace and complement the Humvee.[5][6] On 5 January 2012, TACOM announced that the program had entered the Engineering and Manufacturing Development (EMD) phase;[7] EMD contracts were awarded on 23 August 2012. Planned orders are now 50,000 vehicles for the U.S. Army and 5,000 for the Marines.[8]

History [edit]

The following companies and partnerships initially bid for the JLTV contract:

On 29 October 2008, the Pentagon narrowed the field of vendors to the Lockheed Martin, General Tactical Vehicles and BAE Systems/Navistar teams to compete for the final version and contract for the JLTV. Each team received contracts worth between $35.9 million and $45 million to begin the second phase of the program, which could ultimately be worth $20 billion or more.[20] On 17 February 2009, the Government Accounting Office denied the protests.[21]

Australia signed an agreement in February 2009 to fund nine of the first 30 JLTV prototypes.[22] While a final decision has yet to be made, the Australian Government is now pursuing a domestically developed vehicle through Thales-Australia[23] India became interested in the program in 2009.[24]

As part of a cost-cutting measure, the National Commission on Fiscal Responsibility and Reform suggested canceling the JLTV.[25] Despite this, the program moved forward. On 24 January 2012, the Humvee Recap program was canceled for funding to be moved to the JLTV.[26]

As of 28 March 2012, there were 6 proposals for the JLTV contract:[27]

EMD contracts [edit]

On 23 August 2012, the Army and Marine Corps selected the Lockheed Martin JLTV, the Oshkosh Defense L-ATV, and the AM General BRV-O as the winners of the Engineering and Manufacturing Development (EMD) phase of the competition. The three companies were awarded a contract to build 22 prototype vehicles in 27 months to be judged by the services.[8] Losing bidder Navistar filed a protest with the Government Accountability Office (GAO) over the evaluation criteria on 31 August 2012.[31] The company withdrew the protest on 4 September 2012.[32]

The Lockheed JLTV family underwent a design understanding review from December 18–20, 2012. The government design review assessed all elements of the design and confirmed its overall maturity and requirements compliance. Lockheed used a production-enhanced model, which is lighter and cheaper than the earlier technology demonstration model. By then, the Lockheed JLTV design had over 160,000 combined testing miles. Vehicles produced for the EMD phase of the program are due to begin deliveries in spring 2013.[33]

On 14 February 2013, Oshkosh unveiled the utility variant of their L-ATV (Light Combat Tactical All-Terrain Vehicle) for the program. The utility variant fulfills the JLTV requirement for a two-seat cargo vehicle, while the L-ATV base variant meets the requirement for a 4-seat multipurpose vehicle. In addition to hauling cargo, it can be outfitted as a shelter carrier to carry standard shelters for communications systems, on-board electronics, and other functions. The utility vehicle has two crewmen and has a 5,100 lb payload.[34]

Design requirements [edit]

In 2006, Joint Light Tactical Vehicle design requirements included the following.

The JLTV will have two armor kits: the A-kit and a B-kit (which adds additional protection to the A-kit).[35][36] It will also include an extra spall liner to minimize the perforation effects within a vehicle when the vehicle takes hostile fire.[35][37]

The vehicle will be capable of traveling one terrain feature after having endured a single small caliber arms sized perforation to the fuel tank, engine oil reservoir, or coolant system.[35] It will be able to run on two flat tires.[35][37]

The USMC requires a vehicle that can be transported by their current and planned systems. In April 2009, Marine Corps Commandant Gen. James Conway warned that the Marines “will not buy a vehicle that’s 20,000 lb.”[38]

The vehicle's jam-resistant doors will allow the passengers to easily escape after the vehicle has taken damage.[35][37] It will include an automatic fire extinguishing system,[37]

The JLTV will be equipped with a diagnostic monitoring system that will electronically alert the operator of equipment failures so that they can be fixed. The electronic monitoring will observe the fuel, air intake, engine, cooling, transmission, energy storage, power generation and vehicle speed as well as other systems.[35][37]

The JLTV will have a trailer capable of carrying the same payload as its prime mover over the same speeds and mission profile.[35] It will have the capacity to carry various kinds of ammunition.[35]

Mobility [edit]

Logistical mobility [edit]

JLTV is transportable by sea, rail, and air. The JLTV will be transportable on all classes of ocean-going transport ships with minimal dis-assembly. It is required to be rail-transportable on CONUS and NATO country railways. Air transportability will be by fixed-wing aircraft as large as or larger than the C-130 Hercules and sling-loadable with rotary-wing aircraft such as the CH-47/MH-47, and CH-53. The ambulance variant must be air-dropable by C-5 and C-17 fixed-wing aircraft.[39]

Countermeasures and Survivability [edit]

The JLTV utilizes signature reduction techniques and materials. The JLTV mounts up to four M7 Light Vehicle Obscuration Smoke Systems. The JLTV is designed with a base structure called an A-structure and B-kit armor that provides higher protection levels. JLTV also incorporate various additional survivability technologies to meet requirements.The JLTV is designed to accept transparent window armor. To prevent casualties due to fires, the fuel tanks are mounted outside the crew compartment and are required to be self-sealing. Fires in the engine compartment are to be detected and extinguished within 10 seconds to minimize vehicle damage. In addition, the driver also has access to a small portable fire extinguisher.[39]

Versions [edit]

JLTV configurations

There are three primary variants of the JLTV, which are categorized by their payload and general mission, and within that category, further variations may exist for specific purposes. All vehicles share some capabilities, while certain configurations may have additional capabilities. All variants are transportable externally by CH-47 and CH-53 helicopters and internally by C-130 aircraft.[40]
