The Oshkosh L-ATV (Light Combat Tactical All-Terrain Vehicle) is a light utility/combat multi-role vehicle that won the US military's Army-led Joint Light Tactical Vehicle (JLTV) program. In the very early stages of the program it was suggested that JLTV would replace the AM General High Mobility Multi-purpose Wheeled Vehicle (HMMWV) on a one-for-one basis. It is now suggested that the JLTV will part-replace the HMMWV, not replacing it on a like-for-like basis.

Oshkosh's L-ATV will deliver a level of protection similar to that of current, but far heavier and less maneuverable, Mine Resistant Ambush Protected (MRAP) class designs, these having far more protection from blast than even the latest up-armored HMMWVs.

On 25 August 2015, the L-ATV was selected as the winner of the JLTV program. The first JLTV delivery order was placed in March 2016 with the U.S. Army ordering 657 trucks. Overall JLTV requirements are 9,091 vehicles for the Marine Corps with all to be delivered in FY 2022, and 49,099 for the Army entering service in late 2019 with deliveries occurring through 2040. The Air Force and Navy will also receive small quantities of JLTV, and all totals are subject to change. The Army received its first seven JLTVs for test at the end of September 2016, Colonel Shane Fullmer, JLTV project manager stated at an AUSA 2016 media briefing.

The idea for the Joint Light Tactical Vehicle (JLTV) first emerged in 2006 from threats experienced during the Iraq War. The primary tactical wheeled vehicle used by the U.S. military at the start of the war was the Humvee. However, it was unarmored and built for payload mobility, so the type incurred heavy losses when improvised explosive devices (IEDs) began being employed by insurgents. The initial response was to add armor to existing Humvees, and primarily on the sides. This improved side protection against direct fire and associated threats, but since the chassis was not designed to handle any further additional weight, there was little room for underbody protection. The additional weight impacted on overall reliability and compromised off-road mobility.


To combat increasing numbers of IED attacks, the U.S. spent around $50 billion rapidly procuring some 29,000 Mine Resistant Ambush Protected (MRAP) vehicles, including the Oshkosh M-ATV for use in Iraq and Afghanistan. While MRAPs offered superior protection from IEDs, especially underbody blasts, they were significantly larger and heavier and had relatively poor off-road mobility. The military incorporated MRAPs in response to operational needs, but never intended them to become a permanent part of their tactical wheeled vehicle fleets. At the conclusion of operations, many thousands were either scrapped, adapted for other roles, or offered for sale/transfer to allies. Ultimately U.S. armed forces would retain over 11,100 MRAPS, just over 6,350 of these Oshkosh M-ATVs. The bulk of retained MRAPS are mothballed in prepositioned stocks around the world.

Since up-armoring Humvees and buying MRAPs addressed specific issues but created gaps in vehicle capabilities, the JLTV program was started to incorporate lessons learned and balance payload, mobility, and protection into a new vehicle. Its purpose was to restore the mobility commanders had with the original Humvee, while having the side and underbody protection of a basic MRAP. It would be around two-thirds the weight of an MRAP, possible to be carried under a CH-47 Chinook and CH-53E Super Stallion and by amphibious vessels, things impossible for an MRAP. It would also be 70 percent faster off-road, adding to survivability by enabling it to egress a combat situation faster. Compared to the Humvee, the JLTV was to have the mobility of early unarmored versions with greater protection than up-armored versions, along with greater reliability, payload capacity, and ease of repair. The JLTV is the first vehicle purpose-built for network connectivity into the Warfighter Information Network-Tactical.

Oshkosh Defense first displayed the L-ATV at Association of the United States Army (AUSA) in Washington, D.C. on 10 October to 12 October 2011. This, the first 'public appearance' for the design, was not an open appearance and came in the form of closed combined briefings/viewings to invited attendees only. Oshkosh briefed Jane's Independent Defense Review that the L-ATV has developmental origins that trace back to 2007 and Oshkosh/Northrop-Grumman's failed JLTV proposal, with some sub-systems having a lineage that trace back to 2005. At the time, L-ATV was the lightest tactical vehicle designed by Oshkosh, being some 50% lighter than anything previously produced by the company.

At AUSA 2011, Oshkosh suggested that following then recent program developments, L-ATV would be offered to meet the recently revitalized JLTV's EMD (Engineering and Manufacturing Development) phase. On 26 January 2012, the RFP for JLTV's EMD Phase was released. On 23 August 2012, the Army and Marine Corps selected the Oshkosh Defense L-ATV, as well as the Lockheed Martin JLTV entry and AM General BRV-O, as the winners of the Engineering and Manufacturing Development (EMD) phase of the JLTV competition. They were awarded a contract to build 22 prototype vehicles in 27 months to be judged by the services.

On 6 February 2013, Oshkosh unveiled the Utility Variant of its JLTV offer, fulfilling JLTV's requirement for a two-seat cargo vehicle. The vehicle's performance was demonstrated at the 2013 NATC Technology Rodeo at the Nevada Automotive Test Center (NATC). The Utility Variant is designed to provide mobility for loads such as containers, pallets, and break bulk cargo. It can also be outfitted as a shelter carrier to carry standard shelters for communications systems, on-board electronics, and other functions. Payload capacity is in excess of 5,100 pounds. Both Oshkosh L-ATV variants leverage a common crew protection system, automotive systems, and the patented Oshkosh TAK-4i™ intelligent independent suspension system.

In June 2013, L-ATV prototypes participated in an event hosted by the U.S. JLTV Joint Program Office in Quantico, VA. The vehicles successfully completed the severe off-road track (SORT) without failure. The SORT demonstrated the L-ATV's ability to maneuver steep inclines, turn sharply, and operate in rugged terrain. On 8 August 2013, Oshkosh delivered its first L-ATV JLTV prototype to the Army for government testing following a successful vehicle inspection by the Defense Contract Management Agency (DCMA). The four-door variant (which has two base platforms – Close Combat Weapons Carrier (CCWC) and the General Purpose (GP)) and two-door Utility Variant were provided for evaluations.

On 27 August 2013, the Army and Marine Corps announced that full-scale testing of JLTV prototypes would begin the following week, with all three vendors having had 66 vehicles delivered. Each company delivered 22 vehicles and six trailers to Aberdeen Proving Ground, Maryland, and Yuma Proving Ground, Arizona. Previous testing had already put the vehicles through more than 400 ballistic and blast tests on armor testing samples, underbody blast testing, and more than 1,000 miles in shakedown testing. Soldiers from the Army Test and Evaluation Command and personnel from the Defense Department's Office of Test and Evaluation would begin to put the vehicles through realistic and rigorous field testing during 14 months of government performance testing. Testing was scheduled for completion by FY 2015, with a production contract to be awarded to a single vendor for almost 55,000 vehicles (49,099 Army; 5,500 Marines). The average unit manufacturing cost in A-kit (fitted for but not with armor) configuration was not to exceed $250,000. The Army set an Initial Operating Capability (IOC) of May 2018 and planned to complete its fielding by FY2040. The Marines had an IOC of December 2017, and planned to complete its fielding by FY2022. On 3 September 2013, full-pace, full-scope JLTV testing began at Aberdeen Proving Ground, Yuma, and Redstone Arsenal, Alabama. One vendor was to be selected by July 2015, and produce 2,000 vehicles for three years of additional testing to fine-tune the assembly line and full-up the system.

In July 2014, the L-ATV completed Net-Ready testing as part of the JLTV program, involving transferring data from onboard systems to external networks. On 17 July 2014, Oshkosh announced the L-ATV had completed 200,000 miles and all requirements for Reliability, Availability, Maintainability (RAM) testing. On 19 November 2014, Oshkosh announced the L-ATV had completed Limited User Testing (LUT) with the U.S. Army and Marine Corps for the JLTV EMD contract. The LUT focused on JLTV system capabilities, functions, operations, and interfaces in a range of simulated tactical environments covering operator and crew-level preventive maintenance for the entire system, ensuring they could operate proficiently and safely. The Army held theirs the previous September and October, where three tests were held as 96-hour cycles to simulate operational missions, one of which incorporated a live fire demonstration. The Marines completed two test cycles in October and November with one live fire demonstration. The Army released the final JLTV RFP on 12 December 2014. On 10 February 2015 Oshkosh Defense issued a press release announcing the company had submitted its proposal (the L-ATV) in response to the JLTV Low Rate Initial Production (LRIP) and Full Rate Production (FRP) RFP.

On 31 March 2015, Oshkosh announced it would show its JLTV offering, the L-ATV, at the AUSA 2015 Global Force Symposium and Exposition in Huntsville, Alabama. The company also announced it would show its Virtual Task Trainer (VTT) for the L-ATV at the conference. The VTT is an interactive training module that provides interactive 3D training for soldiers in a safe and lifelike virtual environment. Speaking of the VTT, Mike Ivy, vice president of global integrated product support for Oshkosh Defense said: "The addition of Oshkosh's virtual training to our multi-faceted curriculum reduces the cost of operator training by improving training effectiveness and efficiency." He added: "We deployed the VTT to train operators during early JLTV testing with great results. Soldiers were really engaged, and our training was not only better, but it took less time than it would have without the VTT. This represents a significant cost savings opportunity for the government."

On 25 August 2015, the Army selected the Oshkosh L-ATV as the winner of the JLTV program. The company was awarded a $6.75 billion low rate initial base contract with eight option years to procure the first 16,901 vehicles for both the Army and Marines. Oshkosh CEO, Charles Szews, said the production contract award would involve more than 300 suppliers in 31 states across the country. The Army initially refused to detail why the L-ATV was chosen over its competitors, likely owing to anticipations of protests from the losing bidders.

On 8 September it was disclosed that Lockheed Martin would protest the award to Oshkosh; on the same day it was also disclosed that AM General had decided not to file a protest. Any work that would be performed under the contract stopped during the review period. On December 15 the Government Accountability Office (GAO) dismissed Lockheed Martin's protest because the company on December 11 decided to file a “Notice of Post-Award Bid Protest” with the U.S. Court of Federal Claims; according to a source with knowledge of the procedures, it is uncommon for a company to file with the court close to a GAO protest decision. Immediately after the GAO dismissed the protest, the Army instructed Oshkosh to resume work on the JLTV order. Lockheed filed their preliminary injunction on 17 December, claiming that new Army-supplied information related to the contract emerged toward the end of the GAO’s protest process that was not considered before their ruling and no deadline extension was granted. On 17 February 2016, Lockheed withdrew their protest of the JLTV contract award decision in the Court of Federal Claims, potentially as a result of the release of JLTV testing data showing that the L-ATV lasted nearly six times longer between significant breakdown than Lockheed's vehicle.

The first JLTV order was announced on 23 March 2016 with the U.S. Army ordering 657 JLTVs. The $243 million order included vehicles for the Army and Marines. For clarity, as part of the original JLTV LRIP/FRP Base Award in August 2015, an initial 201 JLTVs for the test and evaluation phase were ordered. The 657-vehicle order is an exercised option from the program's eight option years.

In June 2017 the first US soldiers to receive JLTVs was revealed. According to the Army its first unit to receive JLTVs would be an infantry brigade combat team in the 10th Mountain Division at Fort Drum and according to the Marines, a yet-to-be-identified infantry battalion within II Marine Expeditionary Force at Camp Lejeune, North Carolina, would receive its JLTVs in July 2019. Also in June 2017 the Marines revealed they wished to adjust their acquisition objective for JLTV by 65% to up to 9,091 vehicles.

In August 2017 further details the U.S. Air Force's FY18 budget request for JLTVs were published. Beginning in FY 2019, the first of 140 units could be fielded, these including 46 Utility variants, 48 General Purpose variants, and 46 Heavy Gun Carrier variants, these to be operated by Air Force security forces, explosive ordnance disposal teams, pararescue and personnel recovery units, tactical air control party teams, and special tactics forces. The Air Force wishes to eventually replace its entire inventory of 3,270 Humvees with JLTVs.

On 1 Sept 2017 Oshkosh announced the sixth JLTV order, this including 611 vehicles and 1,789 installed and packaged kits. The order is valued at more than $177 million.

At AUSA 2017 JLTV's were displayed in three new configurations. Oshkosh displayed a General Purpose variant fitted with a Boeing Compact Laser Weapon System (CLWS), a Kongsberg Protector LW 30 Remote Weapon System (RWS) with a M230LF cannon, and a communications suite that includes a Thales VRC-111 and Thales VRC-121 VIPER. The company also displayed a Utility variant equipped with the Boeing Maneuver Short Range Air Defense (SHORAD) Launcher including a M3P .50 cal machine gun, M299 launcher with four Longbow Hellfire missiles, sensor suite, and a communications suite including a Thales VRC-111. Rafael displayed a General Purpose vehicle fitted with the company's Samson RWS Dual Stabilized Remote Weapon Systems (RWS) with M230 LF, and the Trophy Light Active Protection System (APS).
