The Joint Light Tactical Vehicle (JLTV) is a United States military (specifically U.S. Army, USSOCOM, and U.S. Marine Corps) program to part-replace the Humvee that is currently in service with a family of more survivable vehicles with greater payload. JLTV traces back to 2005 but publicly emerged in January 2006, with early government requests for information noting: "In response to an operational need and an aging fleet of light tactical wheeled vehicles, the joint services have developed a requirement for a new tactical wheeled vehicle platform that will provide increased force protection, survivability, and improved capacity over the current Up-Armored High-Mobility Multipurpose Wheeled Vehicle (UAH) while balancing mobility and transportability requirements with total ownership costs." The joint service nature of the effort was assured through Congressional language in the Fiscal Year 2006 (FY06) Authorization Act, which mandated that any future tactical wheeled vehicle program would be a joint program. The JLTV program incorporates lessons learned from the earlier and now halted Future Tactical Truck Systems (FTTS) program and other associated efforts. JLTV has evolved throughout various development phases and milestones but variants will be capable of performing armament carrier, utility, command and control (shelter), ambulance, reconnaissance and a variety of other tactical and logistic support roles. JLTV will be manufactured to comply with the US Army's Long Term Armor Strategy (LTAS). The JLTV program was in danger of being outpaced by the rapid development of lightweight MRAPs. The JLTV program (including numbers required and pricing) evolved considerably as the program developed and requirements stabilized. Oshkosh's L-ATV was selected as the winner of the JLTV program on 25 August 2015 and awarded an initial production contract for up to 16,901 JLTVs. Lockheed Martin filed a protest of the award with the Government Accountability Office (GAO) in September 2015. On 15 December the GAO denied this award, Lockheed Martin proposing to file a "Notice of Post-Award Bid Protest" with the US Court of Federal Claims. On 17 February 2016, Lockheed withdrew their protest of the contract award decision. The first JLTV order was placed in March 2016 with the U.S. Army ordering 657 trucks.
