Light Tactical Vehicle

The Light Tactical Vehicle [LTV] Program is envisioned to encompass Non-Developmental (NDI) acquisition for a next generation HMMWV vehicle to supplement the existing fleet of HMMWVs in the US Army. It also includes programs intended to provide service life extension and technical up grades to the existing fleet of HMMWVs.

The Light Tactical Vehicle is a Non-Developmental Item (NDI) acquisition program for the U. S. military. The LTV may consist of two chassis configurations. The light configuration will have a payload rating of 2600 lbs and the heavy configuration will have a payload rating of 4500 lbs ( 4,999 lbs desired). The light chassis will be capable of supporting the Light Utility Vehicle model. The heavy chassis will be capable of supporting the Heavy Utility Vehicle and Armored Vehicle models. The LTV will be transportable by C-130 and larger aircraft, rail and marine transport modes. The LTV shall operate on JP8; be capable of being towed, performing self-recovery, recovering equivalent vehicles and mounting a tow pintle. These vehicles shall be capable of operating under on-road/off-road conditions and withstand the strain, shocks, vibrations and other detrimental conditions incident to off-road travel and operation. The LTV shall be capable of meeting all characteristics specified herein throughout a life cycle mileage profile consisting of 30% primary roads, 30% secondary roads, and 40% cross country operations, while carrying specified loads. The LTV shall be capable of operating over cross country terrain, trails, secondary, and primary roads and for the appropriate mobility level specified herein and under the varied environmental conditions encountered.

The Armored Vehicle variant shall have an overall 0.95 probability of no penetration at a 90 percent confidence level against the 7.62 NATO Armor Piercing (AP) M61 round, fired horizontally over 0 to 360 degrees attack directions to the crew compartment at a 100 Meter equivalent velocity. Hit spacing shall be no more than three inches (center to center) required, 3 projectile diameters desired. It is desired that the Armored Vehicle have overall 0.95 probability of no penetration against 12.7mm AP M2 ammunition at a range of 250 meters, fired horizontally over 0 to 360 degrees attack direction to the crew compartment. 3.6.3.2 Underbody Protection. The Armored Vehicle shall provide protection for the crew against mine blasts of up to 12 lbs. TNT when detonated under the tires. The crew compartment shall remain unaltered after a 12 lbs TNT detonation under any wheel (desired, any location). The crew shall be 0 percent incapacitated when 12 lbs of TNT are detonated under any wheel. The Armored Vehicle shall be equipped with a primary weapon mount located on the roof. The weapon mount shall accomodate self defence weapons (M2, M60, M240, M249 Machine Guns or MK-19 Grenade Machine Guns) including ammunition can.

The PM LTV program will meet the Army's needs for light tactical vehicle fleet requirements through a combination of new procurement for HMMWVs, HMMWV remanufacture programs and possible acquisition of Non-Developmental Vehicles to be used in lieu of HMMWVs. The intent of the acquisition programs are to meet established operational requirements and upgrade selected HMMWV Basic and A1 vehicles in order to extend their useful lives and incorporate current components and safety features. The program framework moves to upgrade the HMMWV fleet to incorporate optimized automotive technologies to reduce Operations and Support (O&S) costs, accommodate current operational requirements and provide Human Factor improvements. In addition, the program plans to remanufacture selected HMMWV Basic and A1 vehicles (if supportable through market survey and cost analysis). An on-going Analysis of Alternatives (AOA) study will address program timing and various procurement options and strategies to meet light tactical fleet needs.
