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.
