The JLTV also has an Allison 2500 special purpose transmission that's installed on it .
It runs up to speed automatic to the drive train
The Joint Light Tac tical Vehicle or JLTV is a US military specifically the US Army,
US Marine Corps, and US Special Operations Command program to
partially replace the Humvee with a family of more survivable vehicles with larger payload.
The development of JLTV is initiated by the Army and the Marine Corps as a successor to
the High Mobility Multi-Wheeled Vehicle which has been in service since 1985.
JLTV construction started in October 2008, where three industry teams received awards
for the joint light tactical vehicle technology development phase. The Army
released a request for proposal for the JLTV's Engineering Manufacturing
Development (EMD) phase in January 2012 which then awarded the EMD contracts to AM General,
Lockheed Martin Corporation, and Oshkosh Corporation in August 2012.
Furthermore, the Army awarded Oshkosh a $6.7 billion low rate initial production
contract with eight options in August 2015 to acquire the first 16,901 vehicles
and authorized JLTV full-rate production. Then, in order to free up funds for other
Army modernization priorities, plans for a program reduction were made in FY 2021
and extend the joint light tactical vehicle procurement by three years until 2042. The
Army has also stated that it plans to complete a follow-on contract to be awarded in FY 2022
intended to split the procurement between Oshkosh and a new competitor in order to reduce costs.
Talking about its technical details, only limited information has been provided by
either the U.S. Army or Oshkosh. The tactical vehicle is built around Oshkosh's TAK-4i
independent suspension system and has the variable adjustable ride-height type with
up to 20 inches of wheel travel, with its suspension aided egress system capability
levels side to side and front to rear on slopes when selected by the operator. The front and rear
suspension height can also be independently controlled for ship and transportability.
For its motive power, it is provided by a digitally-controlled Gale Banks
Engineering 866T V-8 diesel with its power output is 340 hp and fitted by
an Allison 2500SP six-speed fully automatic transmission.
Moreover, the vehicle has been designed to comply with the U.S. Army's Long Term Armor Strategy,
following an A or B-kit principle. The A-kit is fitted on the production line and is a
combination of a limited amount of armoring, in difficult-to-access areas of the vehicle, together
with a significant amount of armor installation attachments and required support structures.
Meanwhile, the B-kit is installed in the field on an as-required basis.
Two soldiers can install B-kit armor in five hours, and an 800-pound RPG protection kit can be
installed in two hours at field-level maintenance, completed by the crew within 30 minutes.
Additionally, this tactical vehicle has an automatic fire-extinguishing system to protect
the crew cabin, in which the fuel tanks are mounted externally and shielded by its structure,
and each crew seat has a combined seat and blast restraint device. The joint tactical vehicle is
also fitted with a diagnostic monitoring system that can monitor the fuel, air intake, engine,
cooling, transmission, energy storage, power generation, and vehicle speed,
among other systems, and will electronically inform the operator of any equipment faults.
For additional information, the only weight-related data officially released
includes a gross vehicle weight of 10,266 lb, with payload for the two-door variant
which is quoted as 2,318 kg, and payload for the four-door variant which is quoted as 1,590 kg.
In regards to its mobility, the vehicle was capable of traveling for three
miles cross-country, it can operate in altitudes from minus 500 to 12,000 feet
and maintain full mission capability in temperatures from −40 to 125 °F.
In addition, it also capable of traveling 350 miles on paved roads at 35 miles per hour or
300 miles in operational terrain on a single tank of JP-8 fuel, as well as acceleration from 0 to 30
miles per hour in 9.7 seconds on dry and hard terrain, and the ability to ford 60 inches of
saltwater without a fording kit in both directions while maintaining contact with the ground.
Other tactically driven mobility requirements include a threshold 27-foot turning radius and
the ability to climb 24-inch vertical obstacles in forward and reverse. This joint light vehicle
needs to drive off an 18-inch vertical step at 15 mph and sustain no mechanical damage which will
be capable of traversing a 20-degree V-ditch that is 25 feet wide at an approach angle of 45-degree.
The tactical vehicle can also 'jump' a 6-inch parallel curb at 15 mph and traverse a 20-foot
flight of stairs at 5 mph. Moreover, the vehicle is transportable on all classes
of ocean-going transport ships with minimal disassembly which is prepared in 30 minutes
for transport by aircraft, Maritime Prepositioning Force ships or rail.
For its variants, the JLTV program has evolved significantly throughout various development
phases and milestones. The variants are capable of performing armament carrier, utility, command and
control, ambulance, reconnaissance and a variety of other tactical and logistic support roles,
which include four seat variants consisting of Heavy Guns Carrier, General Purpose,
and Close Combat Weapon Carrier, and two seat variants consisting Utility.
Lastly, let’s take a look at the Future of JLTV Procurement.
The Army’s current modernization strategy is primarily focused on six modernization priorities
which do not include the Joint Light Tactical Vehicle. The Marine Corps downsized per its March
2020 Force Design Initiative and adoption of a more expeditionary posture, possibly requiring
fewer joint lighter vehicles. The original JLTV procurement plans for the two major service
customers might no longer be relevant. Despite the Army’s intention to save money by competing a
follow-on contract with another vendor by FY 2022, slower production rates and longer procurement
processes can increase the costs. In addition, a mixed fleet of vehicles with different versions of
the JLTV produced by another vendor could result in additional operations and maintenance costs.
Taken collectively, these concerns may warrant the Department of Defense and policymakers looking
into the future of Joint Light Tactical Vehicle procurement, in order to evaluate the current need
and whether actions to extend procurement will result in higher programmatic costs.
That’s all for today. Thanks for watching, and see you next time!
Hey everyone . My name is Sergeant , First class Cory Ray . I'm a unit master driver with 353 civil
affairs and today I'm excited to show you guys are new vehicle that we just got issue . It's
the joint light tactical vehicle also known as the J L T V . All right guys , this is , I'm sure the
moment that you've all been waiting for the inside of the J L T V . The vehicle was designed with
the soldier in mind . Everything from the camel back cut out to the way that the seat goes up and
down to fit every soldier in the army reserves . One of my favorite features in the new JL TV
is the digital display unit . It's a windows based system that gives the soldier total control over
the vehicle . They're able to view temperatures , pressures and the camera views for the front
and the back backup cameras . Okay guys , this is the new JL T V engine , it has a 6.6 liter
turbo diesel that's capable capable of producing 340 ft pounds of torque And 660 hp . If you guys
look , we have the turbo right up in this area that helps the vehicle get up to the maximum
speed that it can get up to which is 76 miles an hour . As you can see we have up armored windows
and doors on the exterior of the vehicle , they're capable of withstanding small arms fire and since
all of the controls are on the inside of the vehicle due to the seals , the vehicle is capable
of going through different operational statuses , from affording mode to operational status to tie
down and it even drops into a loading status . The jail tv has also got extra functions on the back
of the vehicle as well . It's got an installed rear backup camera that's gonna assist with
safety and ground guiding while you're in the motor pool . Uh , speaking of safety , we also
have a black box that's installed in the back of the vehicle that is going to record statistics and
give the command analysis in case of accidents or rollovers . The J . L . T . V also has an
Allison 2500 special purpose transmission that's installed on it . It runs up to speed automatic
To the drive train . Thanks for joining us today guys 353 is excited to have these brand new
vehicles in our fleet and you can look forward to phenomenal civil affairs training and operations
in the very near future . Feel free to drop your comments below and stay tuned for videos to come
