The Oshkosh L-ATV ( Tactical All-Terrain Vehicle Combat ) is a light multi-role utility/combat vehicle that won the US Army Tactical Army Tactical Joint Vehicle (JLTV) program. In the early stages of the program, it is recommended that JLTV will replace the AM General High Drive General Drive (HMMWV) Drivers on a one-for-one basis. It is now suggested that JLTV will replace the HMMWV section, not replace it with a like-to-like basis.
Oshkosh's L-ATV will provide the same level of protection as the current one, but the much heavier and less maneuverable Resistant Ambush Shield (MRAP) class design has more protection from explosions than the latest up-armored HMMWV.
On August 25, 2015, L-ATV was selected as the winner of the JLTV program. The first JLTV shipping order was placed in March 2016 with the US Army ordering 657 trucks. Overall the JLTV requirement is 5,500 vehicles for the Marine Corps entering service on FY 2020 with everything to be delivered on FY 2022, and 49,099 for the Army enters service by the end of 2019 with deliveries going through 2040. The Army received the first seven JLTV for the test at end of September 2016, Colonel Shane Fullmer, project manager of JLTV stated on AUSA media briefing 2016.

History
​​â € <â €
The idea for the Joint Light Tactical Vehicle (JLTV) first appeared in 2006 from the threats experienced during the Iraq War. The main tactical wheel vehicle used by the US military at the start of the war was the Humvee. However, it did not rust and was built for charge mobility, so its kind suffered huge losses when improvised explosive equipment (IED) began being employed by the rebels. The initial response was to add the armor to the existing Humvee, and especially on the side. This enhanced side protection against direct fire and associated threats, but because the chassis is not designed to handle additional weight gain, there is little room for bottom protection. The additional weights have an impact on overall reliability and jeopardize off-road mobility.
To combat the increasing number of IED attacks, the US spends about $ 50 billion quickly gaining about 29,000 Resistant Ambush Protect (MRAP) vehicles, including Oshkosh M-ATV for use in Iraq and Afghanistan. Although MRAP offers superior protection from IEDs, especially lower body explosions, MRAP is significantly larger and heavier and has poor off-road mobility. The military incorporated MRAP in response to operational needs, but never asked them to be a permanent part of their fleet of tactical wheeled vehicles. At the end of the operation, many thousands are removed, adapted for other roles, or offered for sale/transfer to allies. Ultimately the US armed forces will retain more than 11,100 MRAPS, just over 6,350 from the Oshkosh M-ATV. Most of the remaining MRAPS will eventually be littered in the stock of prepositions around the world.
Since up-armoring Humvee and buy MRAP are addressed for specific issues but creating gaps in vehicle capabilities, the JLTV program begins to combine the lessons learned and the balance of payload, mobility, and protection into new vehicles. The goal is to restore mobility commander with the original Humvee, while having the side and bottom protection of the body from the basic MRAP. That would be about two-thirds the weight of MRAP, probably to be carried under CH-47 Chinook and CH-53E Super Stallion and by amphibious ship, the impossible for MRAP. It will also be 70 percent faster off the beaten path, adding to the endurance by allowing it to get out of the battle situation faster. Compared with the Humvee, the JLTV has an early, unequipped version of mobility with better protection than the enhanced version, along with greater reliability, load capacity, and ease of repairs. JLTV is the first vehicle built specifically for network connectivity into the Warfighter Information Network-Tactical.
Opening and testing
Oshkosh Defense first showcased L-ATV at the United States Army Association (AUSA) in Washington, DC on October 10 to October 12, 2011. This first 'public view' for design, is not an open appearance and comes form a closed joint briefing/view is only for invitees invited. Oshkosh explained to Jane's Independent Defense Review that the L-ATV had a developmental origin that tracked back to 2007 and failed failed Oshkosh/Northrop-Grumman JLTV proposal, with several sub-systems having lineages tracking back to 2005. At that time, L-ATV is the lightest tactical vehicle designed by Oshkosh, being about 50% lighter than anything previously produced by the company.
At AUSA 2011, Oshkosh suggests that following recent program developments, L-ATV will be offered to meet the newly revitalized EMD (Engineering & amp; Manufacturing Development) JLTV phase. On January 26th, 2012, RFP for EMD Phase JLTV was released. On August 23, 2012, the Marines and Marine Corps chose Oshkosh Defense L-ATV, as well as Lockheed Martin JLTV entry and AM General BRV-O, winning 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 assessed by the service.
On February 6, 2013, Oshkosh introduced the Utility Varian of its JLTV offering, meeting the JLTV requirements for a two-seater cargo vehicle. The performance of the vehicle was demonstrated in 2013 NATC Technology Rodeo at Nevada Automotive Test Center (NATC). Utility variants are designed to provide mobility for cargo such as containers, pallets, and bulk cargo breakers. It can also be equipped as a shelter carrier to carry a standard shelter for communication systems, on-board electronics, and other functions. Load capacity over 5,100 pounds. Both variants of the Oshkosh L-ATV utilize the patented general crew protection system, automotive systems, and intelligent Oshkosh TAK-4i (TM) intelligent suspension system.
In June 2013, the L-ATV prototype participated in an event hosted by the JLTV US Joint Program Office in Quantico, VA. The vehicle successfully completed a severe off-road trajectory (SORT) without failure. SORT demonstrates L-ATV's ability to maneuver steep climbs, turn sharp, and operate in heavy terrain. On August 8, 2013, Oshkosh delivered his first JLTV L-ATV prototype to the Army for government testing after a successful vehicle inspection by the Defense Contract Management Agency (DCMA). The four-door variant (which has two basic platforms - Combat Weapons Carrier (CCWC) and General Purpose (GP)) and two-door Utility Variant are provided for evaluation.
On August 27, 2013, the Army and Marine Corps announced that the full-scale JLTV prototype testing will begin the following week, with all three vendors sending 66 vehicles. Each company sends 22 vehicles and six trailers to Aberdeen Proving Ground, Maryland, and Yuma Proving Ground, Arizona. Previous tests have put the vehicle through more than 400 ballistic and blast testing on armor test samples, undercarriage testing, and over 1,000 miles in search testing. Soldiers from the Army's Test and Evaluation Command and personnel from the Defense Department's Office of Test and Evaluation will begin putting the vehicle through realistic and rigorous field testing for 14 months of government performance testing. Testing is scheduled for completion in FY 2015, with production contracts to be awarded to single vendors for nearly 55,000 vehicles (49,099 Army, 5,500 Marines). Average manufacturing unit cost in A-kit configuration (fitting for but not with armor) does not exceed $ 250,000. The Army establishes Initial Operating Capability (IOC) in May 2018 and is planned to complete its field on FY2040. Marines have IOC December 2017, and are planned to complete the field on FY2022. On 3 September 2013, full-pace JLTV testing, full-scope starts at Aberdeen Proving Ground, Yuma, and Redstone Arsenal, Alabama. One vendor will be selected in July 2015, and generates 2,000 vehicles for three additional test years to perfect the assembly line and complete the system.
In July 2014, L-ATV completed the Net-Ready testing as part of the JLTV program, involving the transfer of data from the onboard system to the external network. On July 17, 2014, Oshkosh announced L-ATV has completed 200,000 miles and all requirements for Reliability, Availability, Maintenance (RAM) testing. On November 19, 2014, Oshkosh announced L-ATV had completed a Limited User Testing (LUT) with the US Army and Marine Corps for the JLTV EMD contract. LUT focuses on JLTV system capabilities, functions, operations, and interfaces in a variety of simulated tactical environments that include operator-level and crew-level preventive maintenance for the entire system, ensuring they can operate proficiently and securely. The Army held them back in September and October before, in which three tests were held as 96-hour cycles to simulate operational missions, one of which included a live fire demonstration. The Marines completed two test cycles in October and November with a live fire demonstration. The Army released the JLTV RFP final on December 12, 2014. On February 10, 2015 Oshkosh Defense issued a press release announcing the company has submitted a proposal (L-ATV) in response to the JLTV Low Rate Initial Production (LRIP) and Full Rate Production (FRP) RFP.
On March 31, 2015, Oshkosh announced it would show its JLTV offering, L-ATV, at the AUSA 2015 Global Force Symposium and Exposition in Huntsville, Alabama. The company also announced it will show a Virtual Task Trainer (VTT) for L-ATV at the conference. VTT is an interactive training module that provides interactive 3D training for soldiers in a secure and live virtual environment. Speaking of VTT, Mike Ivy, vice president of global integrated product support for Oshkosh Defense said: "The addition of Oshkosh virtual training to our multi-faceted curriculum reduces operator training costs by increasing the effectiveness and efficiency of training." He added: "We deployed VTTs to train operators during the initial JLTV testing with good results.People are really involved, and our training is not only better, but it also takes less time than without VTT This shows significant costs. savings for the government. "
Selection and production of JLTV
On August 25, 2015, the Army chose Oshkosh L-ATV as the winner of the JLTV program. The company earned an initial $ 6.75 billion base contract with eight year options to acquire the first 16,901 vehicles for the Army and Marines. CEO of Oshkosh, Charles Szews, said the award of the production contract will involve more than 300 suppliers in 31 countries around the country. The Army initially refused to explain why L-ATV was chosen over its competitors, perhaps in anticipation of protests by losing bidders.
On September 8 it was revealed that Lockheed Martin would protest the award to Oshkosh; on the same day it was also revealed that AM General had decided not to protest. Any work to be performed under a contract stops during the review period. On 15 December the Government Accountability Office (GAO) refused Lockheed Martin's protest because the company on December 11 decided to file a "Notice of Post-Prize Bid Protest" with the US Court of Federal Claims; according to sources with knowledge of the procedure, it is not unusual for a company to file with a court close to the GAO's protest decision. As soon as GAO refused to protest, the Army instructed Oshkosh to resume work on JLTV's orders. Lockheed filed their preliminary directive on December 17, claiming that new information provided by the contract-related Army appeared near the end of the GAO protest process that was not considered before their decision and no extension of the deadline was granted. On February 17, 2016, Lockheed withdrew their protests against the decision of the JLTV contract decision at the Federal Claims Court, potentially as a result of the release of JLTV testing data showing that the L-ATV lasted nearly six times longer between significant damage than the Lockheed vehicle.
The first JLTV order was announced on March 23, 2016 with the US Army ordering 657 JLTV. The $ 243 million order includes vehicles for the Army and Marines. For clarity, as part of the original JLTV LRIP/FRP Base Award in August 2015, the initial JLTV 201 for the testing and evaluation phase was ordered. The order of 657 vehicles is an option made from the eight year program options.
In June 2017, the first US troops to receive the JLTV were revealed. According to the Army, its first unit to receive the JLTV will be an infantry brigade team in the 10th Mountain Division at Fort Drum and according to the Marines, unidentified infantry battalions in the Expedition II Navy at Camp Lejeune, North Carolina, will receive its JLTV in July 2019. Also in June 2017 the Marines revealed they wanted to adjust their acquisition goals to JLTV by 65% ​​to 9,091 vehicles. For clarity, the overall JLTV requirement remains 5,500 for USMC and 49,099 for the army.
In August 2017, further details of the US Air Force's FY18 budget request for JLTV were published. Beginning in FY 2019, the first of 140 units can be derived, including 46 Utility variants, 48 ​​General Purpose variants, and 46 Heavy Gun Carrier variants, operated by Air Force security forces, explosive weapons explosives, pararescue and recovery unit personnel, a team of tactical air control teams, and special tactical forces. The Air Force wants to eventually replace its entire inventory of 3,270 Humvees with JLTV.
On September 1, 2017 Oshkosh announced the sixth JLTV order, including 611 vehicles and 1,789 packaged and packaged packages. The order is worth more than $ 177 million. Oshkosh also confirmed JLTV remains on-schedule and on-budget.
In AUSA 2017 JLTV is featured in three new configurations. Oshkosh features a General Purpose variant equipped with the Boeing Compact Laser Weapon System (CLWS), Kongsberg LW 30 Remote Weapon System (RWS) Protector with M230LF cannon, and communication suite that includes Thales VRC-111 and Thales VRC-121 ULAR BERBIS. The company also features Utility variants equipped with Boeing Maneuver Short Range Air Defense (SHORAD) Launcher including M3P.50 cal machine gun, M299 launcher with four Longbow Hellfire missiles, sensor suites, and communication suite including Thales VRC-111. Rafael features General Purpose vehicles fitted with Samson RWS Dual Stabilized Remote Weapon Systems (RWS) with M230 LF, and Trophy Light Active Protection System (APS).
On December 21, 2017, Oshkosh announced the seventh JLTV order, which is worth $ 100.1 million and includes 258 vehicles and installed equipment and related packages. It is also announced today that up to now more than 1,000 JLTV have been delivered. On February 5, 2018, Oshkosh announced the Eighth JLTV order, worth $ 106 million and included 416 vehicles and installed equipment and related packages. This eighth sequence makes the total JLTV ordered to date to 3,430. Full production should commence in November or December 2019 before launch, and initial operating capability is expected for early to mid 2020. For clarity, the overall JLTV requirement remains 5,500 for USMC and 49,099 for the army.
Foreign interests
In June 2016, the British Ministry of Defense (MOD) confirmed that it was discussing the possibility of Foreign Military Sales (FMS) with the US military for L-ATV. This vehicle is being considered for the Package 1 UK Vehicle Package (MRV-P) Package 1 requirement for carrying troops and other light duty, part of the program to equip the Army with several types of armored wheeled vehicles to support rapid deployment and regular forces. It is not uncommon for the US government to make FMS sales until there is a full production level decision on the equipment, but that requirement is negligible given the overall maturity of the JLTV platform. In July 2017, the Department of Defense announced the UK plans to spend up to US $ 1.04 billion to supply the British military with a maximum of 2,747 vehicles.
The Lithuanian Ministry of Defense (MoF) has contacted the US Department of Defense regarding the possible acquisition of about 200 lightweight Oshkosh L-ATV tactical vehicles. Based on the proposed acquisition, an undisclared value, delivery is scheduled to begin in 2021.
Maps Oshkosh L-ATV
Design
L-ATV is based around the independent Oshkosh TAK-4i (i = intelligent) independent suspension system. Approximately 26,000 military vehicles are equipped with previous system versions, including the Tactical Medium Oshkosh (MTVR) Takeover, Oshkosh Logistics Vehicle Replacement (LVSR), and Oshkosh MRAP All-Terrain Vehicle (M-ATV); The TAK-4 system has also been retro-fitted to Force Protection Inc. Cougar and BAE Systems RG-33 MRAP. Most of the systems supplied to date have been triggered by coils. The TAK-4i version mounted on the L-ATV is still undisclosed, but is not triggered by the coil and is a high-rise type variable that can be adjusted to wheel travel by 20 inches (51 cm), 25 percent more than the current standard..
The motive power for the JLTV variant of the L-ATV is provided by the digitally controlled Gale Banks 866T V-8 diesel engine, based on the Duramax General Motors (GM) architecture. The power output is concealed but is estimated to be around 300 hp. In the use of commercial power output from the current Duramax engine up to 397 hp (296 kW) at 3000 rpm. The fully automatic six-speed Allison Transmission that is not specifically installed, is combined with the Oshkosh transfer case. It is not currently known whether this is a case of single or two speed transfer (high/low). The L-ATV can be equipped with the Oshkosh ProPulse diesel-electric powertrain, previously mounted to the Heavy Weight Mobility Heavy Truck Oshkosh (HEMTT) and MTVR. According to the Oshkosh literature, ProPulse's diesel-electric powertrain dramatically improves fuel economy by up to 35 percent under certain circumstances and serves as an on-board generator with sufficient output to power an entire airfield or hospital, generating up to 120 kW AC power for external operation ; hybrid powertrain is not a requirement of JLTV program. In the Limited User Test (LUT), L-ATV shows the reliability of 7.051 "Mean Miles Between Operational Mission Failure," more than Humvee and other JLTV competitors.
L-ATV offers a higher level of protection than up-armored HMMWV and is comparable to the original design of the MRAP class, but in the overall vehicle package that is much smaller and lighter than the vehicle obtained under the US Marapir MRAP procurement. L-ATV fully conforms to the US Army's Long Fleet Strategy (LTAS), based on the principle of modular armor A-kit/B-kit. A-kits, installed during construction, are primarily equipment for additional armor but may include a small number of armor mounted in hard-to-reach areas. The B-kit is basically an add-on armor, this is added when needed and as a modular plugin. According to the US Army, the concept of A-kit/B-kit allows the flexibility of the Army in several areas: armor B-kit can be released when not needed - reducing unnecessary wear on the vehicle; The Army may continue to seek enhanced armor protection - adapting B-kit to fit the threat; and the versatility of B-kits enables the transfer of armor from unit to unit - making affordable armor requirements by collecting assets rather than purchasing single-vehicle armor. Oshkosh developed a CORE 1080 crew protection system for the vehicle, which consists of hull design, armor material, fire extinguish system, and energy-absorbing floors, seating and restraint systems for crew members and storage.
The Oshkosh M-ATV, acquired primarily for Afghanistan where the earlier and larger/heavier MRAPs have mobility problems, has protection comparable to the original MRAP design, but while the smaller ones are still relatively large vehicles. During the L-ATV design process, each component is optimized for survival, resulting in the same level of protection in a 30 percent smaller vehicle. This results in a curb weight for the 14,000 pounds (6,400 kg) JLTV requirement, nearly a third the weight of the heavier MRAP model (4x4), and nearly half the weight of the original MRAP model. The charge allowance for JLTV in Combat Tactical Vehicle (CTV) configurations is four passengers and 3,500 lb (1,600 kg) of cargo, and the Combat Support Vehicle (CSV) configuration is two passengers and 5,100 lb (2,300 kg) of charge.
The L-ATV base does not have standard armament, but can be equipped with weapons options including light, medium and heavy machine guns, automatic grenade launchers, or anti-tank control missiles (ATGM) depending on user requirements. The weapons can be operated from a remote ring or weapon station. Smoke grenade launchers for self-defense can also be installed if needed.
The JLTV family and its nomenclature developed during the development process and to date the US Army has allocated M designations for four individual JLTV configurations. The JLTV family now consists of three basic vehicle platforms, Utility (JLTV-UTL), Close Combat Weapons Carrier (JLTV-CCWC) and General Purpose (JLTV-GP). Utility base vehicle platform is a two-door configuration, the basic vehicle platform of Vehicle Use and Combat Cap is a four-door configuration. Standard US M-designators applied basic vehicle platforms when equipped with certain Mission Packet Configurations. This is currently:
- M1278 Heavy Guns Carrier - General Purpose vehicle platform (JLTV-GP) in Heavy Guns Carrier Mission Package Configuration
- M1279 Utility - Utility (JLTV-UTL) basic vehicle platform in Utility Mission Package Configuration
- M1280 General Purpose - General Purpose vehicle platform (JLTV-GP) in General Purpose Destination Package Configuration
- M1281 Close Combat Weapons Carrier - Combat Weapons Weapons Carrier (JLTV-CCWC) base vehicle platform at Combat Weapons Carrier Mission Package Configuration
There is also a companion trailer (JLTV-T), this can be coupled by all variants of JLTV.
