Oshkosh M-ATV Features, Photos and Videos

The Oshkosh M-ATV is a Mine Resistant Ambush Protected (MRAP) vehicle developed by the Oshkosh Corporation for the MRAP All Terrain Vehicle (M-ATV) program. Intended to replace M1114 HMMWVs, it is designed to provide the same levels of protection as the larger and heavier previous MRAPs but with improved mobility.

In the summer of 2008, the U.S. Department of Defense (DoD) began to examine the possibility of developing and procuring a lighter-weight, all-terrain capable MRAP variant to address the poor roads and difficult terrain of Afghanistan. Source selection activity considered responses from more than 20 companies to a Request for Information (RfI)/Market Survey dated 21 August 2008 and in mid-November 2008 the U.S. government issued a pre-solicitation for an M-ATV. In early December 2008 the M-ATV formal Request for Proposals (RFP) was issued. The original M-ATV program requirement was for between 372 and 10,000 vehicles, with the most probable production quantity stated as 2,080.

In March 2009, it became known that two each of six different vehicle types (from five manufacturers) had been delivered to the U.S. Army for two months of evaluation, at the conclusion of which up to five ID/IQ (Indefinite Delivery/Indefinite Quantity) contracts would be awarded. In addition to Oshkosh's proposal, BAE Systems submitted two proposals, these being a Joint Light Tactical Vehicle (JLTV) derived design and an FMTV-based Caiman derivative. Force Dynamics (a Force Protection/General Dynamics Land Systems (GDLS) joint venture) offered Cheetah, GDLS-C (Canada) offered an RG-31 MRAP derivative, and Navistar offered an MXT-based solution.

After GDLS-C's RG-31 was eliminated from the competition in May 2009, it was announced that the five remaining bidders had been awarded ID/IQ contracts, and were each to deliver three production-ready test vehicles for the next stage of the competition. At the completion of testing, the U.S. DoD stated that it planned to select a single M-ATV producer but could, at its discretion, place production orders with multiple producers as it had done with the initial MRAP procurement. On 30 June 2009, the M-ATV contract award was announced with a single ID/IQ contract award to Oshkosh. Brigadier General Michael Brogan, United States Marine Corps program officer for MRAP, stated that the Oshkosh M-ATV was chosen because it had the best survivability and Oshkosh had the best technical and manufacturing capabilities of all the competitors. The Oshkosh bid was also the second cheapest.

The initial M-ATV delivery order was valued at over $1 billion and included 2,244 M-ATVs. The overall M-ATV requirement had increased in early June from 2,080 to 5,244 M-ATVs, these split 2,598 (Army), 1,565 (Marines), 643 (U.S. Special Operations Command), 280 (Air Force), 65 (Navy), and 93 for testing.

In July 2009, the first 46 M-ATVs were delivered, and in November the 1,000th M-ATV was handed over. Oshkosh reached its contractual obligation to produce 1,000 M-ATVs per month ahead of schedule in December 2009, and by using its existing manufacturing facilities in Oshkosh, WI (50%), and making use of its recession-hit JLG telescopic handler facility in McConnellsburg, PA (50%). The first vehicles arrived in Afghanistan in October 2009 and were to be all delivered by March 2010.

In total 8,722 M-ATVs were delivered to the U.S. Army, U.S. Marine Corps, U.S. Air Force, and U.S. Special Operations Command (SOCOM). M-ATVs were delivered in two main variants. The base model is designated M1240 with the Objective Gunner Protection Kit [OGPK] manned turret; it is designated M1240A1 when fitted with the Underbody Improvement Kit (UIK). The second main variant is designated M1277 and is fitted with M153 CROWS remote-controlled weapon station (RCWS). Produced in smaller numbers, the SOCOM-specific variant is designated M1245; M1245A1 with UIK fitted.

As part of the overall divestiture of the MRAP fleet, the U.S. Government will keep about 80% (around 7,000) of the M-ATV fleet, 5,651 of these (inc. 250 for SOCOM) to be retained by the Army. Work is currently underway at Oshkosh's Wisconsin facility and the Red River Army Depot to reset the around 7,000 M-ATVs retained to a common build standard. Oshkosh was awarded an initial 500-vehicle M-ATV Reset contract in August 2014. Three additional contract options for 100 vehicles each were awarded in December 2014. Total contract value is in excess of US$77 million. Deliveries were scheduled to continue through September 2015.

Reset work centers on returning vehicles to Low Rate Initial Production (LRIP) 22 standard: essentially the build standard for the final M-ATV production batch. LRIP 22 includes upgrades such as the UIK and enhanced Automatic Fire Extinguishing System (AFES). Reset work also adds Engineering Change Proposals (ECPs) that include acoustic signature reduction (muffler), Modular Ammunition Restraint System (MARS) ammunition storage, and some Government Furnished Equipment (GFE) relocation.

On 28 May 2015, Oshkosh announced the U.S. Army had awarded it a contract modification for the reset of 360 additional M-ATVs. The modification includes options for the reset of up to 1,440 additional M-ATVs. Deliveries for this latest modification started October 2015. Oshkosh is on contract to reset a combined 1,160 M-ATVs with a total value of over $115 million.

In January 2017, the US Marine Corps disclosed that they would upgrade and refurbish around 80 M-ATVs over a five-month period, the work scheduled to take three to four weeks for each M-ATV and cost around $385,000 per vehicle, with both Marine and Air Force M-ATVs involved. The main difference between the two services M-ATVs is the armament; Air Force M-ATVs are fitted with a CROWS (Common Remotely Operated Weapon Station), while Marine M-ATVs are fitted with a manual OGPK (Objective Gunner Protection Kit) turret.

At the Association for Unmanned Vehicle Systems International (AUVSI) 2013 convention, Oshkosh announced the integration of the TerraMax system onto the M-ATV to allow the type to be converted into an unmanned ground vehicle. The goal is to use the M-ATV as an unmanned platform for route clearance and counter-IED missions by engineers.

Oshkosh Defense unveiled the M-ATV Extended Wheel Base Medical (EXM) variant at the International Defense Exhibition and Conference (IDEX) 2015 (22–26 Feb.) in Abu Dhabi, United Arab Emirates. This variant of the M-ATV has enough interior capacity to simultaneously transport two litter-bound patients, two ambulatory patients, a medic, commander and driver. The M-ATV EXM’s customizable internal configuration also enables equipment to be accessed quickly by a centrally positioned medic.

In February 2015, Oshkosh Defense and Alliant Techsystems conducted a firing demonstration of the M230LF 30 mm chain gun on an M-ATV to demonstrate the viability and effectiveness of a medium caliber weapon system for light tactical vehicles. The live fire demonstration showcased improved accuracy in mobile engagements and improved lethality on the M-ATV using the gun, mounted on the R400S-Mk2, a 3-axis stabilized remote weapon station weighing less than 400 kg (880 lb). The addition of the 72.6 kg (160 lb) M230LF stabilized on the RWS provides mobile precise lethality, usually reserved for heavier combat vehicles, with exceptional off-road mobility and MRAP levels of protection.

The M-ATV proved to be more survivable than the Humvee and was lighter than other MRAP versions, but to further enhance survivability and mobility for troops, the U.S. military undertook the Joint Light Tactical Vehicle (JLTV) program to obtain a vehicle combining light weight, mobility, and protection. In August 2015, Oshkosh was awarded the contract for their Light Combat Tactical All-Terrain Vehicle (L-ATV), which took design lessons from fielding the M-ATV and incorporated them into a truck at two-thirds the weight and with faster off-road speeds.

By 2018, the Marine Corps was deploying a Counter-Unmanned Aerial System (C-UAS) that can be mounted onto an M-ATV. The Ground-Based Air Defense (GBAD) Counter-UAS system consists of the RPS-42 S-band radar, the Modi electronic warfare system, visual sensors and Raytheon Coyote anti-drone UAV to detect, track and destroy hostile drones.

The M-ATV combines a Plasan designed armored hull developed for the Northrop Grumman/Oshkosh JLTV Technology Development (TD) phase proposal with some elements of the Medium Tactical Vehicle Replacement (MTVR) chassis and Oshkosh's TAK-4 suspension system. TAK-4 suspension is coil sprung and fully independent, and offers 16 inches of wheel travel.

For survivability, and in addition to the V-shaped hull which is optimized for IED protection, other aids include the ability to take a 7.62 mm round to the engine oil/coolant/hydraulic system and continue to drive for at least one kilometer. The engine compartment is also protected with the Stat-X engine fire suppression system. A central tire inflation system (CTIS) and run-flat inserts allow the M-ATV to travel at least 30 miles at 30 mph even if two tires lose pressure. The M-ATV also features a traction control system and anti-lock brakes.

Armament is roof-mounted and can be either manually or remotely operated. Manual options include a M240 machine gun, a Mk 19 grenade launcher, an M2 Browning machine gun, a MILAN anti-tank guided missile, or a BGM-71 TOW anti-tank guided missile launcher. Remote option is usually the CROWS (Common Remotely Operated Weapon Station), however as previously mentioned, Oshkosh has also fitted for demonstration purposes the R400S-Mk2, a 3-axis stabilized remote weapon station.

Other M-ATV features include a HVAC system and power outlets for charging portable electronic devices. The M-ATV is also unique among MRAP-type designs in that the rear doors are of the so-called suicide-type.
