Oshkosh Defense Awarded Support Contract for M-ATV Family of Vehicles

Oshkosh Defense has been awarded a contract for System Technical Support and System Sustainment Technical Support services for the Mine Resistant Ambush Protected All-Terrain Vehicle (M-ATV) family of vehicles.

The contracting activity of the ost-plus-fixed-fee contract, worth $13.9 million, is U.S. Army Contracting Command (ACC) located in Warren, Michigan. Work locations and funding will be determined with each order, with an estimated completion date of July 31, 2021.

Oshkosh M-ATV is a Mine Resistant Ambush Protected (MRAP) vehicle developed by the Oshkosh Corporation for the U.S. Army 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.

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 (ATGM0, or a BGM-71 TOW ATGM launcher. Remote option is usually the CROWS (Common Remotely Operated Weapon Station) but Oshkosh has also fitted the vehicle the R400S-Mk2 3-axis stabilized remote weapon station for demonstration purposes.

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.

In total, 8,722 M-ATVs were delivered to the U.S. Army, U.S. Marine Corps (USMC), U.S. Air Force (USAF) and U.S. Special Operations Command (SOCOM).
