In July 1984 a program to look at a future 5-ton truck procurement to replace in-service 2.5- and 5-ton trucks began. Cost analysis demonstrated that the procurement should be for both 2.5- and 5-ton trucks, and in October 1984 FMTV formally began as a program. The Request For Proposals (RFP) for FMTV was released in 1988. At this time it was expected that around 120,000 trucks would be ordered over three five-year contracts.
FMTV’s origins trace back to a U.S. Army TRAining and DOctrine Command (TRADOC) requirements document issued in 1983 for a Medium Tactical Truck (MTT), the intended replacement for the in-service 2.5-ton truck.
In October 1988, the U.S. Army awarded contracts to Stewart & Stevenson, the Tactical Truck Corporation (a 50/50 joint venture between General Motors Military Vehicles and the BMY Wheeled Vehicle Division of the HARSCO Corporation), and Teledyne Continental Motors for 15 prototype vehicles each, these to be completed by January 1989. One of the companies, Stewart & Stevenson Services, produced a truck based on the Austrian company Steyr’s 12M18 truck and eventually won the first contract in 1991 to produce the US Military’s new Family of Medium Tactical Vehicle (FMTV) fleet. The 2 1/2 ton 4×4 truck variants were named the Light Medium Tactical Vehicle (LMTV) and the 5 ton trucks named the Medium Tactical Vehicle (MTV). Stewart and Stevenson produced the vehicles until approximately 2010 when Oshkosh Defense took over production.
The Family of Medium Tactical Vehicles (FMTV) is a family of diesel powered U.S. Army supply trucks in the 2.5 to 5 ton payload class. There were originally 17 FMTV variants, four 2.5 U.S. ton payload variants designated Light Medium Tactical Vehicle (LMTV) and 13 variants with a 5 U.S. ton payload, these designated Medium Tactical Vehicle (MTV)
The FMTV consists of the Light Medium Tactical Vehicle (LMTV) and the Medium Tactical Vehicle (MTV). The trucks are manufactured by Oshkosh Corporation. A five-year contract was awarded to Oshkosh Trucks in August 2009, unseating incumbent FMTV producers BAE Systems and Navistar Defense. The FMTV Family of Vehicles has 80% part commonality.
The LMTV is a family of 4-wheel (4×4) diesel powered trucks with a 225 HP (A0) or 275 HP (A1) Caterpillar 3116, 3126 and C7 6 cylinder engine. The LMTV has a 2.5 ton payload capacity and consists of the M1078 Cargo, M1079 Van, M1080 chassis and M1081 LVAD models . The M1082 2.5-ton payload trailer is designed to be pulled by LMTV and MTV trucks.
The Medium Tactical Vehicle (MTV) is a family of 6-wheel (6×6) diesel powered trucks with a 290 HP (A0) to 330 HP (A1) Caterpillar 3116, 3126 or C7 6 cylinder engine. The MTV has a 5 ton payload capacity (dump truck has 10 ton payload), and consists of the M1083 MTV Cargo, M1084 MTV Cargo MHE, M1085 MTV Cargo Long Wheel Base (LWB), M1086 MTV Cargo MHE LWB, M1087 MTV Expansible Van, M1088 MTV Tractor, M1089 MTV Wrecker, M1148 MTV Load Handling System (LHS), and M1157 MTV 10 Ton Dump Truck models. MTV trailers include the 5-ton payload M1095 and the M1147 LHS Trailer. Subvariants of the MTV provide an air drop capability for contingency and rapid deployment operations. Commonality between variants significantly reduces operation and maintenance costs.
The FMTV vehicles first went into service in 1996 and capitalize on current up-to-date automotive technology including modern diesel engines, automatic transmission, and central tire inflation system (CTIS). The use of common chassis, engines, tires, and cabs ensures an over 80% commonality of parts between models and weight classes. This significantly reduces the logistics burden and operating costs. Numerous models perform a wide variety of missions including cargo transport. The FMTV also serves as the platform for the High Mobility Artillery Rocket System (HIMARS) and as support vehicle for the Patriot Missile System. FMTV vehicles also support the Warfighter Information Network – Tactical (WIN-T) program; Aviation Ground Support Equipment (AGSE); In October 1998 Stewart & Stevenson was awarded the second FMTV contract, this for 8,000 trucks and 1,500 companion trailers and with a value of $1.4 billion. Total quantities including options were 11,491 trucks and 2,292 trailers, delivered between September 1999 and October 2004. Trucks were the improved A1 model, with improvements including an uprated engine (1998 EPA compliant) and transmission, and the introduction of ABS. The first A1 models were fielded in July 2000.
In a move away from U.S. Army tradition, a Cab Over Engine (COE) design was selected for the FMTV as while the US Army did not specify this configuration, given the Cold War situation prevailing at the time it had indicated that overall length for shipboard transport was a consideration.
On a model-for-model basis the FMTV is around 1 m shorter than its bonneted predecessors, while retaining a C-130 Hercules transport capability. Subject to load dimensions, all original FMTV variants are C-130 transportable at GVWR and all models capable of being transported underslung by helicopter are fitted with a sliding outrigger system. Low Altitude Parachute Extraction System (LAPES), later revised to Low Velocity Air Drop (LVAD) variants of A0 production LMTV (M1081 cargo) and MTV (M1093 cargo and M1094 dump) variants were produced.
The chassis and cab of the FMTV feature extensive corrosion protection. It was the first truck to pass the U.S. Army’s 22-year accelerated corrosion test.
The design of FMTV has never remained static and to further increase reliability, user friendliness and operational flexibilty, detailed refinements/upgrades have continued throughout FMTVs production run.
FMTV is built around a conventional bolted/huck-bolted cold-formed C-section chassis with bolted-in tubular cross-members. The high-grade 758 Mpa steel used is sourced from Sweden. LMTV variants can be fitted with a DP-10J winch with a 4,990 kg line pull. MTV variants use a DP-515 winch with a 7,031 kg line pull.
Current production FMTV A1P2s are powered by a 2007 Environmental Protection Agency (EPA) emissions compliant 7.2-liter six-cylinder Caterpillar C7 diesel engine developing 275 hp and 1166 Nm torque in LMTV variants and 330 hp and 1166 Nm torque in MTV variants. FMTV A1Rs have a 2004 EPA emissions compliant version of the same engine with the same power output. FMTV A1 variants have an earlier 1998 EPA emissions compliant version of this engine, the 3126 ATAAC which developed 275 hp at 2400 rpm and 1107 Nm torque at 1600 rpm in LMTV variants and 330 hp and 1153 Nm torque in MTV variants. A 6.6-liter derivative of this engine, the 3116 ATAAC, was fitted to FMTV A0 models where it developed 225 hp and 863 Nm torque in LMTV variants, and 290 hp at 2600 rpm and 1000 Nm torque in MTV variants.
The Allison 3070 SP seven-speed transmission fitted to A1P2 and A1R FMTVs has also evolved with the FMTV, its A1 designation being MD 3070 PT, its A0 designation being MD-D7. This has an integral single-speed transfer case. All-wheel drive is full-time, with a 30/70 per cent front/rear torque split for on-road driving, and a 50/50 per cent split for off-road driving.
All FMTV models are fitted with Meritor beam axles, the ratings and specifications of which have also evolved as the FMTV has developed. Suspension is by a combination of parabolic tapered leaf springs (inverted on the MTV rear bogie), shock-absorbers, and an anti-roll bar for the rear axle/bogie.
What soldiers do like about the FMTV is its comfortable ride, a shorter turning radius that makes it more maneuverable, and the improved cargo roof. The pitch of the tarp-over-steel bow was increased and replaced tarp over aluminum, after a number of the cargo roofs collapsed under heavy loads.
The FMTV has an unparalleled history of superior reliability and off-road mobility, with an incomparable 13,333 mean miles between hardware mission failure and 98 percent operational readiness. Stewart & Stevenson has produced more than 20,000 FMTV trucks and trailers and has established a record of 37 consecutive months of 100 percent on time delivery of trucks, 28 consecutive months of trailer deliveries and 23 straight months without missing a schedule for spares.
Stewart & Stevenson and Oshkosh Truck Corporation were awarded contracts in April 2001 for the Evaluation Phase (Phase 1) of the FMTV A1 Competitive Rebuy (FMTV A1 CR) program for the next FMTV production contract. Following trials and evaluation, in April 2003 the contract was awarded to Stewart & Stevenson. Production of the FMTV A1 CR (designated FMTV A1R) began in Q3 2004. Improvements to A1R models were numerous and included a new EPA 2004 compliant Caterpillar C7 engine. A total of 21,149 FMTVs and companion trailers were built under the FMTV A1R contract award.
In May 2006, Stewart & Stevenson was acquired by Armor Holdings Inc., and in August 2007, Armor Holdings was acquired by BAE Systems.
The U.S. Army had intended that the Future Tactical Truck System (FTTS) with just two variants would eventually replace virtually all of its tactical wheeled vehicle fleet including the FMTV. FTTS never materialized, however along with inputs from other efforts it continues to be used to define requirements for future U.S. Army trucks. With FTTS already faltering, BAE Systems was awarded a bridging contract in June 2008 for up to 10,000 FMTVs or trailers, the contract including an option (which was exercised) for 10,000 additional vehicles.
In May 2009 BAE Systems, Navistar Defense and Oshkosh Defense each announced they had submitted proposals for the FMTV A1P2 competitive rebuy program to the U.S. Army’s Tank-Automotive and Armaments Command (TACOM) Life Cycle Management Command. In August 2009, the U.S. Army announced that Oshkosh Defense had been awarded the FMTV A1P2 rebuy production contract. The award was protested by both BAE Systems and Navistar.
The FMTV A1P2 rebuy was awarded as a five-year ‘build-to-print’ requirements-type award that at award allowed the U.S. government to order from 0 up to 12,415 trucks and 10,926 trailers through to calendar year 2014. Some FMTV variants are excluded from the rebuy competition, those excluded include specialist FMTV variants such as HIMARS, Patriot, MEADS and LVAD, plus all the armored cabs developed by BAE Systems.
According to the U.S. Army (in February 2012) all FMTV work with BAE Systems (minus a small number of armor B-kits) had concluded, BAE Systems and legacy companies having delivered around 74,000 FMTV trucks and trailers to the U.S. Army.
U.S. budgetary projections of March 2012 suggested that due to funding constraints the FMTV program would be terminated in FY14. Under the FMTV contract orders could be placed until December 2013, with first deliveries to commence within one year of that, with final deliveries one year later. Contract extensions have been made, the latest allowing orders to be placed until September 2016. The most recently announced FMTV order by Oshkosh was in July 2015, this requesting 698 FMTVs worth $184 million, with deliveries to start in 2016.
Since deliveries started in 2010, Oshkosh has received orders for over 24,300 FMTV trucks and 11,400 FMTV trailers.
Early 2014 the U.S. Army’s Program Executive Officer for Combat Support and Combat Service Support (CS CSS) suggested that the Army would be seeking a new medium truck family in the mid-2020s.
FMTVs are currently being reset at the Red River Army Depot on return from deployed operations, and current projections are for a Recap (Recapitalization) program to commence in 2020/2021.
Medium Extended Air Defense System (MEADS); CAMEL II Unit Water Pod System; and the Terminal High Altitude Area Defense (THAAD) system.
As of October, 2016 over 80,000 trucks and over 20,000 trailers were in field units.
Price/Unit Cost: In FY 2015, the unit cost of the M1078 LMTV Cargo Truck was $184,317. The unit cost of MTV Trucks is in the $200,000-$300,000 range depending on variant – with a few exceptions such as the M1087 MTV Expansible Van and M1089 MTV Wrecker (see detailed prices for different models in the specs section at the end of this page).
Mission/Role: The FMTV provides unit mobility and resupply of equipment and personnel for rapidly deployable worldwide operations on primary and secondary roads, trails, cross-country terrain, and in all climatic conditions. It is strategically deployable in C-5 Galaxy, C-17 Globemaster, and C-130 Hercules military transport aircraft.
In 2017 the U.S. Army awarded Oshkosh Defense two additional FMTV contracts valued at approximately $300 million
IN 2017 Israel awarded Oshkosh Defense an FMTV contract valued at approximately $200 million
In 2017 Oshkosh Defense celebrated the delivery of its 25,000th FMTV delivery to the U.S. Army
In 2017 The U.S. Army (TACOM) commenced the RFP process to design and build the FMTV A2, a faster, more powerful, more comfortable FMTV with higher payload capacities. Reportedly, Oshkosh Defense, Mack Defense and AM General are responding.
