US Military Adds Heavy Trucks Under FHTV-III


US Military Adds Heavy Trucks Under FHTV-III
26-Feb-2009


With its bridge buy of FMTV medium trucks in place and the re-compete proceeding, and initial awards for the potential JLTV Hummer replacement designs underway, the next order of business on the US Army’s agenda was a new Family of Heavy Tactical Vehicles multi-year contract: FHTV-III.
Oshkosh has provided the core of this capability for over 20 yeas now. Its Heavy Expanded Mobility Tactical Trucks (HEMTT) and their 13-ton payloads are the mainstay of the FHTV fleet, serving in variants that include M977/985 Cargo, M978 Fueler, M982/983 Tractors, and M984 Wrecker; they also serve as heavy transporters for Patriot and THAAD air defense systems. M1074/75 Palletized Load Systems (PLS) and PLS trailers (PLST) are best known for their automated container/pallet loading arms, and for their Universal Power Interface Kit (UPIK) that can add modules for firefighting, construction, cranes, et. al. The M1000/1070 Heavy Equipment Transporters (HET) are flatbeds that can transport a 70-ton Abrams tank – or anything less – in order to save wear and tear on expensive armored vehicles and on the roads. A specialized FHTV truck called the M1977 CBT can even lay bridges.


Now the multi-billion dollar FHTV-III contract has been awarded – not as a re-compete like FMTV, but as a single solicitation. The new LTAS armoring kits are also attracting contracts. The latest awards include a major delivery order for over 1,000 trucks…

FHTV: Upgrades, LTAS, and RECAP

Most of the US Army’s HEMTT trucks are the A2 version; Oshkosh celebrated the delivery of the 20,000th HEMTT truck on Feb 14/08. The HEMTT A4 is the latest improvement to the line. HEMTT A4 will be produced in several models, including the M997A4 cargo truck, the M978A4 fuel servicing truck (tanker), the M1120A4 load handling system variant, M982A4 and M983A4 tractors for use as tractor-trailers, and an M984A4 recovery truck fitted with cranes and winches.
The hybrid drive HEMTT A3 variant is still in development. It claims to offer the same 13-ton cargo capacity and C-130 transportability, with a 20% improvement in fuel economy thanks to diesel-electric propulsion. Its configuration also gives the vehicle an on-board generator that can export 100 kW of military-grade power to power devices, weapons and sensors, or even a small remote installation. The A3’s electrical power potential was attractive to Raytheon’s Mobile Centurion prototype, for instance, which mounts a modified Phalanx radar-guided, electrically-driven 20mm gatling gun turret on the truck in order to shoot down incoming mortars, rockets, and artillery rounds.
The new HEMTT A4 production variants feature a 500 hp Caterpillar C-15 engine, an Allison 4500 SP/5-speed automatic transmission, rated for 600 hp, power-train upgrades to 1,750 pounds of torque, suspension upgrades, and major changes and additions to the cab. The HEMTT A4 shares common cab, parts, and support with the new palletized load system (PLS-A1) truck, reducing the need for separate spares. An improved climate control system that can handle tropical conditions is built into that cab, rather than requiring a retrofit as is the case for the HEMTT A2s.
The new HET A1 features numerous upgrades to the M1070 HET, including a 700-horsepower engine and an Allison 4800SP transmission, as well as improved seats, standard air conditioning and an available 3rd door.
Many of these upgrades actually around the US Army’s Long Term Armor Strategy (LTAS). This LTAS-A armor can be augmented with a standardized, bolt-on LTAS-B kit for greater protection, and an integrated mounting allows fast installation of a protected gunner position (GPK) and machine-gun mount on the cab roof. HEMTT-A4 and their forthcoming companions the PLS-A1 and HET-A1 will come off the assembly line fitted with upgraded suspensions, the engine improvements noted above, different cab designs, and integral composite armor.

Oshkosh Defense’s director, Army Tactical Vehicle Programs Mike Ivy is quoted in AUSA’s April 2008 article as saying that Israeli firm Plasan Sasa played a large role on designing the FHTV LTAS-B armoring kit, but Finmeccanica’s DRS will be the main supplier for the program.
The Army’s new medium FMTV-A1P1 trucks that are currently produced by BAE Systems have their own LTAS-A and LTAS-B kits, extending the LTAS up-armoring approach across the US Army’s entire truck fleet.
LTAS-related changes aren’t the only updates under consideration. A J1939 databus gives the new HEMTT trucks the same kinds of capacity for self-diagnosis and automated troubleshooting that the FMTV medium truck fleet has used so effectively. C4ISR updates are also under consideration. Ivy:
“We are installing in one of our prototype trucks, located at Aberdeen Proving Ground, Md., a number of installation kits for the suite of C4ISR [command, control, communications, computers, intelligence, surveillance and reconnaissance] systems that soldiers expect to see in vehicles today…. That includes things like the Movement Tracking System, GPS, Battle Command System [DID: Blue force Tracker] the whole suite of systems that gives the soldier increased situational awareness. Although there is nothing inherent in the A4 for the Future Combat System-equipped brigade, it could easily be adapted to that, given the right installation kits.” The integration of the installation kits by Oshkosh will allow the Army to test a range of potential C4ISR capabilities for the new platforms.”

Some FHTV-III orders are defined as RECAP orders, however, and won’t be new build machines.
RECAP is part of the US Army’s planned sustainment triad of RESET, RECAP, and Replace. Recapitalization is depot-level maintenance activity that completely rebuilds the vehicles from the frame up, inspecting all parts and replacing worn items, while adding selected enhancements to benefit from more modern parts and technologies.
Under the HEMTT overhaul/ remanufacturing contract, for instance, Oshkosh integrates LED marker lights, two-piece wheels, engine and transmission upgrades, and air ride seats. Ancillary equipment such as cargo bodies, cranes, and fifth wheels are also overhauled and reassembled for use on the remanufactured vehicles. The tires and all electronics, such as wire harnesses, gauges, etc. are replaced with new. The vehicles are reassembled on the same integrated vehicle assembly line as a new truck, with a new “zero hours/zero miles” bumper-to-bumper warranty. All at significant savings over the cost of building a new vehicle.
Contracts and Key Events


All contracts are managed by the U.S. Army’s Tank-automotive and Armaments Command (TACOM) in Warren, MI, unless the entry says otherwise.
Feb 25/09: Oshkosh Defense announces a $477 million delivery order calls for more than 1,350 HEMTT A4s (750 new, 600 RECAP) and more than 1,000 of the Palletized Load System Trailers (PLST) that help with loading and unloading.
This latest order pushes the total value of the FHTV-III contract so far to more than $2.1 billion.
Feb 25/09: Oshkosh Defense unveils its new HET A1 variant at the Association of the United States Army (AUSA) Winter Symposium and Exposition in Fort Lauderdale, FL.
Dec 31/08: Oshkosh Corp. in Oshkosh, WI received a maximum $1.121 billion firm-fixed-price, indefinite-delivery, sole source contract for heavy and medium tactical truck support, if all 9 option years in this 10-year contract are exercised. Under the contract, Oshkosh Defense will supply the DLA with replacement parts to support Oshkosh’s medium and heavy tactical vehicles, which include the US Marines’ Medium Tactical Vehicle Replacement (MTVR) truck, and the Army’s FHTV Heavy Expanded Mobility Tactical Trucks (HEMTT) and Palletized Load Systems (PLS). Oshkosh also supplies replacement parts for other manufacturers’ medium and heavy-payload vehicles.
The first contract order is valued at $17.5 million and is for approximately 2,300 replacement part numbers to support Oshkosh’s tactical vehicles.
This follows the previous 8 year contract, which was structured as a one-year contract with 7 option years, each of which were exercised, that ended in December 2008. There were originally 2 proposals solicited, but only one response. The contract’s base year will end on Dec 31/09, but options could continue this agreement to 2018. The US Defense Logistics Agency’s Defense Supply Center Columbus (DSCC) in Columbus, OH (SPM7LX-09-D-9008) manages these contracts. See also: Oshkosh Defense release.
Dec 22/08: Oshkosh Defense announces a $5 million contract modification to RECAP approximately 30 M1977 Common Bridge Transporters (CBT). Under the modification, Oshkosh Defense will tear down the 10-year-old HEMTT A0-derived CBTs, and upgrade them to HEMTT A2 Load Handling System (LHS) equivalents with computer-controlled engines and transmission systems, as well as a lighter load handling system.

Dec 15/08: Oshkosh Defense announces a $9.4 million contract modification with the U.S. Army Tank-automotive and Armaments Command (TACOM) for continuing research and development of their diesel-electric drive HEMTT A3 variant.
The contract modification will fund additional improvements to the current HEMTT A3 technology demonstrator, by upgrading the vehicle’s engine horsepower and incorporating the U.S. Army’s LTAS armoring strategy. Under this contract, the firm will end up delivering 2 new HEMTT A3 vehicles. One will be provided to the U.S. Army for a 20,000-mile durability test at its Aberdeen Test Center. The 2nd vehicle will be benchmarked for performance against the current HEMTT A2/A4 production vehicles.
Oshkosh Defense President John Stoddart described this contract as: ”...among the first steps that could establish the HEMTT A3 as the Army’s next-generation support vehicle.” Time will tell.
Nov 26/08: Oshkosh Defense announces a $51 million contract with the for more than 660 LTAS-B up-armoring kits for HEMTT A4 trucks. The $51 million contract includes a recent $15 million armor kit contract modification.
The LTAS-A kit is armoring installed at the factory, and delivered with the trucks. The LTAS-B kit is the add-on armor which the HEMMT A4 has been designed from the outset to carry, if necessary. It can be installed by a 2-soldier crew with no special tools, other than the required lifting devices to get the pieces into position.
Since Oshkosh’s Palletized Load System (PLS) A1 trucks will share a common cab with the HEMTT A4 , they will also be able to use these armor kits when they are fielded.
Nov 4/08: Oshkosh Corp. in Oshkosh, WI received the new FHTV-III multi-year contract, which will add more than 6,000 upgraded vehicles to the U.S. Army’s FHTV fleet.
The initial delivery order is a $1.267 billion requirements contract firm-fixed-price contract to buy 2,285 new HEMTT-A4 trucks, 768 HEMTT RECAP trucks, and to upgrade a lower model truck. Work will be performed in Oshkosh, WI with deliveries expected to begin in November 2008 and an estimated completion date of Sept 30/12. One bid was solicited and one bid was received by TACOM in Warren, MI (W56HZV-09-D-0024).
A series of orders that were issued in February and March 2008 raised initial HEMTT A4 orders to 1,745 new and 292 RECAP trucks, with production slated to begin in July 2008. The initial delivery order under FHTV-III will more than double this total. See also Oshkosh release | Defense Update
