TRAILER DEVELOPMENT

Abstract

The Semi-Trailer Low-Bed (STLB) is a 25-ton payload capacity semi-trailer with a fixed goose neck, step deck, and rear loading ramps. The STLB is interoperable with a variety of trucks residing across the U.S. Army equipment and will be introduced into a theater of operations to transport construction equipment (CE) employed by U.S. Army Engineers to execute horizontal and vertical construction projects in support of U.S. Military or other national goals and objectives. The STLB is employed to transport CE, miscellaneous equipment, disabled equipment, Class IV (construction materials), and logistical provisions. The STLB supports units in the execution of the following tasks: expand the lodgment, construction/upgrade/rehabilitation and maintenance of main supply routes (MSR), alternate supply routes (ASR), logistical facilities, bituminous roads, helipads, airfields, landing strips, motor pools, parking areas, etc. These types of facilities are required for sustainment operations during decisive action operations. The STLB will also be used during routine exercises/deployments, disaster relief, and other nation building operations. The STLB will be capable of supporting mobility, counter mobility, survivability, counter improvised and sustainment needs and all applicable North Atlantic Treaty Organization (NATO) interoperability criteria. The Heavy Equipment Transporter System (HETS) is comprised of a M1070A1 Tractor and M1000 Trailer for transport, recovery and evacuation of heavy, oversized combat equipment such as the M1A1 Abrams main battle tank (MBT) and M88 recovery vehicle or similar loads. The current HETS has two capability gaps: Payload and Road Network Accessibility. The current HETS is not capable of transporting or loading/unloading the heaviest combat platform in the ABCT since it exceeds the HETS rated payload of 70 tons (U.S.). Road Network Accessibility of the current HETS is restricted due to exceeding axle load limits CONUS/OCONUS, which prevents the HETS from obtaining road permits. In the near term, the interim solution is to modify current HETS tractors and procure new HETS trailers. The long term solution is the Enhanced Heavy Equipment Transporter System (EHETS) that will address these capability gaps. The near term interim solution is in response to a United States Army Europe (USAREUR) Operational Needs Statement (ONS# 17-22207) for Heavy Equipment Transporter Systems with deliveries beginning the first quarter of FY2020. The USAREUR HETS ONS solution will be capable of carrying 78.5 Tons of payload while achieving host country road permits at a reduced weight of 75 tons. The recommended course of action for satisfying the ONS is to utilize a modified version of the M1070A1 tractor combined with a commercial 8-axle trailer. Per the 1 DEC 17 Army Requirements Oversight Council (AROC) decision, this trailer will be capable of carrying 85 tons. The AROC also directed an additional modification to the tractor that will allow it to achieve an ultimate carrying capacity of 85 tons. The Enhanced Heavy Equipment Transporter System (EHETS) is a force protected tractor and trailer to operationally move and load/unload the heaviest combat platform in the ABCT. EHETS will be capable of transporting at a higher rated payload and will self-load/unload heavy and outsized equipment such as the Abrams SEPv2 and SEPv3, which currently exceeds the existing Heavy Equipment Transporter System rated capacity of 70-tons (U.S.), while achieving road network accessibility (e.g. road permits) and mobility on primary and secondary roads. The Heavy Dump Truck (HDT) supports construction projects by loading, transporting and dumping payloads of sand and gravel aggregates, crushed rock, hot asphalt mixes, earth, clay, rubble, large boulders and other materials up to gross vehicle weight rating to job sites under world-wide climatic conditions. The HDT also serves as a quarry truck for the quick transport of bulk raw earth material to and from the crushing, screening and washing plant and the asphalt mixing plant. The HDT also serves as a transportation asset for organizational equipment. The HDT is Long Term Armor Strategy (LTAS) compliant with MRAP 1.1 underbody protection. The armor solution is developed concurrently with the production of armor capable HDTs. Funding supports modernization of the current Tactical Wheeled Vehicle fleets by investigating technology insertions including, but not limited to: condition based maintenance, vetronics, Victory Architecture, autonomous operations and other emerging technologies. Funding also supports developing initial prototypes to enable refinement of Operational Requirements and early user feedback to support future sustainment and operational movement operating concepts There is no FY 2020 funding for Project E50 / TRAILER DEVELOPMENT. The above activities were funded with Project E50 funds prior to FY 2020. In accordance with Section 1815 of the FY 2008 National Defense Authorization Act (P.L. 110-181), this item is necessary for use by the active and reserve components of the Armed Forces for homeland defense missions, domestic emergency responses, and providing military support to civil authorities.
