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 truck tractors residing across the U.S. Army equipment inventory. The STLB 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 current 25-ton semi-trailers were manufactured in the 1968 to 1975 timeframe with an average age of 38 to 45 years. The Economic Useful Life (EUL) of the current trailer is 30-years. The existing semi-trailers have far exceeded their EUL and are plagued with problems requiring constant maintenance attention. Repair parts are extremely difficult or impossible to obtain due to inactivity or deletion from the inventory. The burdensome conditions created from the age and maintenance nuisance of the current fleet of 25-ton semi-trailers has placed them in the liability category as opposed to the valued asset category required of units relying on their service. FY17 funds will be used to start the requirements analysis process through the use of the Dynamic Object Orientated Requirements System (DOORS), as well as, perform a market survey and Whole Systems Trade Analysis (WSTA). The efforts are needed to meet a user approved requirement gap in the Heavy Tactical Trailer fleet as identified in the 25-ton STLB Capability Production Document (CPD) approved 10 July 2014.
