Cost-Benefit Analysis (CBA) of the Total Integrated Engine Revitalization (TIGER) Condition-Based Overhaul (CBO) Process for the M1 Abrams AGT 1500 Turbine Engine at the Army Depot Level of Maintenance

Abstract

The M1 Abrams is one of the finest land combat vehicles in history and has been the backbone of our nation's ground combat strategy since its introduction in the 1980s. Initially intended to be in service until 2027, the Department of Defense (DoD) has extended the M1's role to the year 2050 increasing the operations and support (O&S) cost burden associated with this system. The M1's engine, the Honeywell AGT1500, accounts for over 60% of that system's O&S cost. As a result, ways to reduce the cost of maintaining the engine (as well as improve its durability) have been the focus of TACOM and PM Abrams. Honeywell's Total Integrated Engine Revitalization (TIGER) program attacks this problem from several directions. Condition-based Overhaul (CBO) is one strategy designed to reduce the cost of overhauling the engine at Anniston Army Depot (ANAD). Building on existing durability and process improvements, Honeywell and ANAD have formulated a process that utilizes engine usage data and operating hours to direct a tailored overhaul of each engine. This cost-benefit analysis (CBA) focuses on quantifying the costs and benefits of this change.
