Army Modernization: Steps Needed to Ensure Army Futures Command Fully Applies Leading Practices, Report to the Committee on Armed Services, House of Representatives [open pdf - 3MB]
From the Highlights: "In order for the Army to maintain its technological edge over potential adversaries, it plans to invest in near-and long-term modernization efforts. However, the Army has struggled with modernization initiatives in the past. For example, the Future Combat System was canceled after a cost of $21 billion and delivery of few new capabilities. The National Defense Authorization Act for Fiscal Year 2018 included a provision for GAO [Government Accountability Office] to report on the Army's modernization strategy. This report assesses (1) the status of the Army's near- and long-term modernization efforts; and (2) the extent to which the Army has applied leading practices to these efforts."
