GAO reports Abrams maintenance costs rising
GAO reports a $181.3 million fleet-wide maintenance cost increase between FY2015 and FY2023, with per-vehicle maintenance costs nearly doubling. Availability was below the Army goal. The public summary does not provide an Abrams-specific readiness percentage or the dollar basis for this comparison; neither is inferred.
