Military Readiness: Department of Defense Domain Readiness Varied from Fiscal Year 2017 through Fiscal Year 2019

Report Date:



Nearly 2 decades of conflict has degraded military readiness at a time when the National Defense Strategy calls for preparedness for great-power competition. The strategy states that DOD should be ready to operate in all warfighting domains - ground, sea, air, space, and cyber. To assess readiness over time, the John S. McCain National Defense Authorization Act for Fiscal Year 2019 included a provision that GAO report annually through 2022--using 2017 as a baseline--on the readiness of the military in the ground, sea, air, space, and cyber domains. This report describes (1) the extent to which DOD has established a plan with goals and metrics for readiness recovery and (2) how readiness has changed from fiscal year 2017 through fiscal year 2019 in each domain. This report is a public version of information reported in classified reports that GAO issued from August 2018 through January 2020, with information GAO has updated as appropriate and the most current data available for underlying reports on which this report is based. Information DOD deemed classified has been omitted. GAO reviewed readiness recovery plans and, in consultation with DOD, selected nongeneralizable samples of forces for each domain. GAO grouped the forces into mission areas and analyzed readiness data.
