From the U.S. Government Accountability Office, www.gao.gov Transcript for: Testimony: Military Readiness Description: On May 2, 2023, GAO's Diana Maurer testified that the Department of Defense faces several challenges as it works to rebuild and restore readiness across the military while also modernizing its forces. DOD's readiness rebuilding efforts are occurring in a challenging context that requires the department to make difficult decisions regarding how best to address continuing operational demands while preparing for future challenges. Related GAO Works: GAO-23-106673, Military Readiness: Improvement in Some Areas, but Sustainment and Other Challenges Persist Released: May 2023 [ Diana Maurer: ] Broadly speaking, mission capability - can units execute their missions - has declined since 2017. While the Army and Marine Corps improved in the ground domain, we found declines in the sea, air and space domains. For example, only two of 49 aviation systems met their annual mission capable goals. The vast majority missed by over 10%. The F-35 program in particular, suffers from a variety of sustainment woes. Fleet wide mission capable rates have declined every year since 2020, and the Air Force, Navy and Marine Corps face substantial gaps between what it costs to fly the aircraft and what they can afford. The Army needs to improve helicopter safety and address shortfalls in rail support and sealift training that affect readiness and the ability to move to the fight. We found the Navy had nearly $1.8 billion in deferred ship maintenance, mainly in its cruisers and amphibious ships. The Navy also faces a significant crewing shortfall which can harm mission maintenance and safety. Yet even with all these challenges you just heard, the U.S. military is the best in the world. Our work helps keep it that way. GAO will continue to provide independent, hard hitting and constructive reports to help the services and help the Congress carry out its important oversight responsibilities.
