The Defense Department’s Inspector General will be taking a close look at the glaring readiness shortcomings at Military Sealift Command that were the subject of another government report last summer.

August’s Government Accountability Office report revealed a spike in readiness issues over the past five years for ships that provide critical at-sea resupplies of fuel, ammo and other essentials.

The 29 ships of the resupply fleet experienced 69 equipment casualties in 2012 that limited at-sea mission capability, according to the GAO. In 2016, that number rose to 122.

“Our objective is to determine whether the Military Sealift Command ensured that prepositioning ships received required maintenance,” according to a Dec. 26 DoD Inspector General release.

The investigation will be conducted at the headquarters of Military Sealift Command in Naval Station Norfolk, according to the release.
