Navy: Half the Carrier Fleet Tied Up In Maintenance, Other 5 Strained To Meet Demands
"USS Gerald R. Ford (CVN-78), which will commission next year but not be operationally available until 2021 due to first-in-class test and evaluation."
This statement is hard to stomach at face value that 5 years is required between commissioning and deployment. In contrast, the USS Nimitz was commissioned in 5/75 and its first deployment was 7/76, just 14 months. GAO had previously reported that substantial fit out work are planned post commissioning because the USS Ford overspent against construction budget and had to defer work to get around budget cap and accountability issues.
