By the time of America's entry into World War II, the depot was a center for storage and repair for bombers as well as a variety of other aircraft.
The base continued to operate after the war, but was recommended for closure in 1995 by Congress's Base Realignment and Closure (BRAC) commission. A privatization plan was put into play after the base closed due to the BRAC commission, in an attempt to preserve the 8,700 jobs that had been provided by the former base. One of the problems preventing private development is the environmental damage caused by the base during its years of operation. The base is widely-regarded as one of the most polluted military bases in the US. The area was placed on the National Priorities List of the United States Environmental Protection Agency.
