Story highlights The aircraft, an ATR 42-500, was purchased for a program called "Global Discovery"

Modifications over the last seven years has cost the Defense Department four times the anticipated amount of $22 million

Washington (CNN) The Drug Enforcement Administration and the Department of Defense spent more than $86 million on an aircraft for counter narcotics efforts in Afghanistan that has "never actually flown in Afghanistan," according to a Department of Justice inspector general report.

The aircraft, an ATR 42-500, was purchased for a program called "Global Discovery." Over the last seven years, it was outfitted with surveillance equipment and modified to conduct operations in a combat zone, which cost the Pentagon four times the anticipated $22 million. And of as March, the aircraft was inoperable and resting on jacks, said the report , which was issued on Wednesday.

Though the DEA awarded a contract to purchase the aircraft at a cost $3 million more than it estimated, most of the misused funds were used in retrofitting the aircraft. For example, by October 2014, more than $65 million was spent on the aircraft's modifications. But those modifications required that an additional $6 million more be spent to repair damages that which occurred while outfitting it with surveillance and communications equipment.

Additionally, the report found that almost $2 million was spent to modify a hangar for the aircraft, also known as ATR 500, but the aircraft was never housed there, nor will it, as the DEA ceased aviation operations from Afghanistan in July 2015.

Flight logs revealed that only 14% of the missions flown by the DEA in Afghanistan between October 2011 and February 2015 were for reconnaissance, surveillance or intelligence, according to the inspector general. The rest of the flight missions were for "transporting personnel and equipment."
