To be fair, the two OV-10G+ testbeds sent to Iraq for evaluation required very expensive overhauls and modernization; they also had parts availability problems. As is the case with so many things like this, the numbers indicated that would cost less money to build new ones than uprating hypothetically stored units. It cost $20 million to refurbish just the two test aircraft and they were already flyable at the time they were taken back into service.
2006: Federal Government unloaded 20 OV-10 Broncos for as little as $2,400.
