Madison residents, especially those on the East Side, have often complained about the roar of commercial and military jets. The county airport and the Air National Guard have said they take steps to minimize noise.

The governor said he didn’t expect F-35s to produce substantially more or louder noise around Truax Field.

“As someone who lives in earshot of this, I’ve got to tell you, it’s not that frequent,” Walker said. The Executive Residence in Maple Bluff is about 7 miles southwest of Truax.

Walker also said the fighter jets and $20 million in federal dollars to upgrade the base would be like “pouring jet fuel” on the Madison-area economy.

Walker said no taxpayer money was offered to persuade the Air Force, and he would not say how much money was spent lobbying. He said the lobbying was largely done by the state’s federal delegation.

The Chamber of Commerce contracted with two advisers with military expertise in Washington, D.C., and raised $100,000 for its efforts to bring the fighters to Madison in conjunction with the Badger Air Community Council.

The Air Force on Thursday announced another new F-35 site, Dannelly Field in Montgomery, Alabama.
