Funding has been allocated for the U.S. Navy to study and develop technologies that would reduce jet engine noise as it plans to bring more electronic-warfare aircraft to train on Whidbey Island.

The $675 billion budget for the U.S. Defense Department includes $2 million for the Navy to address jet noise, a contentious topic for local residents.

The Navy released a final environmental impact statement last week on a plan to bring 36 more of the jets known as Growlers for training at the Naval Air Station.

It’s not clear when the jet noise study will begin.
