Electronic Attack Squadron 138 (VAQ-138), also known as the "Yellow Jackets", is an expeditionary EA-18G Growler squadron of the United States Navy based at Naval Air Station Whidbey Island, Washington.

The Boeing EA-18G Growler is an American carrier-based electronic warfare aircraft, a specialized version of the two-seat Boeing F/A-18F Super Hornet. The EA-18G replaced the Northrop Grumman EA-6B Prowlers in service with the United States Navy. The Growler's electronic warfare capability is primarily provided by Northrop Grumman. The EA-18G began production in 2007 and entered operational service with the US Navy in late 2009. Australia has also purchased thirteen EA-18Gs, which entered service with the Royal Australian Air Force in 2017.
