Electronic Attack Squadron 129 (VAQ-129) is the United States Navy's only EA-18G Growler training squadron. Known as the "Vikings", they are a Fleet Replacement Squadron, or FRS, and are charged with training all EA-18G aviators and developing standard operating procedures for the maintenance and operation of the aircraft. The squadron is permanently stationed at Naval Air Station Whidbey Island, in Puget Sound, 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.
