The Navy has sent the USS Carl Vinson carrying EA-18G Growlers based out of Naval Air Station Whidbey Island to assist in air strikes against the Islamic State in Iraq and the Levant.

The Carl Vinson strike group, which includes Electronic Attack Squadron (VAQ) 139, replaces the USS George H.W. Bush carrier strike group which has been deployed since Feb. 15, according to the Navy.

Whidbey Island’s VAQ 134, flying the EA-6B Prowlers, have been a part of the departing strike group, and their involvement will be the Navy’s final Prowler deployment.

“This is the final Navy EA-6B Prowler deployment, and that, despite its age compared to the modern EA-18G Growler, the old Prowler, thanks to its dedicated maintainers and aircrew, is proving itself right up to the end,” according to Lt. Joseph Hontz, U.S. 5th Fleet spokesman.

The carrier’s air wing amassed 32,611 flight hours, 12,548 total sorties and 9,752 traps, supporting Operation Enduring Freedom in Afghanistan and Operation Inherent Resolve against ISIS and terrorists in Iraq and Syria, according to the Navy.

The Navy has said in previous news releases that the electronic attack squadrons are assisting in air strikes performed by the U.S. Air Force’s F/A-18 Hornet and Super Hornet aircraft, and that roughly 74 percent of the attacks are by the Air Force.

“The sailors who man our ships and squadrons should be extremely proud of what we, as a team, accomplished while deployed to the 5th Fleet,” said Rear Adm. DeWolfe Miller in a Navy news release. “Carl Vinson Strike Group has the watch and their presence, like ours, will enhance regional stability and make a difference in the fight against terrorism.”

Upon return VAQ 134 will begin its transition to the Growler, which will complete the Navy-wide transition in 2015.

Prowlers will still be flown by the Marine Corps squadrons.
