English: Naval Air Station Whidbey Island, Wash. (May 18, 2004) - Two EA-6B Prowlers assigned to the "Cougars" of Electronic Attack Squadron One Three Nine (VAQ-139) fly in formation around Washington's Mount Rainier during a routine training mission. VAQ-139 is homeported at Naval Air Station Whidbey Island, Wash. and will soon be deploying to support Operation Iraqi Freedom. The EA-6B's primary mission is to protect fleet surface units and other aircraft by jamming hostile radars and communications. With its jamming capabilities together with AGM-88 High-Speed Anti-Radiation Missiles (HARM), the Prowler a unique national asset that can be deployed from land bases and aircraft carriers. Its ability to monitor the electromagnetic spectrum and actively deny an adversary's use of radar and communications is unmatched by any airborne platform worldwide. At 14,410 feet, Mount Rainier is the most prominent peak in the Cascade Range. It dominates the landscape of a large part of western Washington State. The mountain stands nearly three miles higher than the lowlands to the west and one and one-half miles higher than the adjacent mountains. It is an active volcano that last erupted approximately 150 years ago. U.S. Navy photo by Photographer's Mate 2nd Class Michael Watkins (RELEASED)
