Navy Takes Aim at Roadside Bombs Associated Press | June 12, 2007
The EA-6B Prowler is thought to be one of the most effective The aircraft debuted at the tail end of These days the Prowler focuses its jammers on smaller signals: those of mobile phones and garage door openers that are used to trigger roadside bombs in Iraq, said U.S. Navy Capt. David Woods, 49, of Ogden, Utah. Often, it's hard to prove that a roadside bomb failed to explode because of Prowler jamming signals, Woods said. Still, he's confident the plane is making a difference against the bombs, which the military calls improvised explosive devices, or IEDs. "When it's flying we have greater success and fewer IEDs going off," Woods said. "It's kind of an insurance policy." Woods, the commander of Carrier Air Wing Eleven and one of the Navy's most experienced Prowler pilots, says few people understand the EA-6B's mission, which is to control the electromagnetic spectrum so allies can use it - but not enemies. The Prowler and its electronic warfare system is so valuable it has never been exported - even to close allies. Details about the training of crew members are secret. The Prowler is a homely plane, hung with torpedo-shaped pods and covered in tumor-like bumps packed with a bewildering array of computers, transmitters, antennae and receivers that can analyze and block ground transmissions. A sinister-looking prong protruding from its nose is a refueling nozzle. The EA-6B's bulbous nose cradles a crew of four: a pilot and three electronic countermeasures officers who operate the jamming gear. Outside experts say the Prowler remains the world's most effective electronic warfare aircraft, but the aging Still, the Pentagon considers the Prowler critical enough to ensure no Another two land-based Prowler squadrons are in In 1999, Serb air defenses shot down an Air Force F-117 stealth fighter probably because it strayed too far from the jamming beam of its Prowler escort, said Loren Thompson, a military analyst with the Washington-based Lexington Institute. On the Nimitz, which operated inside the Over The Prowlers fly between 20,000 and 30,000 feet, Woods said, steering invisible waves of electromagnetic signals over areas where insurgent bombs may be waiting for According to outside experts, receivers inside the Prowler's tail collect radio signals from the ground, which are analyzed by an on-board computer. As threats are identified, the plane's crew floods the area with electromagnetic energy that blocks the signal. The plane's computer is loaded with a "threat library" of hostile signals, which are used to match those on the ground. The jammers can block transmissions across wide range of frequencies, everything from TV and radio signals to mobile phones and the Internet. But its jamming gear has no effect on bombs that are hard-wired to their triggers, Woods said. The Pentagon is spending $9 billion to replace the Prowler with 90 Boeing F/A-18 fighters outfitted with electronic warfare gear. The first two, known as the EA-18G Growler, are already being tested. The first Growlers are supposed to begin service by 2009 and replace the carrier-based Prowler squadrons by 2013. The job is expected to eventually be taken over by unmanned planes. Woods is among a rare breed with more than 1,000 aircraft carrier landings - nearly all with the Prowler. He says he'll miss the plane he's been flying since 1984. "It's like an old girlfriend or your first car," he said, pointing to a photo of the plane on the wall of his quarters on the Nimitz. "There are things about it you just can't replace. |
ABOARD THE USS NIMITZ IN THE GULF - A secret aircraft that debuted in Vietnam and usually protects U.S. fighter jets is getting a new type of task over Iraq - trying to stop the scourge of roadside bombs by jamming ground signals from mobile phones and garage door openers.
