An MD-10 cargo jet equipped with Northrop Grumman's Guardian anti-missile system took off from Los Angeles International Airport on a commercial flight Tuesday, the company said.
The FedEx flight marked the start of operational testing and evaluation of the laser system designed to defend against shoulder-fired anti-aircraft missiles during takeoffs and landings.
Adapted from military technology, Guardian is designed to detect a missile launch and then direct a laser to the seeker system on the head of the missile and disrupt its guidance signals. The laser is not visible and is eye-safe, the company said.
"For the first time, we will be able to collect valuable logistics data while operating Guardian on aircraft in routine commercial service," said Robert L. DelBoca, vice president and general manager of Northrop Grumman's Defensive Systems Division.
During the current test phase, which concludes in March 2008, nine MD-10s equipped with the Guardian system will be in commercial service. Katie Lamb-Heinz of Northrop Grumman Electronic Systems said all those aircraft will be freighters. The ultimate goal is to defend passenger airliners.
The testing is part of the U.S. Department of Homeland Security's Counter-Man Portable Air Defense Systems program. BAE Systems has also been working for the government on a similar airliner defense system and has successfully tested it.
John Pike, a defense analyst at GlobalSecurity.org, an Alexandria, Va., think tank, suggested that development of the system was the lesser of issues for the airline industry.
"I think the problem is making the numbers work in the sense of figuring out who's going to pay for it," he said.
More than capital costs, airlines are likely to be most concerned about the costs of maintenance and aircraft downtime, he said.
"They've gotten these airliners now (so) that they are just remarkably maintenance-free. They've also gotten these airlines to the point that they've got razor thin margins," he said.
Sen. Barbara Boxer, D-Calif., viewed the plane Monday and said she was encouraged.
"This program is very promising because it's already met the operational testing. Now it's a question of how does it actually work in terms of stresses on the system while the airplane is in operation for several hours," said Boxer, a longtime proponent of equipping planes with anti-missile technology.
Boxer said her first priority is to equip the Civil Reserve Air Fleet, more than 1,000 commercial airplanes operated by airlines that contract with the Pentagon to make military flights during emergencies.
No passenger plane has ever been downed by a shoulder-fired missile outside of a combat zone. But terrorists linked with al-Qaida are believed to have fired two SA-7 missiles that narrowly missed an Israeli passenger jet after it took off from Mombasa, Kenya, in November 2002.
The first commercial flight with the Guardian system followed 16 months of tests on an MD-11, an MD-10 and a Boeing 747 using simulated launches of shoulder-fired missiles.
The Guardian system appears as a pod with eye-like features attached to the belly of the FedEx MD-10, a freight version of what was originally the three-engine widebody DC-10 airliner.
DHS gave Northrop Grumman and BAE Systems $45 million each in 2004 to adapt military defense systems to civilian airliners, requiring improvements because military systems need too much maintenance and mistakenly fire too often.
Adapted from military technology, Guardian is designed to detect a missile launch and then direct a laser to the seeker system on the head of the missile and disrupt its guidance signals.
There have been grave concerns about potential missile attacks on commercial aircraft since terrorists narrowly missed an Israeli aircraft in Kenya in 2002.
