Lockheed Martin Space Systems Company
today announced that its subcontractor, Raytheon Electronic Systems, has
achieved a crucial milestone in the development of the Beam Control/Fire
Control system for the U.S. Air Force’s Airborne Laser (ABL) program. The
Beam Control/Fire Control system will aim and fire a high-energy laser at a
target missile in its boost phase.

Raytheon conducted a “first light” test of the Track Illuminator Laser
(TILL) one week ahead of schedule at its High Energy Laser Center in El
Segundo, Calif. The TILL, one of four critical lasers to the Airborne Laser
Program, is the first solid-state laser to achieve this milestone.

“The ‘first light’ test is significant because the TILL is the heart of the
Beam Control/Fire Control system. This is a brand new technology and the
test proves the design is valid,” said Lockheed Martin ABL Program Manager
Paul Shattuck.

This laser is an integral part of the Beam Control/Fire Control system and
will project rapid, powerful pulses of light on a small section of a
boosting target missile. The light will be reflected back to an extremely
sensitive camera. The reflected light data is interpreted as information
about the target’s speed, elevation and probable point of impact.

“For the ABL program we pushed both sides of the equation — a more
sensitive sensor and a more powerful illuminator laser,” said Shattuck.
“This reduced the development risk because the components can compensate for
each other,” he said.

Raytheon’s test showed that the TILL should have plenty of power to meet the
signal needs of the system. According to Lockheed Martin Chief Systems
Engineer Marya Andrepont, the test is a significant step in proving the
technology. “We were expecting the laser to run for a few seconds, and they
ran it for 30 minutes. I have great confidence that Raytheon will deliver a
laser module that meets our needs,” she said.

Lockheed Martin is part of an industry-government team that is developing
the revolutionary ABL weapon system. Team ABL includes the Air Force,
Boeing, TRW and Lockheed Martin. Boeing is the team lead for weapon system
integration, and supplies the 747-400 freighter aircraft and the battle
management, command and control system. TRW provides the high-energy laser,
which is a chemical-oxygen-iodine laser. Lockheed Martin Space Systems is
designing, developing, and building the Beam Control/Fire Control system,
which will acquire the target, then accurately point and fire the laser with
sufficient energy to destroy a missile while it is still in the boost phase.

The TILL is scheduled to be delivered later this year to Lockheed Martin’s
Beam Control/Fire Control Integration and Test Facility in Sunnyvale, Calif.
The TILL will be integrated with the remainder of the beam transfer optics
early next year, and followed by an end-to-end test of the Beam Control/Fire
Control system.

Once modifications to the 747-400 aircraft are completed at Boeing’s plant
in Wichita, Kan., and the battle management has been installed, the plane
will be flown to Edwards Air Force Base near Lancaster, Calif. The beam
control system and the lasers will be installed there.

Flight tests, expected to begin early next year, will be conducted with each
system separately, then with the system as a whole.

The Airborne Laser will be the world’s first boost-phase defense against
theater ballistic missiles of the type that were used against U.S. troops
during the Gulf War. Unlike ground-based systems, ABL will operate from
hundreds of miles away and will be able to lock onto enemy missiles shortly
after they lift off. ABL will fire an intense beam of heat that causes the
missile’s skin to rupture and its fuel to gush and explode. Since the
missiles are still rising, the warheads will fall onto or near the enemy’s
