Officials of the Army Space and Missile Defense Command in Huntsville, Ala., announced a $25.2 million contract to Aculight for a 60 kilowatt spectrally combined high-power fiber laser for the High Energy Laser Mobile Demonstrator (HEL MD) -- a joint project of the Army and the Boeing Co. Directed Energy Systems segment in St. Louis.
Army officials had announced their intention to award this three-year sole-source contract to Lockheed Martin Aculight last August. The HEL MD will operate on Army and U.S. Department of Defense test ranges and other outdoor locations. The contract runs through the end of 2016.
In a related action, Army Space and Missile Defense Command officials sent out a request to industry last month to supply an adjustable-power 50-kilowatt laser that with its cooling subsystem can fit on an 8-by-53-foot full-sized flatbed trailer.

Army researchers are asking Aculight experts to capitalize on technology developed under the U.S. military's Robust Electric Laser Initiative (RELI) to increase laser weapons power from the 25 kilowatts demonstrated previously in the RELI program to 60 kilowatts. The HEL MD program is intended to develop a laser weapon to counter airborne threats with lasers of 50 to 100 kilowatts.
Aculight will build and integrate additional RELI 2-kilowatt fiber laser modules identical to those required for the RELI 25-kilowatt laboratory laser, to reach 60 kilowatts output power, Army officials explain.
Aculight experts also will characterize the RELI beam combining fiber array and spectral beam combiner for the higher thermal loading imposed by the increased power.

This project is a continuation of a succession of laser weapons research programs to ratchet-up the power of laser beams to make them strong enough for future generations of laser weapons.
The RELI project builds on laser weapons technologies developed earlier in the Joint High Power Solid State Laser (JHPSSL) and the High Energy Liquid Laser Area Defense System (HELLADS) programs. RELI was a follow-on project to capitalize on technologies developed in JHPSSL and HELLADS.

The JHPSSL and HELLADS projects developed technologies for packaging, cooling, and fire-control capability for future laser weapons. The RELI program has focused on drastic improvements in laser efficiencies, as well as in packaging small enough for deployable laser weapons on tactical aircraft and vehicles.
The RELI program involves Raytheon Space Systems in El Segundo, Calif.; the Boeing Directed Energy Program in Albuquerque N.M., and Lockheed Martin Aculight. Partners on the RELI program are the Army and U.S. Air Force. The U.S. Navy also is expected to get involved.
