ATK AND ELBIT SYSTEMS CONDUCT

SUCCESSFUL FLIGHT TEST OF GATR FROM OH-58D KIOWA WARRIOR HELICOPTER

RESULTS DEMONSTRATE LOW-COST, RAPID DEVELOPMENT OF AFFORDABLE PRECISION

Haifa, Israel, December 2, 2009 - Elbit Systems Ltd. (NASDAQ: ESLT) and Alliant Techsystems (NYSE: ATK) have successfully conducted flight tests of the Guided Advanced Tactical Rocket (GATR) from a U.S. Army rotary-wing helicopter: the OH-58D Kiowa Warrior.

The tests took place during a recent U.S. Aviation Applied Technology Directorate (AATD)demonstration, conducted at Eglin Air Force Base in Florida. GATR was fired from a Kiowa Warrior helicopter using “lock-on before launch” to engage targets exceeding five (5) kilometers. The multiple laser-designated guided test flights, launched from a standard 2.75-inch launcher, resulted in direct impacts on all targets. The pilot of the OH-58 was able to confirm lock-on of the GATR prior to launch.

“The cooperation with ATK, and the synergy from both companies’ highly advanced technologies, enabled us to bring to market cutting edge, precise munitions to answer the requirements of today’s combat arena.” said Ran Hellerstein, Co-General Manager of Elbit Systems’ Aerospace Division.

“ATK has successfully positioned itself as a partner of choice, and by teaming with Elbit Systems; we have rapidly developed and deployed a low-cost precision system to meet our customers’ needs,” said Mark DeYoung, ATK Senior Vice President and President Armament Systems.

Originally announced in July 2008, GATR benefits from a robust design, which combines combat-proven performance, a minimum smoke signature and the reliability of an ATK-produced propulsion system, similar to a system employed on millions of rockets produced for the United States Army. GATR contains a guidance and control system built with the experience of Elbit Systems’ heritage in high-performance laser seekers for the United States and international customers. It employs advanced acquisition, tracking and guidance algorithms to achieve one-meter accuracy against stationary and moving targets. In its tactical configuration, GATR will incorporate an Insensitive Munitions (IM) rocket motor and a family of IM warheads to include blast/fragmentation and penetration. GATR minimizes collateral damage, while providing stand-off deployment against a wide array of target sets.

GATR supports lock-on before or after launch as well as autonomous or remote laser designation. The system can be deployed against targets at ranges exceeding 8 kilometers from fixed and rotary-wing aircraft.It is compatible with existing 2.75”/70mm launcher hardware. GATR will be particularly effective in urban areas or against targets where a low collateral damage solution is required. The GATR system fills the gap between larger, more expensive guided missiles and the current family of unguided rockets.
