ATK and Elbit Systems Conduct Successful Flight Test of GATR from Helicopter

HAIFA, Israel, June 1 /PRNewswire-FirstCall/ -- Elbit Systems Ltd. (Nasdaq:
ESLT) and Alliant Techsystems (NYSE: ATK) announced today that they have
successfully conducted flight tests of the Guided Advanced Tactical Rocket
(GATR).

In a recent demonstration, conducted in Israel, GATR was deployed from a
helicopter using a "lock-on before launch" method to engage an off-boresight
target at a range of approximately three (3) kilometers. ATK and Elbit Systems
validated flight worthiness, safe separation launch, and autonomous laser
designated guided flight through a series of tests. The laser designated
guided flight, launched from a standard 2.75 inch launcher, resulted in a
direct impact on the target.

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 is a low-cost, precision strike
weapon that 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 of
1.5 to 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.
