ARLINGTON, Va., Jan. 8, 2013 /PRNewswire/ --ATK's (NYSE: ATK) Space
Components Division in Goleta, Calif. signed a contract with Israel Aerospace
Industries (IAI) to provide the solar array to power the AMOS-6 (Affordable
Modular Optimized Satellite). The solar array is ATK's heritage Planar
Unfolding Modular Array (PUMA), which has demonstrated low non-recurring
engineering cost (NRE), low risk, ease of satellite implementation, and
100-percent flight success performance on more than 50 solar array wings

With variants having been in continuous production for more than ten years for
programs like Boeing's GPS-IIF satellites and Orbital's STAR2 geosynchronous
(GEO) satellites, ATK's PUMA array platform was a natural fit for IAI's
high-power commercial needs.

"We are pleased with this award for our modular PUMA solar array platform,
which was adapted to meet the required 10.3 kW end-of-life power for the
AMOS-6 communication satellite," said David Shanahan, vice president and
general manager, ATK Space Components Division. "Our tremendous success rate
is a record we are proud of."

The contract calls for delivery of ATK's solar array in 18 months, with the
option to perform work on the AMOS-7 solar array should IAI receive the
follow-on contract from Spacecom in Israel.
