SES Selects Orbital ATK to Build SES-16/GovSat Satellite for Mid-2017 Delivery

Third GEOStar-3 Spacecraft Ordered Since 2014 Introduction

DULLES, Va.Feb. 16, 2015-- Orbital ATK, Inc. (NYSE:OA), a global leader in aerospace and defense technologies, announced today it received a contract to build a communications satellite for LuxGovSat, a newly created joint venture between SES and the Luxembourg government. SES-16/GovSat will be used to provide military satellite bandwidth to governments and institutions. The Luxembourg government has pre-committed to a significant amount of capacity in support of its NATO obligations.

Based on Orbital ATK s recently introduced GEOStar-3 satellite platform, SES-16/GovSat is a multi-mission satellite using dedicated military frequencies (X-band and military Ka-band) to provide high-powered and fully steerable spot beams for multiple government-specific missions. It is Orbital ATK s 40th GEOStar satellite sale, the third GEOStar-3 satellite purchased, and seventh GEOStar satellite to be built for SES.

SES is one of the world s most prominent satellite operators and this contract demonstrates a continued confidence in our GEOStar product line. As a customer-focused company known for innovation, reliability and affordability, we are pleased to provide LuxGovSat with a high-quality satellite that will meet expectations in cost, schedule and performance, said Chris Richmond, VP and GM of the Commercial Satellite Division at Orbital ATK s Space Systems Group. Based on our exceptional record of delivering flight-proven satellites on time and on budget, Orbital ATK continues to be a partner that SES and the Government of Luxembourg can count on.

Orbital ATK s GEOStar satellite platform can accommodate all types of commercial communications payloads and is compatible with all major commercial launchers. The GEOStar design is optimized for satellite missions requiring up to eight kilowatts of payload power.

The company also offers a hybrid electric propulsion GEOStar-3 design that provides the benefits of higher power/higher payload capability while still maintaining advantageous launch costs.

Martin Halliwell, Chief Technology Officer of SES, commented, The joint procurement of SES-16/GovSat opens a new chapter in the strategically important government business vertical and in the cooperation between SES and the Luxembourg government. SES-16/GovSat will ensure flexibility for the ever-changing missions of governments and institutions in the security, defense and civil arena and will allow for the deployment of integrated and smart end-to-end managed solutions for these demanding customers.

SES-16/GovSat will be designed, manufactured and tested at Orbital ATK s satellite manufacturing facility in Dulles, Virginia. It is slated for delivery in mid-2017. Once in orbit, it will be positioned on the European geostationary orbit arc with coverage areas over Europe, the Middle East and Africa. It will have a service life of 15 years.
