MUOS-4 Satellite Provides Warfighters Improved and Secure
DULLES, Va.Sep. 2, 2015--
Orbital ATK, Inc. (NYSE: OA), a global leader in aerospace and defense
technologies, provided critical hardware for today s United Launch
Alliance Atlas V launch from Cape Canaveral Air Force Station, Florida.
The company contributed products on the fourth satellite in the U.S.
Navy's Mobile User Objective System (MUOS), designated MUOS-4, and the
United Launch Alliance (ULA) Atlas V launch vehicle.
MUOS is the next generation in narrowband tactical satellite
communications systems. The MUOS constellation, for which Lockheed
Martin Space Systems (NYSE: LM) is the prime contractor, will provide
mobile warfighters with significantly improved and secure communications.
It was great to see another successful ULA Atlas V launch that flew
Orbital ATK-produced structures and components for both the launch
vehicle and satellite, said Scott Lehr, President of Orbital ATK s
Flight Systems Group. Once again, this is a really good example of the
breadth of our product line and the critical role we play in almost
every EELV launch.
Using advanced fiber placement manufacturing and automated inspection
techniques, Orbital ATK produced three components for the ULA Atlas V
vehicle, including the 10-foot diameter composite heat shield that
provides essential protection to the first stage engine, the Centaur
Interstage Adapter (CISA) that houses the second stage engine and the
boattail that adapts from the core vehicle to the five-meter diameter
fairing. The structures were fabricated by Orbital ATK at its Iuka,
Mississippi, facility. This is the 56th Atlas V launch using
Orbital ATK-built composite structures.
The ULA Atlas V rocket flew in the 551 vehicle configuration with a
five-meter fairing, five solid rocket boosters and a single-engine
Centaur upper stage. Orbital ATK manufactured the Reaction Control
System propellant tank for the ULA Atlas V at its Commerce, California
This flight marked the 21st successful flight of the Orbital
ATK retro motors. Eight of these solid motors provided thrust for
separation of the spent first stage. The ULA Atlas V retrorocket is
built at Orbital ATK's Elkton, Maryland, facility.
For the MUOS-4 satellite, Orbital ATK provided multiple components and
structures from the following company locations: San Diego, Goleta and
Commerce, California; Magna, Utah; and Beltsville, Maryland.
The MUOS-4 is the fourth satellite in the Navy s planned five-satellite
MUOS constellation. Once the constellation is complete, MUOS satellites
will provide a 16x increase in number of accesses over the current Ultra
High Frequency (UHF) satellite system requirement. MUOS-1, MUOS-2 and
MUOS-3 launched respectively in 2012, 2013 and January 2015, and are
already providing high-quality voice communications. MUOS-5 is expected
to launch in 2016.
