MUOS-4 Satellite Provides Warfighters
Improved and Secure Communications
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 facility.
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.
