United
Launch Alliance Successfully Launches WGS-7
July 23, 2015
A United Launch Alliance (ULA) Delta
IV rocket successfully launched the seventh Wideband Global
SATCOM (WGS) communications satellite for the U.S. Air Force at
8:07 p.m. EDT today from Space
Launch Complex-37. This is ULA's seventh launch in 2015 and the
second successful ULA launch in just eight days. Today marks
ULA's 98th successful one-at-a-time launch since the company was
formed in December 2006.
"Kudos to the Air Force and all of our
mission partners on today's successful launch and orbital
delivery of the WGS-7 satellite. The ULA team is honored to work
with these premier U.S. government and industry mission
teammates and to contribute to the WGS enhanced communications
capabilities to the warfighter," said
Jim Sponnick, ULA vice
president, Atlas and Delta Programs. "The team continues to
emphasize reliability, and one launch at a time focus on mission
success to meet our customer's needs."
This mission was launched aboard a
Delta IV Medium-plus (5,4) configuration Evolved Expendable
Launch Vehicle (EELV) using a single ULA common booster core
powered by an Aerojet Rocketdyne RS-68A main engine, along with
four Orbital ATK GEM-60 solid rocket motors. The upper stage was
powered by an Aerojet Rocketdyne RL10B-2 engine with the
satellite encapsulated in a five-meter-diameter composite
payload fairing.
Wideband Global SATCOM provides
anytime, anywhere communication for the warfighter through
broadcast, multicast and point to point connections. WGS
provides essential communications services, allowing Combatant
Commanders to exert command and control of their tactical
forces, from peace time to military operations. WGS is the only
military satellite communications system that can support
simultaneous X and Ka band communications.
ULA's next launch is the Atlas V
MUOS-4 mission for the United States Navy, scheduled for
August 31 from Space Launch
Complex-41 from Cape Canaveral Air Force Station,
Florida.
The EELV program was established by
the United States Air Force to provide assured access to space
for Department of Defense and other government payloads. The
commercially developed EELV program supports the full range of
government mission requirements, while delivering on schedule
and providing significant cost savings over the heritage launch
systems.
With more than a century of combined
heritage, United Launch Alliance is the nation's most
experienced and reliable launch service provider. ULA has
successfully delivered more than 95 satellites to orbit that
provide critical capabilities for troops in the field, aid
meteorologists in tracking severe weather, enable personal
device-based GPS navigation and unlock the mysteries of our
solar system.
