United Launch Alliance
Successfully Launches NROL-82 Mission to Support
National Security
April 26, 2021
A United Launch Alliance
(ULA) Delta IV Heavy launch vehicle carrying the
NROL-82 mission for the National Reconnaissance
Office (NRO) lifted off from Space Launch
Complex-6 on April 26 at 1:47 p.m. PDT. To date
ULA has launched 143 times with 100 percent
mission success.
“The unmatched power of the
Delta IV Heavy again demonstrated its role as
the nation’s proven heavy lift vehicle precisely
delivering this critical NRO asset to its
intended orbit,” said Gary Wentz, ULA vice
president of Government and Commercial Programs.
“We are honored to support National Security
space and thank our mission partners for their
continued trust and teamwork.”
The Delta IV Heavy is
recognized for delivering high-priority missions
for the U.S. Space Force, NRO and NASA. The
vehicle also launched NASA's Orion capsule on
its first orbital test flight and sent the
Parker Solar Probe on its journey to unlock the
mysteries of the sun.
This was the 42nd launch of
the Delta IV rocket, the 13th in the Heavy
configuration and ULA’s 31st launch with the
NRO.
This Delta IV Heavy was
comprised of three common core boosters each
powered by an Aerojet Rocketdyne (AR) RS-68A
liquid hydrogen/liquid oxygen engine, producing
a combined total of more than 2.1 million pounds
of thrust. The second stage was powered by an AR
RL10B-2 liquid hydrogen/liquid oxygen engine.
