Current FSG President Ron Grabe to Continue in Senior Advisory Role
DULLES, Va.Jun. 11, 2015--
Orbital ATK, Inc. (NYSE: OA), a global leader in aerospace and defense
technologies, today announced that it has named Mr. Scott Lehr as
President of the company s Flight Systems Group (FSG) effective 1 July
2015, succeeding Mr. Ron Grabe who will continue in a senior advisory
capacity with the group. Mr. Lehr has served as Senior Vice President
and Mr. Grabe s Deputy since the completion of the merger between
Orbital Sciences Corporation and Alliant Techsystems (ATK) in February
2015. Prior to the merger, Mr. Lehr served with ATK and a predecessor
company for 31 years, most recently as General Manager of ATK s
Commercial and Defense Propulsion Systems Division.
I am very confident in Scott s ability to lead our Flight Systems
Group, said Mr. David W. Thompson, President and Chief Executive
Officer of Orbital ATK. Over the past year, he played a major role in
our merger, teaming with Ron Grabe to plan and execute the integration
process that resulted in a seamless transition to the combined
operations of the new FSG. Scott s many years of distinguished service
at ATK demonstrate he is a strong and capable leader with a track record
of success in managing and growing large organizations.
Commenting on Mr. Grabe s service with the company and exemplary career,
Mr. Thompson added, I am also deeply grateful to Ron for helping lead
the company through the merger transition and integration process, as
well as for his 21 years of service with Orbital before the merger. Ron
has not only served our company with distinction but our nation as well.
For these many years, Orbital, and now Orbital ATK, has benefited from
his extraordinary leadership skills developed through a remarkable
career as a decorated Air Force combat and test pilot, a four-time NASA
astronaut, and a business executive.
Orbital ATK's Flight Systems Group provides systems and products that
span the space launch, strategic missile and missile defense, and
aerospace structures markets. The group is a premier producer of solid
rocket propulsion systems and specialty energetic products; a leading
provider of small- and medium-class space launch vehicles for civil,
defense and commercial missions; a major supplier of interceptor
boosters and target vehicles for missile defense; and a world class
manufacturer of composite primary and secondary structures for
commercial and military aircraft and launch vehicles.
Remarking on his new role, Mr. Lehr stated, I am humbled by the
promotion considering the depth of talent we have in the group, the
commitments we make to our customers, the many opportunities we have for
growth in our markets, and the significant legacy left by my
predecessor. It has been my honor to work with Ron through the merger
process and I look forward to his wise counsel as he assumes a senior
advisory role with the group. His accomplishments and integrity will
serve as inspiration for me in the years ahead.
Mr. Grabe added, I look forward to assisting Scott in his new position
and have the highest confidence in his leadership to move the Flight
Systems Group forward. I know that I am turning over the lead role to
someone who has the experience and vision to guide FSG through the
opportunities and challenges of the future.
