Company's DSU-33 Sensor Enables Precise Detonation and Maximum Effect
DULLES, Va.Jun. 3, 2015--
Orbital ATK, Inc. (NYSE: OA), a global leader in aerospace and defense
technologies, announced today that it has been awarded a production
order from the U.S. Army to fulfill additional U.S. Air Force
requirements for the DSU-33D/B proximity sensor. This order, valued at
approximately $27 million, is a follow-on award to the full-rate
production contract signed in 2013. The sensor provides a fire pulse to
the bomb fuze, enabling precise detonation to maximize the effect of the
weapon. This contract marks the fourth full-rate production contract
awarded to Orbital ATK and this is the second Delivery Order issued
against that contract.
We have provided DSU-33 sensors to the U.S. Armed Forces since 1999.
Additional production of this version is testament to their quality and
dependability, said Cary Ralston, vice president and general manager of
the Missile Products division of Orbital ATK s Defense Systems Group.
Accuracy and dependability on the battlefield are vital and our
employees give their all to meet the expectations of the warfighter.
The DSU-33D/B is an all-weather, active, radio-frequency, ranging radar
that senses the height of the weapon above the target area. It is used
in conjunction with FMU-139 and FMU-152 bomb fuzes to detonate the
weapon at a fixed height above surface targets, maximizing the warhead's
blast and fragmentation effects. Orbital ATK is the sole provider of the
DSU-33 sensor family, delivering more than 154,000 sensors to the U.S.
Air Force, U.S. Navy, and allied nations since starting production in
1999.
The DSU-33D/B will be produced at the Allegany Ballistics Laboratory
(ABL) facility in Rocket Center, West Virginia. ABL is a U.S.
Navy-owned, Orbital ATK-operated facility specializing in advanced
manufacturing technologies for a variety of programs supporting current
and future U.S. industrial base needs in advanced fuzing and
integration, conventional munitions assemblies, solid rocket motor
propulsion and advanced material structures.
Orbital ATK Defense Systems Group is an industry leader in providing
innovative and affordable ammunition, precision and strike weapons,
electronic warfare systems, and missile components across air-, sea-,
and land-based systems.
