New M829E4 Round Provides Abrams Tanks the Ability to Defeat All
Current and Future Threat Armor
DULLES, Va.Jul. 20, 2015--
Orbital ATK, Inc. (NYSE: OA), a global leader in aerospace and defense
technologies, announced today that the M829E4 Advanced Kinetic Energy
120mm tactical tank cartridge has passed First Article Acceptance
Testing and is entering into production. A full material release
decision is expected prior to government fiscal year 2016.
Orbital ATK s current M829E4 production contract includes this first
year s production and exercisable options for two follow-on production
years with a total value of $80 million. An additional five-year,
production contract is expected to fulfill Army inventory requirements.
Ammunition contracts are awarded through the U.S. Army Maneuver
Ammunition Systems through its role as the Single Manager for
Conventional Ammunition, the organization responsible for the
procurement of ammunition for all U.S. Armed Services.
During our more than 30 years of large caliber ammunition program
experience with the Army, we have now partnered with the U.S. Army to
type classify 11 of the 13, 120mm tactical and training rounds for the
Abrams tank, said Dan Olson, vice president and general manager for
Orbital ATK s Armament Systems division of the Defense Systems Group.
From initially providing the 120mm ammunition that upgunned the
Abrams from a 105mm to a 120mm main gun platform until today, our
company has made it a business priority to partner with the Army to
maintain the Abrams' standing as the world's dominant tank.
The M829E4 Armor Piercing Fin Stabilized, Discarding Sabot with Tracer
Cartridge is the Army's fifth generation, 120mm kinetic energy cartridge
that features a penetrator capable of defeating all current, modern
armor protection suites as well as future armor protection concepts.
The cartridge incorporates an advanced design, long-rod penetrator and
an exclusive composite sabot that facilitates the most efficient
transfer of energy to maximize the rod s penetrating power. The use of a
unique propellant blend maintains a consistent muzzle velocity across
operational temperatures ranging from extreme cold to extreme hot.
Additionally, the advanced combustible cartridge case incorporates a
relocated skive joint placement that improves armor crew safety during
handling.
Orbital ATK Defense Systems Group is an industry leader in providing
