ATK (Alliant Techsystems)
has successfully tested a high-performance Advanced Solid Axial
Stage (ASAS(TM)) 32-inch-diameter solid rocket motor demonstrating critical
technologies required for future missile defense, as well as strategic and
tactical mission applications.

The ASAS 32-58V motor is the latest member of the ASAS family of booster
motors. The project was dubbed RAVEN (RApid VEctoring Nozzle), representing a
primary technology objective of the test. The motor met all test objectives,
including high-angle thrust vector control (TVC) and a high nozzle slew rate.

MPC Products Corporation, Skokie, Ill., provided the nozzle actuators and
controller for the test. The motor utilized an ATK-designed “smart”
electronic safe and arm (ESA) device and a pyrotechnic igniter for rapid motor
ignition. ATK Composites TCR Division provided the high-strength TCR(TM)
fiber/resin system used by ATK Elkton to fabricate the motor case.

Don Shaffer, president, ATK Elkton, noted the strong interest of the
customer community in the test and stated that “the performance of the motor
was exceptionally close to what was predicted. This test demonstrated that
our analytical models and our design and manufacturing processes are well
understood for high-performance motors. This effort establishes a solid
platform from which we can design and build rocket motors for the next
generation of missiles.”

ATK is a $2.2 billion aerospace and defense company with strong positions
in propulsion, composite structures, munitions, precision capabilities, and
civil and sporting ammunition. The company, which is headquartered in Edina,
Minn., employs approximately 12,100 people and has three business groups:
Precision Systems, Aerospace, and Ammunition and Related Products. ATK news
