Alliant Techsystems has selected L-3 Communications, to provide key components of the avionics subsystem for the First Stage of NASA's next-generation human launch vehicle -- the Ares I. In December 2005, NASA named ATK as the prime contractor for the Ares I first stage. In August 2007, ATK received a $1.8 billion contract from NASA to continue the design, development, test and evaluation (DDT and E) phase of the first stage through 2014.

The First Stage consists of a five-segment solid rocket booster, similar to the four-segment boosters used for Space Shuttle launches.

"L-3 won a hard-fought competitive procurement, said Mike Kahn, Vice President of Space Launch Systems, ATK Launch Systems Group. They showed their innovation and ability to perform this critical role and we're pleased to have them on the Ares I First Stage team."

L-3's Cincinnati Electronics subsidiary is responsible for providing the Booster Control/Power Distribution Unit, Data Acquisition/Recorder Unit, Hydraulic Power Unit Controller, Ignition/Separation Unit and Recovery Control Unit. ATK will be responsible for avionics subsystem integration and certification.

Each avionics subsystem flight set consists of 18 electronic boxes located throughout the Ares I first stage. Under the contract, L-3 Cincinnati Electronics will conduct various aspects of the DDT and E phase including delivery of development, qualification, system integration and flight test sets to begin in 2009. The L-3 DDT and E contract extends through 2014.
