ATK awarded $429 million contract modification

Alliant Techsystems has received a contract modification from NASA valued at $429 million for the production and refurbishment of reusable solid rocket motors for the Space Shuttle program.

Alliant Techsystems (ATK) has received a contract modification from NASA valued at $429 million for the production and refurbishment of Reusable Solid Rocket Motors (RSRM) for the Space Shuttle program.

According to ATK, the modification increases the total value of a basic six-and-a half-year contract awarded in October 1998 to approximately $2.83 billion and extends work on the contract through to May 2007.

Under the contract modification, ATK Thiokol Propulsion, Promontory, Utah, will produce and refurbish 35 Reusable Solid Rocket Motor flight sets (70 motors) and three flight support motors that will be used for testing.

The contract issued in 1998 is the sixth in a series of contracts awarded to ATK Thiokol Propulsion from NASA for the design, development, production, and refurbishment of solid rocket motors for the Space Shuttle program.

The Space Shuttle RSRM is the largest rocket motor ever flown and the first designed for reuse. The two RSRM’s on the Shuttle provide 71 percent of thrust at lift-off and during first-stage ascent. From ignition to end of burn, each motor generates an average thrust of 2.6 million pounds and burns for approximately 124 seconds.
