ATK's SRBs: No Longer Need?

NASA: ATK has to shrink to remain competitive, Salt Lake Tribune
“Unfortunately the solid rocket industry has been overcapitalized for many, many years,” Bolden told an appropriations subcommittee as part of his push for President Barack Obama’s new direction for NASA. “We are carrying 70 percent of an industry for a capability that no one uses but NASA.” And NASA isn’t sure to what extent it wants to use it any more either. ATK’s solid rocket motors have launched the shuttle into orbit for decades and the company has been constructing the Ares rocket as its replacement. But President Barack Obama wants to drop Ares and the overall Constellation program. In its place, Obama would pay for flights on as-yet-unbuilt private space vehicles to reach low-earth orbit, while NASA would focus on creating a completely new deep-space vehicle starting in 2015.”
