WASHINGTON — Blue Origin filed a protest with the U.S. Government Accountability Office on Monday challenging the Air Force’s plan to select two providers in the next procurement of launch services under the National Security Space Launch program.

Blue Origin, a rocket manufacturer and suborbital spaceflight company founded by Jeff Bezos, filed what is known as a “pre-award” protest with the GAO, arguing that the rules set by the Air Force do not allow for a fair and open competition.

“The Air Force is pursuing a flawed acquisition strategy for the National Security Space Launch program,” states a Blue Origin fact sheet that outlines the reasons for the protest.
