On May 7, 2009, KEI program was canceled due primarily to financial reasons. First stage rocket motor testsThere were five first-stage rocket motor tests planned to be carried out by Alliant Techsystems (ATK) in Promontory, Utah.[2] The second test firing of a KEI first stage rocket motor was conducted on June 14, 2007. The static firing included a full duration burn and a demonstration of the thrust vector control nozzle.[3][4] The fourth test firing of the first-stage rocket motor was completed on November 13, 2008. The test demonstrated a successful operation of the first-stage rocket motor in its final flight configuration that was to be used during a Summer 2009 flight test. Due to the cancellation of KEI in May 2009, this test did not occur.[5] Some KEI program implementation and funding historyOn May 7, 2009, Missile Defense Agency executive director David Altwegg announced that KEI would be canceled due to technical and financial reasons. The announcement to kill KEI had previously been overlooked during Defense Secretary Robert Gates' April 6 press conference on changing priorities in the FY10 defense budget.[6] In an email of October 21, 2009 Senator Dianne Feinstein announced to her constituency that about $40 Million had been added to "the Senate… version of the fiscal year 2010 Defense Appropriations bill".{{clarify|date=February 2011}} See also
