Abstract. [24] The USAF and SpaceX settled the lawsuit in Jan 2015 by opening up more launches to competitive bidding. 0000076318 00000 n Program cost savings are achieved through operability improvements such as the use of common components and infrastructure, a standard payload interface, standardized launch pads and reduced on-pad processing; and acquisition improvements such as launch vehicle block buys. [5][6], The NSSL program launches the nation's most valuable military satellites; contracts to launch lower value payloads, such as those of the Space Test Program, are awarded using different methodologies.[7]. [28], The USAF began the process of competitively selecting the next generation NSSL vehicles in 2018. SpaceX bid the existing launch vehicles of Falcon 9 and Falcon Heavy, while Blue Origin was expected to bid New Glenn, ULA bid Vulcan Centaur, and NGIS's bid status was not reported. @(l(MW a 67E1efWmh8s`e3XY|t+$8f`~!Af6 Dy3 This requirement has been satisfied by the Falcon Heavy test flight in February 2018, Arabsat-6A in April 2019, and the STP-2 launch in June 2019.

Up to five solid rocket boosters can be added to augment performance. To do so, ULA has had to maintain sufficient cost accounting systems within the company. [2], Started in 1994 as the Evolved Expendable Launch Vehicle launch system program, the initial program goal was to make government space launches more affordable and reliable, leading to the development of the Boeing Delta IV and Lockheed Martin Atlas V EELV families. 2612 The Northrop Grumman name and logos are registered trademarks of Northrop Grumman. 6 0 obj DOD expects to spend about $9.5 billion over the next 5 years acquiring launch hardware and services through the program, during which time it will also be working to certify new launch providers.

The goal was the creation of a cost-efficient and reliable family (or families) of "right size" spacelifters based on standardized fairings, liquid core vehicles, upper stages, and solid rockets. 0000015937 00000 n For almost 10 years, the EELV program had only one company capable of providing launches.
