Although additional new entrants may be able to compete in the future, it is unlikely that others will be ready to compete before Phase 2. Since 2019 there are four vehicles certified by the Department of Defense to conduct NSSL launches: Atlas V, Delta IV Heavy, Falcon 9 and Falcon Heavy. Making space accessible. The EELV was expected handle the bulk of the U.S. government's launch requirements after the year 2000 and was also expected to be used for commercial applications. The Falcon Heavy is a heavy-lift rocket developed and produced by SpaceX. [41] He clarified: "I certified them to compete last year" and "[o]ne of the requirements behind certification is to fly three missions." [51], On 12 August 2019, at least three of the four companies submitted their final bids for the launch services competition. 97 24 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.
