[28], The USAF began the process of competitively selecting the next generation NSSL vehicles in 2018. The payload interface at each port has been standardized, allowing for hosted and separable payload interchangeability, late payload integration and manifest changes. The EELV program was initiated in 1994 and planned to be a "rolling-downselect" of launch vehicle providers from four to one. hb```B ;6hvfa.

As of that time, Vulcan Centaur was on track for a 2021 launch. Reducing the cost of launches and ensuring national access to space were the two main goals of the USAF space launch/EELV program. [46] OmegA was a rocket design with two main solid stages, a cryogenic upper stage, and the possibility of additional solid-rocket strap-on boosters.

The EELV competition was expected to produce the next generation of launch vehicles to replace all medium to heavy launchers, Lockheed Martin's Atlas, Titan II and Titan IV series, and McDonnell Douglas's Delta series, with a single family of vehicles capable of launching medium and heavy payloads into orbit at a significantly lower cost. [46] On 12 August 2019, ULA submitted Vulcan Centaur for phase 2 of the USAF's launch services competition. The FY 2016 NDAA recognized that a small number of Russian engines could be needed to ensure a near-term competitive environment. 0000135929 00000 n 0000010365 00000 n 0000000776 00000 n Abstract.

The Delta IV Medium, Medium-Plus and Heavy configurations are evolved from flight proven Delta II and Delta III systems while incorporating the latest technology into a family of vehicles maximizing the use of common hardware. hbbd```b`` d#XD SpaceX and ULA were the two vendors selected via the competition to supply launches to the US military in the 20222027 timeframe. One of the Air Forces long-term goals for the EELV program is to have at least two certified launch providers able to compete for the full range of national security launches. [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.

As with the Delta IV, either a 4m or 5m fairing is used to shroud the payload, and vehicles are defined by the number of solids and the size of the payload fairing. The Atlas V provides medium and intermediate lift capability and is evolved from flight-proven Atlas and Titan programs, maximizing flexibility and reliability. The platform is optimized for GEO missions, but is adaptable for LEO and MEO missions. hb``g``f`f`.
