[51], On 12 August 2019, at least three of the four companies submitted their final bids for the launch services competition. The approach taken in the development of. These launch vehicles provide critical spacelift capability to support Department of Defense and other National Security missions (together known as National Security Space (NSS) missions). At the same time, another 14 boosters were to be procured competitively beginning in 2015, with the initial launches to be performed in 2017. RFP F04701-97-R-0008 19 June 1998 ii . In 1998, when it appeared the growth in the commercial satellite industry would be able to sustain two providers of launch services, the Air Force decided to award contracts to both Boeing and Lockheed Martin for their respective launch capabilities. [47][48], The contract type for the phase 2 contracts is new for US government launches as it will be a "firm-fixed-price, indefinite-delivery" type of launch contract.

After many years of government-funded studies on the subject of modernized launch vehicle systems, the Air Force finally developed a "roadmap" in 1994 for the acquisition of Evolved Expendable Launch Vehicles (EELVs) to replace the DELTA IIs, ATLAS IIs, and TITAN IVs then in use at Cape Canaveral.

The Atlas V provides medium and intermediate lift capability and is evolved from flight-proven Atlas and Titan programs, maximizing flexibility and reliability. Launch performance can be augmented by adding either two or four solid rocket motors. EELVs were to reduce costs by being based on standardized fairings, liquid core vehicles, upper stages, and solid rocket boosters. 2 0 obj [13] Boeing and Lockheed Martin were each awarded US$500 million for the final phase of the bid.

Thats Defining Possible. In October 2018, the USAF awarded development funding to ULA, NGIS, and Blue Origin to further the design of their rockets before a subsequent competition for award to build the launch vehicles. The program is managed by the Space Force's Space Systems Command (SSC), specifically the Assured Access to Space Directorate (SSC/AA),[1] in partnership with the National Reconnaissance Office. Reducing the cost of launches and ensuring national access to space were the two main goals of the USAF space launch/EELV program. endobj The payload interface at each port has been standardized, allowing for hosted and separable payload inter-changeability, late payload integration, As of 2017, SpaceX is completing this certification process with its Falcon 9 vehicle to also begin providing launch services for NSS missions. @media only screen and (min-device-width : 320px) and (max-device-width : 480px) { 4.0,` 3p H.Hi@A> Evolved Expendable Launch Vehicle Secondary Payload Adapter System Interface Specifications For . 13 0 obj 0000003910 00000 n 0000005993 00000 n 27 33 [19], In December 2012, the DoD announced a re-opening of the EELV-class launch vehicle market to competition while authorizing the USAF to proceed with a block buy of "up to" 36 boosters from ULA. ]p2c*lR-fHqmh"?
