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. [12], In 2003, Boeing was found to be in possession of proprietary documents from Lockheed Martin. % The Falcon Heavy is a heavy-lift rocket developed and produced by SpaceX. 0000002177 00000 n 2 0 obj >> In August 2021, ULA announced that Atlas V would be retired, and all 29 remaining launches had been sold.

In paying ULA for such fixed launch costs and executing the EELV program under a cost-plus contract, the DoD has reimbursed ULA for allowable, reasonable, and allocable costs for its launches, while requiring ULA to reimburse it on a per-launch basis for launches that ULA sells to its non-DoD customers.

Either a 4m or 5m fairing encapsulates the payload. Delta IV Medium flew with two or four SRBs on a single Common Booster Core. The purpose of this paper is to describe the development of the EELV Standard Interface Specification (SIS) and its implications for spacecraft designers. The FY 2016 NDAA recognized that a small number of Russian engines could be needed to ensure a near-term competitive environment. The Atlas V's inaugural flight was marked by the successful launch of a Hotbird-6 commercial satellite in August 2002. Delta IV CBCs and DCSSs are integrated horizontally before being transported to the launchpad. The launch occurred on December 23, 2018.[40]. 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 ESPAStar platform's 6 payload ports are capable of accommodating any combination of up to 6 hosted and 12 separable (fly-away) payloads (maximum 1 hosted or 2 separables per port).
