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. Attachment 6 Evaluation Criteria. The Delta IV Heavy launch vehicle uses three Common Booster Cores (CBCs) each powered by a Pratt and Whitney Rocketdyne RS-68A engine, a Delta Cryogenic Second Stage 5m (DCSS) powered by an RL10, and a 5m payload fairing. This would be difficult to achieve since projections showed that the EELV would not be able to meet the requirements of as much as 42 percent of the estimated commercial market. 0 N } "zQjC+6\Ei8rF2+m0 Download PDF. 0000001979 00000 n Under Solicitation Number FA8811-16-R-000X, released 14 March 2017, Air Force Space Command - Space and Missile Systems Center draft solicitation ws to implement the Evolved Expendable Launch Vehicle (EELV) strategy to transition from the use of "non-allied" [aka Russian RD-180] engines and to implement affordable assured access to space via sustainable competition with commercial providers. endobj [ /ICCBased 12 0 R ] Accommodates combinations of hosted (6 max) or separable (12 max) payloads at all mounting ports, 1.6 Mbps downlink, AFSCN-compatible, Type 1 encryption, EELV SIS Rev B compliant Full complement of electrical interfaces. %PDF-1.4 % [10] The initial bids came from four major defense contractors: Lockheed Martin, Boeing, McDonnell Douglas, and Alliant Techsystems. 1.

At the same time, another 14 boosters were to be procured competitively beginning in 2015, with the initial launches to be performed in 2017. The contractor was standardizing payload interfaces, launch pads, and infrastructure so that all configurations of each contractor's EELV family can be launched from the same pad and payloads can be interchanged between vehicles in the same class (i.e., medium, intermediate, or heavy). [38] This launcher features a reusable first stage and fairings, which lowers the cost per mission. The USAF began the EELV program in 1994, following many years of government-funded studies into improved systems and architecture. 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. 2 0 obj [48][47] hs2z\nLA"Sdr%,lt [28], The USAF began the process of competitively selecting the next generation NSSL vehicles in 2018. DOD's Evolved Expendable Launch Vehicle (EELV) program is the primary provider of launch vehicles for U.S. military and intelligence satellites. The Medium & Medium-Plus vehicles use a single Common Booster Core (CBC), while the Heavy variant uses three CBCs. The strategy invests in new and/or upgraded commercial launch solutions that also meet National Security Space (NSS) requirements.
