[5] Delta IV Medium was retired in August 2019. 0000000956 00000 n 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. EELV was important not only to reducing the launch costs of the Department of Defense, but also to the continued world-wide competitiveness of the US commercial launch industry.

Development includes all efforts leading up to and including EELV certification (and the validation of all NRE work) to meet the full range of EELV mass-to-orbit requirements 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. 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. 0000004093 00000 n Evolved Expendable Launch Vehicle (EELV) standard interface specification, as well as Falcon 9 and Falcon Heavy. 0000010525 00000 n 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. 2612 [33][34], Each Atlas V launch vehicle is based on a Common Core Booster powered by one NPO Energomash RD-180 engine with two combustion chambers and a Centaur upper stage powered by one or two Pratt & Whitney Rocketdyne RL10A-4-2 engines. trailer <<8D9465B782A042F99BA9A4986B1592D1>]/Prev 881083>> startxref 0 %%EOF 59 0 obj <>stream hb``g``f`f`.

The USAF and United States Space Force (USSF) plan to use the next generation NSSL launch vehicles until at least 2030.[31]. Blue Origin was awarded $500 million of phase 1 funding for further development of New Glenn as a potential competitor in future contracts. [41] He clarified: "I certified them to compete last year" and "[o]ne of the requirements behind certification is to fly three missions." -2- 0000027829 00000 n Launch performance can be augmented by adding either two or four solid rocket motors.
