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 EELV system included launch vehicles, infrastructure, support systems, and interfaces. 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. endobj On September 29, 2015, the Air Force awarded an EELV Launch Capability (ELC) contract to ULA valued at $882 millionthe latest such contract the Air Force has awarded to ULA since ULA became the only source for launches under the EELV program. 4.0,` 3p H.Hi@A> [48][47] stream 2023 Northrop Grumman. 0000058657 00000 n That includes five engines that ULA currently has in its possession, which are not limited by the sanctions, since they were fully paid for prior to the Russian invasion of Crimea. The Medium & Medium-Plus vehicles use a single Common Booster Core (CBC), while the Heavy variant uses three CBCs. Up to five Aerojet Rocketdyne Graphite-Epoxy Motor solid rocket boosters can be added to increase vehicle performance, and two diameters of payload fairing are available. These launch system investments include efforts required to complete the transition off non-allied engines and build upon the Air Force's Booster Propulsion Technology Maturation efforts started in early 2015 and the Rocket Propulsion System investments awarded in early 2016. The EELV program was initiated in 1994 and planned to be a "rolling-downselect" of launch vehicle providers from four to one. As of 2015 the EELV program was actively pursuing a competitive scenario for launch acquisitions, but the launch industry is currently undergoing numerous changes, and the makeup of the industry in the future is uncertain.

As the Air Force's spacelift modernization program, EELV was designed to increase reliability and reduce launch costs by at least 25 percent over heritage Atlas, Delta and Titan space launch systems. 0000005030 00000 n @media only screen and (min-device-width : 320px) and (max-device-width : 480px) { %%EOF That strategy was designed to (1) . 2 0 obj Expendable launch system program of the United States Space Force, List of Falcon 9 and Falcon Heavy launches (20102019) 2018, "Space Systems Command Celebrates First Anniversary as USSF Field Command", "JUST IN: National Reconnaissance Office Embracing Commercial Tech", "Defense Primer: National Security Space Launch", "EELV isn't what it used to be: Air Force changes launch program name", "Air Force establishes National Security Space Launch program", "National Security Presidential Directive 40: U.S. Space Transportation Policy", "Two Former Boeing Managers Charged in Plot to Steal Trade Secrets from Lockheed Martin", "Pentagon strips 7 launches from Boeing Delta 4 rocket", "Reusable Successor To EELV Moving Ahead", "Prototype Reusable Rocket Effort Felled by U.S. Budget Woes", "EELV Update: A Split Decision and a New Beginning", "SpaceX Awarded Two EELV-Class Missions from the United States Air Force", "After successful landing, SpaceX to sue Air Force to compete for launch contracts", "SpaceX wins intermediate victory over US in launch contract case", "SpaceX says rocket purchases violate Russian sanctions, gets injunction", "SpaceX elbows into Air Force launch program after dropping lawsuit", "SpaceX, Air Force Settle Lawsuit over ULA Blockbuy", "SpaceX Falcon 9 Certified for Military Launches", "SpaceX wins $82 million contract for 2018 Falcon 9 launch of GPS 3 satellite", Nine reference orbits & payloads for USDoD space missions, "DOD Releases Fiscal Year 2021 Budget Proposal", "ULA Delta IV launches the NROL-25 military satellite from VAFB", "United Launch Alliance Successfully Launches GPS III Satellite for U.S. Air Force Space and Missile Systems Center", "Delta IV Medium's well-earned retirement with GPS finale", "ULA stops selling its centerpiece Atlas V, setting path for the rocket's retirement", "ULA targeting September 26 for next Delta 4-Heavy launch attempt", "SpaceX flies historic 10th mission of a Falcon 9 as Starlink constellation expands", "Air Force requirements will keep SpaceX from landing Falcon 9 booster after GPS launch", "Air Force certified Falcon Heavy for national security launch, but more work needed to meet required orbits", "Air Force certified Falcon Heavy for national security launch but more work needed to meet required orbits", SpaceX wins $130 million military launch contract for Falcon Heavy, U.S. department of defense - Contracts for February 19, 2019, SMC Issues Final RFP For Five EELV Launches; SBIRS & 4 Classified Payloads, "Air Force Awards Launch Vehicle Development Contracts to Blue Origin Northrop Grummand ULA", "Pentagon picks SpaceX and ULA to remain its primary launch providers", "In a consequential decision, Air Force picks its rockets for mid-2020s launches", "Northrop Grumman to terminate OmegA rocket program", "Vulcan Centaur Rocket on Schedule for First Flight in 2021: ULA Submits Proposal for U.S. Air Force's Launch Services Competition", "Blue Origin files protest challenging 'flawed' Air Force strategy for choosing launches", https://en.wikipedia.org/w/index.php?title=National_Security_Space_Launch&oldid=1140354433, Space launch vehicles of the United States, Pages with non-numeric formatnum arguments, Short description is different from Wikidata, Articles containing potentially dated statements from November 2022, All articles containing potentially dated statements, Wikipedia articles in need of updating from June 2020, All Wikipedia articles in need of updating, All Wikipedia articles written in American English, Creative Commons Attribution-ShareAlike License 3.0. place critical United States Government assets and capabilities into space; augment space-based capabilities in a timely manner in the event of increased operational needs or minimize disruptions due to on-orbit satellite failures, launch failures, or deliberate actions against U.S. space assets; support government and commercial human space flight.
