The Northrop Grumman name and logos are registered trademarks of Northrop Grumman. If that was the case, then the Air Force will have developed a new family of launch vehicles that would be primarily used only for national security payloads, resulting in higher overhead costs to DoD, while missing an opportunity to maximize the competitive posture of US industry. 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. 7 0 obj [14] The USAF moved 7 launches from Delta IV to Atlas V.[15] To end litigation and competition for a limited market, both companies agreed to form the United Launch Alliance (ULA) joint venture.

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. Abstract. To do so, ULA has had to maintain sufficient cost accounting systems within the company. 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. The Medium & Medium-Plus vehicles use a single Common Booster Core (CBC), while the Heavy variant uses three CBCs. DOD expects to spend about $9.5 billion over the next 5 years acquiring launch hardware and services through the program, during which time it will also be working to certify new launch providers. 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.

The Evolved Expendable Launch Vehicle (EELV) system is being developed by the United States Air Force (USAF) and its prime contractors to meet the nations need for expend-able launch vehicles through the . . for GPS III Launch Services . 2762 0 obj <> endobj The Atlas family of launch vehicles has and continues to be a national workhorse, logging nearly 649 total launches (NSS, civil, and commercial) to date. As of September 2019, it has two manifested classified national security flights for the USAF in 2021.[43][44][45]. 0000005993 00000 n stream [38] This launcher features a reusable first stage and fairings, which lowers the cost per mission. APL requirements are not addressed in the SIS but their As of 2019, these launch vehicles were the primary methods for launching U.S. military satellites, along with the Falcon 9 developed by SpaceX. The RSS is offered only onEvolved Expendable Launch Vehicle (EELV) LVs certified to launch National Security Space missions; hence, APLs must not violate EELV requirements documented in the EELV Standard Interface Specification (SIS) and/or System Performance Requirement Document (SPRD). hbbd```b`` d#XD 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. 0000000016 00000 n [46] OmegA was a rocket design with two main solid stages, a cryogenic upper stage, and the possibility of additional solid-rocket strap-on boosters. The ESPAStar platform leverages the available mass margin from any EELV launch to provide an affordable path to space for payloads. [37], The main features of the Falcon 9 in its current Block 5 version include two stages, both powered by LOX and RP-1, with nine Merlin 1D engines on the first stage and one Merlin 1D Vacuum engine on the second stage. [46] As of 2019, Blue Origin expected a first launch of New Glenn in 2021.

[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. [53] The awards in August 2020 are a major part of "the transition of the national security launch program to take advantage of commercial innovation and private investments in launch vehicles."[47]. @(l(MW a 67E1efWmh8s`e3XY|t+$8f`~!Af6 Dy3 stream The Delta IV family is capable of carrying 10,818 kg (23,851 lbs) to geosynchronous transfer orbit, and can lift 21,772 kg (48,000 lbs) to low-Earth orbit.
