Rockets and Launch Services

ULA is the one of the most experienced, reliable and accurate launch service provider delivering unmatched value, a tireless drive to improve, and commitment to the extraordinary.

Vulcan - Vulcan is an evolution of the proven Atlas V and Delta IV vehicles. ULA created the heavy-lift launch vehicle Vulcan in order to comply with NSSL regulations. The spacecraft is encapsulated in a 5.4-m- (17.7-ft-) diameter payload fairing (PLF), a sandwich composite structure made with a vented aluminum-honeycomb core and graphite-epoxy face sheets. The bisector (two-piece shell) PLF encapsulates the spacecraft. The payload attach fitting (PAF) is a similar sandwich composite structure creating the mating interface from spacecraft to upper stage. The PLF separates using a debris-free horizontal and vertical separation system with spring packs and frangible joint assembly. Vulcan is available in four standard offering configurations including zero, two, four and six solid rocket booster (SRB) variants. Vulcan serves in a diverse range of markets including commercial, civil, science, cargo and national security space customers.

Atlas V - The Atlas V family represents ULA's commitment to enhanced competitive launch services for the U.S. government. Since their debut in August 2002, Atlas V vehicles have achieved 100 percent mission success over more than 70 launches. Built modularly with flight-proven elements, Atlas V has followed a carefully executed program of incremental improvements resulting in 100 percent mission success. United Launch Alliance's (ULA) ATLAS program embodies reliability, flexibility, and performance, achieving 100% launch success across more than 600 Atlas program launches. It supports critical missions, including planetary exploration, classified defense systems, and essential commercial operations. Furthermore, ATLAS plays a vital role in human spaceflight, such as launching astronauts to the International Space Station aboard Boeing's Starliner capsule, delivering missions safely and on time. It has 2 models : ATLAS V 400 series and ATLAS V 500 series.

Delta IV - The Delta IV Heavy rocket was the pinnacle in the Delta family evolution. The Delta IV Heavy rocket was a workhorse for the National Reconnaissance Office (NRO) launching 12 missions delivering critical national security payloads. The heavy-performance rocket is recognized for delivering high-priority missions for national security and NASA's first Orion spacecraft on an uncrewed flight test and sent the Parker Solar Probe to study the atmosphere of the Sun. The Delta IV launch system was available in three configurations: the Delta IV Medium+, with two or four solid rocket motors (SRMs) and the Delta IV Heavy.

Delta-II - The Delta II program has a rich history. Over 29 years, the rocket launched 155 times with 100 consecutive successful missions, culminating in the final ICESat-2 flight for NASA. The Delta II launch vehicle offered the user a choice of three fairings: a 2.9-m (9.5-ft)-diameter skin-and-stringer center section fairing (bisector), and two versions of a 3-m (10-ft)-diameter (bisector) composite fairing with two different lengths. Delta II launched many memorable missions including NASA’s rovers Spirit and Opportunity, the Phoenix Mars Lander, all operational GPS missions through the constellation of 21 GPS II-R missions for the Air Force, and commercial missions for Iridium, Globalstar and three DigitalGlobe satellites.
