United Launch Alliance

United Launch Alliance (ULA) je američki pružatelj usluga lansiranja svemirskih letjelica koji proizvodi i upravlja brojnim raketnim vozilima koja su sposobna lansirati svemirske letjelice u orbite oko Zemlje i na druga tijela u Sunčevom sistemu. Kompanija, koja je zajedničko ulaganje Lockheed Martin Space -a i Boeing Defense -a, i Space & Security, osnovana je u decembru 2006. Korisnici lansiranja United Launch Alliance -a su Ministarstvo odbrane (DoD), NASA i druge organizacije.^[1]

Kompanija je formirana u decembru 2006. godine kao zajedničko ulaganje između Lockheed Martin Space i Boeing Defence, Space & Security.^[2] Primarni kupci ULA-e su Ministarstvo odbrane (DoD) i NASA.^[3] ULA pruža usluge lansiranja pomoću lansirnih vozila Atlas V i Vulcan Centaur. Koristeći ove i penzionisane lansirne sisteme Delta II i Delta IV, ULA je lansirala korisna opterećenja uključujući vremenske, telekomunikacione i satelite nacionalne bezbjednosti, naučne sonde i orbitere. ULA također lansira Boeing Starliner i komercijalne satelite.^[4] Atlas V će se povući nakon što završi preostala lansiranja. U 2024.^[update], preostalo je sedamnaest lansiranja Atlasa V.

Trenutna ULA flota

Delta IV Heavy

Atlas V 551

Godine 2014. ULA je započela razvoj rakete Vulcan Centaur kao nasljednika Atlas V i Delta IV, s početnim letom planiranim za 2019.^[5] ^[6] Nakon višestrukih kašnjenja, prvi let se dogodio 8. januara 2024.^[7] sa početnom misijom lansiranja lunarnog uređaja Astrobotic Technology Peregrine.^[8]^[9]
