Built on the Success of the Antares and Alpha

Eclipse is an evolutionary successor to the Northrop Grumman Antares launch vehicle, offering a significant leap in power, performance, and payload capacity. The vehicle retains many flight-proven systems from the Antares program with additional upgrades, including a more powerful vacuum-based liquid second stage and an industry-standard 5.4 meter-class fairing that’s customizable to support multiple customer requirements. Eclipse also uses technologies from Firefly’s flight-proven Alpha vehicle, including patented tap-off cycle propulsion technology and carbon composite sandwich structures to reduce mass and costs, and improve strength and reliability.
