ECLIPSE

Firefly Aerospace and Northrop Grumman are co-developing Eclipse, a new medium launch vehicle that combines the best flight-proven technologies, systems, and mission experience from both companies.

Key Benefits:

Fills a void in the underserved medium-lift market.
Supports commercial, civil, national security, and international launch markets.
Delivers to customers' preferred orbits with competitive pricing.
Lower cost and increased performance.
Provides greater launch schedule availability from Wallops Island.

Eclipse is an evolutionary successor to the Antares launch vehicle, offering a significant leap in power, performance, and payload capacity.

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.
