Sierra Nevada Corporation (SNC)

Sierra Nevada Corporation (SNC) is an American aerospace and national security company founded in 1963 by John Chisholm and headquartered in Sparks, Nevada. SNC is best known for the Dream Chaser spaceplane — a reusable, runway-landing cargo spacecraft for ISS resupply under NASA's CRS-2 program, designed to launch atop a Vulcan Centaur rocket. In 2021, the Dream Chaser program was transferred to Sierra Space, an independent SNC subsidiary. SNC's broader portfolio spans mission systems, avionics, power systems, communications, intelligence, surveillance, and reconnaissance (ISR) solutions for defense and space customers. The company has contributed to hundreds of government and commercial space programs.
