Sierra Space Closes $550M Series C at $8B Valuation — Defense Pivot Complete

Sierra Space raised $550M in Series C equity on March 5, 2026, led by LuminArx Capital Management with participation from General Atlantic, Coatue, Moore Strategic Ventures, and Andalusian Private Capital, valuing the company at $8 billion post-money. The round arrives as Sierra Space executes a $740M SDA Tranche 2 contract (18 missile-warning satellites, three months ahead of schedule) and a classified $450M national security award. CEO Dan Jablonsky, who replaced founder Fatih Ozmen in February 2026, is tasked with transitioning the company from development-heavy to high-rate manufacturing. Dream Chaser demo flight is now targeted for late 2026 as a free-flight uncrewed demonstration rather than ISS resupply.
