Sierra Space

Positioning

Sierra Space is a US space company whose operating engine is now defense manufacturing: an SDA Tranche 2 award ($740M/18 missile-warning satellites, first structures completed early), a new $798M AMDT3 award (July 2026, 18 more Tranche 3 tracking satellites for Golden Dome), and a classified $450M intelligence contract. A new CEO (ex-Maxar Dan Jablonsky, February 2026) is converting it into a high-rate manufacturer, while its Dream Chaser was downgraded (NASA CRS-2 modified, first flight now a free-flyer demo with ISS docking cancelled). It raised a $550M Series C in March 2026 (>$1.4B cumulative, a $5.3B 2023 valuation).
