Bryon Hargis(@hargsb):Deterrence depends on unapologetic American strength: weapon systems adversaries fear, produced in quantities they can't imagine, at a price taxpayers can afford. Grateful to our Series C investors who are trusting us with the significant capital required to manufacture deterrence at scale and our customers for trusting us with their mission. Thank you for believing in us, we won’t let you down.

Castelion is proud to announce our $1 billion Series C. We’re growing fast and our mission hasn't changed: build the weapons required to deter the next major war, affordably, rapidly, and at massive scale. This funding accelerates Blackbeard production, develops a longer-range strike system, and starts work on defensive systems. Thank you to @JPMorgan Chase's Strategic Investment Group, @a16z, @OneCarlyle, @lightspeedvp, @LavrockVC, @AltimeterCap, @TRowePrice, @generalcatalyst, and #Interlagos# for backing that work.
