Castelion(@Castelion):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.
