The Dark Eagle is not a single weapon so much as an integrated system of components developed across multiple contractors and shared, in part, with the U.S. Navy. Understanding how those pieces fit together clarifies both what the weapon can do and where its development risks have been concentrated.

The missile booster is a two-stage rocket developed by Lockheed Martin and Northrop Grumman. When mated with the hypersonic glide body, the complete assembly is designated the Navy-Army All Up Round plus Canister, or AUR+C. This combined form is what actually leaves the transporter erector launcher during a live-fire event. Critically, the same booster stack serves both the Army’s ground-launched LRHW and the Navy’s Conventional Prompt Strike system, which can be fired from surface vessels and submarines. That cross-service commonality is a deliberate acquisition choice — it spreads development cost and creates production efficiencies that neither service could achieve independently.
