The US Army’s hypersonic Dark Eagle missile recently passed a critical test

Interestingly, despite a reported range of 1,725 miles, the Army has acknowledged that the all-up-round test, which took place on June 28, saw the missile cover roughly 2,000 miles from its launch site in Hawaii to its impact point at a test range in the Marshall Islands.

The C-HGB also serves as the HGV basis for the Navy’s ship-launched Intermediate-Range Conventional Prompt Strike (IRCPS) weapon, which would operate similarly, but is intended for service aboard the Navy’s stealthy Zumwalt-class destroyers.

Hypersonic Glide Vehicles are one of two classes of modern hypersonic weapons and the only type currently believed to be in service for any nation. China has a similar weapon in service in the DF-ZF, which is carried aloft via the DF-17 intermediate-range ballistic missile that’s meant for anti-ship duties, while Russia’s nuclear Avangard HGV is meant to be delivered via the nation’s newest intercontinental ballistic missile, the RS-28 Sarmat.

The other type of modern hypersonic weapon, hypersonic cruise missiles, fly under power using exotic propulsion systems like scramjets. While several such weapons are in development, and Russia has even made claims about putting one into service, to date, evidence suggests no HCMs have made their way into operational use.

Dark Eagle saw a series of challenges in early testing, including a number of booster failures and issues tied to the Lockheed Martin-sourced launcher — but notably, most of its issues seemed to be tied to supporting systems rather than to the C-HGB itself. This echoes challenges faced by the US Air Force’s testing of another hypersonic glide vehicle, the AGM-183A ARRW, which still has an uncertain future due to its prolonged testing woes.

Dark Eagle and its C-HGB, on the other hand, may now be cruising toward active service, as the Army has previously stated that the weapon system is ready to go into production, pending successful all-up-round flight testing. Army officials have claimed that the first truly production-quality weapon could be delivered within just six weeks of the missile proving itself in testing, with the first battery of eight missiles arriving within 11 months.

Once in service, each of the US Army’s Dark Eagle batteries will consist of four Transporter Erector Launchers on modified M870A4 trailers, with two missiles housed in each launcher for a total of eight per battery. Two more vehicles — a Battery Operations Center (BOC) for command and control and a BOC support vehicle — will handle the rest of the launch-related duties.

The 5th Battalion, 3rd Field Artillery Regiment at Joint Base Lewis-McChord, Washington is slated to stand up the first Dark Eagle battery once it reaches operational service, which the Army projects will be in 2025.
