The Army Just Got Its Hands On Its First “Dark Eagle” Hypersonic Missile Launchers
The hypersonic missile era is about to officially begin for the U.S. Army.
The U.S. Army is moving closer toward fielding its first Dark Eagle hypersonic missiles, also known as the Long Range Hypersonic Weapon, with the recent delivery of prototype trailer-mounted launchers, as well as other key components of the complete weapon system. In doing so, the Army has also confirmed that Joint Base Lewis-McChord in Washington State is the home of the first unit intended to be equipped with these weapons, something the service has been very tight-lipped about in the past.
Joint Base Lewis-McChord's public affairs office posted a series of pictures online yesterday showing the arrival of the launchers, but the accompanying metadata says that they were all taken on either Sept. 14 and 15 of this year. A common caption attached to each one of the images says that there will be an official ceremony to mark the formal delivery of these trailer-mounted systems to the 5th Battalion, 3rd Field Artillery Regiment, tomorrow.
Though no actual missiles have been delivered to the unit, so far, the launchers and other equipment will allow soldiers to familiarize themselves with various aspects of the LRHW and the general operation of the weapon system. It will also help support the development of the tactics, techniques, and procedures (TTPs) needed to employ the missile in real-world scenarios.
The caption to the images that Joint Base Lewis-McChord released also notes that the prototype LRHW elements now at the base were built under the direction of its Rapid Capabilities and Critical Technologies Office (RCCTO) and that it includes undisclosed “components” that will allow soldiers to “fully train with the system.”
The pictures that were released yesterday show only the launchers, which had not previously been seen, being delivered. These are mounted on modified M870 trailers and will be towed by Oshkosh M983A4 tractor trucks, which are variants of the Heavy Expanded Mobility Tactical Truck (HEMTT). Earlier this year The War Zone
reported on the delivery of two empty box-like canisters, identical to the ones that will hold real Dark Eagle missiles in the future, to what was then an undisclosed location. The Army has previously offered other details about the various expected components of its first LRHW battery, as seen in the infographic below.
“It’s going to be a battery of four launchers, two missiles per for basic load of eight,” Bob Strider, Deputy Director of the Army Hypersonic Project Office, said at the annual Space and Missile Defense Symposium in August. “It’s going to be a Battery Operations Center — that’s our C2 system that is based against an AFATDS, the [Advanced] Field Artillery Tactical Data System …. with a support vehicle."
"This will be a road-mobile system, which is critical, the ability to move around the battlefield,” he added.
While we still don’t know the official designation for the initial LRHW unit, the latest photos reveal that at least some of the launchers have been given individual names, including Hyperion. In August, the Army had also revealed that it had given the name Dark Eagle to the forthcoming missiles that these launchers are intended to fire.
Back in March, when the Pentagon announced the delivery of the first two inert missile canisters, it was stated that “all additional ground equipment” for the LRHW prototype battery would also be delivered this year, suggesting that components at Joint Base Lewis-McChord may now constitute a complete system, with the exception of the missiles. Regardless of that fact, the prototype hardware delivered so far is intended for training use only.
It was previously reported that the Army anticipated tests of its prototype LRHW battery to start in Fiscal Year 2022, which began this October 1. The Army meanwhile plans to complete the fielding of a first operational battery, including live missile rounds, in Fiscal Year 2023.
While the Army has previously fielded ballistic missiles capable of hitting hypersonic speeds — generally classed as anything over Mach 5 — the LRHW, once in service, will be the service’s first purpose-built hypersonic weapon.
Development of the LRHW has involved the Army and the Navy, with the maritime branch using the same hardware in its Intermediate-Range Conventional Prompt Strike (IRCPS) weapon. While the launcher platforms for LRHW and IRCPS are different, the missiles themselves are the same, including a Common Hypersonic Glide Body, or C-HGB, and rocket booster.

In its statement on the prototype LRHW delivery, the Army says the weapon, once fielded, will “provide a unique combination of speed, maneuverability, and altitude to defeat time-critical, heavily defended, and high-value targets.” As far as speed is concerned, the Pentagon has previously said that the C-HGB will be capable of reaching a maximum speed of Mach 17. It also said it would be able to strike targets at a distance of at least 1,725 miles.
The maneuverability mentioned by the Army is another key attribute of new-generation hypersonic missiles, with the C-HGB able to make more unpredictable maneuvers, compared to traditional ballistic missiles, complicating an adversary’s ability to defend against it. The potential game-changing aspects of hypersonic weapons are something that The War Zone
has discussed in depth in the past.
The LRHW’s hypersonic capabilities are a critical part of the Army’s broader Long Range Precision Fires effort, or LRPF, which it describes as its “number one modernization priority.” Among others, this initiative aims to give artillery units a new long-range and deep-strike capability, including replacing the Army Tactical Missile System (ATACMS) now in use. ATACMS is a relatively small ballistic missile with a maximum range of around 190 miles and is set to be directly replaced by the Precision Strike Missile.
As The War Zone has examined in the past, hypersonic weapons, in general, are fast becoming seen as an important component of U.S. Indo-Pacific Command’s future warfighting strategies, above all to counter China’s expanding military capabilities in the region.
Earlier this year, the Pentagon submitted a plan to Congress outlining more than $27 billion in proposed spending over the next six years to bolster capabilities across the Pacific region to deter China. Fundamental to this Pacific Deterrence Initiative, or PDI, will be forward-deployed long-range strike capabilities. While these would include ground-based cruise missiles and ballistic missiles, hypersonic missiles — like LRHW – would be expected to play a central role.
The decision to base the first LRHW systems at Joint Base Lewis-McChord also speaks to the importance of this theater, the west coast location allowing the missiles to be rapidly positioned to contribute to future exercises or contingencies in the Pacific, including via the base’s resident C-17 airlifter fleet. Furthermore, the base is also home of the first Multi-Domain Task Force, another concept created with Pacific operations in mind, and which is ultimately intended to include a Strategic Fires Battalion equipped with HIMARS launchers and “mid-range” missiles, as well as LRHW.
However, the Army’s plans for fielding and employing LRHW develop, and regardless of where future batteries are deployed, the arrival of the first prototype launchers, and other hardware, at an Army installation is a critical step in the service’s path toward fielding hypersonic missiles.
