TheLong-Range Hypersonic Weapon (LRHW)is amedium-rangesurface-to-surfacehypersonic weaponbeing developed for use by theUnited States Army.TheUnited States Navyintends to procure a ship/submarine-launched variant of the missile as part of the service'sIntermediate-Range Conventional Prompt Strike (IRCPS)program.[2]The weapon consists of a largerocket boosterthat carries the unpowered Common-Hypersonic Glide Body (C-HGB) in a nose cone. Once the booster reaches significant altitude and speed, it releases the C-HGB, which glides at hypersonic speeds as it descends towards its target.Dyneticswill build thehypersonic glide vehiclewhileLockheed Martinwill build the booster as well as assemble the missile and launch equipment.[8]

The C-HGB has been successfully tested twice, in October 2017 and March 2020.[9][10]The missile is planned to enter service with the Army in 2023.[11]The Navy intends to field the weapon aboard itsZumwalt-class destroyersby 2025[11]and later on its Block VVirginia-class submarines[12]in 2028; it was intended to also be fielded on guided missile variants of theOhio-class ballistic missile submarines,but funding delays and the boats' impending retirement caused those plans to be scrapped.[13]

Development and testing[edit]

Common-Hypersonic Glide Body[edit]

In 2018, the Navy was designated to lead the design of the Common-Hypersonic Glide Body with input from the Army's Rapid Capabilities and Critical Technologies Office.[14]

Design[edit]

The design of the Common-Hypersonic Glide Body is based on the previously developed Alternate Re-Entry System, which was tested in the early 2010s as part of the Army's Advanced Hypersonic Weapon program.[15][16]The Alternate Re-Entry System was itself based on the Sandia Winged Energetic Reentry Vehicle Experiment (SWERVE) prototype developed bySandia National Laboratoriesin the 1980s.[17]Design work is by Sandia whileDyneticsconstructs prototypes and test units.

Testing[edit]

The first test of the Intermediate Range Conventional Prompt Strike Flight Experiment-1, was on 30 October 2017. A missile capable of fitting in the launch tube of anOhio-class ballistic missile submarineflew over 2,000 nautical miles from Hawaii to the Marshall Islands at hypersonic speeds.[18]The Common-Hypersonic Glide Body was tested in March 2020.[9][10]

LRHW subsystems were tested at Project Convergence 2022 (PC22).[19][20]

Boosters[edit]

The first stage solid rocket motor was tested 27 May 2020.[21]

Both stages of the missile booster as well as a thrust vector control system were tested in 2021.[22][23]

On 29 October 2021, the booster rocket for the Long-Range Hypersonic Weapon was successfully tested in a static test in Utah; the first stage thrust vector control system was included in the test.[24]

In March 2021, training with inert missile canisters began.[1]On 7 October 2021,17th Field Artillery Brigadeof theI Corpsreceived ground equipment for the first operational LRHW battery.[25]

In June 2022 inHawaii,a launch failure of Conventional Prompt Strike occurred after ignition.[26]The test of a completely assembled CPS weapon, which uses a two-stage booster,[27]failed before ignition of the C-HGB.[28]

Entry into service[edit]

TheUnited States Armyintends to deploy the Long-Range Hypersonic Weapon in an eight missilebatterycontaining fourM983trucks and trailers each holding two missiles in launch canisters alongside a command vehicle.[9][10]The LRHW has been namedDark Eagleby the US Army.[29][30][31]

In February 2023, the 5th Battalion,3rd Field Artillery Regiment(5-3 LRFB) — 1st MDTF's long-range fires battalion— deployed the LRHW fromJoint Base Lewis-McChord,Tacoma, Washington toCape Canaveral,Florida. The first battery of missiles was expected to be deployed by end of September 2023.[32]

On 7 September 2023, a test launch of the LRHW system was canceled due to an unspecified failure of pre-flight checks.[33][34][35]Douglas R. Bushrevealed that the launcher had a "mechanical engineering problem", and that a new plan was in place to correct and test it.[36][37][38]
