The LRHW is an intermediate-range missile launched from a trailer. Its predicted range is more than 1,700 miles. The device aims to reach a remarkably high speed of Mach 17, or 3.6 miles per second, which is considered “hypersonic.”

The watchdog noted that even with a successful launch, the service could encounter problems, indicating that further delays might occur. Service officials told the GAO that there could be more program delays due to concerns regarding missile performance during flight testing.

The gaps in the program are noteworthy since the US Army’s hypersonic program has been beset with controversies and delays for a while. In September 2023, the Army acknowledged that it would not meet its original goal of fielding the first battery by the end of the fiscal year 2023.

Since 2021, the LRHW has experienced several test failures, some of which have been attributed to missile malfunctions. According to the GAO, two tests in 2023 were canceled due to problems with the launcher and launch sequence.

Even though China and Russia have several hypersonic weapons, technological obstacles prevent the US from realizing its objective of possessing hypersonic weapons.

For instance, the US Air Force (USAF) had to officially cancel the AGM-183A Air-launched Rapid Response Weapon (ARRW) program after a spate of unsuccessful tests. The USAF has placed significant emphasis on developing the Hypersonic Attack Cruise Missile (HACM), yet the weapon is far from deployment.

Nonetheless, the LRHW has become a poster child of the US hypersonic program. In June, a U.S. Army unit assigned to the Indo-Pacific region and trained to combat anti-access area denial networks launched its first hypersonic missiles during a Navy-hosted exercise.

On June 25 and 27, the Bravo Battery of the unit’s Long-Range Fires Battalion showcased their ability to integrate and enhance the kill chain using the Dark Eagle or the Long-Range Hypersonic Weapon.

Moreover, the US Army awarded Lockheed Martin a $756 million contract to enhance the capabilities of the LRHW, the country’s ground-based hypersonic weapon system.

The US must resolve the technological problems and quickly implement a weapon, particularly in light of the growing threat posed by enemies (including state and non-state entities). Concerns are growing regarding the slow pace of research on hypersonic weapons, particularly in light of the significant advancements achieved by rival nations.
