Why HIMARS Didn’t Win the War in Ukraine

The M142 High Mobility Artillery Rocket System, a modular platform capable of launching guided precision munitions and ATACMS tactical ballistic missiles, has seen its battlefield effectiveness sharply diminished due to Russian military adaptations, according to assessments by former Ukrainian military leadership. Deployed to Ukraine in the summer of 2022 to widespread acclaim, the American-made rocket launcher was initially credited with executing surgical strikes on enemy command posts and supply nodes before widespread electronic warfare and drone tracking altered its operational reality.

The Initial Impact and Global Rise of HIMARS

When the M142 HIMARS arrived in Ukraine, it immediately altered the artillery calculus along the front lines. According to the then-commander of the Ukrainian Armed Forces, General Valery Zaluzhny, the timely arrival of the systems served as an important factor in maintaining defensive lines by carrying out surgical strikes on enemy command posts, ammunition depots, and fuel hubs. Videos of successful GMLRS missile strikes circulated widely, boosting the weapon’s global profile and prompting NATO nations—including Poland, Estonia, Lithuania, and Latvia—to place sequential orders for the platform.

How Russian Forces Found an Antidote

Operational conditions for the rocket system shifted dramatically as Russian forces adapted their electronic warfare and tactical positioning. Reports surfaced in May 2023 indicating that Russian electronic-warfare systems were effectively blocking the GPS signals of GMLRS missiles, causing munitions to lose their intended accuracy. Furthermore, Russian forces improved tracking of HIMARS launchers near the front lines—areas the systems must approach to execute deep strikes given their range limitations—while relocating command posts farther back to remain out of reach. According to General Zaluzhny, cited by The Ukrainian Review, Kherson was initially liberated with HIMARS, but a month later the systems “turned into, well, a useless thing that was simply impossible to use” as adversaries mapped out launch tactics and predicted arrival points.

Frontline Losses and Current Operational Status

The accumulation of electronic jamming and drone-based detection translated directly into verifiable equipment losses for the Ukrainian military. On February 10, 2024, two damaged Ukrainian HIMARS launchers arrived at Harrisburg International Airport in Pennsylvania aboard an An-124-100M transport aircraft. The following month, visual and official confirmations established that Ukraine had lost its first HIMARS system, with a second and third unit subsequently destroyed or damaged by Russian drone strikes. While Ukraine continues to employ the platform when specific opportunities arise, General Zaluzhny stated that Russia has ultimately found an antidote to every NATO system tested in the conflict, leaving Ukrainian drones as the primary effective operational countermeasure.

Frequently Asked Questions

What is the M142 HIMARS?

The M142 High Mobility Artillery Rocket System is an American-made, wheeled multiple-launch rocket system capable of firing guided precision rockets and ATACMS tactical ballistic missiles.

Why did the effectiveness of HIMARS change over time?

According to former Ukrainian commander General Valery Zaluzhny, Russian forces adapted by deploying advanced electronic warfare to jam GPS signals, tracking launchers near the front lines, predicting firing tactics, and moving command posts further out of range.

Has Ukraine lost any HIMARS launchers?

Yes. Following damaged units arriving in Pennsylvania in February 2024, confirmations followed that Ukraine lost its first HIMARS system in March 2024, with subsequent reports noting additional units damaged or destroyed.
