How New NATO Rocket Launcher Compares to Ukraine's HIMARS

The U.S.-German defense collaboration between Lockheed Martin and Rheinmetall has unveiled the Global Mobile Artillery Rocket System (GMARS), a missile artillery system designed to significantly enhance NATO's firepower.

The advanced weapon is intended as a complement to the High Mobility Artillery Rocket System (HIMARS), which became a pivotal asset in Ukraine's arsenal during the summer of 2022, following Russia's initial invasion.

The American-made HIMARS has been crucial for Kyiv ever since. The U.S. has supplied at least 39 HIMARS systems to Ukraine since the war's onset. Each one can launch a salvo of six rockets, striking targets up to approximately 50 miles away, effectively reaching Russian troop formations, command centers and logistics nodes.

GMARS represents an evolution from HIMARS, featuring a larger HX 8x8 chassis that houses two rocket pods, thereby doubling the firepower available in a single mission. The primary distinction between the two systems lies in their launcher configurations.

GMARS's "shoot and scoot" capability is a vital enhancement, enabling rapid repositioning after firing to evade countermeasures, in contrast to the smaller, single-launcher profile of HIMARS.

Both systems emphasize mobility, utilizing wheeled platforms for quick battlefield deployment. GMARS's integrated crane also eliminates the need for additional support vehicles, enhancing operational readiness.

GMARS also surpasses HIMARS in technical specifications, boasting an operational range of up to 434.96 miles (700 kilometers) and a maximum speed of 62.14 miles per hour (100 km/h), compared to HIMARS's range of 186.41 miles (300 km) and top speed of 52.82 mph (85 km/h).

The boom-and-hoist system in GMARS improves its rapid emplacement capability, facilitating safe and swift reloading. Engineered to operate in all weather conditions, GMARS promises reliable and precise long-range accuracy, distinguishing it from its predecessor.

The system's design allows for unrestricted movement on standard roads and rail transport. GMARS operates with a minimal crew and offers optional cabin protection, maintaining a compact footprint without the need for outriggers, thus preserving its mobility and "shoot and scoot" advantage.

GMARS is more similar to HIMARS when it comes to munitions and logistics, ensuring seamless integration with NATO's existing infrastructure. Its compatibility with the MLRS Family of Munitions (MFOM) enhances its range and precision, reinforcing its strategic importance.

At the presentation of the system at Eurosatory 2024, a major European defense and security event, Rheinmetall chairman Armin Papperger said that the company is in discussions with "four or five potential European customers" for GMARS, though specific nations were not disclosed.

Recently, Germany announced the acquisition of three new HIMARS from the U.S. Armed Forces to support Ukraine in its ongoing conflict with Russia. The Pentagon has confirmed the delivery of another 40 HIMARS and associated ammunition as part of a $400 million aid package.
