The M270 Multiple Launch Rocket System has been in service since 1983. It is a tracked rocket launcher, carrying up to 12 rockets. In 2010 a new more mobile wheeled version appeared known as HIMARS – this system carried up to 6 rockets. The standard ammunition for these systems is GMLRS rockets, which typically have a range of 70 km. Ukraine is using them too. But it is time for an upgrade.

Lockheed Martin, the manufacturer of HIMARS, reported successful tests of ER GMLRS rockets. This is quite important, because it will significantly improve the capabilities of these weapons, demand for which is growing.
GMLRS rockets, launched by the HIMARS and M270 systems, have a typical range of 70 km. However, Lockheed Martin has been developing a longer-range version of this rocket since 2017. ER GMLRS (ER – Extended Range) is exactly that. And new buyers of HIMARS will undoubtedly be very interested in these rockets, since their recent tests in New Mexico were successful and Lockheed Martin is moving towards series production of ER GMLRS rockets.
“The Army’s success in this operational test further demonstrates the readiness of ER GMLRS and overall capability of our family of munitions,” said Jay Price, vice president for Precision Fires at Lockheed Martin. “Our capabilities provide range options, affordability and of course the continued precision of this enhanced system.”
ER GMLRS will have a range of about 150 km. That is easily twice as far as the standard GMLRS. The manufacturer claims that both accuracy and reliability have been improved as well.
ER GMLRS in terms of its dimensions and launch mechanism is practically no different from its predecessors. This means that HIMARS launchers will not need any significant modifications. Overall, the advantage of the HIMARS and the M270 is their modular design. HIMARS can fire GMLRS rockets, which are smaller, or large, long-range tactical ballistic missiles ATACMS. There are also versions with cluster warheads.
The new rockets will be offered to existing HIMARS operators, but could also be supplied to countries that ordered HIMARS systems already after the Russian invasion of Ukraine. All Baltic countries are buying HIMARS now, as is Australia, Taiwan, Morocco, Italy. Of course, extended-range GMLRS rockets will also interest Poland, Ukraine, and other HIMARS users. Naturally, the US is going to be the first to use these rockets.
ER GMLRS doesn’t have the range or power of the ATACMS, but it is a much smaller rocket. Being able to engage targets 150 km away is very important, because that allows evading counter battery fire, staying away from enemy’s artillery and most drones. Such a reach advantage would be invaluable to Ukraine now, helping hit ammo warehouses and command posts deep behind the enemy lines.
The range and precision are two of the most important characteristics for tactical missiles. Hopefully, the ER GMLRS will soon reach production and will start its service.
