Getting MLRS guided rockets in either M142 HIMARS wheeled or M270 tracked launchers represents a phase shift increase in artillery capability for Ukraine.👇

American Guided MLRS artillery rockets are a combat proven precision guided weapon (thousands fired) with a 200lb (90.7kg) insensitive explosive warhead equipped with multi option fuzing that is set electronically.

They use GPS & inertial guidance for 3 meter accuracy.

Both the US move away from cluster munitions & the 30 year rocket age have seen early MLRS unguided rockets disposed of.

And while pilot quantities of GMLRS were built with cluster munitions in the early 2000's. Most (>99%) GMLRS built have unitary warheads.

To restore lost lethality of cluster munitions against radars, towed artillery & missile launchers in peer combat, a modified version of GMLRS has been given a much improved fragmentation warhead.

This "Alternate Warhead" will be available for GMLRS ammo shipments to Ukraine.

Given the bad memories of losing soldiers to unexploded M26 rocket cluster munitions in 1991's Desert Storm operations. The US Army spend a lot of money to make the GMLRS fuze as reliable as possible, in addition to being multi-option.

It functioned 74/75 times in testing.

It is accurate to say that the arrival of GMLRS missiles, and their launchers in numbers similar to the M777, in Ukraine's hands will overwhelm both Russian artillery and the railway logistics it in the Donbas.

The USA has over 40,000 GMLRS missiles available in stock.

This is the Lockheed-Martin video celebrating the 50,000th GMLRS produced.

The recent lot 14 production award was for 9,500 GMLRS unitary and alternative-warhead (AW) rockets and over 300 low-cost reduced-range training rockets.
