M142 HIMARS

Wheeled, truck-mounted rocket artillery system that fires the same GMLRS rockets and ATACMS missiles as the tracked MLRS but with a lighter, air-transportable chassis. Gained international prominence in the war in Ukraine.

In service since 2005 · 12 operator countries

Procurement snapshot

Availability & export

US ITAR-controlled

Export needs U.S. State Dept (DDTC) approval; end-use & re-transfer restrictions apply.

Channel: Foreign Military Sales (FMS) or Direct Commercial Sale

Fielded & proven

Established · 12 operators

In service since 2005. Status: active · ~540 built.

Lifecycle cost (est.)

$13M – $18M

Acquisition is only ~30% of lifecycle cost — operating & support dominate over ~25 yrs. Rough 2.5–3.5× the unit price.

Interoperability

No standardised NATO calibre / datalink detected in public specs.

Derived guidance from public data — export regime by country of origin, lifecycle from the GAO ~30% acquisition rule. Verify eligibility, pricing and offsets with the manufacturer and your acquisition authority.

Full specifications

Performance

Speed, range, altitude and engagement capability.

Max speed

Maximum level speed. For aircraft this is at optimal altitude; for ground vehicles, top road speed. Higher means faster response and better kinematic performance.

85 km/h
Stronger than 73% of artillery systems
Range

Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence.

480 km
Stronger than 34% of artillery systems

Firepower

Armament, payload and guidance.

Main armament

Primary weapon: main gun, cannon or missile type.

6x GMLRS rocket pod or 1x ATACMS/PrSM missile
Ammunition

Rounds carried (main gun) or standard magazine capacity.

6
Stronger than 16% of artillery systems
Max firing range

Maximum range of the main gun or rocket artillery (with assisted/extended-range munitions where noted). Higher extends reach.

300 km
Top 6% of artillery systems

Physical

Dimensions, weight and crew.

Length

Overall length including gun/probe where applicable.

7 m
Width

Overall width — matters for rail/road transport of vehicles.

2.4 m
Height

Overall height. Lower profile is harder to spot and hit for ground vehicles.

3.2 m
Combat weight

Fully loaded weight. Lighter eases transport and bridging limits; heavier often means more armor.

16,257 kg
Crew

Personnel required to operate. Fewer reduces exposure; autoloaders trade a loader for mechanical complexity.

3

Propulsion

Engine, power and fuel.

Engine

Powerplant model and type.

Caterpillar C7 diesel
Propulsion type

Turbofan, turboshaft, diesel, gas turbine, solid-fuel rocket, ramjet…

Diesel, 6x6 wheeled truck chassis

Program

Cost, production scale and operators.

Unit cost

Approximate flyaway/unit cost where public. Defense pricing varies hugely by contract, offsets and configuration. Lower is cheaper.

$5,100,000
Units built

Total production run. Higher means proven manufacturing, mature logistics and spares availability.

540
Stronger than 55% of artillery systems
Operator countries

Number of countries operating the system. More operators means broader support ecosystem.

12
Stronger than 85% of artillery systems
