HIMARS Rocket Launcher: 96-Launcher Buy, Costs and Combat Record
HIMARS rocket launcher explained: what it fires, the Army’s request for 96 launchers in FY2027, rocket contracts and its record in Ukraine.
The M142 High Mobility Artillery Rocket System, or HIMARS, is a wheeled rocket launcher. The HIMARS rocket launcher has become one of the most closely watched weapons of the war in Ukraine, and the U.S. Army is now asking to buy it in far larger numbers. The Army’s fiscal 2027 budget request asks for 96 launchers, up from six in fiscal 2026. A longer-range rocket for it has also just been cleared for production. This guide covers what HIMARS is, what it fires, what it costs and where it has been used.
What HIMARS is and what it does
HIMARS is a truck-mounted launcher. It was introduced in the late 1990s as a lighter alternative to the tracked M270 Multiple Launch Rocket System (MLRS), according to the Congressional Research Service (CRS). Its job is long-range precision fire: hitting command posts, ammunition depots, air defenses and other targets well behind the front line, then driving away before the enemy can fire back.
The launcher carries one pod of munitions. The tracked M270 carries two. A 2021 CRS report explains that 227mm rockets come six to a pod, while the larger missiles come one to a pod.
What it fires: official figures
| Munition | Per HIMARS load | Range | Source |
|---|---|---|---|
| GMLRS guided rocket | 6 | Up to 150 km (CRS 2024 figure) | CRS R48182, R46721 |
| Extended-Range GMLRS | 6 | Up to 150 km | Lockheed Martin, Oct. 19, 2026 |
| ATACMS ballistic missile | 1 | About 300 km | CRS R46721, R48182 |
| Precision Strike Missile (PrSM) | Not stated in the CRS reports | Objective of more than 500 km | CRS R46721 |

The 2021 CRS report says the guided rocket carries a 200-pound unitary warhead. It also notes that while the Intermediate-Range Nuclear Forces Treaty was in force, Army missiles were capped at 499 km. PrSM, now in production, was designed after that cap ended.
Production and cost
The Army’s fiscal 2027 Missile Procurement justification book, dated April 2026, lists HIMARS as budget line 17. A summary of the Pentagon comptroller’s P-1 exhibits compiled by AwardTape shows how sharply the buy changes:
| Fiscal year | Launchers | Funding |
|---|---|---|
| FY2025 (actual) | 18 | $175.5 million |
| FY2026 (enacted) | 6 | $61.5 million |
| FY2027 (request) | 96 | $745.7 million |
Peter’s World table from DoD Comptroller P-1 data as compiled by AwardTape (built Oct. 16, 2026).
Dividing the request by the quantity gives about $7.8 million per launcher, including support costs. That is a Peter’s World calculation, not a figure the Army publishes as a unit price.
Munitions are the larger bill. In October 2024 the Army announced a guided-rocket contract with Lockheed Martin worth up to $4.1 billion, covering both standard and extended-range rockets. “The award is intended to be definitized as part of a three-year multiyear contract,” Douglas Bush, then the Army’s acquisition chief, said in the Army’s announcement.
Output has climbed since 2022. According to the 2024 CRS report on defense production for Ukraine, the Defense Department said it was producing 8 HIMARS launchers a month, or 96 a year, in September 2024, up 60% from 2022. It put guided-rocket output at about 14,000 a year, up 40%.
Users and combat record
The Defense Department announced in June 2022 that it would send HIMARS to Ukraine, and at least 40 launchers had been provided by September 2024, according to CRS. Ukraine has used the system against Russian logistics and command targets, and with ATACMS against deeper targets. Exact battle damage figures are not published by either government, so Peter’s World does not repeat claimed totals.

Recent news
On Oct. 19, 2026, Lockheed Martin said the Army had approved Milestone C for the extended-range rocket. That is the formal step that clears a weapon for production and fielding. The company said soldiers completed two operational tests in September and October at White Sands Missile Range, New Mexico, firing the alternative-warhead and unitary versions from an M270A2 launcher.
How it compares
| System | Chassis | Load | Longest-range munition |
|---|---|---|---|
| M142 HIMARS (U.S.) | Wheeled truck | One pod | PrSM (see table above) |
| M270A1/A2 MLRS (U.S. and allies) | Tracked | Two pods, so double the load | Same munitions family |

Peter’s World’s view
Analysis: Peter’s World interpretation of the sources above.
The budget tells the story. After years of buying a handful of launchers, the Army is asking for 96 in one year, the same number DoD said industry could build annually in 2024. In our view, that suggests the service wants to buy at the line’s full rate rather than keep it ticking over. The weak point is ammunition rather than trucks. A launcher holds only six guided rockets, so sustained use depends on the rocket contracts and the extended-range rocket reaching units on time.
What to watch
- Whether Congress funds the full 96-launcher request in the fiscal 2027 defense bill.
- When the Army definitizes its multiyear guided-rocket contract and sets delivery rates for the extended-range version.
- Any new HIMARS or rocket transfers announced for Ukraine, and replacement buys for U.S. stocks.
- PrSM deliveries, which would give HIMARS units their longest reach.
