GMLRS Rocket Production 2026: US Manufacturing Surge and Ukraine Supply
The Guided Multiple Launch Rocket System (GMLRS) — fired from HIMARS and M270 launchers — became Ukraine's most strategically significant precision munition after first deliveries in June 2022. Long-range precision strike enabled Ukraine to disrupt Russian logistics, supply depots, command posts, and bridging equipment at unprecedented range and accuracy. But the war's industrial logic became quickly apparent: sustaining GMLRS supply required a production surge the US defense industrial base was not prepared for.

GMLRS Background
The M270 MLRS entered US service in 1983 as a conventional artillery rocket system with unguided rockets. The transformative innovation came with the M31 Guided Multiple Launch Rocket System (GMLRS), which added GPS+INS terminal guidance to the 227mm rocket, achieving 2–5m CEP at 70km range — a precise artillery strike at previous air-delivered bomb accuracy.
GMLRS has been in combat use since 2007 (Iraq, Afghanistan) and proved decisive in counter-IED targeting, mobile strike, and logistics interdiction. The M270 launcher carries 12 GMLRS per reload pack (two 6-round pods), while the lighter M142 HIMARS carries 6 (one pod).
Ukraine Operational Debut 2022
The US provided Ukraine with M142 HIMARS launchers and GMLRS rockets beginning in June 2022, following weeks of Ukrainian pressure for long-range precision strike capability. The operational impact was rapid and decisive:
- Russian ammunition depots: Ukraine struck a series of Russian MLRS and artillery ammunition depots in Luhansk, Kherson, and Zaporizhzhia oblasts within 70km of front lines. Several major depots were destroyed, temporarily reducing Russian artillery volume by an estimated 20–30%.
- Bridging and crossing points: Ukrainian strikes on pontoon bridges and river crossings in Kherson oblast repeatedly disrupted Russian logistics, hindering the ability to reinforce Russian troops on the west bank.
- Command and control nodes: Russian headquarters, mobile command posts, and communications hubs were being struck at previously untouchable distances, complicating Russian C2.
By July–August 2022, US and Ukrainian officials reported Russia had moved its most critical logistics nodes beyond 70km of the front specifically to escape HIMARS range — an operational adaptation that lengthened Russian supply lines significantly.
US Production Surge
Pre-war Lockheed Martin GMLRS production at Camden, Arkansas ran approximately 5,000–6,000 rockets per year — calibrated for standard US Army peacetime consumption plus modest allied sales. Once Ukraine's consumption rate became clear (200–400 rockets per month in active combat phases), the DoD recognized this was approaching or exceeding production output.
US actions to surge production:
- Multi-Year Procurement (MYP) contracts: DoD awarded Lockheed Martin multi-year GMLRS contracts in 2022 and 2023, providing production predictability and enabling capital investment in expanded manufacturing lines at Camden.
- Defense Production Act (DPA) investments: Title III DPA funds invested in supplier base capacity — specifically rocket motor production (solid fuel), guidance components, and warhead manufacturing, all of which had sub-tier bottlenecks.
- Three-shift operations: Camden facility moved from two-shift to three-shift operations in 2022–2023, roughly increasing throughput by 50% without new capital investment.
- Subcontractor vertical integration: Lockheed added manufacturing capacity rather than relying on sole-source suppliers for guidance electronics components.
The production target set by the DoD was 14,000 GMLRS rounds per year — more than double pre-war production. Industry reports suggest actual rates in 2025 approached 10,000–12,000 per year, with continued ramp through 2026.
US GMLRS Production Capacity Over Time
| Period | Production / Target | Key Changes | Ukraine Deliveries (est.) |
|---|---|---|---|
| Pre-2022 (baseline) | ~5,000–6,000/yr | Standard peacetime rate | None |
| 2022 (H2, war start) | ~6,000–7,000/yr (ramping) | Third shift added; MYP contract awarded | ~500–1,000 (initial tranche) |
| 2023 | ~8,000–10,000/yr | DPA investment flowing; new production lines online | ~3,000–4,000 |
| 2024 | ~10,000–12,000/yr | Full expanded capacity operational | ~4,000–5,000 |
| 2025–2026 (target) | ~12,000–14,000/yr | Full DoD surge target achievement | ~5,000+/yr (if politically approved) |
GMLRS Variants
| Variant | Designation | Warhead | Range | Guidance | Ukraine Use |
|---|---|---|---|---|---|
| GMLRS Unitary | M31A1 | 90kg blast-frag (unitary) | 70 km | GPS+INS | Yes — point targets |
| GMLRS Alternative Warhead | M30A1/A2 | 182 tungsten balls (no duds) | 70 km | GPS+INS | Yes — area suppression |
| GMLRS Extended Range (ER) | M31A2 / ER variant | Unitary or AW | ~150 km | GPS+INS | Limited; approved for Ukraine |
| ATACMS (MGM-140) | M39/M57 | Unitary / submunition | 165–300 km | GPS+INS | Yes — since Oct 2023 (limited) |
GPS Jamming Challenge in Ukraine
Standard GMLRS relies heavily on GPS for terminal guidance. Russia has deployed dense GPS jamming in contested areas of eastern Ukraine, including Pole-21 GNSS jammers, Krasukha-4 broadband EW complexes, and vehicle-mounted GNSS suppression systems at battery and brigade level. In heavily jammed corridors, GPS-guided munitions including GMLRS experience varying degrees of accuracy degradation:
- Mild jamming environment: GPS jitter but INS backup holds; CEP increases to ~10–20m — still operationally effective against most target types
- Heavy jamming environment: GPS denied; pure INS drift degrades CEP to ~50–200m — effective against large targets (depots, bridges) but insufficient for vehicle-level precision
- Countermeasures: The US has developed and fielded GPS anti-jam receiver upgrades for GMLRS. Some rounds have been retrofitted with improved ECCM receivers. Lockheed's GMLRS+ upgrade includes M-code GPS compatibility (military-encrypted, harder to jam) for future-production rounds.
Relationship to ATACMS
GMLRS at ~70km range was transformative in 2022 but insufficient as Russia moved logistics further back. The natural next step — ATACMS (Army Tactical Missile System) at 165–300km range — was politically sensitive due to concerns about deep strikes into Russia. ATACMS deliveries began in October 2023, initially with older M39A1 (300-unit submunition) variants being quietly included in packages, then later with longer-range M57 (unitary) variants.
GMLRS and ATACMS are complementary: GMLRS for the tactical-operational zone (30–70km), ATACMS for operational-strategic depth (70–300km). The GMLRS Extended Range (ER) variant at ~150km fills the gap between standard GMLRS and ATACMS, and the US approved delivery of GMLRS-ER to Ukraine in 2024.
Key Target Sets in Ukraine
GMLRS in Ukraine has been employed against:
- Ammunition storage points (ASPs): Secondary explosions visible from satellites validated destruction of multiple large Russian depots. Each successful strike can set back Russian ammunition supply for days to weeks in a given sector.
- Field command posts (CP): Temporary CPs within 70km, including battalion and regimental command nodes. Killed and disrupted Russian command relationships at critical moments (Kherson operaiton, Kharkiv counteroffensive).
- River crossings and bridges: Particularly decisive in Kherson oblast — repeated HIMARS strikes on the Antonivsky Bridge and pontoon crossings cut Russian logistics, contributing to November 2022 withdrawal.
- Air defense radar sites: Several Russian SAM radar systems (S-300/S-400 acquisition radars) struck by GMLRS at extended ranges.
- Logistics hubs and train stations: Rail transfer points, fuel storage, and vehicle staging areas.
March 2026 Status
As of March 2026, the GMLRS supply situation has significantly improved from the acute shortages of 2022–2023. Key status points:
- Production rates: Approaching 12,000–14,000/year, substantially above pre-war baseline, though still constrained vs wartime consumption
- Delivery volumes: Consistent packages of 2,000–4,000 GMLRS per authorization cycle
- GMLRS-ER expansion: Longer-range variants increasingly included, expanding strike depth
- GPS ECCM upgrades: A portion of Ukraine's rounds include improved anti-jam receivers
- Allied production: UK and Australia also produce GMLRS and have contributed to Ukraine packages, supplementing US output
- US stockpile concern: DoD continues to balance Ukraine deliveries against maintaining US Army readiness stockpiles, creating periodic delivery gaps
