HIMARS Rocket System Overview

Overview

This lecture covers the design, specifications, and operational tactics of the HIMARS rocket system, emphasizing the role of precision missiles and coordination with F-35 fighter jets.

HIMARS Overview & Specifications

• The M142 High Mobility Artillery Rocket System (HIMARS) is a lightweight, mobile rocket launcher developed for the U.S. Army in the late 1990s.
• HIMARS is mounted on a medium tactical vehicle (M1140 truck frame) and is lighter than the M270 system.
• HIMARS carries one missile pod, while the M270 carries two.
• The system includes a fire control system (FCS) for computing fire missions and a launcher loader module (LLM) for executing tasks.
• Vehicle dimensions: length 7 m (23 ft), width 2.4 m (7 ft 10 in), height 3.2 m (10 ft 6 in), weight ~10,886 kg.
• Operated by a crew of three (driver, gunner, commander); FCS allows operation by as few as one soldier.

Operational Tactics & Launch Sequence

• HIMARS is transported by Lockheed C-130 Hercules aircraft and operational within 15 minutes of landing.
• After unloading, the HIMARS unit moves up to 70 km (40 miles) near front lines.
• Targets are designated by command and control centers.
• Features “shoot and scoot” tactics to evade enemy detection and enhance survivability.
• Reloading is rapid, using a reload arm assembly for up to six rockets of varying calibers.

Precision Missile & F-35 Coordination

• F-35 jets conduct reconnaissance and identify multiple enemy targets up to 300 km away.
• F-35s use electronic suites to send coordinates to combat operations centers.
• HIMARS battalions receive target information and prepare for rapid missile deployment.
• Precision Strike Missile (PrSM) by Lockheed Martin: length 156 in, diameter 17 in, uses GPS for guidance.
• PrSM features pre-formed fragments in its warhead to increase lethality and area effects.
• The missile’s design allows for future upgrades (additional warheads or software).
• Missiles are launched in quick succession for surprise, guided to separate targets via GPS.

Key Terms & Definitions

• HIMARS — High Mobility Artillery Rocket System; a lightweight, mobile multiple rocket launcher.
• FCS — Fire Control System; computer system for targeting and firing operations.
• LLM — Launcher Loader Module; component handling rocket loading and launching.
• C-130 Hercules — Military transport aircraft used to deploy HIMARS.
• PrSM (Precision Strike Missile) — GPS-guided missile developed by Lockheed Martin for high accuracy and lethality.
