DA Form 4379-1-SG: Missile & Rocket Malfunction Report

DA Form 4379-1-SG: Missile & Rocket Malfunction Report – The DA Form 4379-1-SG (Missile and Rocket Malfunction Report) is a critical U.S. Army document used to report malfunctions involving guided missiles and large rockets. This system-generated form ensures safety, supports investigations, and helps maintain operational readiness for U.S. forces.

Accurate and timely reporting prevents accidents, identifies defects in ammunition lots, and drives improvements in missile and rocket systems.

What Is DA Form 4379-1-SG?

DA Form 4379-1-SG is the current system-generated version of the Missile and Rocket Malfunction Report. It is prescribed for reporting all malfunctions involving guided missiles and large rockets (GMLR) assembled with nonnuclear warhead sections, along with separately packaged components required to assemble a complete missile or large rocket (except unassembled warheads).

It falls under AR 75-1, Malfunctions Involving Ammunition and Explosives. The form replaced or updated earlier versions like DA Form 4379-1-R and supports electronic submission through systems like the Munitions History Program (MHP).

Key Purpose:

  • Document incidents for investigation.
  • Track potential lot defects.
  • Support safety suspensions or restrictions on affected munitions.
  • Ensure compliance with Army explosives safety standards.

Why Proper Reporting Matters for Missile and Rocket Malfunctions?

Malfunctions can range from misfires and duds to more serious premature detonations or propulsion failures. Reporting via DA Form 4379-1-SG enables:

  • Rapid classification as Class A, B, or C (based on injury, damage, or mission impact).
  • Initiation of Department of the Army investigations when required.
  • Protection of personnel and equipment in training or combat environments.
  • Data collection for quality assurance and future procurement improvements.

U.S. Army units must report promptly to authorities such as the U.S. Army Aviation and Missile Command (AMCOM) at Redstone Arsenal.

When to Use DA Form 4379-1-SG?

Use this form specifically for guided missiles and large rockets. Conventional ammunition malfunctions use DA Form 4379 or 4379-SG instead.

Reportable Events Include:

  • Misfires or hangfires.
  • Duds (failure to detonate).
  • Abnormal functioning or premature explosions.
  • Propulsion or guidance system failures.
  • Any incident with potential safety or readiness implications.

Preliminary reports should go out immediately (often by phone or secure means), followed by the detailed DA Form 4379-1-SG submission.

Tips: Enter “NA” for non-applicable blocks. Provide as much detail as possible. Include photos, witness statements, and supporting data. Submit electronically when possible via MHP.

Consult your unit ammunition officer, QASAS (Quality Assurance Specialist, Ammunition Surveillance), or local safety office for assistance.

Submission and Distribution Requirements

  • Preliminary Reports: Immediate notification to appropriate commands (e.g., AMCOM for missiles/rockets).
  • Detailed Reports: Follow within days using the form.
  • Distribution: Primary to AMCOM or designated office; information copies to safety offices and higher commands.

For classified information, use secure channels.

  • AR 75-1: Primary regulation for malfunctions involving ammunition and explosives (updated as of 2023).
  • DA PAM 742-1: Ammunition Surveillance Procedures.
  • Unit safety SOPs and range regulations.
  • Munitions History Program (MHP) for electronic reporting.

U.S. Army personnel should receive training on these procedures during ammunition handling and range operations qualifications.

Best Practices for U.S. Army Units

  1. Train all personnel on malfunction recognition and immediate actions (cease fire, secure area, notify chain of command).
  2. Preserve evidence at the site for investigation teams.
  3. Integrate reporting into after-action reviews.
  4. Maintain records for trend analysis and lot tracking.
  5. Coordinate with EOD if unexploded ordnance is involved.

Stay Safe and Compliant: Proper use of DA Form 4379-1-SG protects lives, enhances mission effectiveness, and upholds the highest standards of Army ammunition safety.
