DA Form 5661 Guide: Support Equipment Data Interchange – If you’re a U.S. Army program manager, logistics officer, PEO/PM, or supply professional working with major systems and associated support equipment, DA Form 5661 is a critical document in the Army’s centralized inventory management process. Officially titled Data Interchange of Support Equipment Data, this form ensures that Component Major Items (CMI) and Associated Support Items of Equipment (ASIOE) are properly identified, funded, procured, and fielded on time.
In this comprehensive guide, you’ll learn exactly what DA Form 5661 is, when and why to use it, how to fill it out step-by-step, and where to download the latest fillable PDF directly from Army Publishing Directorate (APD). All information is drawn from official sources including AR 710-1 (Centralized Inventory Management of the Army Supply System) and the current form edition.
What Is DA Form 5661?
DA Form 5661 (dated OCT 2010, APD LC v1.00) is the standardized form used for the formal interchange of logistical data on support equipment between requiring commands (e.g., Program Executive Offices, Project Managers, or gaining commands) and procuring commands (Inventory Management Activities under U.S. Army Materiel Command).
- Proponent: Deputy Chief of Staff, G-4 (DCS, G-4)
- For use of this form, see: AR 710-1
- Previous editions: Obsolete
The form captures essential data such as nomenclature, National Stock Numbers (NSNs), Line Item Numbers (LINs), Life Cycle Costs (LCCs), delivery schedules, and approvals. It supports the Planning, Programming, Budgeting, and Execution System (PPBES) and ensures support equipment is integrated into the Total Army Equipment Distribution Program (TAEDP).
Why DA Form 5661 Matters in U.S. Army Logistics?
Support equipment (CMI and ASIOE) is often funded from the major system’s budget line and must be available when new equipment fields. Without timely data interchange:
- Procurement lead times slip.
- Fielding schedules are delayed.
- Excess or shortage of support items occurs.
DA Form 5661 bridges the gap between developers and the supply system. It is submitted:
- As soon as an item or major system appears in an approved requirements document (e.g., Operations Requirements Document).
- Annually by 1 November (with IMM response by 15 January).
- As interim changes whenever requirements shift.
This process guarantees that peculiar/unique support items receive priority under TAEDP and are correctly entered into the SSN X-REF file and Logistics Information Warehouse.
When to Use DA Form 5661? (Key Scenarios)
- New or modified major systems entering the Army inventory.
- Updates to Basis of Issue Plan for Field Deployment (BOIPFD).
- Changes in quantity, delivery dates, or funding for CMI/ASIOE.
- Coordination of Government Furnished Equipment (GFE) to contractors or field units.
- Support for Army Prepositioned Stocks (APS) or unit sets.
