Find items associated with a weapon system

Application path: Main Menu → Weapons System Designator Codes → choose Search by → enter a name or code → Search.

This screen connects a weapon-system description to its listed stock items. Use WS Name when you know the equipment name, or WSDC when you already know its Weapon System Designator Code.

Find a system by name, then use its code

Selecting WS Name and searching for helicopter returned 38 system rows across two pages in the October 21, 2026 example. Each row shows WSDC, WS Name and # of NIINs.

To focus on one of those systems, choose WSDC, enter 5ZA, and select Search. The result is AH64A HELICOPTER, with 16 listed NIINs. Select the arrow at the left of its row to expand the items.

You can also choose WS Name and enter AH64A. That search returns the same 5ZA — AH64A HELICOPTER row, with 16 NIINs.
