What Is DA Form 2408-4-2?
DA Form 2408-4-2, titled “Weapon Sighting Data (OH-58D)”, is part of the Army Maintenance Management System – Aviation (TAMMS-A). It records data constants and sighting information for the OH-58D’s Mast Mounted Sight (MMS) components, which integrate sensors and weapons systems.
For use of this form, see DA PAM 738-751; the proponent agency is DCSLOG (now under broader Army logistics oversight). The form was issued in OCT 91 (with OCT 1997 updates noted on some versions), and earlier editions may still be used.
It pairs with related forms like:
- DA Form 2408-4-1 (Weapon Record Data)
- DA Form 2408-4-3 (for AH-64 Apache)
Purpose of the Weapon Sighting Data Form
The primary purpose of DA Form 2408-4-2 is to maintain precise data constants and serial number records for MMS components. This ensures boresighting, calibration, and weapon delivery accuracy for the OH-58D Kiowa Warrior.
Key functions include:
- Recording MMS component details (Upper/Lower Shroud, TVS, TIS, etc.)
- Tracking data constants for sighting alignment
- Supporting maintenance and historical records for weapon systems integration
- Ensuring safety and accuracy in engagements with weapons like the .50 cal machine gun, 2.75″ rockets, Hellfire missiles, and Stingers
Accurate records help crews and maintainers verify alignment between the mast-mounted sensors (thermal imaging, TV, laser rangefinder/designator) and the aircraft’s weapons.
OH-58D Kiowa Warrior Context
The OH-58D Kiowa Warrior is a single-engine, two-place armed reconnaissance helicopter famous for its distinctive Mast Mounted Sight (MMS). This system houses thermal imaging, low-light TV, laser rangefinder/designator, and optical boresight capabilities, enabling standoff target acquisition in day, night, and adverse weather.
Weapons capabilities typically included combinations of Hellfire missiles, Air-to-Air Stingers, 2.75-inch rockets, and .50-caliber machine guns. The form specifically supports sighting data for these integrated systems.
Note on status: The US Army fully retired the OH-58D fleet around 2017 as part of the Aviation Restructure Initiative, transitioning roles to AH-64 Apaches and unmanned systems. The form remains relevant for historical records, museums, foreign operators (e.g., transferred aircraft), training, or reference.
