About this file
This document is a draft scope for a Special Notice from the Army Contracting Command - Detroit Arsenal (ACC-DTA) regarding a future solicitation for a Self-Propelled Howitzer Modernization Evaluation. The government is seeking industry feedback on the draft Scope of Work and attachments to help create an appropriate and reasonable requirement.
The key details include:
- The government is not seeking quotes, bids, or proposals at this time, but is interested in feedback on the draft scope, including the timeline from award to delivery, personnel required, testing that could be reduced or eliminated, willingness to provide 3D CAD models and ported cannon tubes, and any export administration issues.
- The government is interested in collecting lightweight 3D CAD models for internal use and information on ported cannon tubes that could be used.
- The draft Scope of Work and attachments provide details on the required products and services, test support assumptions, and required Contract Data Requirements List (CDRL) deliverables.
- Responses to the Special Notice are due by 5 p.m. Eastern Standard Time on 5 December 2024.

VehDyn UID
| Underside Impact Detection (UID) Profile - Geometry Bottom Profiles: "Ground clearance of the vehicle along the vehicle length" |
| NOTE: The standard UID data file models the section of the vehicle along which the wheels are located, describing the underside between the wheels, ahead of the first wheel and behind the last wheel. |
The reference point is: 1) pintle or fifth wheel for wheeled vehicles, 2) centerline of rear sprocket/idler for tracked vehicles. X measurements begin at the FRONT of a vehicle. X value at reference point thus is zero. All trailer values are negative. All Z values are measured from the ground for the tire deflection cases for Mud/Sand/Snow and other off-road cases. X is longitudinal, Z is vertical.
