The document is an Engineering Change Order (ECO) from the Department of the Navy's NAVSUP Weapon Systems Support, concerning a modification to part 3321AS030-1, identified as a "Mount, Shear." Dated December 11, 2018, the ECO seeks to approve the H.A. King shock mount as an alternate source due to production delays and long lead times from the existing supplier. The new mount has successfully passed all required testing, justifying its approval for use. The document outlines the reasons for the change and the need for an alternate shock mount, while indicating that it does not affect the next higher assembly or overall system integrity. This ECO demonstrates a proactive approach to maintaining operational efficiency and contingency planning within the Navy’s supply chain management, ensuring that critical components remain accessible without compromising safety and compliance standards.

The Engineering Change Order (ECO) issued by the Department of the Navy's NAVSUP Weapon Systems Support aims to address the integration of a new shock mount part (H.A. King) as an approved alternative to the existing mount for the system identified as 3321AS030-2. The decision to permit the alternative comes in response to delivery delays and prolonged lead times encountered with the current manufacturer. The H.A. King mount is deemed qualified by similarity, as another model (3321AS030-1) has successfully met all testing criteria. This change seeks to enhance the logistical efficiency and reliability of supply chains for crucial components utilized in military applications. The ECO includes specific details such as part nomenclature, revision status, justification for the change, and signatures from the ECO originator and engineering check, ensuring compliance with protocol and traceability for modifications made in the procurement process.
