Furthermore, the file contains a distribution statement indicating restricted access to authorized Department of Defense (DOD) personnel and contractors, underscoring the critical military applications of the technical data. The document serves as a technical data package integral to military procurement and manufacturing processes, ensuring that vendors comply with stringent standards in producing essential defense components.

The document outlines technical specifications and engineering details for the design of a component called the "Ring, Obturation" used in various military applications by the US Army's Armament Research, Development and Engineering Center located at Picatinny Arsenal, New Jersey. It includes essential design elements such as dimensions, tolerances, material requirements, and mechanical properties required for production. Key references include specifications from ASTM, ASME, and military standards that pertain to the manufacturing processes, material properties, and quality control measures. The drawing also lists the necessary heat treatment processes and dimensional accuracy parameters essential for ensuring the part’s functionality and reliability in military equipment. The document is intended for use by government and defense contractors, with distribution restricted to specific authorized personnel, highlighting its critical importance to national defense applications.

This document outlines the technical specifications and design details for an obturating ring, primarily intended for use in a new weapons system by the U.S. Army's Armament Research, Development and Engineering Center. It includes critical information such as dimensions, tolerances, applicable standards, material specifications (polycarbonate), and mechanical properties governed by various ASTM standards. The drawing emphasizes that dimensions are in inches and provides detailed notes on surface finish, mold marks, and performance under testing conditions. The distribution of this technical data is restricted to the Department of Defense and its contractors, highlighting the sensitive nature of the technology described. The document stresses the government’s unlimited rights over the data contained within and outlines responsibilities relating to copies and modifications. It is part of a structured approach to ensure compliance with federal regulations regarding military specifications and technical documentation.

The document outlines the process for accessing Technical Data Packages (TDPs) associated with a government solicitation, specifically concerning restricted and export-controlled data. Vendors must register for a Sam.Gov account to access any TDPs electronically, which can be found on the Contracting Opportunities section of the site. The procedure varies for unrestricted and restricted TDPs; the latter requires valid contractor credentials and may necessitate government approval. Access to export-controlled TDPs also demands a current Defense Logistics Information Service (DLIS) DD 2345 agreement. Upon completion of their intended use, contractors are required to securely destroy all copies of restricted data. This protocol ensures that sensitive information is handled appropriately and in compliance with legal regulations. Additionally, vendors are reminded to maintain accurate account information on Sam.Gov, with resources and support available for registration inquiries. Overall, the document stresses the importance of regulatory compliance in accessing and managing restricted technical data.

The Army Contracting Command – Rock Island (ACC-RI) has issued Solicitation W519TC-25-R-2003 for the procurement of Obturating Rings in various sizes (60MM, 81MM, and 120MM) under a Single Firm Fixed Price (FFP) contract, set aside exclusively for small businesses. The solicitation encompasses specific quantity requirements for each size, including First Article Test samples and certification needs, with strict stipulations against using recycled materials. Deliveries are set to occur 30 days post-approval of the First Article Test for selected line items, with a defined delivery address at Pine Bluff Arsenal in Arkansas. Offerors must comply with standards for packaging, marking, and must possess registration in the System for Award Management (SAM) for eligibility. Proposals are required to be submitted electronically, adhering to a deadline, and must remain valid for 60 days post-submission. This opportunity underscores the government's commitment to sourcing from qualified small businesses, ensuring procurement aligns with established regulations and standards.
