T9074-AD-GIB-010/1688 (REV. 1), NAVSEA TECHNICAL PUBLICATION: REQUIREMENTS FOR FABRICATION, WELDING, AND INSPECTION OF SUBMARINE STRUCTURE (13-JUL-2012) [SUPERSEDING MIL-STD-1681 AND MIL-STD-1688]., The ORIGINAL issue of this document replaced MIL-STD-1688A, MIL-STD-1681, and, for submarine applications only, MIL-STD-1689A. It combines in one publication all requirements for fabrication, welding, and inspection of submarine structure. This Revision (Rev 1) updates the ORIGINAL issue and incorporates new technical developments, such as requirements for HSLA-80/100 steels, and lessons learned since the ORIGINAL issue. This document contains minimum requirements for fabrication and inspection of submarine and non-combatant submersible structure, including shipbuilding practices, specifications for materials, weld joint design, workmanship, welding, inspection, and record requirements. Minor structure (as defined in 3.33.3.1) is exempt from the requirements listed herein. Such structure shall be fabricated using good shipbuilding practices and may be performed using AWS, ASTM, or other commercial standards.
