About this file
This Design Change Notice from the Naval Sea Systems Command details revisions to technical drawings for a portable sail staging platform used on SSN 774 class submarines. Specifically, Note 35 and Item 11 remarks will be updated to clarify load testing and proof testing requirements for the lifting eyes, requiring a 14,000 pound load be applied for 10 minutes followed by a visual inspection for cracks, deformation or damage per specified standards before retesting any repaired components. The revisions ensure the lifting eyes can safely withstand the loads applied during platform installation and removal.
This federal contract opportunity posted by the Department of the Navy seeks proposals for an indefinite delivery/indefinite quantity multiple award contract to acquire Virginia Class submarine racetracks, payload tube platforms and ladder kits. Interested offerors should review the attached request for proposal detailing the full requirement scope. Proposals must be submitted directly without use of email by the response date specified in the RFP.
