Sources Sought: Urgent – NCMS is Assisting the U.S. Air Force in Seeking Materials to Create Dorsal Longerons for Use on the B-1
The U.S. Air Force has an immediate need for 1 billet of materials to create Dorsal Longerons (DL) for the B-1. All suppliers that have this material available are encouraged to respond.
Problem
Materials are scarce and in high demand due to the supply chain disruption from the Covid-19 pandemic. The U.S. Air Force urgently needs 1 billet of materials to create Dorsal Longerons for the upper fuselage repair efforts for the B-1 Bomber. Without this material, work will stop in a matter of weeks leading to a potential significant schedule delay. Companies that can deliver material for this immediate B-1 need may have the opportunity to supply up to 36 additional billets of DL materials for multiple B-1 repairs into the future, starting in FY23 with 5 delivered per year.
