The following is from the Acquisitions Directorate (CG-9). Note this refers only to the river buoy tender (WLR/WLI). Earlier, CG-9 indicated that the Inland Construction Tender (WLIC) is expected to share a common afterbody with the buoy tender, so I presume there will be many similarities.
The Coast Guard released top-level requirements for the inland buoy tender waterways commerce cutter (WCC) variant in a special notice Nov. 6.
The WCC program plans to exhibit and present updates at the International WorkBoat Show in New Orleans Dec. 4-6, 2019. The program will have a booth (No. 347) and provide information about its mission needs, status, and desired fielding schedule during a presentation on Wednesday, Dec. 4 from 11 a.m. to 12 p.m. CST. A team of program members will be available to meet one-on-one on Dec. 4 with any shipbuilder that has built a ship that satisfies the inland buoy tender requirements or that could meet the requirements with minor modifications to the ship. The deadline to request a meeting regarding prospective inland buoy tenders is Nov. 18, 2019.
