The FVL program that covers the V-280 and SB-1 started in 2013 and was originally scheduled to end in September 2019. The V-280 basically met all of the program milestones. The SB-1 apparently still has not progressed much beyond hover. The latest Marine RFI has scheduled a Nov - Jan response window with the requirements being derived from the original program’s results. It is not the fault of Bell that Sikorsky has nothing from its SB-1 effort.
As the program was originally scheduled to end in Sept and the requirements for the production version have been defined it seemed logical that the 280 would rap up with a big demo to program stake holders (like flown today).
