What happens to Boeing Vertol is a good question, though I imagine they can make consistent money off supporting the AH-64 and CH-47 fleets for another generation and perhaps they have something cooking for whatever the heavy end of FVL becomes. I think your point is that not winning SB>1 hurts their ability to develop new products, but I’d argue that damage was done generations ago. The last clean sheet aircraft they developed all on their own was YUH-61 and even that had licensed MBB tech in the rotor system. BV is an agglomeration of other people’s old product support lines, not a full fat VTOL OEM.
