Concur Gulfstream also has a military variants ready if that could grease the skids further (domestic supplier) https://www.gulfstream.com/en/aircraft/special-missions/ I’m surprised this idea of smaller manned HVAA platforms for C2, EA, ISR, AR, etc… has not taken hold and the AF shifting that way. Unmanned and space based eventually but large cabin sized biz jet based systems are the low risk, capabilities TODAY to get to the next stage. I might see the need for some manned large (transport category platform) multi mission platforms but for strategic patrol / monitoring missions. But it would need to do it all, active and passive collection, over very long ranges, if it made sense.
