Blackstar is here and now.
Or at least Aviation Week says so. The actual evidence offered is slim.
And note that the system is allegedly being retired, which might be taken
to indicate that it didn't work as well as people hoped.
Fuel is not liquid H2 but a boron hydride.
"Boron-based" doesn't necessarily mean a boron hydride. There are other
possibilities, like boron particles in a hydrocarbon fuel. (That exact
option was investigated a number of years ago as a way of getting maximum
energy density in a fuel, which seems to fit this application.)
Launch weight is probable around the 500-100Kg mark. Will the prize be
awarded if it does not at least match Blackstar?
Why is a rumored, almost certainly extremely expensive, and possibly
poorly working, military system relevant?
