Both the US & Russia have claimed Mach 20 with the HTV-2 (DARPA’s Falcon Project) & Avangard respectively. China’s DF-ZF HGV reportedly reaches Mach 5–10.
If this golden dome goes ahead, I suspect/guess the ensuing counter-developments will mean true Mach 20 will be achievable within a ten year time frame for all three countries.
I don’t like or support Hezbollah, but the added irony here is that Northern Ireland (where Mo Chara is from) is festooned with British-supporting terrorist flags from groups like the UDF & UDA; pro-British terrorist groups active during The Troubles.
