Crossing the ocean with 500 tons of cargo at 500km/h using liquid hydrogen fuel on a giant sea-skimming, lifting-body plane: this is what the HCA-LB aims for.
The UHCA-LB targets 1200 tons across 11,000 km.

Concept art done for @GRRMspeaking's 'Nightflyers'.
It's a high quality example of the 'cargo cult' approach to spaceship design. The pieces look right but don't go together or make sense overall.

Before the nuclear pulse propulsion Orion, there was Helios.
20 GJ explosions inside a 10m wide chamber heated hydrogen gas to 6000K.
The walls had to withstand 3-5 kilobar pulses and 4000K surface temperature...

'Giraffe tanks' were a Cold War solution to maximizing the range of early ATGMs while hiding behind inclines or over forests.
They were no longer needed once smarter munitions became available.

The Shoemaker-Levy comet struck Jupiter in 1994 with a kinetic energy equivalent of 6,000,000 megatons of TNT.
Any yet, it might not even have produced an echo on Jupiter, seeing as how thousands of kilometres of gases separate the surface from the denser core layers...

Could galactic cosmic rays interact with RP-1 in an orbital propellant depot to create bubbles of lighter hydrocarbons, which could go on to vapour lock feed lines?

I have been unable to find much information on what @AtomosSpace is offering.
They mention nuclear technology and higher specific power on-orbit propulsion...
