ABL claims their RS1 can run on RP-1 *or* Jet-A. One assumes that all their performance numbers are based on RP-1, with the reduction from using Jet-A being something you discuss with them if you're talking about launching from a site without access to RP-1.

Both can be trucked in of course, but Jet-A would be cheaper and easier to move.

RP-1 is a specially refined Kerosene, which is not as commonly available. LOX or Jet-A are both commodities you can acquire in volume with a few hours notice, whereas RP-1 is not.

LOX cooling for American and European engine uses is progressing in projects but Russian the only ones in productions

Dan Piemont, ABL’s president and CFO, shared his view on the company’s new status.“We don’t see our valuation as an achievement so much as a serious responsibility to deliver value,” Piemont told CNBC. “We’ve never optimized for valuation and we’ve kept most of our achievements private. We know we still have a lot to prove. We’re out to build an enduring company with the best people, customers, and investors in the world.”
