- pfdietz 5y agoDelta-II was not a F9-class launcher. The first stage thrust (ignoring strapons, which one should because F9 doesn't use them) was less than 1/7th that of the F9. A closer match was the Saturn IB.
- bodhiandphysics 5y agoDelta ii was designed around boosters! Also when falcon 9 was developed its target payload was ten tons to Leo, similar to delta ii’s 8
- pfdietz 5y agoF9 1.0's payload to LEO was 11.5 tons, vs. (up to) 6.8 tons for Delta II. Yes, D9 was designed around boosters. This means D9 is a different kind of design than F9. I'm contending that a more F9-like design, like Saturn 1B, could have evolved into something like the F9 over time. D-II could not have.
