He can try that, but it's a shit strategy. Funding R&D doesn't just develop new technology in a vacuum. It also builds your company's R&D capacity going forward. It attracts the highest-quality engineers, allows you to recruit the most promising new grads and poach the best engineers from your un-sexy competition. This all makes developing the next advance easier, while your competition still has to catch up with your last one. BO will end up further and further behind, and the only reason it's acceptable to Bezos is because his heart was never really in it to begin with.

internally it's like 25 mill cost to build+launch. A re-used core cuts the marginal internal launch cost to a substantial fraction of that; still have to build a stage 2 every time tho

Right now ULA's booster engines are all SRBs (lol), RS-68s (FIRST STAGE HYDROLOGS :DDDDD), or ancient Soviet designed RD-180s. I'm not super surprised a modern design can beat those on TWR.

>> No.12556564

>>12556443
Entire range of design choices all through the vehicle also kerolox without subcooling is great but with copv submerged with deep cryo lox common bulkheads and semi pressure stabilized lox tanks you reach stupidly high efficiency levels another one is that most merlins have low thrust structure mass due to being on edges of the tank.
