Re: Wardsback

Exactly what TheOtherMatt said. SpaceX went with 9 engines to have less need for deep throttling ability, which they found was detrimental on the performance and reliability of the engine. Blue Origin is probably going for the 7:1 ratio mainly for the specs needed for the ULA launchers. Either they'll go with 7 engines on their lower stage, they found a smart way to achieve deep throttling ability or they will design a different spec of the same base design to achieve the thrust levels they need for New Glenn.
