>>13583996aerospike would be a completely different engine, they're setting up serial production facility for Raptor 2 right now and it's conventional bell nozzle
you think it's just the same powerhead with a different nozzle but no, it's all very integrated and the regenerative cooling loops would pick up a wildly different amount of heat between the two bell types, which changes the entire balance of the powerhead so you need to build and design an entirely new engine basically
also, aerospike wouldn't be able to get to 380 seconds of ISP the way that Raptor Vacuum can
