Artillery shells are entirely capable of being launched into orbit re
John Bull. So? Calculate the acceleration of a 125-grain hollow
point semijacketed round going from zero to 1250 ft/sec in six inches
of .357 magum barrel. Now, pick your field artillery and don't ride
in the shell - or do.
Piggyback modes of orbital insertion, air breathing mothership then
rocket, have been disappointing at scale. Look at the payload of the
SR-71 Blackbird. The huge thing hardly carries more than its tankage.
