Well, this is true of smaller warheads, but subs aren't necessarily able to take a fix from a satellite system at all, nor would they expect to have time to do so before launch. So far as I know -- which isn't very far -- no ballistic system relies on GPS for navigational inputs. -- Graydon -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
