Transit 3B navigation satellite for the U.S. Navy and NRL LOFTI-1 ionospheric experiment, launched together on a Thor Ablestar from Cape Canaveral. Partial failure: the payloads reached a more eccentric orbit than planned and never separated from the Ablestar upper stage, though some data were returned.
