Associated space launch
The Transit-O series of satellites that closely followed the design of Transit 5C-1 were also called “Oscars” (Oscar is the phonetic alphabet for “O”, i. e., operational). They were also called NNS (Navy Navigation Satellite) or shortened NavSat.
SCOUT A R/B was lifted into orbit during the mission ‘Scout A | Transit-O 19’, on board a Scout A space rocket.
The launch took place on Aug. 27, 1970, 1:23 p.m. from Space Launch Complex 5.
