Gambit-3 3
1966-113A
KH-8 flight 4303 was launched on 1966 Dec 14 by Titan 3B Agena D from Vandenberg. The spacecraft entered a 138 x 368 km x 110 degree orbit, parameters which would remain typical of KH-8 missions for a decade. The orbit was lowered during the 8-day primary flight. The Agena was deorbited after 10 days.

Denpa
1972-064A
ISAS's Radio Exploration Satellite (REXS) was launched in 1972 and renamed Denpa (Radio wave). It studied the ionosphere and lower magnetosphere but failed after 3 days. Switch on of the EBA caused electrical discharges which toasted the spacecraft encoder. The radio beacon continued to operate until May 1973. REXS was a 70 kg, octagonal cylinder 0.68 h 0.71 dia with three 2m antennas.
M-4S-2 Mass of stage 4 plus payload is 525 f 145 em. Prop mas 380 kg. Payload mass 75 kg implying M-40 is 450f 70 em. Isp 276.0s?
