KH-8 no. 45 (GAMBIT 83) was launched on 1975 Oct 9 by Titan 23B Agena D from Vandenberg into a new type of orbit: 125 x 356 km x 96.4 degrees. The perigee was 10 km lower than previous missions in the 1970s the apogee 50 km lower, and the inclination reverted to the 96 degrees used by the Atlas Agena flights of the 1960s. This new inclination would be used by the remainder of the GAMBIT series, and the low perigee would also become the norm, requiring almost daily reboosts with the Agena engine.
