    The 6555th Aerospace Test Wing launched the first Titan IIIA space booster (Vehicle #2) from the Eastern Test Range. Essentially the liquid-propellant core section of the Titan IIIC, the Titan IIIA performed satisfactorily except for a transtage (Stage 3) malfunction. After the first two stages had performed flawlessly, a premature shutdown of the transtage engine resulted from the failure of an onboard helium pressure valve and prevented the 3,750-pound dummy test payload from being injected into orbit.

Perigee: 166 km (103 mi). Inclination: 32.1000 deg. Period: 88.00 min. The second Titan 1IIA (Vehicle #1) military space booster was launched from Cape Canaveral and achieved a completely successful test flight. Launch vehicle test.

  • LES 1 - . Mass: 31 kg (68 lb). Nation: USA. Agency: USAF. Class: Technology. Type: Communications technology satellite. Spacecraft: LES. USAF Sat Cat: 1002 . COSPAR: 1965-008C. Apogee: 2,809 km (1,745 mi). Perigee: 2,783 km (1,729 mi). Inclination: 32.1000 deg. Period: 145.80 min.

    Titan IIIA, Vehicle #3, was launched from Cape Canaveral. In a maneuverability test involving three separate orbits, the Transtage and two satellites were successfully placed into their programmed orbits. The primary objective of the mission was the triple ignition of the Transtage engine that was required for the three separate orbits. When it placed the Lincoln Experimental Satellite (LES-1) into orbit, the vehicle became the first Titan III to inject an operational payload into orbit.

    The fourth Titan IIIA flight test missile (Vehicle #6) was launched from Complex 20 at Cape Canaveral in a maneuverability test for the Transtage. The primary aim was for the Transtage engine to accomplish four separate ignitions, something never before attempted. In the process of successfully completing its four programmed ignitions and burns, the Transtage placed two satellites into orbit - a Lincoln Experimental Satellite (LES-2) and a hollow aluminum radar calibration sphere (LCS-1). By completing its assigned tasks, the Transtage extended the capabilities of the Titan IIIA beyond it's specific requirements. Because of this highly productive mission, the planned fifth Titan IIIA (Vehicle 7/4) launch was cancelled and the booster was converted to a Titan IIIC configuration. Experimental commsat.
