  RS-11 was launched at 0051 hours EST from AMR after a three-hour hold. The flight was unsuccessful. The LOX container pressure and the combustion chamber decreased 50 seconds after lift-off. The temperature of Fin Number 1 went out of measuring range 72 seconds after lift-off. The servo battery current dropped to zero and the stabilised platform lost its reference. The range safety officer gave the emergency cut-off signal at 79 seconds. Impact occurred approximately 21,000 yards from the launch pad. The RS-11 was the first flight with the complete guidance system. Missed aimpoint by 118,800 m.

• Nation: USA. Agency: US Army. Apogee: 90 km (55 mi).

  RS-12 was launched from AMR at 1946 hours EST. The flight was successful.

  The first Jupiter A launching, by ABMA at Cape Canaveral. RS-18 was launched at 1936 hours EST from AMR. The flight was successful. The scheduled launching date of this missile was 13 March. Three holds were called because of LOX difficulties, telemetry difficulties, and replacement of a gate valve. The actual range was 133.58 nm; 10.3 nm under; and 5.66 nm right of the intended impact point. Separation occurred before the missile gained its correct velocity. Improper assumption of propellant flow for the trajectory calculation was primarily responsible for the incorrect cut-off. The primary test objectives were to test the complete guidance and control system to establish the performance qualities of the complete missile system. Missed aimpoint by 19,100 m.

  RS-19 was launched at 2322 hours EST from AMR. The flight was successful. The actual range was 169.4 nm; 13 nm over the intended impact point. Cut-off wee given by the alcohol depletion switch that sensed alcohol injector pressure drop-off. Takeoff occurred 0.156 seconds after firing. The missile followed the correct trajectory with no obvious deviation. Missile cut-off occurred later than predicted and caused the missile to impact approximately 6.5 nm long, During descent the warhead turned left, causing impact to be several miles to the left of the aiming azimuth line. The primary test objectives were to test the angle-of-attack meter hardware (Jupiter control). Missed aimpoint by 25,100 m.

• Jupiter A - . Nation: USA. Agency: US Army. Apogee: 0 km (0 mi).

  RS-25 was launched at 2104 hours EST from AMR. The flight was not successful. The behaviour of the missile appeared normal for the first 13 seconds, an early roll disturbance having been smoothly eliminated. Starting at 13 seconds after range zero, the gyro yaw signal indicated increasing yaw for a few seconds and the tracking devices at the same time showed increased displacement to the left of the standard trajectory. The malfunction apparently occurred between the yaw gyro potentiometer output and the outputs of the yaw amplifier of the mixing computer. The primary test objective was to test power plant performance. Missed aimpoint by 264,900 m.

• Jupiter A/Sandia PL - . Nation: USA. Agency: US Army. Apogee: 90 km (55 mi).

  RS-28 was launched at 2105 EST from AMR. The flight was successful. Actual range was 152.4 nm; 9.51 nm over; and 1.5 kilometres left of the intended impact point. The missile carried the LEV-3 rather than the ST-80 guidance system and used fuel depletion cut-off. The primary test objective was to test the Sandia payload. Missed aimpoint by 19,500 m.

• Jupiter A - . Nation: USA. Agency: US Army. Apogee: 90 km (55 mi).

  Launched at 0823 hours EST from AMR. The flight was successful. Actual range was 138.969 nm; .137 nm over and 122 meters left of the intended impact point, a radial miss distance of 260 meters.

• Jupiter A - . Nation: USA. Agency: US Army. Apogee: 90 km (55 mi).

  The flight was successful, Actual range was 401.6 nm; 84.9 nm over the intended impact point. The missile used Hydyne fuel.

• Jupiter A - . Nation: USA. Agency: US Army. Apogee: 90 km (55 mi).

  Launched at 2037 hours EST from AMR. The flight was successful. Actual range was 61.6 nm; 400 meters left; and 0.21 nm over the intended impact point. The primary objective was to test the accuracy of the guidance system when the missile is fired in a short range trajectory at an extreme attitude to range ratio. The missile closely followed the predicted trajectory for a successful flight which terminated 70 meters beyond and 360 meters to the Left of the expected impact point at 61.553 nm range. The short range trajectory was programmed with an extreme altitude-to-range ratio so the guidance system would be subjected to the most difficult short range expected in future tactical application. Missed aimpoint by 400 m.

Actual range was 138.178 nm; 2.2 nm under; and 1250 meters left of the intended impact point. The missile functioned properly until 182 seconds when an unexplainable pitch deviation caused a slow tilting of the missile top section. The cut-off function at 120 seconds and the separation function at 135 seconds, after flight zero time, were both satisfactory. Missed aimpoint by 4,183 m.
