The complex was built for the Atlas ballistic missile program. Launch sites 11 to 14 were accepted between August 1957 and mid-April 1958. After its final Atlas missile launch, Complex 14 was converted into an Atlas /Agena launch complex, and later turned over to NASA. Complex 14 supported 32 Atlas and Atlas/Agena missions, including four manned Mercury missions and seven unmanned Gemini target vehicle launches. Complexes 11, 12 and 14 were deactivated in 1967. Complex 14 and the gantry on Complex 13 were declared national historic landmarks in April 1984.

• 1960 July 29 14:13 - Mercury MA-1 Launch Vehicle: Atlas D. Structural failure of Atlas.. Atlas D 50D Apogee: 13 km (8 mi). Mercury-Atlas 1 (MA-1) was launched from the Atlantic Missile Range in a test of spacecraft structural integrity under maximum heating conditions. After 58.5 seconds of flight, MA-1 exploded and the spacecraft was destroyed upon impact off-shore. None of the primary capsule test objectives were met. The mission objectives were to check the integrity of the spacecraft structure and afterbody shingles for a reentry associated with a critical abort and to evaluate the open-loop performance of the Atlas abort-sensing instrumentation system. The spacecraft contained no escape system and no test subject. Standard posigrade rockets were used to separate the spacecraft from the Atlas, but the retrorockets were dummies. The flight was terminated because of a launch vehicle and adapter structural failure. The spacecraft was destroyed upon impact with the water because the recovery system was not designed to actuate under the imposed flight conditions. Later most of the spacecraft, the booster engines, and the liquid oxygen vent valve were recovered from the ocean floor. Since none of the primary flight objectives was achieved, Mercury-Atlas 2 (MA-2) was planned to fulfill the mission.

• 1960 September 19 18:31 - Research and development launch Launch Vehicle: Atlas D. Atlas D 79D Apogee: 1,800 km (1,100 mi). Atlas ICBM fired 9030 statute miles, from Cape Canaveral to the Indian Ocean off the Cape of Good Hope in 50 minutes, the second record distance flight.

• 1960 October 22 05:13 - Research and development launch Launch Vehicle: Atlas D. Atlas D 55D Apogee: 1,800 km (1,100 mi).

• 1961 February 21 14:12 - Mercury MA-2 Launch Vehicle: Atlas D. Atlas D 67D Apogee: 182 km (113 mi). Range: 2,309 km (1,434 mi). Mercury-Atlas 2 (MA-2) was launched from Cape Canaveral in a test to check maximum heating and its effects during the worst reentry design conditions. The flight closely matched the desired trajectory and attained a maximum altitude of 114.04 statute miles and a range of 1,431.6 statute miles. Inspection of the spacecraft aboard the recovery ship some 55 minutes after launch (actual flight time was 17.56 minutes) indicated that test objectives were met, since the structure and heat protection elements appeared to be in excellent condition. The flight control team obtained satisfactory data; and the complete launch computing and display system, operating for the first time in a flight, performed satisfactorily.

• 1961 April 25 16:15 - Mercury MA-3 Launch Vehicle: Atlas D. Destroyed by range safety.. Atlas D 100D Mercury-Atlas 3 (MA-3) was launched from Cape Canaveral in an attempt to orbit the spacecraft with a 'mechanical astronaut' aboard. After lift-off, the launch vehicle failed to roll to a 70 degree heading and to pitch over into the proper trajectory. The abort-sensing system activated the escape rockets prior to the launch vehicle's destruction by the range safety officer after approximately 40 seconds of flight that had attained an altitude of 16,400 feet. The spacecraft then coasted up to 24,000 feet, deployed its parachutes, and landed in the Atlantic Ocean 2,000 yards north of the launch pad. The spacecraft was recovered and was found to have incurred only superficial damage; it was then shipped to McDonnell for refitting.

• 1961 September 13 14:04 - Mercury MA-4 Launch Vehicle: Atlas D. Atlas D 88D Apogee: 248 km (154 mi). Mercury-Atlas 4 (MA-4) was launched from Cape Canaveral with special vibration and noise instrumentation and a mechanical crewman simulator aboard in addition to the normal spacecraft equipment. This was the first Mercury spacecraft to attain an earth orbit. The orbital apogee was 123 nautical miles and the perigee was 86 nautical miles. After one orbit, the spacecraft's orbital timing device triggered the retrograde rockets, and the spacecraft splashed in the Atlantic Ocean 161 miles east of Bermuda. Recovery was made by the USS Decatur. During the flight, only three slight deviations were noted - a small leak in the oxygen system; loss of voice contact over Australia; and the failure of an inverter in the environmental control system. Overall, the flight was highly successful: the Atlas booster performed well and demonstrated that it was ready for the manned flight, the spacecraft systems operated well, and the Mercury global tracking network and telemetry operated in an excellent manner and was ready to support manned orbital flight.

• 1961 November 29 15:07 - Mercury MA-5 Launch Vehicle: Atlas D. Atlas D 93D Apogee: 237 km (147 mi). Mercury-Atlas 5 (MA-5), the second and final orbital qualification of the spacecraft prior to manned flight was launched from Cape Canaveral with Enos, a 37.5 pound chimpanzee, aboard. Scheduled for three orbits, the spacecraft was returned to earth after two orbits due to the failure of a roll reaction jet and to the overheating of an inverter in the electrical system. Both of these difficulties could have been corrected had an astronaut been aboard. The spacecraft was recovered 255 miles southeast of Bermuda by the USS Stormes. During the flight, the chimpanzee performed psychomotor duties and upon recovery was found to be in excellent physical condition. The flight was termed highly successful and the Mercury spacecraft well qualified to support manned orbital flight.

• 1962 February 20 14:47 - Mercury MA-6 Launch Vehicle: Atlas D. Atlas D 109D Apogee: 265 km (164 mi). First US manned orbital mission. John Glenn finally puts America in orbit. False landing bag deploy light led to reentry being started with retropack left in place on heat shield. It turned out that indicator light was false and a spectacular reentry ensued, with glowing chunks of the retropack whizzing by the window. After four hours and 43 minutes the spacecraft reentered the atmosphere and landed at 2:43 pm EST in the planned recovery area NE of the Island of Puerto Rico. All flight objectives were achieved. Glenn was reported to be in excellent condition. Beause of failure of one of the automatic systems, the astronaut took over manual control of the spacecraft during part of the flight. With this flight, the basic objectives of Project Mercury had been achieved.

• 1962 May 24 12:45 - Mercury MA-7 Launch Vehicle: Atlas D. Atlas D 107D Apogee: 260 km (160 mi). Scott Carpenter in Aurora 7 is enthralled by his environment but uses too much orientation fuel. Yaw error and late retrofire caused the landing impact point to be over 300 km beyond the intended area and beyond radio range of the recovery forces. Landing occurred 4 hours and 56 minutes after liftoff. Astronaut Carpenter was later picked up safely by a helicopter after a long wait in the ocean and fears for his safety. NASA was not impressed and Carpenter left the agency soon thereafter to become an aquanaut.

• 1962 October 3 12:15 - Mercury MA-8 Launch Vehicle: Atlas D. Atlas D 113D Apogee: 285 km (177 mi). The Sigma 7 spacecraft with Astronaut Walter M. Schirra, Jr., as pilot was launched into orbit by a Mercury-Atlas vehicle from Atlantic Missile Range. In the most successful American manned space flight to date, Schirra traveled nearly six orbits, returning to earth at a predetermined point in the Pacific Ocean 9 hours, 13 minutes after liftoff. Within 40 minutes after landing, he and his spacecraft were safely aboard the aircraft carrier U.S.S. Kearsarge. Schirra attempted and achieved a nearly perfect mission by sticking rigorously to mission plan.

• 1963 May 15 13:04 - Mercury MA-9 Launch Vehicle: Atlas D. Atlas D 130D Apogee: 265 km (164 mi). Final Mercury mission, Faith 7, was piloted by Astronaut L. Gordon Cooper, Jr.

• 1965 October 25 15:00 - Gemini 6 Agena Target Launch Vehicle: SLV-3 Atlas / Agena D. Exploded 6 minutes after takeoff. Failure.. SLV-3 Agena D 5301 / Agena D 5002 The Agena target vehicle failed to reach orbit. Gemini 6, awaiting launch, was cancelled. In the ashes of this setback, the idea of launching Gemini 6 to rendezvous with Gemini 7 was born.

• 1966 March 16 15:00 - Gemini 8 Agena Target Launch Vehicle: SLV-3 Atlas / Agena D. SLV-3 Agena D 5302 / Agena D 5003 Apogee: 299 km (185 mi). Target vehicle for Gemini 8.

• 1966 June 1 15:00 - Gemini 9 ATDA Launch Vehicle: SLV-3 Atlas. Atlas SLV-3 5304 Apogee: 296 km (183 mi). The ATDA achieved a near-circular orbit (apogee 161.5, perigee 158.5 nautical miles). One hour and 40 minutes later, the scheduled launch of Gemini IX-A was postponed by a ground equipment failure which prevented the transfer of updating information from Cape Kennedy mission control center to the spacecraft computer. The mission was recycled for launch on June 3, following a prepared 48-hour recycle plan. Anomalous telemetry indicated some sort of problem with the target, but it was not until Gemini IX rendezvoused with it in orbit that it was seen that fairing separation had failed.

• 1966 July 18 20:39 - Gemini 10 Agena Target Launch Vehicle: SLV-3 Atlas / Agena D. SLV-3 Agena D 5305 / Agena D 5005 Apogee: 296 km (183 mi). Space craft engaged in investigation of spaceflight techniques and technology (US Cat A).
