  • Initial operational capability demonstration launch - . Nation: USA. Agency: USAF SAC. Apogee: 1,800 km (1,100 mi).

    A SAC crew conducted the first west coast launch of an Atlas operational configuration missile, 12D, from Vandenberg AFB, to a target near Wake Island, Afterward, General Thomas S. Power, CINCSAC, declared the Atlas system to be operational. This marked the attainment of operational status for the Atlas one year earlier than the six years that the von Neumann Committee had projected in its February 1954 report. The first prototype of the Mercury-Atlas capsule for NASA's Project Mercury was launched atop Atlas 10D from Cape Canaveral. First SAC operational (IOC) launch, 576th SMS, successful: impacted within one mile of target near Wake Island, a 4,480 nautical mile flight. Afterwards, General Thomas S. Power, Commander in Chief of Strategic Air Command, declared the Atlas system to be operational.
