26 February 1966: AS-201, a Saturn IB launch vehicle, carried the first complete Block 1 Apollo Command and Service Module on a 37 minute, 19.7 second unmanned suborbital test flight. Liftoff was at 11:12:01 a.m., EST, from Launch Complex 34 at the Kennedy Space Center, Cape Canaveral, Florida.
This flight was a demonstration of the combined Apollo Command Module and the Service Module. The second production Apollo capsule, CM-009, and the first production service module, SM-009, were launched by the first Saturn IB, SA-201.
The Apollo capsule reached a maximum altitude of 305.8 miles (492.1 kilometers) and landed near Ascension Island in the South Atlantic Ocean, 5,267 miles (8,477 kilometers) from Cape Canaveral. (S. 8.18°, W 11.15°) Total duration of the flight was 37 minutes, 19.7 seconds.
The Apollo spacecraft was recovered by USS Boxer (LPH- 4).
The flight was successful, though several problems occurred. These were identified and corrected on the following production vehicles.
The Apollo command module of AS-201 was Spacecraft 009. It was a Block I capsule. The Apollo was a conical space capsule designed and built by North American Aviation to carry a crew of three on space missions of two weeks or longer.
The Saturn IB consisted of an S-IB first stage and an S-IVB second stage. The S-IB was built by Chrysler Corporation Space Division at the New Orleans Michoud Assembly Facility. It was powered by eight Rocketdyne H-1 engines, burning RP-1 and liquid oxygen. Eight Redstone rocket fuel tanks containing the RP-1 fuel surrounded a Jupiter rocket tank containing the liquid oxygen. The S-IB stage is 80 feet, 2 inches (24.435 meters) long, with a diameter of 21 feet, 5 inches (6.528 meters). The empty weight of this stage was 85,000 pounds (38,555 kilograms). Fully fueled, it weighed 498,099 pounds (225,934 kilograms). Total thrust of the S-IB stage was 1,600,000 pounds (7,117,155 Newtons) and it carried sufficient propellant for 2 minutes, 35 seconds burn time. This would lift the vehicle to an altitude of 37 nautical miles (69 kilometers).
The Douglas Aircraft Company-built S-IVB second stage was assembled at Huntington Beach, California. It was powered by one Rocketdyne J-2 engine, also fueled by liquid hydrogen and liquid oxygen. The S-IVB is 60 feet, 1 inch (18.313 meters) long with a diameter of 21 feet, 8 inches (6.604 meters). The second stage had an empty weight of 28,400 pounds (12,882 kilograms) and gross weight was 261,900 pounds (118,796 kilograms). The single engine produced 232,250 pounds of thrust (1,033,100 Newtons) and and its burn time was 7 minutes, 55 seconds.
The AS-201 223 feet, 6 inches (68.123 meters). The total vehicle weight was 1,320,220 pounds (598,842 kilograms). It was capable of launching a 46,000 pound (20,865 kilogram) payload to Earth orbit.
After being recovered, the AS-201 Apollo command module was used for drop tests. It is at the Strategic Air and Space Museum, Ashland, Nebraska.
