S-IC - American missile stage . Used on the Saturn V launch vehicle as a first stage, manufactured by Boeing Corporation. It was equipped with five F-1 oxygen-kerosene engines, one of which was fixedly mounted in the center, and four were mounted on the outer ring and could deviate to control the thrust vector.

Content
Design
Five oxygen-kerosene F-1 engines were installed on the stage, the total thrust of which was more than 34,000 kN . The first stage worked for about 160 seconds, accelerated the subsequent stages and the payload to a speed of about 2.7 km / s (in the inertial reference system; 2.3 km / s relative to the ground), and separated at an altitude of about 70 kilometers [1] . After separation, the step rose to a height of about 100 km, then fell into the ocean. One of the five engines was fixed in the center of the stage, four others were symmetrically located at the edges under the fairings and could be rotated to control the thrust vector. In flight, the central engine turned off earlier to reduce overload. The diameter of the first step is 10 meters (without fairings and aerodynamic stabilizers), a height of 42 meters.
