<h2 id="history">History</h2> <p>In 1959, NASA's <a href="/facts/Silverstein_Committee/0VJSMkPB">Silverstein Committee</a> issued recommendations to develop the <a href="/facts/Saturn_(rocket_family)/IzWRe4GJ">Saturn class</a> launch vehicles, growing from the <a href="/facts/Saturn_I/5Tp3eQ72">C-1</a>. When the <a href="/facts/Apollo_program/IC1Ek1Ao">Apollo program</a> was started in 1961 with the goal of landing men on the Moon, NASA chose the Saturn I for Earth orbital test missions. However, the Saturn I's payload limit of 20,000 pounds (9,100 kg) to 162 km would allow testing of only the <a href="/facts/Apollo_command_module/rfoTgzFx">command module</a> with a smaller propulsion module attached, as the <a href="/facts/Command_and_service_module/rfoTgzFx">command and service module</a> would have a dry weight of at least 26,300 pounds (11,900 kg), in addition to service propulsion and reaction control fuel. In July 1962, NASA announced selection of the <a href="/facts/Saturn_V/WhpUEFJM">C-5</a> for the lunar landing mission, and decided to develop another launch vehicle by upgrading the Saturn I, replacing its <a href="/facts/S-IV/SnY2pnqu">S-IV</a> second stage with the <a href="/facts/S-IVB/CaTRQF2a">S-IVB</a>, which would also be modified for use as the Saturn V third stage. The <a href="/facts/S-I/lnTsGyFM">S-I</a> first stage would also be upgraded to the S-IB by improving the thrust of its engines and removing some weight. The new Saturn IB, with a payload capability of at least 35,000 pounds (16,000 kg),<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a> would replace the Saturn I for Earth orbit testing, allowing the command and service module to be flown with a partial fuel load. It would also allow launching the 32,000-pound (15,000 kg) <a href="/facts/Lunar_excursion_module/XtvQS5K5">lunar excursion module</a> separately for uncrewed and crewed Earth orbital testing, before the Saturn V was ready to be flown. It would also give early development to the third stage.<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a> </p><p>On May 12, 1966, NASA announced the vehicle would be called the "uprated Saturn I", at the same time the "lunar excursion module" was renamed the <a href="/facts/Lunar_module/YaMcbbKz">lunar module</a>. However, the "uprated Saturn I" terminology was reverted to Saturn IB on December 2, 1967.<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a> </p><p>By the time it was developed, the Saturn IB payload capability had increased to 41,000 pounds (19,000 kg).<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a> By 1973, when it was used to launch three <a href="/facts/Skylab/h7v9LWKE">Skylab</a> missions, the first-stage engine had been upgraded further, raising the payload capability to 46,000 pounds (21,000 kg). </p> <h2 id="specifications">Specifications</h2> <h3>Launch vehicle</h3> <table><tbody><tr><th>Parameter<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a></th><th>S-IB (1st stage)</th><th>S-IVB (2nd stage)</th><th>Instrument unit</th></tr><tr><th>Height</th><td>24.44 m (80.17 ft)</td><td>17.81 m (58.42 ft)</td><td>0.91 m (3 ft)</td></tr><tr><th>Diameter</th><td>6.53 m (21.42 ft)</td><td>6.61 m (21.67 ft)</td><td>6.61 m (21.67 ft)</td></tr><tr><th>Structural mass</th><td>42,000 kg (92,500 lb)</td><td>10,600 kg (23,400 lb)</td><td>2,000 kg (4,400 lb)</td></tr><tr><th>Propellant</th><td><a href="/facts/Liquid_oxygen/qnI0KDTb">LOX</a> / <a href="/facts/RP-1/wDI7vNdu">RP-1</a></td><td><a href="/facts/Liquid_oxygen/qnI0KDTb">LOX</a> / <a href="/facts/LH2/Vpk3Gb8P">LH2</a></td><td>—</td></tr><tr><th>Propellant mass</th><td>399,400 kg (880,500 lb)</td><td>103,600 kg (228,500 lb)</td><td>—</td></tr><tr><th>Engines</th><td>8 × <a href="/facts/Rocketdyne_H-1/w0RDNfF6">H-1</a></td><td>1 × <a href="/facts/Rocketdyne_J-2/oNtBBUD7">J-2</a></td><td>—</td></tr><tr><th>Thrust</th><td>7,100 kN (1,600,000 lbf) sea level</td><td>890 kN (200,000 lbf) vacuum</td><td>—</td></tr><tr><th>Burn duration</th><td>150 seconds</td><td>480 seconds</td><td>—</td></tr><tr><th>Specific impulse</th><td>272 s (2.67 km/s) sea level</td><td>420 s (4.1 km/s) vacuum</td><td>—</td></tr><tr><th>Contractor</th><td><a href="/facts/Chrysler/kMHhMgYx">Chrysler</a></td><td><a href="/facts/Douglas_Aircraft_Company/vkkFDEhB">Douglas</a></td><td><a href="/facts/IBM/QszA7nwd">IBM</a></td></tr></tbody></table> <h3>Payload configurations</h3> <table><tbody><tr><th>Parameter</th><th><a href="/facts/Apollo_command_and_service_module/rfoTgzFx">Command and service module</a></th><th><a href="/facts/Apollo_5/mXnS5NIQ">Apollo 5</a></th><th><a href="/facts/AS-203/fs7QK0Et">AS-203</a></th></tr><tr><th><a href="/facts/Apollo_Spacecraft/gv7k516G">Launch Escape System</a> mass</th><td>4,200 kg (9,200 lb)</td><td>—</td><td>—</td></tr><tr><th><a href="/facts/Apollo_command_and_service_module/rfoTgzFx">Apollo command and service module</a> mass</th><td>16,500 to 20,900 kg (36,400 to 46,000 lb)</td><td>—</td><td>—</td></tr><tr><th><a href="/facts/Apollo_Lunar_Module/XtvQS5K5">Apollo Lunar Module</a> mass</th><td>—</td><td>14,360 kg (31,650 lb)</td><td>—</td></tr><tr><th><a href="/facts/Apollo_Spacecraft/gv7k516G">Spacecraft–LM adapter</a> mass</th><td>1,840 kg (4,050 lb)</td><td>1,840 kg (4,050 lb)</td><td>—</td></tr><tr><th><a href="/facts/Nose_cone/hnQJWnrr">Nose cone</a> height</th><td>—</td><td>2.5 m (8.3 ft)</td><td>8.4 m (27.7 ft)</td></tr><tr><th>Payload height</th><td>24.9 m (81.8 ft)</td><td>11.1 m (36.3 ft)</td><td>—</td></tr><tr><th>Total space vehicle height</th><td>68.1 m (223.4 ft)</td><td>54.2 m (177.9 ft)</td><td>51.6 m (169.4 ft)</td></tr></tbody></table> <h3>S-IB first stage</h3> <p class="note">Main article: <a href="/facts/S-IB/8entmwkm">S-IB</a></p> <p>The S-IB stage was built by the <a href="/facts/Chrysler/kMHhMgYx">Chrysler</a> corporation at the <a href="/facts/Michoud_Assembly_Facility/7KluP8yU">Michoud Assembly Facility</a>, <a href="/facts/New_Orleans%2c_Louisiana/IgCn61KH">New Orleans</a>.<a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a> It was powered by eight <a href="/facts/Rocketdyne_H-1/w0RDNfF6">Rocketdyne H-1</a> rocket engines burning <a href="/facts/RP-1/wDI7vNdu">RP-1</a> fuel with <a href="/facts/Liquid_oxygen/qnI0KDTb">liquid oxygen</a> (LOX).

Located at the top of the S-IVB stage, it consisted of a Launch Vehicle Digital Computer (LVDC), an inertial platform, accelerometers, a tracking, telemetry and command system and associated environmental controls. It controlled the entire rocket from just before liftoff until battery depletion. Like other rocket guidance systems, it maintained its <a href="/facts/Orbital_state_vectors/9PlwJYYP">state vector</a> (position and velocity estimates) by integrating accelerometer measurements, sent firing and steering commands to the main engines and auxiliary thrusters, and fired the appropriate ordnance and solid rocket motors during staging and payload separation events. </p><p>As with other rockets, a completely independent and redundant <a href="/facts/Range_safety/gRaLMqaj">range safety</a> system could be invoked by ground radio command to terminate thrust and to destroy the vehicle should it malfunction and threaten people or property on the ground. In the Saturn IB and V, the range safety system was permanently disabled by ground command after safely reaching orbit. This was done to ensure that the S-IVB stage would not inadvertently rupture and create a cloud of debris in orbit that could endanger the crew of the Apollo CSM. </p> <h2 id="launch-sequence-events">Launch sequence events</h2> <table><tbody><tr><th>Launch event<a class="footnote-ref" id="fnref:10" href="#fn:10"><sup>10</sup></a></th><th scope="col">Time (s)</th><th scope="col">Altitude (km)</th><th scope="col">Speed (m/s)</th></tr><tr><td>Guidance ref release</td><td>-5.0</td><td>0.09</td><td>0</td></tr><tr><td>First motion</td><td>0.0</td><td>0.09</td><td>0</td></tr><tr><td>Mach 1</td><td>58.9</td><td>7.4</td><td>183</td></tr><tr><td>Max dynamic pressure</td><td>73.6</td><td>12.4</td><td>328</td></tr><tr><td>Freeze tilt</td><td>130.5</td><td>48.2</td><td>1587</td></tr><tr><td>Inboard engine cutoff</td><td>137.6</td><td>54.8</td><td>1845</td></tr><tr><td>Outboard engine cutoff</td><td>140.6</td><td>57.6</td><td>1903</td></tr><tr><td>S-IB / S-IVB separation</td><td>142.0</td><td>59.0</td><td>1905</td></tr><tr><td>S-IVB ignition</td><td>143.4</td><td>59.9</td><td>1900</td></tr><tr><td>Ullage case jettison</td><td>154.0</td><td>69.7</td><td>1914</td></tr><tr><td>Launch escape tower jettison</td><td>165.6</td><td>79.5</td><td>1960</td></tr><tr><td>Iterative guidance mode initiation</td><td>171.0</td><td>83.7</td><td>1984</td></tr><tr><td>Engine mixture ratio shift</td><td>469.5</td><td>164.8</td><td>5064</td></tr><tr><td>Guidance C/O signal</td><td>581.9</td><td>158.4</td><td>7419</td></tr><tr><td>Orbit insertion</td><td>591.9</td><td>158.5</td><td>7426</td></tr></tbody></table> <p>Acceleration of the Saturn IB increased from 1.24 G at liftoff to a maximum of 4.35 G at the end of the S-IB stage burn, and increased again from 0 G to 2.85 G from stage separation to the end of the S-IVB burn.<a class="footnote-ref" id="fnref:11" href="#fn:11"><sup>11</sup></a> </p><p>AS-206, 207, and 208 inserted the <a href="/facts/Apollo_command_and_service_module/rfoTgzFx">Command and Service Module</a> in a 150-by-222-kilometer (81-by-120-nautical-mile) <a href="/facts/Elliptic_orbit/SfuXuATN">elliptical orbit</a> which was co-planar with the <a href="/facts/Skylab/h7v9LWKE">Skylab</a> one.
