No. [35], A single Titan II complex belonging to the former strategic missile wing at Davis–Monthan Air Force Base escaped destruction after decommissioning and is open to the public as the Titan Missile Museum at Sahuarita, Arizona. For orbital launches, there were stro… [2] Stage I contained three gyros and the Autopilot. Titan III C - Titan II core with two solid rocket strap-ons. One person died in the accident. On 19 September 1980, a major explosion occurred after a socket from a large socket wrench rolled off a platform and punctured the missile's lower-stage fuel tank, causing a fuel leak. However, unlike its predecessor, the Titan II didn’t need to be raised to ground level on an elevator prior to launch, and was the first ICBM capable of launching from inside a silo.6 Additionally, the silo complexes were located 13 to 19 kilometers apart.7 These factors increased the missile’s survivability in the event of a first-strike scenario and allowed it to launch within 60 seconds of receiving a launch order. FUZZ, DISTORTION, OVERDRIVE… The Titan II is a unique discrete circuit using silicon transistors. The Titan II was an American Human-rated expendable rocket that was in service with NASA and the United States Air Force in the mid-20th century. All were launched from the then-Cape Kennedy Air Force Station in 1964–66. [5], The Titan rocket family was established in October 1955, when the Air Force awarded the Glenn L. Martin Company a contract to build an intercontinental ballistic missile (ICBM). It weighed 149,700 kilograms when fully fueled and had a range of 15,000 km. Also, because Aerozine doesn’t require cooling, the missile could remain fueled, cutting down on launch preparation time.3, Test flights for the missile were conducted from March 1962 until April 1964. Spirers, David N., “On Alert An Operational History of the United States Air Force Intercontinental Ballistic Missile (ICBM) Program, 1945-2011,” Air Force Space Command, United States Air Force, Colorado Springs, Colorado, 2012, Stumpf, David K., Titan II, The University of Arkansas Press, Fayetteville, Arkansas, 2000. The launch was part of the Anti Ballistic Missile program and was witnessed by an entourage of general officers and congressmen. The second stage then separated and began its burn, but due to the improper speed and attitude at separation, the guidance system malfunctioned and caused an unstable flight trajectory. The last Titan II missile, located at Silo 373-8 near Judsonia, Arkansas, was deactivated on 5 May 1987.

Finally, the supports that held the missile in place inside the silo would be released using pyrotechnic bolts, allowing the missile to lift off. This is an approximately 1:20 scale model of the Gemini-Titan II rocket, used by the National Aeronautics and Space Administration (NASA) to launch all ten manned spacecraft in the Gemini program during 1965-1966. Fortunately, the Titan's errant flight came to an end after flipping almost completely upside-down which caused the second stage to separate from the stack. The fuel tank, also a welded structure, consists of a forward dome, tank barrel, aft cone, and internal conduit. Originated From: United States It would carry a larger warhead over a greater range with more accuracy and could be fired more quickly. By the mid-1970s, the original AC Delco inertial guidance system had become obsolete and spare parts could no longer be obtained for it, so the guidance packages in the stock of Titan missiles were replaced by the Universal Space Guidance System. Next Group of Photos 61-2738/60-6817 in the silo at the. Inside was a plastic "cookie", with the five letters written on it. 62-12560 top half of Stage 1 was recovered offshore following its launch and is on display at the Alabama Space & Rocket Center in Huntsville, Alabama. Titan II rocket, lifting off from an underground silo. BSD decided that 0.6 Gs was good enough despite NASA's goal of 0.25 Gs and they stubbornly declared that no more resources were to be expended on it. The Titan II also used storable propellants: Aerozine 50 fuel, which is a 1:1 mixture of hydrazine and unsymmetrical dimethylhydrazine (UDMH), and dinitrogen tetroxide oxidiser. The inadvertent rolling motion of the vehicle may have also prevented a worse disaster as it added stability and prevented it from colliding with the silo walls as it ascended. The first stage consists of one ground ignited Aerojet LR-87 liquid propellant rocket engine (with two combustion chambers and nozzles but a single turbopump system), while the second stage consists of an Aerojet LR91 Liquid-propellant engine.[42]. The message also contained a six-letter code that unlocked the missile. Once an order was given to launch, launch codes were sent to the silos from SAC HQ or its backup in California. I tried to have the characteristics be as accurate as possible, for example the weight of the rocket is exactly 154.000 kg like the real life counterpart Don't forget to upvote if you liked it. 61-2738/60-6817 resides in the silo at the Titan Missile Museum (ICBM Site 571-7), operated by the Pima Air & Space Museum at Green Valley, south of Tucson, Arizona, on Interstate-19.[39]. Titan II(23)G launching Clementine Moo… This code was entered on a separate system that opened a butterfly valve on one of the oxidizer lines on the missile engines. The Titan II ICBM was the successor to the Titan I, with double the payload. Finally, B-34 Stage 2 was delivered from Norton Air Force Base to Martin Marietta on 28 April 1986, but was not modified to a G, nor was it listed as arriving or being destroyed at the 309th Aerospace Maintenance and Regeneration Group at Davis–Monthan Air Force Base; it is therefore unaccounted for within the open source public domain. Stage I contained three gyros and the Autopilot. No. Embedded in the thirty-five letter code sent from HQ was a seven-letter sub-code. The engines were merely given a brief static firing to verify their functionality. GLV-5, AF Ser. All Gemini flights were launched from Launch Complex 19 (LC-19) at Cape Kennedy Air Force Station in Florida. [36], Number of Titan II missiles in service, by year:[citation needed], Each Titan II ICBM wing was equipped with eighteen missiles; nine per squadron with one each at dispersed launch silos in the general area of the assigned base. [citation needed], On 24 August 1978, SSgt Robert Thomas was killed at a site outside Rock, Kansas when a missile in its silo leaked propellant. The interstage structure, oxidizer tank forward skirt, and inter-tank structure are all fabricated assemblies using riveted skin, stringers and frame. The transition section, inter-tank structure and aft skirt are all fabricated assemblies using riveted skin, stringers and frame. No. The rocket was used for national defense and space exploration. • Former space engineer and rocket scientist James Oberg said the Gemini 4 was the only one of 10 manned flights in which a rendezvous was attempted (and nearly accomplished) with a beer can-shaped target (ie: the upper stage of the Titan II rocket that had been floating in space for 50 hours). The Titan II Launch Complex 374-7 in Southside (Van Buren County), just north of Damascus (Van Buren and Faulkner counties), became the site of the most highly publicized disaster in the history of the Titan II missile program when its missile exploded within the launch duct on September 19, 1980. Each stage is 10 feet (3.0 m) in diameter and has fuel and oxidizer tanks in tandem, with the walls of the tanks forming the skin of the missile in those areas. No. This was followed by a launch from VAFB on 27 April when Missile N-8 flew successfully. The Titan II was the largest ICBM ever deployed by the U.S. Air Force. The codes were compared to each other and if they matched, both operators proceeded to a red safe containing the missile launch documents. The Martin Company realized that the Titan I could be further improved and presented a proposal to the U.S. Air Force for an improved version. Aside from pogo oscillation (the nickname NASA engineers invented for the Titan's vibration problem since it was thought to resemble the action of a pogo stick),[8] the Titan II was experiencing other teething problems that were expected of a new launch vehicle. 61-2756, was given to the U.S. Space & Rocket Center in Huntsville, Alabama, in the 1970s. The second stage was manually destroyed by the Range Safety officer shortly thereafter. INTRODUCING TITAN II. Two men escaped alive, both with injuries due to the fire and smoke, one by groping in complete darkness for the exit. See squadron article for geographic locations and other information about the assigned launch sites. On the other hand, the exact reason for pogo was still unclear and a vexing problem for NASA. Before you start, set your desired heading At the Titan Missile Museum, near Tucson, Arizona, visitors journey through time to stand on the front line of the Cold War. Air Force Base Silo Deactivation date ranges: Official Count: 108 Titan-2 'B' Series Vehicles were delivered to USAF: 49 Test launches, 2 Silo losses, 13 Space launches, 6 in museums, 37.5 destroyed at AMARC, +.5 (one second stage missing B-34)=108. Many of these flights took place at Cape Canaveral due to the Titan II’s selection for usage in NASA’s Gemini program.4, The Titan II entered active service with the U.S. Air Force in 1963.5, Much like its predecessor, the Titan II was primarily valued for its quick counter-strike capability. 8-86): Air Force Facility Site 8 (571-7)", "Martin Marietta SM-68B/LGM-25C Titan II. [16], The mishap was traced to an unforeseen design flaw in the silo's construction – there was not enough room for the umbilicals to detach properly which resulted in wiring being ripped out of the Titan. One missile, B-108, AF Ser. External conduits are attached to the outside surface of the tanks to provide passage for the wire bundles and tubing. This site established July 6, 1995. With their warheads removed, the deactivated missiles were initially placed in storage at Davis–Monthan Air Force Base, Arizona, and the former Norton Air Force Base, California, but were later broken up for salvage by 2009. Gemini was also the first program to use the newly built Mission Control Center at the Houston Manned Spacecraft Center for flight control. Most of the Titan rockets were the Titan II ICBM and their civilian derivatives for NASA. However, that warhead was never developed or deployed. The missile was upgraded with an improved guidance system in 1979.14 The missile used a single Mk 6 Reentry Vehicle (RV) which carried a W-53 9.0 MT nuclear warhead. Its inertial guidance system gave an accuracy of 900 meters CEP and was capable of making in-flight corrections without ground control input. The next flight was Missile N-22, a silo test from Vandenberg Air Force Base on 20 June, but once again the second stage lost thrust due to a gas generator restriction. The Martin Marietta Astronautics Group was awarded a contract in January 1986 to refurbish, integrate, and launch fourteen Titan II ICBMs for government space launch requirements. This warhead was guided to its target using an inertial guidance unit. NASA's Clementine spacecraft was launched aboard a Titan 23G in January 1994. While this did not affect missile launches for the Air Force, NASA officials were concerned that this phenomenon would be harmful to astronauts on a crewed Gemini flight. The program carried the conditions that the ICBM program retained first priority and was not to be delayed by Gemini, and that General McCoy would have final say on all matters. The Autopilot attempted to keep the missile straight during first stage flight and sent commands to the Inertial Measurement Unit (IMU) on the 2nd stage. Impact occurred only 700 miles (1,100 km) downrange. If the cookie matched the remaining five digits in the sub-code, the launch order was authenticated. By the mid-1980s, with the stock of refurbished Atlas E/F missiles finally starting to run out, the Air Force decided to reuse decommissioned Titan IIs for space launches. The use of storable propellants enabled the Titan II to be launched within 60 seconds directly from within its silo. The Titan I, whose liquid oxygen oxidizer must be loaded immediately before launching, had to be raised from its silo and fueled before launch.
