It would carry a larger warhead over a greater range with more accuracy and could be fired more quickly. , 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. 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. Titan II missiles were designed to be launched from underground missile silos that were hardened against nuclear attack. 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. A new set of engines had to be ordered from Aerojet, and the missile lifted off from LC-16 on the morning of 25 July. The blast completely destroyed the silo and sent the 750-ton silo door flying 200 meters and 20-ton fragments from the flame deflectors over 500 meters from the silo. , The next three launches Missile N-5 (12 September), N-9 (12 October), and N-12 (26 October), were entirely successful, but the nagging pogo problem remained and the booster could not be considered man-rated until this was fixed. The keys had to be turned within two seconds of each other, and had to be held for five seconds. This was intended to allow for the United States to ride out a nuclear first strike by an enemy and be able to retaliate with a second strike response. It used an IMU (inertial measurement unit, a gyroscopic sensor) made by AC Spark Plug deri… The Titan I, whose liquid oxygen oxidizer must be loaded immediately before launching, had to be raised from its silo and fueled before launch. It weighed 149,700 kilograms when fully fueled and had a range of 15,000 km. 61-2768 at the Stafford Museum, Oklahoma. After many failed tests and repeated design changes, the G forces stemming from the pogo effect eventually fell within the strict limits set by NASA and production of a modified Titan II was ordered.12 These modified versions of the Titan II were used by NASA as the launch vehicle for the Gemini space program. This site established July 6, 1995. Titan II. In addition, Stage II contains the flight control system and missile guidance system. The 54 Titan IIs had been fielded along with a thousand Minutemanmissiles from the mid-1960s through the mid-1980s. No. A total of 282 Titan IIs were launched between 1962 and 2003, of which 25 were space launches. The ISDS (Inadvertent Separation Destruct System) then activated and blew up the first stage. 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. Named after the NASA rocket that launched the Gemini manned space missions, the Titan II has arrived to blast your tone into the stratosphere! The LGM-25C ballistic missile (Titan IIc) consisted of a two-stage, liquid rocket-engine-powered vehicle and a reentry vehicle. A Titan II missile test launches . In addition, the oxidizer feedlines were made of aluminum instead of steel. The missile was armed with a 9 megaton nuclear warhead, the most powerful warhead ever fielded by the United States. Gemini was also the first program to use the newly built Mission Control Center at the Houston Manned Spacecraft Center for flight control. The message also contained a six-letter code that unlocked the missile. N-10 AF Ser. INTRODUCING TITAN II. Hypergolic fueled rocket nozzles of the Titan II rocket. After the two accidents in 1978 and 1980, respectively, deactivation of the Titan II ICBM system finally began in July 1982. Those payloads included the USAF Defense Meteorological Satellite Program (DMSP), NOAA weather satellites, and NASA's Gemini crewed space capsules. The transition section, inter-tank structure and aft skirt are all fabricated assemblies using riveted skin, stringers and frame. Because the computer had not sent a manual cutoff command, reentry vehicle separation and vernier solo phase did not occur. External conduits are attached to the outside surface of the tanks to provide passage for the wire bundles and tubing. All rights reserved. 1. Status: Obsolete , Vehicle N-13 was launched 13 days later and carried no standpipes, but it did have increased pressure in the first stage propellant tanks, which did cut down on vibration. Missile Threat is a product of the Missile Defense Project at the Center for Strategic and International Studies. Flying atop a highly modified Titan II ICBM, NASA’s Gemini Manned Spaceflight program achieved 100 percent mission success . 2. Impact occurred only 700 miles (1,100 km) downrange. 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. Launch Weight: 149,700 kg Propulsion: Two-stage, liquid propellant 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. Its inertial guidance system gave an accuracy of 900 meters CEP and was capable of making in-flight corrections without ground control input. , A real Alert Real Response AAFM September 19999, Note: In 1959, a fifth Titan II installation comprising the 13th and 14th squadrons at the former Griffiss Air Force Base, New York, was proposed, but never constructed. The Martin company received a contract for the new missile, designated SM-68B Titan II, in June 1960. N-14 (9 May), flown from LC-16 at the Cape, suffered another early second stage shutdown due to a leaking oxidizer line. The consoles were too far apart for one person to turn them both within the required timing. Titan II was originally designed and used as an ICBM, but was later adapted as a medium-lift space launch vehicle to carry payloads to Earth orbit for the United States Air Force (USAF), National Aeronautics and Space Administration (NASA) and National Oceanic and Atmospheric Administration (NOAA). The third launch, Missile N-6 on 11 July, was completely successful. Titan II Rocket. It is able to lift approximately 1,900 kg (4,200 lb) into a circular polar low-Earth orbit. On these missiles, the nuclear warhead was removed and a new fairing was adapted that could carry a satellite into orbit, or in one case, the Clementine, an unmanned space probe to the moon. All Titan 23G missions were launched from Space Launch Complex 4 West (SLC-4W) on Vandenberg Air Force Base, under the operational command of the 6595th Aerospace Test Group and its follow-on organizations of the 4th Space Launch Squadron and 2nd Space Launch Squadron. , 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. The missiles had a two-stage liquid propellant design and reached a speed of 25 times the speed of sound by the time the engines cut off.15, Missile Defense Project, "Titan II," Missile Threat, Center for Strategic and International Studies, March 22, 2017, last modified June 15, 2018, https://missilethreat.csis.org/missile/titan-ii/.Copy. The first stage was powered by an LR87 engine (with two combustion chambers and nozzles, fed by a single set of turbomachinery), and the … , The Stage II airframe consists of a transition section, oxidizer tank, inter-tank structure, fuel tank and aft skirt. The Titan II was 50% heavier than the Titan I, with a longer first stage and a larger diameter second stage. The Titan II used LR-87-5 engines, a modified version of the LR-87, that relied on a hypergolic combination of nitrogen tetroxide and Aerozine 50 (a 50/50 mix of hydrazine and UDMH) for its oxidizer and fuel instead of the liquid oxygen and RP-1combination used in the Titan I. NASA's Clementine spacecraft was launched aboard a Titan 23G in January 1994. Broken Arrow incident involving a Titan II Intercontinental Ballistic Missile (ICBM). Unlike the Titan I, it used hydrazine-based hypergolic propellant which was storable and reliably ignited. One hundred and eight Titan-II ICBM (B-Types) were produced. The second stage was manually destroyed by the Range Safety officer shortly thereafter. The Titan suffered severe structural failure with both the hypergolic fuel tank and the oxidizer tank leaking and accumulating in the bottom of the silo. With this considerable potential for catastrophic accident, large propellant spills were rare in the Titan II program. This preserved Titan II missile site, officially known as complex 571-7, is all that remains of the 54 Titan II missile sites that were on alert across the United States from 1963 to 1987. Share Comments (0) This project doesn't have any comments yet. The Titan II GLV (Gemini Launch Vehicle), was developed to launch Gemini spacecraft.

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. Then the silo doors would slide open, giving off a "SILO SOFT" alarm inside the control room. Warhead: 9.0 mT Nuclear Aircraft of comparable role, configuration, and era. Eighteen of the missiles were on 24-hour continuous alert surrounding Davis–Monthan Air Force Base near Tucson, Arizona. Titan III C - Titan II core with two solid rocket strap-ons. When spares for this system became hard to obtain, it was replaced by a more modern guidance system, the Delco Universal Space Guidance System (USGS). NASA chose this powerful booster to propel the Gemini spacecraft into orbit and my town was, for a little while, one of the key locations in the Space Race of the 1960s. During development, the missile met the objectives set by the Air Force for use as an ICBM fairly early but ran into trouble meeting the criteria set by NASA for a manned space launch platform. 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. , On 23 June 1975, one of two engines failed to ignite on a Titan II launch from Silo 395C at Vandenberg AFB in California. Due to the high yield of the warhead and the accuracy of the missile’s guidance system, it was possible for the Titan II to destroy hardened targets.

Missile Threat brings together a wide range of information and analyses relating to the proliferation of cruise and ballistic missiles around the world and the air and missile defense systems designed to defeat them. The Titan II ICBM was the successor to the Titan I, with double the payload. First stage performance was near-nominal, but the second stage developed low thrust due to a restriction in the gas generator feed. This flight had been scheduled for launch in early 2001, but persistent problems with the booster and satellite delayed it over two years. All models made by me and most textures from quixel. Of the 13 launches, there was one failure, when a launch of a Landsat satellite in 1993 ended in a useless orbit due to a malfunction of the satellite kick motor. Titan II GLV.  Author Eric Schlosser published a book centered on the accident, Command and Control: Nuclear Weapons, the Damascus Accident, and the Illusion of Safety, in September 2013. The modified Titan II SLVs (Space Launch Vehicles) were launched from Vandenberg Air Force Base, California, up until 2003. The Titan II was in service from 1963 to 1987. The computer system compensated by running the engine for an additional 111 seconds, when propellant depletion occurred. On the other hand, the exact reason for pogo was still unclear and a vexing problem for NASA. The reentry vehicle was found and dredged up along with parts of the second stage, but the guidance system was not recovered. The Titan II was a two-stage intercontinental ballistic missile developed by the U.S. Air Force. , The first flight of the Titan II was in March 1962 and the missile, now designated LGM-25C, reached initial operating capability in October 1963. The safe contained a number of paper envelopes with two letters on the front. Possessed By: United States The missile was 31.3 m long and 3.05 m wide. On 29 May, Missile N-20 was launched from LC-16 with a new round of pogo-suppressing devices on board. A removable cover for tank entry is located on the forward dome of each tank. 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 missile guidance system enables the shutdown and staging enable relay to initiate Stage I separation. Standing 103 feet tall and weighing a colossal 330,000 pounds, it had a range of up to 9,300 miles away (3,000 miles greater than the Titan I). The missile had a diameter of 3.05 m, a length of 31.30 m and a launch weight of 149,700 kg. 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. Gemini Titan II Model Rocket: https://www.ebay.com/itm/Gemini-Titan-model-rocket-parts-kit-size-BT-70/283975738360 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. FUZZ, DISTORTION, OVERDRIVE… The Titan II is a unique discrete circuit using silicon transistors. Diameter: 3.05 m  Due to the warhead's built-in safety features, it did not detonate and was recovered about 300 feet (100 m) away. © 2021 by the Center for Strategic and International Studies. Round of applause for our sponsors Titan II Rocket by hypelights. At this point, BSD suspended further flights. The Titan II on display is the last variant of the Titan II family, the Space Launch Vehicle (SLV). An Air Force airman was killed, and the complex was destroyed. Twelve Gemini missions were flown, ten of which were manned, in preparation for the Apollo space program. 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. 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), the Titan II was experiencing other teething problems that were expected of a new launch vehicle. The rocket first flew on 8 April 1964. Titan II launch with Gemini 5. The launch was part of the Anti Ballistic Missile program and was witnessed by an entourage of general officers and congressmen. This warhead was guided to its target using an inertial guidance unit. , Number of Titan II missiles in service, by year:, 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. Titan II rockets were later used in the mid-21st century, during World War III, as a type of nuclear missile. The Titan II used the LR-87-5 engine, a modified version of the LR-87, that used a hypergolic propellant combination of nitrogen tetroxide for its oxidizer and Aerozine 50 (a 50/50 mix of hydrazine and UDMH) instead of the liquid oxygen and RP-1 propellant of the Titan I. 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. The safe featured a separate lock for each operator, who unlocked it using a combination known only to him or herself. Titan II rocket launching Gemini 11 spacecraft (Sept. 12, 1966) 4. No. However, that warhead was never developed or deployed. The IMU would compensate and send steering commands to the engine actuators. This was followed by a launch from VAFB on 27 April when Missile N-8 flew successfully. 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. Titan’s exemplary record established a standard for perfection, safely launching two-man crews into orbit 10 times from 1965-66, one of the most dynamic and fast-paced periods in the Space Race. The LGM-25C Titan II was the last liquid-fueled intercontinental ballistic missile (ICBM) built by the United States in order to deter the Soviet Union.  The missile survived and was undamaged. During the Black Mesa Incident several scientists at the facility prepare to launch a Satellite Delivery Rocket in an attempt to close the dimensional rift, only to be stopped by HECU personnel, leaving Gordon Freeman to complete the task himself. 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. Because of the hypergolic propellants involved, the entire missile exploded a few hours later, killing an Air Force airman, SrA David Livingston, and destroying the silo (374-7, near Damascus, Arkansas). Their hypergolic nature made them dangerous to handle; a leak could (and did) lead to explosions, and the fuel was highly toxic. Gemini-Titan II - used to launch two-man Gemini Spacecraft. It was solved by adding extra lanyards to the umbilicals so they would have sufficient "play" in them to separate without damaging the missile. The 54 deployed Titan IIs formed the backbone of America's strategic deterrent force until the LGM-30 Minuteman ICBM was deployed en masse during the early to mid-1960s. Leadership within the USAF and SAC were reluctant to retire the Titan II because while it made up only a small fraction of the total number of missiles on standby, it represented significant portion of the total megatonnage that was deployed by Air Force ICBMs. Titan II(23)G launching Clementine Moo… The 1988 television movie Disaster at Silo 7 is loosely based on the event. Another airman, A1C Erby Hepstall, later died from lung injuries sustained in the spill.. All twelve Gemini capsules, including ten crewed, were launched by Titan II launchers. The last Titan II missile, located at Silo 373-8 near Judsonia, Arkansas, was deactivated on 5 May 1987. Titan II ICBM Web Page This site visited times since May 27th, 2011. The Titan II was the largest and heaviest missile ever built by the United States. by hypelights on 15 Dec 2020 Made for another contest, the theme was destruction. The codes were compared to each other and if they matched, both operators proceeded to a red safe containing the missile launch documents. 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. This was the same missile that had been in the silo during the deadly fire at site 373-4, refurbished and relocated after the incident. USAF. A reliability review of the Titan II launch vehicle engine system was held in Sacramento, California, at Aerojet-General's Liquid Rocket Plant, the site where the engines were being developed. Forty-nine were launched for testing at Vandenberg Air Force Base from 1964 to 1976. 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. The missile guidance computer (MGC) was the IBM ASC-15. An umbilical cord failed to separate cleanly, ripping out wiring in the second stage which not only cut power to the guidance system, but also prevented the range safety charges from being armed. Sheehan, Neil, “A Fiery Peace in a Cold War: Bernard Schriever and the Ultimate Weapon.” New York: Random House. The Titan II was an intercontinental ballistic missile (ICBM) and space launcher developed by the Glenn L. Martin Company from the earlier Titan I missile. Two were lost in accidents within silos.  The Titan II was originally expected to be in service for only 5–7 years, but ended up lasting far longer than anyone expected in part because of its large size and throw weight. Of these, 38 and one second stage were stored outside at the Aerospace Maintenance and Regeneration Center (AMARC), now known as the 309th Aerospace Maintenance and Regeneration Group (309 AMARG), adjacent to Davis–Monthan Air Force Base, to await final destruction between 2004 and 2008. 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.
