10, These accidents sparked a 1980 congressional investigation into potential hazards which led to the U.S. moving away from liquid-fueled ballistic missiles and the eventual retirement of the Titan II.11. 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. 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. The engines were merely given a brief static firing to verify their functionality. When that time was reached, the two operators inserted keys into their respective control panels and turned them to launch. USAF. The missile was 31.3 m long and 3.05 m wide. [2] Stage I contained three gyros and the Autopilot. A total of 12 missions, all carrying Gemini spacecraft, were successfully launched from launch complex 19 at … Sutton, George P., “History of Liquid Propellant Rocket Engines,” American Institute of Aeronautics and Astronautics, Reston, VA, United States Air Force, “T.O. All were launched from the then-Cape Kennedy Air Force Station in 1964–66. [6], The Department of Defense predicted that a Titan II missile could eventually carry a warhead with a 35 megaton yield, based on projected improvements. This site established July 6, 1995. The missile was 31.3 m long and 3.05 m wide. Titan III C - Titan II core with two solid rocket strap-ons. However, the United States’ nuclear doctrine planned on using the Titan IIs and other ICBMs as a counter-value deterrent which targeted large Soviet military bases and civilian population centers.8, While in service, there were a number of fatal accidents involving the missile. While previous second stage problems were blamed on pogo, this could not be the case for N-15. 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. 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. The missile was armed with a 9 megaton nuclear warhead, the most powerful warhead ever fielded by the United States. Gordon manages to take down the soldiers and launch the rocke… Developed as an intercontinental ballistic missile, the Titan II also served as a launch vehicle for the Gemini manned spacecraft missions and … Launch Weight: 149,700 kg The rocket first flew on 8 April 1964. Titan II carried the largest single warhead of any American ICBM. The deadliest of these occurred on August 9, 1965 in Searcy, Arkansas when welding fuel ignited during a silo upgrade program. Because of the volatility of the liquid fuel and the problem with aging seals, the Titan II missiles had originally been scheduled to be retired beginning in 1971. Warhead: 9.0 mT Nuclear The Titan II was a two-stage intercontinental ballistic missile developed by the U.S. Air Force. [17], While N-18 flew successfully from the Cape on 21 March, N-21 suffered another second stage failure after having been delayed several weeks due to another episode of the first stage thrust chambers breaking off prior to launch. [26] The missile survived and was undamaged. A large number of civilian contractors were evacuated from the Command and Control Bunker. 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. 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. In addition, the oxidizer feedlines were made of aluminum instead of steel. No. 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). It weighed 149,700 kilograms when fully fueled and had a range of 15,000 km. FUZZ, DISTORTION, OVERDRIVE… The Titan II is a unique discrete circuit using silicon transistors. GLV-5, AF Ser. These were designated Titan 23G. The reentry vehicle was found and dredged up along with parts of the second stage, but the guidance system was not recovered. The remaining thirty-six missiles were equally divided between Little Rock Air Force Base in Arkansas, and McConnell Air Force Base in Wichita, Kansas, and also placed on continuous 24-hour alert, making for a total of fifty-four operational combat asset Titan IIs. Once an order was given to launch, launch codes were sent to the silos from SAC HQ or its backup in California. The Titan 23G ended up being less of a cost-saving measure than anticipated as the expense of refurbishing the missiles for space launches turned out to be more than the cost of flying a brand-new Delta booster. [27], On 23 June 1975, one of two engines failed to ignite on a Titan II launch from Silo 395C at Vandenberg AFB in California. The missile lifted with a continuous uncontrolled roll, and at about T+15 seconds, when the pitch and roll program would normally begin, it began a sudden sharp downward pitch. 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. The missile had a diameter of 3.05 m, a length of 31.30 m and a launch weight of 149,700 kg. Martin–Marietta thus added a surge-suppressor standpipe to the oxidizer feed line in the first stage, but when the system was tested on Titan N-11 on 6 December, the effect was instead to worsen pogo in the first stage, which ended up vibrating so strongly that unstable engine thrust resulted. 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. 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. 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. Ironically, the two largest oxidizer spills took place 14 years apart at the same site, Launch Complex 533-7, 381st SMW, McConnell AFB, Kansas. The Titan II rocket consisted of two stages. Forty-two B-series missiles remained, 41 full and one first stage at Norton Air Force Base, and the second stage at Martin. 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 interstage structure, oxidizer tank forward skirt, and inter-tank structure are all fabricated assemblies using riveted skin, stringers and frame. [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. 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. 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. The keys had to be turned within two seconds of each other, and had to be held for five seconds. B-14/20 AF Ser.
