Strategic Aerospace Division Vandenberg Air Force Base, California 395th Strategic Missile Squadron, 1 February 1959 – 31 December 1969 Operated 3 silos for technical development and testing, 1963–1969 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. Titan II missile disposition Thirty-three Titan-II Research Test (N-type) missiles were built and all but one were launched either at Cape Canaveral Air Force Station, Florida, or Vandenberg Air Force Base, California, in 1962–64. The surviving N-10, AF Ser. No. 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. Twelve Titan-II Gemini Launch Vehicles (GLVs) were produced. All were launched from the then-Cape Kennedy Air Force Station in 1964–66. The top half of GLV-5 62-12560 was recovered offshore following its launch and is on display at the U.S. Space & Rocket Center, Alabama. One hundred and eight Titan-II ICBM (B-Types) were produced. Forty-nine were launched for testing at Vandenberg Air Force Base from 1964 to 1976. Two were lost in accidents within silos. One B-2, AF Ser. No. 61-2756, was given to the U.S. Space & Rocket Center in Huntsville, Alabama, in the 1970s. The 56 surviving missiles were pulled from silos and individual base stores and all transferred to the then-Norton Air Force Base, California, during the 1980s. They were stored under plastic coverings and had helium pumped into their engine components to prevent rust. Norton Air Force Base buildings 942 and 945 held the missiles. Building 945 held 30 missiles, while Building 942 held 11 plus a single stage 1. The buildings also held extra stage engines and the interstages. 14 full missiles and one extra second stage had been transferred from Norton Air Force Base to the manufacturer, Martin Marietta, at Martin's Denver, Colorado, facility for refurbishment by the end of the decade. 13 of the 14 were launched as 23Gs. One missile, B-108, AF Ser. No. 66-4319 (23G-10 the spare for the 23G program), went to the Evergreen Aviation & Space Museum in McMinnville, Oregon. 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
