Launch Complex 13 (LC-13) at Cape Canaveral Air Force Station, Florida is leased by SpaceX for use as their east-coast landing location for returning Falcon 9 and Falcon Heavy launch vehicle booster stages. It was originally used for test launches of the Atlas ICBM and subsequently for operational Atlas launches from 1958 to 1978.〔 Since then it has been deactivated. It is the third-most southerly of the complexes known as Missile Row, lying between LC-12 and LC-14. It was the most-used and longest-serving of the original four Atlas pads.〔The original four Atlas pads were LC-11, 12, 13 and 14.〕 On 16 April 1984, it was added to the US National Register of Historic Places; however it was not maintained and gradually deteriorated. On 6 August 2005 the mobile service tower was demolished as a safety precaution due to structural damage by corrosion.〔(【引用サイトリンク】title=Spaceflight Now - Breaking News - Historic Cape Canaveral launch pad toppled )〕 〔The structure was so unstable that it could not be safely dismantled and had to be toppled by a controlled explosion before it could be taken apart. This has since become the standard method of dismantling launch complexes at Cape Canaveral and was used in the demolition of LC-41, LC-36 and LC-40.〕 The blockhouse was demolished in 2012.〔(【引用サイトリンク】title=Launch Complex 13 )〕 ==Construction== Together with Launch Complexes 11, 12 and 14, LC-13 featured a more robust design than many contemporary pads due to the greater power of the Atlas compared to other rockets of the time. It was larger and featured a concrete launch pedestal that was tall and a reinforced blockhouse. The rockets were delivered to the launch pad by a ramp on the south side of the launch pedestal.〔(【引用サイトリンク】title=Wikimapia - LC-13 from Google Satellite )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cape Canaveral Air Force Station Launch Complex 13」の詳細全文を読む スポンサード リンク
