K-2 Air Base is a former Iraqi Air Force base in the Salah al-Din Governorate of Iraq. It was captured by Coalition forces during Operation Iraqi Freedom in 2003. ==Overview== K-2 Airbase is located in Northern Iraq. The airfield is served by one runway 9,870 feet long. The airbase is named after the K-2 oil pipeline pumping station. Not much is known about the base, but it was established near the pumping station on the oil pipeline into Turkey sometime in the 1930s, and became known as a Mirage F.1EQ base in the 1980s. It was one of several Iraqi Air Force airfields which were rebuilt in the mid-1970s under project "Super-Base" in response to the experiences in Arab-Israeli wars in 1967 and 1973. Originally, 13 airfields were re-built by British contractors, and on all of them a number of hardened aircraft shelters were also built. Subsequently companies from Yugoslavia - previously engaged in building bridges in Iraq - became involved. Due to their specific construction of these airfields - which included taxi-ways leading right out of Hardened Aircraft Shelters (HAS) and laid diagonally to the runways - they became known as "Trapezoids" or "Yugos". The facilities were divided into two categories: "surface" and "underground". The "surface" facilities were actually the "softest", and included maintenance hangars of metal construction and HAS of concrete construction. In total, the Yugoslavs built no fewer than 200 HAS on different airfields in Iraq during the 1980s. The protection of each HAS consisted of one-metre-thick concrete shells, reinforced by 30 cm thick steel plates. There was only one entrance and this was covered by sliding doors made of 50 cm thick steel armoured plate and concrete. The HASs were usually built in small groups - seldom more than five, with each group sharing the same water and power supply, besides having its own backup gasoline-powered electrical generator and a semi-automatic aircraft-refuelling system. In addition, underground facilities that could shelter between four and ten aircraft on average were constructed. In order to build these, the Yugoslavs used equipment and construction techniques identical to those used in underground oil-storage depots, additionally concealing the extent and the true purpose of the whole project. The underground facilities were all hardened to withstand a direct hit by a tactical nuclear bomb, buried up to 50 metres below the ground, and consisted of the main aircraft "hangar" (in several cases with two floors connected by 40ts hydraulic lifts), connected with operations, maintenance, and logistical facilities via underground corridors. 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「K-2 Air Base」の詳細全文を読む スポンサード リンク
