Tactical Commanders' Terrain Analysis Ras Tanura Area Terrain Analysis Map AP-1-380-46-65-INT. TacCTA Ras Tanura Saudi Arabia.

Very good. Light wear along original fold lines. Size 36.25 x 28 Inches. This is a 1965 Tactical Commanders' Terrain Analysis (TacCTA) map of Ras Tanura, Saudi Arabia, prepared by the Army Map Service for the Defense Intelligence Agency. The area is home to a large Saudi Aramco oil refinery and port, the main avenue for Saudi Arabia's oil exports, and the map would have been vital for any military operation that might take place there. A Closer Look This map covers Ras Tanura and environs on the east coast of Saudi Arabia. A grid overlies the map, dividing it into squares of 100,000 meters, as explained in the diagram at the bottom. Color-shading and a series of numbers and letters are used to indicate the nature of terrain, its suitability for trucks and tanks, and the level of cover and concealment (generally very little). A similar table at the bottom-right gives related information for airstrips, beaches, and piers, which would be essential in any military operation. (The most favorable landing sites are marked in blue around the refinery and adjacent settlements.) Additional information on roads, terrain, flora, settlements, and human-built structures such as mosques, cemeteries, and wells is indicated according to the legend at bottom-left. As on land, remarkably detailed information is provided on the waters around Ras Tanura, including soundings, bottoms, and the location of fishing weirs. The verso provides additional information and photographs, focusing on the refinery and potential landing zones for ships and airplanes. Mapping Military Intelligence This map was produced by the Defense Intelligence Agency (DIA), created in 1961 and housed within the Department of Defense under the leadership of the Under Secretary of Defense for Intelligence. The agency is thus independent of both the military services (whose intelligence outfits it took over many functions from) and the Central Intelligence Agency. The DIA is tasked with providing intelligence information to the Secretary of Defense, Joint Chiefs of Staff, and military commanders. The present map reflects the assiduousness of the agency's work, with granular detail and analysis that would be critical in any military operation at Ras Tanura. Given the importance of Ras Tanura for global oil supply and the highly unsettled state of regional politics (including a dispute within the Saudi monarchy between King Saud and his half-brother Faisal, who deposed the former in 1964) set against the background of the Cold War (1947 - 1991), one can imagine that this map would have been essential for safeguarding the Aramco facilities at Ras Tanura in the event of a military conflict. Ras Tanura and the Oil Industry Ras Tanura is a settlement set on a peninsula jutting out into the Persian Gulf, located between Bahrain and Kuwait, forming the top portion of Tarut Bay. Its history is closely tied to the oil industry as it is home to major refinery and port facilities. When large quantities of oil were first discovered at nearby Dammam in 1938, the California Arabian Standard Oil Company (CASOC), forerunner to Saudi Aramco, built a pipeline to Ras Tanura, and a refining plant was put into operation. During World War II (1939 - 1945), a new, wider pipeline and a much larger refinery were constructed to support the war effort. Export capacity continued to expand, reaching 1 million barrels per day in 1971 and roughly 6 million barrels per day nowadays, some 90% of Saudi Arabia's oil exports, making Ras Tanura the largest oil port in the world. CASOC/Aramco also built a relatively luxurious residential compound near the refinery at Najmah (Nejma here) for American workers, which has in the decades since come to house a more cosmopolitan mix of employees, including many Saudis. The adjacent town of Rahima (Rahaima here) historically housed Saudi and other non-Western workers, though these divisions were not always absolute. Other nearby facilities, such as a hospital and golf course.…
