U.S. Air Force Long Range Navigation Chart Arabia (LR-25), Scale 1:3,000,000, Third Edition - July 1948 Aeronautical Chart Service, US Air Force (USAF)

Colour printed paper map 132x103cm. Very good, neatly folded. First published in 1944, revised December 1947, lithographed by AMS 5-48, with aero overprint by ACS 8-48. This is still labelled for Palestine. Centred on the Saudi-Iraq border, coverage is bounded by the Dardanelles (NW), Oxus (NE), Oman's Masirah Island (SE), and Dongola (SW). This covers the Arabian Peninsula as far south as Kunfida, including much of the Red Sea, the whole of the Persian Gulf and Gulf of Oman. Colour tinted for altitude with contours, spot heights, notes about terrain, 4 grades of settlement, streams and shorelines, railroads, aircraft facilities (types of airport, airfields, seaplane ports, landing grounds, anchorages), airfield data, air navigation lights, and radio facilities. Landing grounds include those at pumping stations along the Iraq Petroleum Company Pipeline. Prohibited Areas are circled around several Saudi cities (Riyadh, Mecca, Medina, Hail, Al Jauf), Baghdad (also a Danger Zone), strategic locations in Egypt (Port Said, El Arish, and settlements up the Nile), and India's borders with Afghanistan and Iran. Restricted Areas are shown in Turkey. Notes about terrain in Saudi focus on water supply and quality in remote areas. International boundaries are also shown. Maps of this kind typically label those in eastern and southern Arabia as approximate or undefined, but this one has some strangely placed lines. These include a straight Saudi - Aden Protectorate line dropping due south from Uqair on the Gulf of Bahrain off the lower edge; an Oman - Aden Protectorate line extending well into Oman and including the Trucial States; and an Omani border with Qatar. This predates the Buraimi Dispute (there is no label for Buraimi), and may be an attempt to define the extent of British influence.
