This is a scarce World War II (WWII) era 1945 map of Bombay (Mumbai) harbor and vicinity issued by the U. S. Navy Hydrographic Office. It covers the western coast of what was then British India, from Arnala Island to Khanderi Island and inland as far as Kalyan and Bava Malang (Baba Malang) or Malanggad. Based on British surveys between 1855 and 1921 with additions to 1934, this chart offers extraordinary detail throughout including topography. The map shows considerable inland detail for a nautical chart, noting railways, rivers, towns, hills, etc. Bombay City in particular is beautifully detailed with streets, individual buildings, docks and forts noted. Countless depth soundings are noted in fathoms. The chart also notes several lights, buoys, radio beacons and notes on tides. This is the sixth edition of the chart first published in 1908. This particular map was printed in 1944 with small corrections and contains manuscript corrections dating to 1945. This map was prepared in 1944 as chart no. 2460 by the U.S. Navy at the Hydrographic Office under the authority of the Secretary of the Navy.
The U.S. Navy Hydrographic Office is a branch of the United States Navy founded in 1830 to compile non-domestic hydrographic and bathymetric surveys. These surveys are conducted by the U.S. Naval Oceanographic Office, which started with the establishment of the Depot of Charts and Instruments in 1830. In 1854 the U.S. Navy Oceanographic Office was renamed the U.S. Naval Observatory and Hydrographical Office. The hydrographic portion became the U.S. Naval Hydrographic Office under the Hydrographer of the Navy. In 1962, under the Kennedy administration, the name was again changed to the U.S. Naval Oceanographic Office in 1962. That office, as a matter of historical and semantic interest, and the U.S. Naval Observatory are still part of the command overseen by the "Oceanographer of the Navy" with headquarters at the Naval Observatory in Washington D.C.
