WWII U.S. Navy Pacific Ocean Cloth Navigation Chart-Ocean Currents Map-Original

Original WWII U.S. Navy Pacific Ocean navigation chart, printed on cloth for durability at sea. This Chart shows detailed ocean currents, directional flow, velocity data, seasonal variations and navigational grid references across the Pacific theater, including areas around Japan, Okinawa, and the Bonin Islands. 

Produced during WWII for naval operational use, this cloth chart features period-correct markings and a visible “RESTRICTED” designation. Cloth charts were issued for shipboard and aviation use due to their resistance to moisture and tearing. 

Condition is good for age with heavy folding creases, age related discoloration, and wear consistent with wartime use. No Tears or losses noted. All printed details remain legible.
