The USS Pasadena (SSN-75) is a Los Angeles class submarine and the third vessel of the United States Navy to be named after Pasadena, California. The second Pasadena (CL-6) was constructed by Bethlehem Steel Co. Wopschall and commissioned by Captain. In order to meet the urgent need for additional ships, the Cleveland class light cruisers were developed based on the Brooklyn class cruisers, with the main difference being the replacement of a 127 mm (5 inch) dual-purpose gun mount with one of the 6 inch (152 mm) main battery gun turrets.
The Cleveland class light cruisers were designed in the late 1930s, when the Second London Naval Treaty limited the displacement of light cruisers to 8,000 long tons (8,100 t). The ships' belt armor was 89 to 127 mm (3.5 to 5 inches) thick, and the thicker section in the center of the ship protected the ammunition magazines and the spaces of the propulsion machinery. In early July, the cargo ship began its first of four round-trip transatlantic voyages, two of which were in support of U. S.
forces in Europe. Later, Pasadena participated in the occupation of Japan; it became the flagship of Working Group 35.1 on August 23 and four days later it anchored in Sagami Bay, just outside Tokyo. After leaving the shipyard, it took part in training exercises in the area until September, when it sailed back to the Central Pacific. At sea for 80 days, Pasadena, as the flagship of CruDiv 17, participated in night bombardments of Minami Daito (March 28 and May 10) and continuous attacks on other Japanese positions in Okinawa and Kyushu (from April 1 to May 30).
In mid-January 1945, as the attack on Luzon progressed, the force sailed to the South China Sea and attacked Japanese installations and ships along the coast of Indochina and Formosa. In February, the ships, now TF 58, headed against the Japanese home islands and then headed south-east to cover landings on Iwo Jima. Soon after completing its last voyage, USS Pasadena was decommissioned in late April 1919 and transferred to United States Shipping Board custody. While deployed, it took part in several exercises with Royal Navies of Saudi Arabia, Oman and Australia; it was also first United States nuclear-powered attack submarine (SSN) to carry out exercises with Indian Navy in MALABAR Naval Exercise.
In 1948, USS Pasadena (CL-6) entered Pearl Harbor (Hawaii) during an NROTC midshipman cruise in summer. After completing its mission during World War I, it went on to serve during First World War with U. Navy.
