They were in the forefront of the submarine force’s success of near-destruction of the Japanese merchant fleet and significant reduction of the Imperial Japanese Navy. The Balao-class submarines entered service in mid-1943. One Balao submarine, USS Tang (SS-306), actually achieved a depth of 612 feet, as stated by the Tang’s commander Richard O’Kane in his book, Clear the Bridge!: The War Patrols of the U.S.S. It increased their test depth to 400 feet.

The major improvements over the previous Gato-class was the upgraded thicker, higher yield strength steel and the pressure hull skin and frame. Approximately 265 were ordered and more than 119 were completed between 19. Of all the classes of submarines during World War II, the Balao-class contributed the most submarines to the submerged fight. depth charge, also called depth bomb, a type of weapon that is used by surface ships or aircraft to attack submerged submarines.

Upgraded to one 5 inch 25-caliber, one 40 mm and one 20 mm. Originally, one 4 inch 50-caliber and two 20 mm. In fact, the Los Angeles-class submarines have a crush depth of around 2,000 feet, which means they. But they’re capable of going much deeper than that. Navy’s Los Angeles- class submarines, the most common type of submarine in the fleet, are designed to operate at depths of up to 800 feet. By the end of the war, Bowfin was using the Mark 18 electric torpedo and Mark 27 acoustic torpedo, nicknamed "cutie." The answer, it turns out, is pretty deep. After the search and rescue efforts lasted a few days, debris of the Indonesian submarine was found in 838 meters depth. Primary torpedoes used were the Mark 14 and Mark 23, both steam-driven.
