…The first full-scale deep-sea submersible was the FNRSII, built in 1948 by A. Piccard using a pressure sphere with a diameter of 2m. The French Navy's four-man FNRSIII, an improved version of the FNRSII, recorded a diving depth of 2,100m in 1953 and 4,050m the following year. In 1953, Italy built the Trieste, a deep-sea submersible of the same type as the FNRSII, which later became the property of the US Navy. In 1960, Piccard's son, J.
