The FNRS-3 or FNRS III is a
bathyscaphe of the
French Navy. It is currently preserved at
Toulon. She set world depth records, competing against a more refined version of her design, the
Trieste. The French Navy eventually replaced her with the bathyscaphe FNRS-4[clarification needed], in the 1960s.[1]
After damage to the FNRS-2 during its sea trials in 1948, the Belgian
Fonds National de la Recherche Scientifique (FNRS) ran out of funding, and the submersible was sold to the French Navy, in 1950. She was subsequently substantially rebuilt and improved at Toulon naval base, and renamed FNRS-3.[2] She was relaunched in 1953, under the command of
Georges Houot, a French naval officer.[3]
On 15 February 1954, she made a 4,050 metres (13,290 ft) dive 160 miles off
Dakar, Senegal, in the Atlantic Ocean, beating the 1953 record of
Auguste Piccard, set by the Trieste, by 900 meters.[2][4][5] Piccard's record had been set by reaching the floor of the Mediterranean off Naples, a depth of 10,392 feet (3,167 m).[4][6] The new record set by FNRS-3 was not exceeded until a workup dive by Trieste in 1959, working up to the record shattering
Challenger Deep dive.[1][4]
