Tambor-type submarines were developed on the basis of the Salmon / Sargo submarines. The rest of the design of the new submarines were close to the prototype, but had a more durable hull and increased armament - 10 torpedo tubes instead of eight submarines "Salmon" and "Sargo". The new two-hull boat could sink to a depth of 90 meters (the design depth of the destruction of the hull was 150 meters). Diesel engines with direct transmission to propeller shafts served as a power plant.
Submarines of the “Tambor” type were built under the 1939 of the fiscal year (SS-198-203) and 1940 of the fiscal year (SS-206-211) programs. Submarines entered into 1939-1941's.
During the war in 1942-1943, submarines of this type underwent modernization - the cabin was replaced with a lower one, which had sponsors to accommodate 40-millimeter bofors and 20-millimeter ров airlikons.
However, there was one "but" ... Adopting the submarines "Tambor", the leadership of the submarine forces was forced to agree to the production of two clearly unsuccessful and do not fit into the strategic concept of using small submarines M. On this concession in December 1941 much regretted as a submarine with a large radius of action was not enough.
Submarines "Tambor" - the last American submarines, adopted by the United States before the entry into the war. With the outbreak of hostilities, these submarines were the main striking force, until they were replaced at the end of 1942 by Gato submarines. Despite this, the Tambor boats remained in the first line until the end of 1944, only after that they were transferred to secondary destinations and training centers. Of the 12 built Tambor boats, the 7 died. Boat SS-199 "Toutog" became the leader in the number of sunk ships and ships of the enemy.
